Imagine this as a morning routine that replaces your first cup of coffee:

You wake up feeling a bit foggy, so you slip on a wearable device that looks like an extra-thick headband. You turn on the power source and settle in while electrical current flows into your brain. Twenty minutes later, feeling more focused and energized, you start your busy day feeling grateful for this new technology.

If this scenario sounds strange to you, I’m with you. And yet, hype around transcranial direct current stimulation (tDCS) is growing for an expanding list of conditions such as depression, ADHD, and even Alzheimer’s disease. A recent ad for one tDCS device urges you to “elevate your performance.” But before you give this a try, read on.

What is transcranial direct current stimulation?

Brain stimulation therapies aim to activate or inhibit parts of the brain. tDCS has been around for years, but its popularity has spiked over the last decade.

tDCS devices use headgear that may look like a swim cap or headband to position electrodes against the scalp. When a power source is switched on, the electrodes deliver low levels of electrical current to the brain. A typical session lasts 20 to 30 minutes and may be repeated over days or weeks.

Three better-known brain stimulation therapies are:

• Transcranial magnetic stimulation (TMS): A device worn over the forehead stimulates specific areas of the brain by changing nearby magnetic fields. TMS is cleared by the FDA to treat depression that hasn’t responded to standard medicines, and for obsessive-compulsive disorder.
• Electroconvulsive therapy (ECT): An electric current flowing through electrodes placed at specific locations on the scalp causes a brief seizure while a patient is under anesthesia. In use since the late 1930s, ECT can be highly effective for severe depression that hasn’t responded to standard therapies. It uses higher levels of electrical current than tDCS. That’s why it requires close medical supervision and is generally administered in a hospital or specialized clinic.
• Deep brain stimulation (DBS): Electrodes surgically implanted in specific areas of the brain generate electrical pulses. DBS is used to treat conditions such as Parkinson’s disease, epilepsy, or tremors that don’t improve with medicines.

What claims are made for tDCS?

The brain normally functions by sending and receiving tiny electrical signals between nerve cells. Stimulating specific regions of the brain with low levels of electricity might improve focus or memory, mood, or even dementia, according to tDCS advocates.

Some claims say tDCS can

• improve mental clarity, focus, and memory
• increase energy and motivation
• relieve so-called brain fog following COVID-19, Lyme disease, or other conditions
• reduce depression or anxiety
• reduce cravings among smokers or people with drug addiction
• improve symptoms of ADHD or Alzheimer’s disease.

Does tDCS work?

The jury is still out. Research suggests that tDCS holds promise for certain conditions, but techniques tested through research may differ from devices sold commercially for at-home use. For example, electrodes may be positioned more precisely over an area of the brain, and how current is delivered, session length, or number of sessions may differ.

Currently, small, short-term studies show that tDCS may benefit people with:

• Depression: An analysis of 10 randomized trials found some participants were more likely to report fewer symptoms of depression, or remission of depression, after a course of tDCS treatment compared with sham treatment.
• Alzheimer’s disease: A review of seven studies found that tDCS lasting 20 to 40 minutes improved memory and other cognitive measures in people with mild to moderate Alzheimer’s disease.
• ADHD: One randomized trial of 64 adults with ADHD found improved attention after 30 minutes of tDCS daily for a month.

The FDA has not cleared tDCS for any health condition, and it is considered investigational. More research with positive results and reassuring safety data are needed before tDCS gets a thumbs-up from regulators.

That’s probably why some ads for tDCS note in fine print that it is not a medical device and is only for recreational use.

Does tDCS have downsides?

While the FDA assesses tDCS as safe for adults, there are downsides to consider. For example, treatment may cause itching, irritation, or small burns at the sites of the electrodes. Some users complain of fatigue or headache.

There are no large, long-term studies of tDCS, so overall safety is uncertain. Some experts believe at-home use raises many questions, such as how much of the brain beyond targeted areas is affected, what inconsistent approaches to tDCS use might do, and how long changes in the brain — intended or not — could last.

Very limited research has been done in children. So, the consequences for a child’s developing brain aren’t clear.

Finally, tDCS devices can be expensive (several hundred dollars or more), and generally are not covered by health insurance.

The bottom line

It’s not yet clear how tDCS should be used, or who is most likely to benefit from it. If you’re interested in pursuing tDCS, understand that there’s still a lot we don’t know.

If you’re more skeptical and risk-averse (like me), you may want to wait for more definitive research regarding its benefits and risks — and for now, stick with your morning coffee to clear your mind.

Many people know the form of dementia called Alzheimer’s disease. But what is frontotemporal dementia (FTD)? Damage to nerves in certain parts of the brain causes a group of frontotemporal disorders, affecting behavior and language as I’ll describe below.

Early signs of frontotemporal dementia

Have you noticed someone behaving differently? Is your coworker doing odd things, such as slapping each door as they walk down the hall? Or has your previously kind and caring spouse lost their capacity for empathy, such that when you told them about your cancer diagnosis, they complained that your treatment schedule would interfere with their golf game? If so, they might be showing early signs of the behavioral variant of FTD.

Maybe there’s a problem with language, rather than behavior. Perhaps it started with difficulty finding words (like any older adult), but is your sibling now having trouble with grammar and getting out an intelligible sentence? Or does your friend not know the meaning of some ordinary words, like pizza, lemonade, wood, or metal? If so, they might be showing signs of primary progressive aphasia, which may also be due to FTD.

A common pathology inside the brain

What’s the connection between these behavior and language problems? Why are they both part of FTD?

Both have the same underlying causes: a family of abnormal proteins that can be seen under the microscope. In fact, more than a dozen different pathologies can cause FTD. Each of them can lead to either behavioral variant frontotemporal dementia or the language difficulties of primary progressive aphasia.

Location, location, location

How can the same pathology — the same abnormal protein — lead to either behavior problems or language problems, or sometimes both? The answer is, it depends on where the pathology is.

The frontal lobes of your brain, behind your forehead, regulate and guide your personality, judgement, and behavior. So, if the frontotemporal pathology is in this region, it will cause changes in personality, judgement, and behavior.

The left temporal lobe (near your left ear and temple) and a part of the left frontal lobe just above it are the critical brain regions for language. When these areas are affected by frontotemporal pathology, language problems develop.

How does frontotemporal dementia compare with Alzheimer’s disease?

Frontotemporal dementia affects people in middle age, usually between ages 45 and 65, although one-quarter of individuals are diagnosed after age 65. Alzheimer’s usually affects people over 65.

In terms of symptoms, people with frontotemporal dementia experience either language or behavior problems, whereas people with Alzheimer’s disease — the most common cause of dementia — usually have memory problems.

Because more than 12 different abnormal proteins can cause frontotemporal dementia, it has a very variable time course. From the time of diagnosis, people with frontotemporal dementia need nursing home–level care in two to 20 years. The typical range with Alzheimer’s disease is four to 12 years.

Who is at risk for FTD?

Up to 40% of cases of frontotemporal dementia run in families, but that means at least 60% of cases do not. Unfortunately, everyone is at risk for frontotemporal dementia as they approach middle age.

What are common signs of the behavioral variant?

There are six common signs of behavioral variant frontotemporal dementia, and most people with the disorder have at least three of them. They are:

• loss of self-control
• apathy or inertia (not wanting to do anything)
• loss of sympathy or empathy
• repetitive or compulsive, ritualistic behavior
• uncontrolled or unusual eating
• difficulty doing complicated tasks.

One individual I cared for with this disorder would walk up to strangers, stand closer than would be comfortable, and say loudly, “You’re handsome!” Another would eat almost anything left out in the kitchen. One woman I treated with this disorder tried to pick up men from a restaurant — while her husband was sitting at the next table. A previously kind and shy grandfather with frontotemporal dementia began to ask his daughter-in-law for sexual favors.

What are common signs of the language variants?

Two variants of primary progressive aphasia are part of the frontotemporal dementia family of diseases. Common signs are:

• difficulty getting words and sentences out, although the meaning of words is preserved (nonfluent or agrammatic variant). People become frustrated because they know what they want to say but find it difficult or impossible to do so.
• losing the meaning of words (semantic variant). I had one patient who did not know the meaning of the words shoe, pants, foot, knee, elbow, and many other words related to clothing and parts of the body.

Can frontotemporal dementia be treated?

Currently, there is no cure or way to slow these disorders down, so treatment is supportive. SSRI medications (selective serotonin reuptake inhibitors) can help with some disinhibited behaviors.

Speech therapy can be helpful, at least initially, with primary progressive aphasia, but thus far no medications are effective.

What can I do if I suspect that someone has frontotemporal dementia?

FTD is difficult to diagnose. Because it affects people in middle age, dementia is usually not suspected. Early in the disease, people are often thought to be having a midlife crisis, depression, or perhaps a drug or alcohol problem. Many marriages end prior to the diagnosis because the spouse with the disorder has grown self-absorbed and inconsiderate over several years.

If you do suspect the disorder, start by simply asking the person if there is anything that you can help with. You may find out that it is another problem entirely. But if it is becoming clear that this or another form of dementia may be involved, encourage them and their family to discuss this possibility with their doctor.

Love isn’t the only reason your heart may skip a beat. While abnormal heartbeats can be alarming, they’re usually harmless. They occur for different reasons. Which types are common — and when should you be concerned?

Palpitations

Your heartbeat normally keeps a predictable pace: speeding up when you’re active and slowing down when you rest. But many people notice odd heart sensations called palpitations at least once in a while. People usually say it feels as though their heart has skipped a beat, or is racing or pounding.

“One common scenario is a person who feels their heart is racing, but if you look at their electrocardiogram (ECG), It’s totally normal,” says cardiologist Alfred E. Buxton, professor of medicine at Harvard Medical School.

A heightened awareness of normal heart rhythms may occur more in people who wear smartwatches with heart rate monitors, he adds. “People with a resting heart rate of 60 beats per minute are concerned when their heart rate goes up to 90, but that’s still in the normal range,” he says.

Ectopic beats

The sensation that your heart has skipped a beat also occurs when the heart’s upper chambers (atria) or lower chambers (ventricles) contract slightly earlier than normal.

During the next beat, the atria pause a bit longer to get back into a normal rhythm. The heart’s lower chambers (ventricles) then squeeze forcefully to clear out the excess blood that accumulates during that pause. They also can contract earlier than usual, which may make you feel like your heart has briefly stopped and restarted.

Known as ectopic beats, both types of these premature contractions may cause a brief pounding sensation. However, this is nothing to worry about. “I often tell my patients that the fact they feel these beats is usually a sign that their heart is healthy. A weak, sick heart can’t exert a forceful beat,” says Dr. Buxton.

AV block and bundle branch block

Electrical impulses tell your heart to pump. They travel through the right and left sides of your heart. But sometimes the impulses travel more slowly than normal or irregularly, causing a condition called AV block. There are various degrees of AV block, some benign, others associated with extremely slow heart rates that may be dangerous.

Another electrical conduction irregularity is a bundle branch block. This results from an abnormal activation pattern of the ventricles that squeeze blood out of the heart to the rest of the body. The most common is right bundle branch block, which usually doesn’t cause obvious symptoms. It may be spotted during an ECG, and can simply reflect the gradual aging of the heart’s conduction system. However, sometimes a right bundle branch block is caused by underlying damage from a heart attack, heart inflammation or infection, or high pressure in the pulmonary arteries.

A left bundle branch block may occur as an isolated phenomenon, or may be caused by a variety of underlying conditions. In some cases, left bundle branch block may lead to abnormal function of the left ventricle, a condition that is sometimes corrected by special pacemakers.

Atrial fibrillation

An electrical misfire in the atria can cause atrial fibrillation, an uncoordinated quivering of the atria that raises the risk for stroke. Commonly known as afib, this heart rhythm problem can come and go, lasting only a few minutes or sometimes for days or even longer. And while some people report a fluttering sensation in their chest or a rapid, irregular heartbeat during an episode of afib, other people don’t have any symptoms.

Certain smartwatches that can record a brief ECG may be able to detect afib. But Dr. Buxton says they’re not sensitive or specific enough to reliably diagnose the problem. “Sometimes the watch tells you that you have afib when you don’t, or vice versa,” he says.

The heart rate monitoring feature may be helpful, however. In people younger than 65, the heart rate can soar to 170 beats per minute or higher during a bout of afib. But for those in their 70s and 80s, who are more likely to have afib, the heart rate usually doesn’t get that high.

When should you be concerned about irregular heartbeats?

An irregular heartbeat, such as racing, fluttering, or skipping a beat, is usually harmless. Even in cases when palpitations are frequent and bothersome (which occurs rarely), reassurance may be the only treatment needed.

But you should contact your doctor if you notice other symptoms accompanying an unusual heartbeat, such as feeling

• chest pain
• dizzy
• lightheaded
• tired
• breathless
• as though you’re going to faint.

People who have been told they have a bundle branch block may need periodic ECGs to monitor their condition. They should also be alert to symptoms such as dizziness or fainting, which can happen if the blockage worsens or occurs on both sides and causes a low heart rate.

It used to be that doctors would automatically recommend treating all men with prostate cancer, even if their initial biopsies suggested the disease would grow slowly (or at all). But during the last several decades, the pendulum on treatment has swung the other way.

Doctors are now likely to advise active surveillance for low- to intermediate-risk cancers that may never turn deadly over the course of a man’s life. Active surveillance involves routine PSA checks, follow-up biopsies, and more recently, magnetic resonance imaging of a patient’s tumor. Treatment is initiated only when — or if — the disease shows signs of progression.

Recent evidence from Johns Hopkins University shows that the long-term risks of metastasis and death from low-grade prostate cancer among men on active surveillance averages just 0.1%. But doctors who care for such men also face a nagging question: which of their patients might have more aggressive cancer that should require closer monitoring? New findings published by the Johns Hopkins team in January provide useful insights.

The researchers’ approach

The researchers in this case zeroed in on the prognostic value of so-called perineural invasion, or PNI, on tumor biopsy samples. PNI simply means that cancer cells are moving into the perineural space between nerves in the prostate and their surrounding tissues. A finding of PNI raises red flags because the perineural space “provides a conduit by which tumor cells can potentially escape the prostate and grow elsewhere in the body,” says Dr. Christian Pavlovich, a urologic oncologist at Johns Hopkins who led the research.

Dr. Pavlovich’s team wanted to know if PNI detected on initial or follow-up biopsies would be associated with higher risks for cancer progression. So they analyzed long-term follow-up data from 1,969 men who had enrolled in an active surveillance research protocol at Johns Hopkins between 1995 and 2021. All the men were diagnosed initially with Grade Group 1 prostate cancer (the least risky form of the disease) and had undergone at least one follow-up biopsy since then.

What did the results show?

Among the 198 men with PNI, 44% of them (87 men in all) eventually progressed to Grade Group 2 prostate cancer, which is a more advanced form of the disease with an intermediate risk of further spread. Conversely, just 26% of the remaining 1,771 men without PNI (461 men) had progressed to Grade Group 2.

Pavlovich emphasizes that despite the new findings, PNI “does not make patients ineligible for active surveillance.” Importantly, the research showed that PNI was not associated with high-risk features, such as cancer in the lymph nodes of patients who wound up having surgery, or post-surgical elevations in PSA that show cancer still lurks in the body.

“What we’ve really shown here is that PNI puts men at a slightly higher risk of extraprostatic extension (cancer cells located just beyond the confines of the prostate),” Pavlovich says. “This is not necessarily a new finding. But PNI only occurs in about 10% of Grade Group 1 patients, and this is the boldest statement yet from the largest study conducted so far.” Pavlovich and his colleagues concluded that PNI provides an inexpensive and readily available indicator for identifying which men on active surveillance will benefit from more intensive monitoring protocols, including MRI and genetic tests.

Dr. Marc B. Garnick, the Gorman Brothers Professor of Medicine at Harvard Medical School and Beth Israel Deaconess Medical Center, agrees, while pointing out that PNI evaluations aren’t performed often enough. A PNI analysis of pathology specimens, he says, “along with emerging and sophisticated genetic testing of the tissue samples, may lead to more certainty in our recommendations to patients.”

Are you having a little trouble hearing conversations? If so, you’re not alone. An estimated 23% of Americans ages 12 and older have hearing loss. Although most of those people have mild hearing loss, for people ages 80 years and older, it’s more common for hearing loss to be moderate to severe than mild.

But not only is moderate to severe hearing loss disruptive to one’s life, it also makes you more likely to develop dementia. A new study helps explain why — and what you can do about it.

What did the new study look at and find?

A study published in JAMA focused on a sample of adults in the United States from the National Health and Aging Trends Study, which follows Medicare beneficiaries. The participants sampled were 70 or older.

The researchers found that about 33% of participants had normal hearing, 37% had mild hearing loss, and 30% had moderate to severe hearing loss. Dementia occurred least often among those with normal hearing (6%), more often among those with mild hearing loss (9%), and most often among those with moderate to severe hearing loss (17%). That’s a large increase in risk, particularly for those whose hearing loss is moderate to severe.

What else to know about this study

The study sample was selected to make it possible to analyze subgroups by age and apply findings to a diverse population. The sample included additional participants ages 90 years and older, and additional participants who identified as Black. Of the 2,413 total participants, 53% were ages 80 years and older, 56% were female, 19% were non-Hispanic Black, 4.5% were Hispanic, and 74% were non-Hispanic white.

Also, unlike previous research, this study looked objectively at hearing loss and dementia. Prior research had shown that hearing loss is thought to account for about 8% of all dementia cases worldwide. Exactly why the connection exists is not known.

It’s important to note that most large studies that found this link were based on questionnaires that people fill out. In other words, no one actually measured the hearing of those participating in the study to make sure that they had hearing loss — or that their hearing was really normal.

In this new study, however, the investigative team used an electronic tablet-based audiometer to evaluate participants’ hearing for four pure tone frequencies that are most important for understanding speech. So, for the first time in a large study, there was objective measurement of hearing loss.

How do hearing aids reduce the risk of dementia?

If you have hearing loss, does that mean you’re doomed to develop dementia? Not at all. This study found that those with moderate to severe hearing loss could significantly reduce their risk of dementia simply by using hearing aids.

This research helps us understand why hearing loss causes dementia. Here’s the connection:

There is increasing evidence that the more the brain is stimulated, the less likely it is that dementia will develop. When there is hearing loss, auditory stimulation is reduced. This, by itself, likely increases dementia risk. But even more important is that when an individual suffers from moderate to severe hearing loss, they are less likely to participate in social activities. Perhaps they are embarrassed about their hearing loss. Or they may simply find it unrewarding to attend a social event when they cannot hear what is going on.

It turns out that social activities are one of the best ways to stimulate the brain, as there is evidence that our brains evolved to facilitate social behavior. Given all this information, you won’t be surprised to learn that reduced social activity has been linked to cognitive decline. Thus, this new study provides additional evidence that the reason hearing loss increases the risk of dementia is because hearing loss reduces brain stimulation — both directly and through reduced social interaction.

What to do if you have hearing loss

Don’t let hearing loss raise your risk of dementia.

• Keep your ears clean. (But remember, never put anything in your ears smaller than your elbow. Ask your doctor if you’re not sure how to clean your ears.)
• If you can’t hear and you don’t have hearing aids, get them. Hearing aids now available over the counter can help many people with mild to moderate hearing loss.
• If you have hearing aids, wear them.
• If your hearing aids aren’t working, get them fixed.
• Don’t be passive — ramp up your social life and other activities.

All these things will help to reduce your risk of dementia. And you might just find that, despite some hearing loss, you’re enjoying life more.

The decision to step down or stop taking a proton pump inhibitor is a complex decision you should discuss with your doctor.

Proton-pump inhibitors (PPIs) are a common type of anti-acid medication, and are available both by prescription and over the counter. Omeprazole and pantoprazole are examples of PPIs. They are the treatment of choice for several gastrointestinal disorders, such as peptic ulcer disease, esophagitis, gastroesophageal reflux disease, and H. pylori infection.

New guidelines by the American Gastroenterological Association have highlighted the need to address appropriate PPI usage, and they recommend that PPIs should be taken at the lowest dose and shortest duration for the condition being treated. However, PPIs are frequently overused, and may be taken for longer than necessary. This can happen unintentionally; for example, if the medication was started while the patient was hospitalized, or it was started as a trial to see if a patient’s symptoms would improve and then is continued beyond the needed timeframe.

Who should use PPIs in the short term?

There are a variety of reasons for short-term PPI usage. For instance, PPIs are prescribed typically for one to two weeks to treat H. pylori infection, in addition to antibiotics. A PPI course of four to 12 weeks may be prescribed for people with ulcers in their stomach or small intestine, or for inflammation in the esophagus.

People may also be prescribed a short course of PPIs for acid reflux or abdominal pain symptoms (dyspepsia), and for symptom relief while physicians perform tests to determine the cause of abdominal pain. People may be able to move to a lower dose of PPIs, or discontinue their medication altogether, if their symptoms get better or they have completed their treatment course.

Who should be on PPIs long-term?

Some patients with specific conditions may need to be on PPIs for the long term, and they should discuss their condition and unique treatment plan with their doctor. Some conditions that may require longer-term use of PPIs include:

• severe esophagitis, eosinophilic esophagitis, Barrett’s esophagus, esophageal strictures, or idiopathic pulmonary fibrosis
• acid reflux
• dyspepsia or upper airway symptoms that improve with PPI usage but worsen when stopping PPIs
• people with a history of upper gastrointestinal bleeding from gastric and duodenal peptic ulcers may need to be on PPIs long-term to prevent recurrence.

What are some side effects of PPIs?

Any medication can cause side effects. Fortunately, adverse effects from PPIs are generally rare. However, these medications have been associated with increased risk of certain infections (such as pneumonia and C. difficile). Previously, there had been concerns that PPI usage was linked to dementia, but newer studies have contradicted this association.

Additionally, while rare, PPIs may also cause drug interactions with other medications. For example, PPIs may affect the levels and potency of certain medications, such as clopidogrel (Plavix), warfarin (Coumadin), and some seizure and HIV medications, sometimes necessitating dosage adjustments of these drugs. Therefore, it is important to let the team of healthcare providers who manage your medications know when a new medication has been added to your list or if a medication has been discontinued.

How do I work with my doctor to step down from taking PPIs?

Some patients are prescribed PPIs twice a day in an acute situation, such as to prevent rebleeding from stomach ulcers or if a patient has severe acid reflux symptoms. If there no longer remains a reason to take PPIs twice a day, you may be stepped down to once a day. To discontinue a PPI, your doctor may decide to taper the medication — for example, by decreasing the dose by 50% each week until discontinued.

What might I experience if my doctor suggests I stop taking a PPI?

Studies have shown that for patients with long-term PPI use, there can be rebound secretion of stomach acid and an increase in upper gastrointestinal symptoms when discontinuing PPIs. However, a different type of anti-acid medication (such as an H2 antagonist like famotidine or a contact antacid medication containing calcium carbonate like TUMS) can be used for relief temporarily. If a patient experiences more than two months of severe persistent symptoms after discontinuing a PPI, this may be a reason to resume PPI therapy.

What steps should I take next?

It is important to routinely discuss your medication list and concerns with your primary care doctor. The decision to step down or discontinue a PPI is complex, and for your safety you should verify with your doctor before adjusting your PPI dosing. Ultimately, the goal is to make sure you are only taking medications that are necessary in order to maximize the benefit and minimize side effects.

The current shortage of semaglutide (Ozempic), an important diabetes drug, has an unusual origin: too many people without diabetes are taking it. Here’s how that happened, and how we might course-correct to help ensure that those with the greatest need for this medicine can get it.

A diabetes drug with an important side effect: Weight loss

Semaglutide (Ozempic) was first approved by the FDA in 2017 to help people with type 2 diabetes keep blood sugar under control. But during pre-approval studies, researchers noticed a remarkable side effect: people lost weight. For example, in one pivotal study, average losses for those receiving one milligram a week of semaglutide were:

• nearly 10 pounds lost over 30 weeks
• nearly 5% overall body weight lost
• waist size shrank 1.6 inches.

This side effect helped people with type 2 diabetes because excess weight is a major risk factor for the condition. Among other health benefits, weight loss can lower blood sugar and blood pressure, and reduce the need for other diabetes medications.

Turning a side effect into a selling point

Unintended weight loss would usually be listed as a side effect for a study medication. But ads for Ozempic didn’t list it with the other possible side effects; instead, it was featured as a benefit. The Ozempic “Tri-Zone” (a phrase concocted by marketers, not medical experts) promised improved blood sugar control, lower cardiovascular risk, and weight loss.

At the bottom of the ad, fine print that’s easy to miss states: “Ozempic is not a weight loss drug.” Talk about mixed messages!

The makers of Ozempic saw the potential of semaglutide as a weight loss drug for people without diabetes. Sure enough, clinical trials confirmed that overweight and obese people taking semaglutide also lost substantial weight. Semaglutide received FDA approval in 2021 for people with obesity (BMI of 30 or greater), or who were overweight (with a BMI of 27 to 29.9) and had a medical problem related to excess weight, such as high blood pressure or high cholesterol. As a weight loss drug, it was rebranded as Wegovy.

The only difference between the two drugs? The maximum approved dose of semaglutide is a bit higher with Wegovy than Ozempic.

How social media fueled the Ozempic shortage

Soon after the approval of Wegovy, celebrities and social media influencers began taking it and sharing glowing weight loss experiences. What’s more, medicines approved for specific uses in the US can be prescribed off-label for any use: up to 38% of all prescriptions written in the US are off-label (note: automatic PDF download). So, it’s likely some of the viral run on Wegovy was fueled by people who wanted to lose weight but had no medical reason to take it.

After high demand put Wegovy in short supply, many turned to Ozempic to lose weight. And that contributed to a shortage of Ozempic, threatening the health of people with type 2 diabetes who rely on the drug.

Readjust priorities and limit irresponsible prescribing

This situation couldn’t have happened without physicians or other health care professionals willing to write Ozempic prescriptions for people who did not have diabetes or another medical reason to use semaglutide. And that suggests an obvious solution: limit prescriptions for Ozempic to people with diabetes. For many drugs, a prior authorization process requires certain conditions be met before a prescription can be filled. This could be done for Ozempic.

And of course, we should encourage people who don’t have diabetes not to request a prescription for Ozempic. While that message is unlikely to show up in a drug ad, public service announcements could do the trick.

The bottom line

Drug ads often urge you to ask your doctor if a treatment is right for you. But we already know a key piece of the answer for Ozempic: if you don’t have diabetes, don’t ask for a diabetes medicine to help with weight loss. There are better ways to get the help you need to reach a healthy weight if you are overweight or obese. Talk to your doctor about a full range of treatment options. And if your weight is already in a healthy range, it’s not a good idea to take a medication to become thinner.

Finally, to keep vitally important medicines available for those who need them most, health care professionals must prescribe them responsibly. Responsible requests by their patients could help.

Feeling rooted in community and socializing with neighbors may strongly contribute to better cardiovascular health by improving diet, exercise habits, and weight control, new research among Black adults in Georgia suggests. And better cardiovascular health may add up to fewer heart attacks and strokes, two leading causes of disability and death.

“There’s a range of interactions within the community that can improve one’s cardiovascular health, not to mention the effect on mental health — the sense of belonging, of being seen — which is tightly related to cardiovascular outcomes in the long run,” says Dr. Dhruv Kazi, director of the cardiac critical care unit at Beth Israel Deaconess Medical Center (BIDMC) and associate director of the Richard A. and Susan F. Smith Center for Outcomes Research in Cardiology.

“Another way to put it is that these unique sources of resilience in communities may directly affect diet, exercise, weight, and mental well-being, all of which lead to improved cardiovascular health,” he adds.

A positive perspective on health within Black communities

The new analysis is part of the ongoing Morehouse-Emory Cardiovascular Center for Health Equity (MECA) study in Atlanta. MECA builds on prior research indicating that living in disadvantaged areas is associated with higher rates of having heart disease or dying from it. But unlike much of that research — which focused on negative aspects of Black neighborhoods that may contribute to poor cardiovascular health — the new study fills a gap. It zeroes in on positive neighborhood features, especially social interactions, that can promote ideal cardiovascular health despite higher risks related to race or socioeconomic status.

“Typically, researchers are identifying factors that result in health disparities on the negative side, such as deaths or co-existing diseases, or that cause increased rates of a particular disease,” explains Dr. Fidencio Saldana, dean for students at Harvard Medical School and an attending physician in medicine and cardiology at Brigham and Women’s Hospital (BWH), whose research interests include racial disparities and outcomes in cardiovascular disease. “It’s quite unique to be able to look for solutions, or to look at these positive attributes of communities and think about how to replicate them.”

Measuring social environment and heart health

The study included 392 Black men and women between the ages of 30 and 70 living in the Atlanta area. None had existing cardiovascular disease. About four in 10 participants were men.

Social environment includes perceptions of neighbors and any support system, as well as how often neighbors interact. Participants answered questions about seven neighborhood features: aesthetics, walking environment, availability of healthy foods, safety, social cohesion, activity with neighbors, and violence.

Heart health was measured using Life’s Simple 7 (LS7) scores, developed by the American Heart Association to determine ideal cardiovascular health. LS7 calculates seven elements that influence cardiovascular health: self-reported exercise, diet, and smoking history, as well as measured blood pressure, sugar level, cholesterol level, and body mass index (BMI). Researchers also gathered information about annual income, education, and marital and employment status, and physical exams that included blood tests.

What did the researchers learn?

After controlling for factors that could skew results, researchers found participants who reported more social connection and activity with neighbors were about twice as likely to record ideal LS7 scores. The association was even stronger among Black women than men.

“Our health is more closely related to these social networks than we appreciate,” Dr. Kazi says, noting that individual efforts to combat obesity and smoking, for instance, are more likely to gain steam “when shared by neighbors.”

“The more we’re able to engage with our neighbors and the communities we live in, the better it probably is for our cardiovascular health,” he says.

The study was observational, so it cannot prove cause and effect. It’s also possible that those who are already healthier are more likely to engage with their neighbors, Dr. Kazi notes. Other limitations are the location of all participants in a single metropolitan area, and the self-reported nature of neighborhood characteristics. Another key area that went unexamined, Dr. Kazi says, involves a “missing piece” in LS7 scores: mental health.

“Living in a community where you feel safe and know your neighbors — where you feel part of the social fabric — is critically important to mental health, and therefore cardiovascular health,” he explains. “If anything, this study underestimates the health benefits of feeling part of a cohesive neighborhood.”

What are a few takeaways from this study?

Social environment and feeling rooted within a community matter to health, and may even help counter negative risk factors. However, long-term lack of investment and the effects of gentrification threaten many Black neighborhoods in cities throughout the US.

“When a neighborhood gets gentrified and longstanding residents are forced to leave, the community is gone forever,” Dr. Kazi adds. “Simply offering the departing residents housing elsewhere doesn’t make up for what is lost. Going forward, we need to be cognizant of the value of community, and invest in our neighborhoods that allow people to safely engage in physical and community activities.”

Dr. Saldana agrees. “Our system is not set up for some communities to have those advantages. It’s important to look to the positive aspects of our communities, and as a system encourage those positive traits in other communities.”

Lifestyle changes like regular exercise, a healthy diet, and sufficient sleep are cornerstones of self-care for people with type 2 diabetes.

But what about mind-body practices? Can they also help people manage or even treat type 2 diabetes? An analysis of multiple studies, published in the Journal of Integrative and Complementary Medicine, suggests they might.

Which mindfulness practices did the study look at?

Researchers analyzed 28 studies that explored the effect of mind-body practices on people with type 2 diabetes. Those participating in the studies did not need insulin to control their diabetes, or have certain health conditions such as heart or kidney disease. The mind-body activities used in the research were:

• yoga
• qigong, a slow-moving martial art similar to tai chi
• mindfulness-based stress reduction, a training program designed to help people manage stress and anxiety
• meditation
• guided imagery, visualizing positive images to relax the mind.

How often and over what time period people engaged in the activities varied, ranging from daily to several times a week, and from four weeks to six months.

What did the study find about people with diabetes who practiced mindfulness?

Those who participated in any of the mind-body activities for any length of time lowered their levels of hemoglobin A1C, a key marker for diabetes. On average, A1C levels dropped by 0.84%. This is similar to the effect of taking metformin (Glucophage), a first-line medication for treating type 2 diabetes, according to the researchers.

A1C levels are determined by a blood test that shows a person’s average blood sugar levels over the past two to three months. Levels below 5.7% are deemed normal, levels from 5.7% to less than 6.5% are considered prediabetes, and levels 6.5% and higher are in the diabetes range.

How can mind-body practices help control blood sugar?

Their ability to reduce stress may play a big part. “Yoga and other mindfulness practices elicit a relaxation response — the opposite of the stress response,” says Dr. Shalu Ramchandani, a health coach and internist at the Harvard-affiliated Benson-Henry Institute for Mind Body Medicine at Massachusetts General Hospital. “A relaxation response can lower levels of the stress hormone cortisol. This improves insulin resistance and keeps blood sugar levels in check, thus lowering A1C levels.”

A relaxation response can help people with diabetes in other ways, such as by improving blood flow and lowering blood pressure, which protects against heart attacks and strokes.

What else should you know about this study?

The results of studies like this suggest a link between various mind-body practices and lower A1C levels, but do not offer firm proof of it. Levels of participation varied widely. But because all mindfulness practices studied had a modest positive effect, the researchers suggested that these types of activities could become part of diabetes therapy along with standard lifestyle treatments.

Could mind-body practices protect people against developing type 2 diabetes, especially for those at high risk? While this study wasn’t designed to look at this, Dr. Ramchandani again points to the long-range benefits of the relaxation response.

“Reducing and managing stress leads to improved moods, and greater self-awareness and self-regulation,” she says. “This can lead to more mindful eating, such as fighting cravings for unhealthy foods, adhering to a good diet, and committing to regular exercise, all of which can help reduce one’s risk for type 2 diabetes.”

Trying mind-body practices

There are many ways to adopt mind-body practices that can create relaxation responses. Here are some suggestions from Dr. Ramchandani:

• Do a daily 10-minute or longer meditation using an app like Insight Timer, Calm, or Headspace.
• Attend a gentle yoga, qigong, or tai chi class at a local yoga studio or community center.
• Try videos and exercises to help reduce stress and initiate relaxation responses.
• Practice slow controlled breathing. Lie on your back with one or both of your hands on your abdomen. Inhale slowly and deeply, drawing air into the lowest part of your lungs so your hand rises. Your belly should expand and rise as you inhale, then contract and lower as you exhale. Repeat for several minutes.

When caught early through routine screening, cervical cancer is curable. In the US, roughly 92% of women with early-stage cervical cancer survive five years or longer, compared with only 17% of women with late-stage cervical cancer. So recent research that shows a steep rise in new cases of advanced cervical cancer among white Southern women, and underscores the disproportionate burden of advanced cases among Black Southern women, is worrisome.

What factors might be at play, and how can people best protect themselves? Two Harvard experts share their insights.

Human papilloma virus and cervical cancer: What to know

Human papilloma virus (HPV) causes nine out of 10 cervical cancers. In 2023, 13,960 women in the US will be diagnosed with cervical cancer and 4,310 will die from it, according to American Cancer Society estimates.

Pap test screening can detect this cancer early, when it’s easiest to treat. And testing for HPV has been approved as an additional screening test for cervical cancer. It can be used alone or with a Pap test.

What did the research focus on and learn?

The study was published online in International Journal of Gynecological Cancer. Researchers combed through cervical cancer data submitted to the United States Cancer Statistics program between 2001 and 2018, and national survey findings on Pap screening and HPV vaccination. During this period, nearly 30,000 women were diagnosed with late-stage cervical cancer, which has spread to other parts of the abdomen and body.

Early-stage cervical cancer cases have been dropping for most groups in the US in recent years. But advanced cervical cancer cases have not declined within any US racial, ethnic, or age group over the last 18 years.

New diagnoses of advanced disease rose 1.3% annually during the study period. Southern white women ages 40 to 44 saw an annual rise of 4.5% in advanced cases. Southern Black women ages 55 to 59 were diagnosed nearly twice as often as white women with early and advanced cases.

What else is important to understand?

The new study showed that women living in the South are less likely to be vaccinated against HPV or screened for cervical cancer. But lower screening rates likely don’t fully explain the rise in late-stage cases in that region, says Dr. Ursula Matulonis, chief of the Division of Gynecologic Oncology at Dana-Farber Cancer Institute.

“Most cervical cancer cases continue to be diagnosed early,” Dr. Matulonis says. “These new findings suggest that cases involving a more aggressive cell type called adenocarcinoma are also increasing. Often found higher up in the cervical canal, this is harder to detect with a Pap smear.”

Older women are especially vulnerable. Rates of late-stage cervical cancer are higher — and survival is worse — among women 65 and older than among younger women, according to a study in California. One possible reason? They may not have received the recommended number of screening tests with normal results before they stopped having Pap smears, says Dr. Sarah Feldman, a gynecologic oncologist at Brigham and Women’s Hospital.

HPV vaccine protects against cervical cancer

The HPV vaccine is FDA-approved for use in females ages 9 through 26. The first group of vaccinated adolescents, now in their 20s, have clearly benefited: invasive cervical cancer rates among women 20 to 24 dropped by 3% each year from 1998 through 2012.

“That’s pretty impressive,” Dr. Matulonis says. “And those decreases span race and ethnicity, which isn’t always the case in women’s cancers.”

What steps can you take to protect against cervical cancer?

Dr. Feldman offers this guidance around cervical cancer prevention and detection.

• HPV vaccination. All children should be vaccinated against HPV between ages 9 and 12, well before sexual activity begins. “The most important thing for future generations in cervical cancer prevention is vaccinating that generation,” Dr. Feldman says.
• Routine screening. Regardless of vaccination status or whether they’re sexually active, women should begin having screening tests for cervical cancer in their 20s and continue through age 65. Discuss the right intervals with your doctor. Current screening guidelines take into account when you start screening and whether results of tests are normal:
  • If you start at 21: Have a Pap test every three years until 30.
  • If you start at 25: Seek an HPV test first.
  • At age 30: If all screening tests so far have been normal, have HPV testing every five years. Continue this screening until age 65.
  • Don’t stop screening at 65 unless all test results are normal, including at least two results in the last 10 years and one in the last five years.
  • If any testing led to abnormal results, you may need to continue screening beyond age 65.

An HPV infection, rather than sexual activity alone, is the factor that places people at risk, Dr. Feldman says.

“A lot of older women may have a new sexual partner in their 50s. A new HPV infection raises risk for cervical cancer roughly 20 years later,” Dr. Feldman says. “If HPV test results are persistently negative through age 65, the risk of developing cervical cancer in your 70s is low.”

A positive outlook has been linked to better heart health and a longer life. But is that true for Black Americans, whose average lifespan is about 72 years, compared with an average lifespan of 77 years for all Americans?

Recent findings from the nation’s largest and longest-running study of cardiovascular risk factors in Black Americans, the Jackson Heart Study, suggest that the answer is a qualified yes. Cardiovascular diseases, which give rise to heart attack and stroke, are the leading cause of death and disability worldwide. Perhaps not surprisingly, the association between optimism and longevity in Black Americans appears to be strongest among people with higher education or income levels, and those ages 55 and younger. It also proved stronger among men than among women.

Is optimism the only key to longevity in this study?

Probably not. There’s another possible explanation for the findings, says Dr. Rishi Wadhera, a cardiologist at Harvard-affiliated Beth Israel Deaconess Medical Center (BIDMC).

“Instead of optimism leading to better health, it’s possible that healthier individuals are simply more optimistic, or less healthy individuals are less optimistic,” he says. This so-called reverse causality — when cause and effect are the opposite of what one assumes — is always a possibility in observational studies, even when scientists take pains to control for possible confounding factors such as health conditions and behaviors, as they did in this study.

“Nonetheless, these findings contribute to a body of evidence that suggests that psychosocial resources, mood, and mental health are all associated with health,” says Dr. Wadhera, who is section head of health policy and equity research at the Richard A. and Susan F. Smith Center for Outcomes Research in Cardiology at BIDMC.

Measuring optimism in the study

Led by researchers at the Harvard T.H. Chan School of Public Health, the study included 2,652 women and 1,444 men who were part of the Jackson Heart Study. Researchers measured optimism using the Life Orientation Test-Revised, which includes questions such as “In uncertain times, I usually expect the best.” Responses are scored on a scale of 0 (strongly disagree) to 4 (strongly agree). The researchers administered this test and others between 2000 and 2004, and tracked mortality among the study participants until 2018.

Optimism — the general belief that good things will happen — may be partly inherited, although genetic factors are thought to explain only about 20% to 30% of this trait. Some research suggests that people can enhance their feelings of optimism either through cognitive behavioral therapy or writing exercises that focus on imagining their “best possible future self.”

Looking forward

Still, optimism is but one of many intertwined social factors that influence how long people live. A better understanding of biological pathways that could potentially explain the outcomes observed in this study may help, says Dr. Wadhera.

“But to meaningfully address the alarming and ubiquitous health inequities that exist in our country, we need to tackle the unacceptable gaps in care and resources that exist between different racial and ethnic groups,” he adds. This includes disparities in health insurance coverage, access to health care, neighborhood factors such as access to green space and healthy foods, and environmental stressors such as pollution exposure. “Doing so may help people and communities from all backgrounds live happier and longer lives,” Dr. Wadhera says.

 

Understandably, the sensitive topic of weight in children and teens often focuses on the health costs of overweight and obesity. Sometimes, though, a child needs to gain some weight. And while there are lots of ways to make that happen, not all of them are healthy.

What to do if your child seems underweight

If you are worried about whether your child needs to gain weight, it’s very important to check with your doctor before getting to work on fattening them up. It’s entirely possible that your child’s weight is absolutely fine. Given that one in five children in the US is obese and another one in six is overweight, it’s easy to see how a parent might think their child is too thin in comparison. One way to find out if your child’s weight is healthy is to check their body mass index, a calculation using height and weight that is used for children ages 2 and up.

Losing weight or being underweight can be a sign of a medical or emotional problem, so be sure to let your doctor know about your concerns. They may want to see your child to help decide if any evaluations are needed. If your child is less than 2 years old, it’s particularly important that you check in with your doctor about weight concerns, and follow their advice exactly.

Choosing healthy foods when a child needs to gain weight

If your child is older than 2 and the doctor agrees that gaining weight is a good idea, the best way to approach it is by using healthy foods and healthy habits.

Three ways to help encourage healthy weight gain:

• Give your child three meals (breakfast, lunch, and dinner) and two healthy snacks (mid-morning and mid-afternoon). If your child eats dinner early, you could consider a small snack before bedtime. Try to avoid snacks in between or drinking anything other than some water; you want them to be hungry when you give them food.
• Offer healthy high-calorie foods. Think in terms of healthy fats and protein. Some examples are:
  • nuts and nut butters, as well as seeds like pumpkin or sunflower seeds
  • full-fat dairy, such as whole milk, heavy cream, cream cheese, and other cheeses
  • avocados
  • hummus
  • olive oil and other vegetable oils
  • whole grains, such as whole-wheat bread or granola (look for granola sweetened with juice or fruit rather than sugar)
  • meat if your diet includes it
• Every time you prepare a meal or snack, think about how you might add some calories to it. For example, you could add some extra oil, butter, or cheese to pasta — or some nut butter on a slice of apple or piece of toast.

Three traps to avoid:

• Giving your child more sweets or junk food. It’s tempting, as children generally want to eat sweets and junk food, and both have calories. But they aren’t healthy foods, and it’s not a good idea to build a sweets and junk food habit.
• Giving your child unlimited access to food. This, too, is tempting — after all, you want them to eat! But not only does that make it hard to be sure that what they are eating is healthy, snacking can make them less hungry when it’s time for an actual meal.
• Letting your child fill up on milk and other drinks — including nutritional supplement drinks. This, too, makes it less likely that they will eat at mealtime, and they are unlikely to get all the nutrients they need. Don’t give your child nutritional supplements unless your doctor advises you to do so.

Be sure you schedule regular check-ins with your doctor to monitor your child’s progress. Hopefully your child will soon be at a healthier weight that helps them to thrive as they grow.

Infertility is a remarkably common problem. It affects up to one in five people in the US who are trying to become pregnant, and 186 million people worldwide. A thorough medical evaluation can spot key contributing issues in many cases — whether in a woman, a man, or both partners — that might respond to treatment, or call for assisted reproductive tools like in vitro fertilization (IVF).

But in a substantial number of cases, no cause is found for infertility. Could inflammation be to blame for some of those cases, as recent research suggests? And if so, will an anti-inflammatory diet or lifestyle boost fertility?

Exploring the connection between inflammation and infertility

Chronic inflammation has been linked to many health conditions, such as cardiovascular disease, stroke, and cancer.

While its importance in infertility is far from clear, some evidence supports a connection:

Could an anti-inflammatory diet improve fertility?

It’s a real possibility. Decades ago, researchers observed that women following a prescribed fertility diet ovulated more regularly and were more likely to get pregnant. Now a 2022 review of multiple studies in Nutrients suggests that following an anti-inflammatory diet holds promise for people experiencing infertility. The research was done years apart, but the diets in these two studies share many elements.

The 2022 review found that an anti-inflammatory diet may help

• improve pregnancy rates (though exactly how is uncertain)
• increase success rates of assisted reproductive measures, such as IVF
• improve sperm quality in men.

The authors add that improving diet might even reduce the need for invasive, prolonged, and costly fertility treatments. However, the quality of studies and consistency of findings varied, so more high-quality research is needed to support this.

Will adopting an anti-inflammatory lifestyle improve fertility?

While recent research is intriguing, there’s not enough evidence to show that an anti-inflammation action plan will improve fertility. A plant-based diet such as the Mediterranean diet, and other measures considered part of an anti-inflammatory lifestyle, improve heart health and have many other benefits.

It’s not clear if this is directly due to reducing inflammation. But this approach comes with little to no risk. And abundant convincing evidence suggests it can improve health and even fight disease.

What is an anti-inflammatory lifestyle?

Health experts have not agreed on a single definition. Here are some common recommendations:

• Adopt a diet that encourages plant-based foods, whole grains, and healthy fats like olive oil while discouraging red meat, highly processed food, and saturated fats.
• Stop smoking or vaping.
• Lose excess weight.
• Be physically active.
• Get enough sleep.
• Treat inflammatory conditions, such as rheumatoid arthritis or allergies.
• Avoid excessive alcohol consumption.
• Control stress.

Anti-inflammatory medicines may help in certain situations — for example, treatments for autoimmune disease. However, they are not warranted for everyone. And for people trying to conceive, it’s far from clear that any potential benefit would exceed the risk of side effects for parent and child.

The bottom line

It’s possible that inflammation plays an important and underappreciated role in infertility and that an anti-inflammatory diet or lifestyle could help. But we need more evidence to confirm this. Until we know more, taking measures to improve your overall health and possibly reduce chronic inflammation makes sense.

There is no definitive evidence yet that microdosing with psychedelics is either effective or safe.

Psychedelic drugs have been capturing the attention of doctors and patients alike, for their increasingly proven potential to effect long-lasting improvements in the mental health of people who are suffering from conditions such as treatment-resistant depression. Microdosing of psychedelic substances such as LSD or psilocybin involves taking a fraction of a regular dose (a subperceptual dose) that is much lower than one would take if one wanted to “trip” or hallucinate on these substances.

Many people share the idea that microdosing with psychedelics enhances one’s mood, creativity, concentration, productivity, and ability to empathize with others. Or could the benefits be an “expectancy effect”? This means that most people who take a daily pill that they fervently expect will help them feel happier and smarter will feel like they are happier and smarter — just from taking the pill, regardless of what’s in it.

What is microdosing?

There isn’t a single, clearly recognized definition of microdosing for any psychedelic drug, and this complicates attempts to perform consistent research. One definition is approximately 1/5 to 1/20 of a recreational dose. (From anecdotal experience this is accurate, as a medium-strength dose of psilocybin is 2 to 3 grams of dried mushrooms, and a microdose is typically around 0.3 grams.) One obstacle is that the potency of mushrooms can vary greatly, as they are not regulated outside of clinical trials, so this isn’t an exact science. Likewise, LSD is an invisible, tasteless, odorless substance that usually comes either in liquid form or embedded into a piece of paper to be slipped under the tongue.

Given its current illegality and lack of regulation, there is no good way to know what dosage you are taking unless you have an extraordinarily reliable supplier. LSD is an extremely powerful and long-acting drug, and you don’t want to take more of it than intended. Further, psychedelics such as psilocybin and LSD can produce physiological tolerance, which might suggest that, even if microdosing does help, there could be diminishing returns if one stays at the same dosage.

Is microdosing safe?

We don’t know as much about safety as we might have learned if not for the War on Drugs, which curtailed much of the research into psychedelics starting in the late 1960s. This research has been renewed over the last five to 10 years, and many medical centers are conducting research on psychedelics. Psilocybin is generally thought to be safe in low dosages and has been used for centuries by indigenous peoples. However, if one takes too large a dose it can result in a terrifying — even traumatic — experience.

Psilocybin is a compound produced by almost 200 species of fungi (mushrooms), and the mushrooms must come from a trusted source. It is very easy to poison oneself with the wrong type of mushroom, as there are many types of mushrooms in nature that can look quite similar to each other, but some are poisonous and can harm your liver, causing severe illness or even death.

Could psychedelics become safer if legalized?

It is anticipated by experts in the field that some psychedelics may become fully legalized — for medical usage, under supervision — within the next few years, specifically psilocybin and MDMA (ecstasy). Some policy makers and public health experts believe that the safety of these psychedelics would be enhanced if they were decriminalized, and if their cultivation and production were monitored and regulated. At least one state (Oregon), and many cities around the country, have decriminalized psychedelics at the local level.

Some advocates of decriminalization are looking forward to a safer product, and wider access that could include not having to see a medical professional to get a prescription or be under medical supervision when using psychedelics. Skeptics are worried that uncontrolled access to these drugs might affect patients with mental illness, or might even precipitate mental illness such as psychosis in people that are vulnerable.

It is important to mention that the use of all psychedelic drugs should be undertaken with utmost caution — if they should be used at all — in patients with major mental illness such as schizophrenia or bipolar disorder. For safety reasons, these patients are typically excluded from studies involving psychedelic drugs.

Evidence for microdosing of psychedelics is mixed

Does microdosing work? In short, the jury is still out. Some studies indicate a very real and significant benefit from microdosing, whereas others are much less convincing and show little to no benefit. One recent study used a naturalistic, observational design to study 953 psilocybin microdosers compared with 180 nondosing participants for 30 days, and found “small to medium-sized improvements in mood and mental health that were generally consistent across gender, age, and presence of mental health concerns.” This study and others like it appear to confirm many anecdotal reports of people who swear by the benefits they have experienced from microdosing.

Other studies on microdosing are far less impressive. In one example the researchers conducted a randomized controlled study, which represents the strongest type of evidence because it weeds out the placebo effect. The researchers took 34 patients and randomized half of them to receive psilocybin and half to placebo. While there were some intriguing subjective effects (people felt happier and more creative), and even some changes in brain waves recorded on an EEG machine, they concluded that low-dose psilocybin mushrooms did not show objective evidence of improvements in creativity, well-being, and cognitive function. Studies such as this one support the hypothesis that the effect people receive from psychedelics at these subperceptual doses is mostly an expectancy effect, and that one needs to consume a higher dosage to receive a therapeutic benefit.

To microdose or not to microdose?

While any medical or lifestyle decision is an individual’s choice (assuming that they aren’t harming others), I would highly recommend that you speak with your doctor to explore your decision to take psychedelics, and see if there are any medical reasons why you should be cautious or avoid these drugs. It is critical to pay attention to the legality and the quality of your product — you likely can’t afford to get into legal jeopardy, and certainly can’t afford to poison yourself.

Finally, it is important to understand that there isn’t yet definitive proof that microdosing is at all helpful, or even that it is safe in the long term. With these points in mind, it is fair to say that psychedelic drugs are becoming better understood, and are undergoing a resurgence of research and a more widely accepted use.

The wait is finally over: after 40 weeks of medical appointments, nursery planning, and anticipation, your baby has finally arrived. She is perfect in your eyes, healthy and adorable. Yet over the next few weeks, your initial joy is replaced by all-consuming worries: Is she feeding enough? Why is she crying so often? Is something medically wrong with her? These worries are constant during the day and keep you up at night. You feel tense and irritable, your heart races, and you feel panicky. Your family members start to express their concern —not just about the baby, but about you. You wonder whether your anxiety is normal.

Baby blues, postpartum depression, or postpartum anxiety?

Chances are, you have heard about the baby blues or postpartum depression. You may have even filled out questionnaires about your mood during your postpartum doctor’s visit. The baby blues are a very common reaction to decreasing hormone levels after delivery, and may leave you feeling sad, weepy, and overwhelmed. However, these symptoms are mild and only last for a couple of weeks. When the symptoms persist and become debilitating, something else could be going on.

Many symptoms overlap between postpartum depression and postpartum anxiety (such as poor sleep, trouble relaxing, and irritability). Mothers experiencing postpartum depression commonly experience symptoms of anxiety, although not all mothers suffering from anxiety are depressed. Establishing the correct diagnosis is important, as women with postpartum anxiety may not respond as well to certain treatments for depression, such as interpersonal psychotherapy or medications such as bupropion (Wellbutrin).

Similar to postpartum depression, postpartum anxiety may spike due to hormonal changes in the postpartum period. It may also increase as a response to real stressors — whether it’s the health of the baby, finances, or in response to navigating new roles in your relationships. A history of pregnancy loss (miscarriage or stillbirth) also increases your risk for developing postpartum anxiety. If you have a history of anxiety before or during pregnancy, postpartum anxiety symptoms may also return after delivery. Anxiety and sadness may also appear after weaning from breastfeeding due to hormonal changes.

Some women experience panic attacks or symptoms of obsessive-compulsive disorder (OCD) in the postpartum period. Panic attacks are distinct episodes of intense anxiety accompanied by physical symptoms including a rapidly beating heart, feelings of doom, shortness of breath, and dizziness. Obsessions are intrusive, unwanted thoughts and may be accompanied by compulsions, or purposeful behaviors to relieve distress. These symptoms may be frightening to a new mother, especially when these thoughts involve harming the baby. Fortunately, when obsessions are due to an anxiety disorder, mothers are extremely unlikely to harm their babies.

What are the treatments for postpartum anxiety?

In general, postpartum anxiety is less studied than its cousin postpartum depression; however, it is estimated that at least one in five women has postpartum anxiety. We do know that therapies such as cognitive behavioral therapy (CBT) are excellent treatments for anxiety disorders, including OCD. For some women, medications can be helpful and are more effective when combined with therapy. Selective serotonin reuptake inhibitors (SSRIs) are generally the first-line medications (and the best studied medication class) for anxiety disorders, whereas benzodiazepines are rapidly acting anti-anxiety medications that are often used while waiting for an SSRI to take effect.

Should you take medications when breastfeeding?

Breastfeeding provides many benefits to the baby: it’s the perfect nutrition, it helps build a baby’s immune system, it may help prevent adulthood obesity, and it provides comfort and security. Breastfeeding also provides benefits for the mother: it releases prolactin and oxytocin (the love and cuddle hormones), which help a mother bond with her baby and provide a sense of relaxation. When considering whether to start a medication, it is important to be aware that all psychiatric medications are excreted into the breast milk. Your doctor can help you think through the risks and benefits of medications based on the severity of your illness, medication preference, and previous response, as well as factors unique to your baby, such as medical illness or prematurity.

What non-medication strategies are helpful in decreasing postpartum anxiety?

• Cuddle your baby (a lot). This releases oxytocin, which can lower anxiety levels.
• Try to maximize sleep. Although the baby may wake you every three hours (or 45 minutes) to feed, your partner should not. Sleeping in separate rooms or taking shifts caring for the baby may be necessary during the first few months. Aim for at least one uninterrupted four-hour stretch of sleep, and be mindful about caffeine intake.
• Spend time with other mothers. Although you may feel like you don’t have the time, connecting with other mothers (even online) can do wonders in lowering your fears and validating your emotions. Chances are you are not the only one worrying up a storm.
• Increase your physical activity. In spite of the physical toll that pregnancy, delivery, and milk production take on your body, physical activity is one of the most powerful anti-anxiety strategies. Activities that incorporate breathing exercises, such as yoga, may be particularly helpful.
• Wean gradually. If you are breastfeeding and make the decision to wean, try to do so gently (when possible) to minimize sudden hormonal changes.
• Ask for help. Caring for a baby often requires a village. If you are feeding the baby, ask someone else to help with household chores. There is an old saying “sleep when the baby sleeps.” You may prefer “do laundry when the baby does laundry.”

And finally, give yourself a break — after all, you just had a baby. Postpartum anxiety is common, and in many cases, it will pass with time.
