Are online gambling and sports betting new to your area? Are gambling advertisements catching your eye? Have you noticed sports and news shows covering the spread? Recent changes in laws have made gambling widely accessible, and its popularity has soared.

Occasional bets are rarely an issue. But uncontrolled gambling can lead to financial, psychological, physical, and social consequences, some of which are extreme. Understanding whether gambling is becoming a problem in your life can help you head off the worst of these issues and refocus on having more meaning, happiness, and psychological richness in your life. Gambling screening is a good first step.

Can you screen yourself for problem gambling?

Yes. Screening yourself is easy. The Brief Biosocial Gambling Screen (note: automatic download) is a validated way to screen for gambling disorder. It has three yes-or-no questions. Ask yourself:

• During the past 12 months, have you become restless, irritable, or anxious when trying to stop/cut down on gambling?
• During the past 12 months, have you tried to keep your family or friends from knowing how much you gambled?
• During the past 12 months, did you have such financial trouble as a result of your gambling that you had to get help with living expenses from family, friends, or welfare?

What do your answers mean?

Answering yes to any one of these questions suggests that you are at higher risk for experiencing gambling disorder. Put simply, this is an addiction to gambling. Like other expressions of addiction, for gambling this includes loss of control, craving, and continuing despite bad consequences. Unique to gambling, it also often means chasing your losses.

A yes doesn’t mean that you are definitely experiencing a problem with gambling. But it might be valuable for you to seek a more in-depth assessment of your gambling behavior. To find an organization or person qualified to help, ask a health care provider, your local department of public health, or an advocacy group like the National Council on Problem Gambling.

Are you ready for change?

Your readiness to change a behavior matters when deciding the best first steps for making a change. If someone asks you whether you want to change your gambling, what would you say?

I never think about my gambling.

Sometimes I think about gambling less.

I have decided to gamble less.

I am already trying to cut back on my gambling.

I changed my gambling: I now do not gamble, or gamble less than before.

Depending on your answer, you might seek out different solutions. What’s most important initially is choosing a solution that feels like the right fit for you.

What if you don’t feel ready to change? If you haven’t thought about your gambling or only occasionally think about changing your gambling, you might explore lower intensity actions. For example, you could

• read more about how gambling could create a problem for you
• listen to stories of those who have lived experience with gambling disorder.

If you are committed to making a change or are already trying to change, you might seek out more engaging resources and strategies to support those decisions, like attending self-help groups or participating in treatment.

Read on for more details on choices you might make.

What options for change are available if you want to continue gambling?

If you want to keep gambling in some way, you might want to stick to lower-risk gambling guidelines:

• gamble no more than 1% of household income
• gamble no more than four days per month
• avoid regularly gambling at more than two types of games, such as playing the lottery and betting on sports.

Other ways to reduce your risk of gambling harm include:

• Plan ahead and set your own personal limits.
• Keep your entertainment budget in mind if you decide to gamble.
• Consider leaving credit cards and debit cards at home and use cash instead.
• Schedule other activities directly after your gambling to create a time limit.
• Limit your use of alcohol and other drugs if you decide to gamble.

What are easy first steps toward reducing or stopping gambling?

If you’re just starting to think about change, consider learning more about gambling, problem gambling, and ways to change from

• blogs, like The BASIS
• books like Change Your Gambling, Change Your Life
• podcasts like After Gambling, All-In, and Fall In, which offer expert interviews, personal recovery stories, and more.

Some YouTube clips demystify gambling, such as how slot machines work, the limits of skill and knowledge in gambling, and how gambling can become an addiction. These sources might help you think about your own gambling in new ways, potentially identifying behaviors that you need to change.

What are some slightly more active steps toward change?

If you’re looking for a slightly more active approach, you can consider engaging in traditional self-help experiences such as helplines and chatlines or Gamblers Anonymous.

Another option is self-help workbooks. Your First Step to Change is a popular workbook that provides information about problem gambling, self-screening exercises for gambling and related conditions like anxiety and depression, and change exercises to get started. A clinical trial of this resource suggested that users were more likely than others to report having recently abstained from gambling.

Watch out for gambling misinformation

As you investigate options, keep in mind that the quality of information available can vary and may even include misinformation. Misinformation is incorrect or misleading information. Research suggests that some common types of gambling misinformation might reinforce harmful beliefs or risky behaviors.

For example, some gambling books, websites, and other resources exaggerate your likelihood of winning, highlight win and loss streaks as important (especially for chance-based games like slots), and suggest ways to change your luck to gain an edge. These misleading ideas can help you to believe you’re more likely to win than you actually are, and set you up for failure.

The bottom line

Taking a simple self-screening test can start you on a journey toward better gambling-related health. Keep in mind that change can take time and won’t necessarily be a straight path.

If you take a step toward change and then a step back, nothing is stopping you from taking a step forward again. Talking with a care provider and getting a comprehensive assessment can help you understand whether formal treatment for gambling is a promising option for you.

The daily bath or shower is a routine for many of us — and for our children, too. But is it really necessary?

The short answer is no.

Obviously, there are days when washing up makes good sense — like if your child is grimy from a day in the dirt; covered in sweat, paint, or other visible dirt; or had an explosive poop. It’s also a good idea to wash up if your child has spent the day in a pool (the chlorine may be irritating to the skin), a body of water (there could be things in the water that are irritating or unhealthy), or used bug spray to ward off ticks and mosquitoes. And certainly, it’s best for everyone in the vicinity when a stinky teenager takes a soapy shower.

Sometimes a doctor may recommend daily bathing for certain skin conditions. And we all need to wash our hands regularly to prevent infection. But full-body washing just for the sake of washing? Not so much.

Why not bathe a child daily?

Lots of bathing can lead to dry, irritated skin. But also, the skin has natural protective oils, and natural bacteria, that help to keep us healthy and safe — and that can get washed away with daily bathing.

If your baby or preteen looks pretty clean, isn’t stinky, isn’t covered in bug spray, and hasn’t been in a pool or other body of water, it’s fine to skip the bath or shower. Really, bathing two or three times a week is fine. In fact, for many kids, even just once or twice a week is fine. You can always do a quick wipe with a wet washcloth to the face, groin area, and any dirty spots.

Stinky teenagers might need more bathing or showering, depending on activity level and deodorant use. But even they may be able to get away with washing their face and using a soapy washcloth on their groin and underarms.

Tips for healthy bathing

When you do bathe children, here are some tips for healthy bathing.

• Don’t use hot water — use warm water instead.
• Keep it short — preferably just enough time to get the washing done.
• Avoid antibacterial soaps and bubble baths. Use mild, unscented soap and shampoo.
• Make sure bathing is supervised for all babies and young children.
• Pat dry rather than rubbing dry. If your child tends to have dry skin, using a mild, unscented greasy moisturizer after the bath can be helpful.

If your child has eczema or any other skin condition, check with your doctor to get tailored advice for bathing your child.

As the adage goes, the eyes are the windows to the soul. So what does it mean to wish yours were a different color?

Apparently enough people share this desire to create a bustling market for color-changing eye drops, which are making the rounds through social media and online retailers.

Personalizing eye color might sound tempting, especially for younger people and those who enjoy experimenting with elements of fashion or style. But are over-the-counter, color-changing eye drops safe? The answer is a hard no, according to the American Academy of Ophthalmology (AAO), which recently issued a warning against “eye color-changing solutions.”

Why shouldn’t you try color-changing eye drops?

Color-changing eye drops aren’t approved by the FDA, haven’t been tested for safety or effectiveness, and could potentially damage people’s eyes, the AAO warns.

“It might seem benign when you see a product like this online,” says Dr. Michael Boland, an associate professor of ophthalmology and glaucoma specialist at Harvard-affiliated Mass Eye and Ear. “People think, ‘Why not try it?’.” “But there’s no way to know what’s in these bottles and no oversight over how they’re being made.”

How do the eye drops work?

That’s not clear. Companies manufacturing the drops claim the products adjust levels of melanin in the iris, the colored portion of the eyeball. Purportedly, the effects begin to be visible within hours and can last for a week or longer. If a user wants enduring results, they’ll need to continue using the product.

But these claims skirt a complete lack of evidence that the drops have any effects on the iris, much less the desired effects, Dr. Boland says.

“I’ve found zero descriptions of how they work in terms of a plausible mechanism,” he says. The ingredients list includes things that might be found in other eye drops or drugs or even cosmetics, but nothing that would actually change your eye color.”

How might the drops hurt your eyes?

The AAO lists a variety of potential safety risks from using these products or any other unregulated eye drops, including:

• inflammation
• infection
• light sensitivity
• increased eye pressure or glaucoma
• permanent vision loss.

“All of those problems are possible, since we don’t have any real idea what’s in these bottles,” Dr. Boland says. “The biggest concern is damage to the cornea, the clear part of the front of the eye. If the cornea is damaged by the chemicals in those bottles, you might lose vision.”

Are there safe alternatives to change eye color?

Still hankering for a way to get, say, Taylor Swift’s electric blue eyes or Julia Roberts’ golden brown peepers? There is a trustworthy option, Dr. Boland says: colored contact lenses. But he recommends choosing that option with caution.

“Professionally prescribed and dispensed contact lenses are a safe way to change your eye color,” he says. “But don’t buy them online. Get them from a reputable source to make sure they’ve been regulated and evaluated as safe, because contacts can damage the eye if they’re not designed properly or kept clean.”

Not so long ago, a friend texted me from a coffee shop. He said, "I can't believe it. I'm the only one here without a tattoo!" That might not seem surprising: a quick glance around practically anywhere people gather shows that tattoos are widely popular.

Nearly one-third of adults in the US have a tattoo, according to a Pew Research Center survey, including more than half of women ages 18 to 49. These numbers have increased dramatically over the last 20 years: around 21% of US adults in 2012 and 16% of adults in 2003 reported having at least one tattoo.

If you're among them, some recent headlines may have you worried:

              Study Finds That Tattoos Can Increase Your Risk of Lymphoma (OnlyMyHealth)

              Getting a Tattoo Puts You At Higher Risk of Cancer, Claims Study (NDTV)

              Inky waters: Tattoos increase risk of lymphoma by over 20%, study says (Local12.com)

              Shocking study reveals tattoos may increase risk of lymphoma by 20% (Fox News)

What study are they talking about? And how concerned should you be? Let's go through it together. One thing is clear: there's much more to this story than the headlines.

Why are researchers studying a possible link between tattoos and lymphoma?

Lymphoma is a type of cancer that starts in the lymphatic system, a network of vessels and lymph nodes that twines throughout the body. With about 90,000 newly diagnosed cases a year, lymphoma is one of the most common types of cancer.

Risk factors for it include:

• advancing age
• certain infections (such as Epstein-Barr virus, HIV, and hepatitis C)
• exposure to certain chemicals (such as benzene, or possibly pesticides)
• family history of lymphoma
• exposure to radiation (such as nuclear reactor accidents or after radiation therapy)
• having an impaired immune system
• certain immune diseases (such as rheumatoid arthritis, Sjogren's disease, or celiac disease).

Tattoos are not known to be a cause or risk factor for lymphoma. But there are several reasons to wonder if there might be a connection:

• Ink injected under the skin to create a tattoo contains several chemicals classified as carcinogenic (cancer causing).
• Pigment from tattoo ink can be found in enlarged lymph nodes within weeks of getting a tattoo.
• Immune cells in the skin can react to the chemicals in tattoo ink and travel to nearby lymph nodes, triggering a bodywide immune reaction.
• Other triggers of lymphoma, such as pesticides, have a similar effect on immune cells in lymph nodes.

Is there a connection between tattoos and lymphoma?

Any potential connection between tattoos and lymphoma has not been well studied. I could find only two published studies exploring the possibility, and neither found evidence of a compelling link.

The first study compared 737 people with the most common type of lymphoma (called non-Hodgkin's lymphoma) with otherwise similar people who did not have lymphoma. The researchers found no significant difference in the frequency of tattoos between the two groups.

A study published in May 2024 — the one that triggered the scary headlines above — was larger. It compared 1,398 people ages 20 to 60 who had lymphoma with 4,193 people who did not have lymphoma but who were otherwise similar. The study found that

• lymphoma was 21% more common among those with tattoos
• lymphoma risk varied depending on how much time had passed since getting the tattoo:
  • within two years, lymphoma risk was 81% higher
  • between three and 10 years, no definite increased lymphoma risk was detected
  • 11 or more years after getting a tattoo, lymphoma risk was 19%

There was no correlation between the size or number of tattoos and lymphoma risk.

What else should you know about the study?

Importantly, nearly all of the differences in rates of lymphoma between people with and without tattoos were not statistically significant. That means the reported link between lymphoma and tattoos is questionable — and quite possibly observed by chance. In fact, some of the other findings argue against a connection, such as the lack of a link between size or number of tattoos and lymphoma risk.

In addition, if tattoos significantly increase a person's risk of developing lymphoma, we might expect lymphoma rates in the US to be rising along with the popularity of tattoos. Yet that's not the case.

Finally, a study like this one (called an association study) cannot prove that a potential trigger of disease (in this case, tattoos) actually caused the disease (lymphoma). There may be other factors (called confounders) that are more common among people who have tattoos, and those factors might account for the higher lymphoma risk.

Do tattoos come with other health risks?

While complication rates from reputable and appropriately certified tattooists are low, there are health risks associated with tattoos:

• infection, including bacterial skin infections or viral hepatitis
• allergic reactions to the ink
• scarring
• rarely, skin cancer (melanoma and other types of skin cancer).

The bottom line

Despite headlines suggesting a link between tattoos and the risk of lymphoma, there's no convincing evidence it's true. We'll need significantly more research to say much more than that. In the meantime, there are more important health concerns to worry about and much better ways for all of us to reduce cancer risk.

Abnormal results on a prostate-specific antigen (PSA) screening test for cancer are typically followed by a systematic biopsy. During that procedure, doctors use a long needle to extract roughly a dozen samples from the prostate while looking at the gland on an ultrasound machine. Those samples can then be checked for cancer under a microscope.

Limitations and concerns

But systematic biopsies can be problematic. A major concern is that they overdiagnose low-grade, slow-growing tumors that might never become life-threatening, thereby leading to unnecessary treatments.

Researchers are seeking alternatives to the systematic biopsy in men flagged by PSA screening. One option is to start with a magnetic resonance imaging (MRI) scan of the prostate, and then focus the biopsy only on areas that look suspicious for cancer. This is called an MRI-targeted biopsy, and it’s becoming increasingly common.

Could an MRI miss early-stage cancer that later turns out to be incurable? This is an outstanding worry, especially since systematic biopsies sometimes find newly-forming cancer that MRIs aren’t yet able to detect. Indeed, systematic and targeted biopsies are often given together to boost the odds of finding clinically significant disease that may need immediate treatment.

Methodology

Now, a large Swedish study provides encouraging evidence favoring the MRI-only approach.

The team invited 38,316 men ranging from 50 to 60 years in age to undergo PSA screening. If a man’s PSA level was 3.0 nanograms per milliliter (ng/mL) or higher, then he was enrolled into the study. The investigators wound up with 13,153 men who were randomly distributed between two groups:

• Systematic biopsy group: All the men in this group got a systematic biopsy plus an MRI. If a man’s MRI was positive for suspicious lesions, then he also got a targeted biopsy.
• MRI-targeted biopsy group: All of the men in this group got an MRI, but none got a systematic biopsy. Men with suspicious lesions on MRI got a targeted biopsy.

This initial screening round was followed by repeat screening rounds — all following the same protocols — at two-, four-, and eight-year-intervals.

What the study showed

After a median follow-up of 3.9 years (starting from and including the first screening round), prostate cancer had been detected in 185 men from the MRI-targeted group and 298 men from the systematic biopsy group. Systematic biopsies generated more clinically insignificant cancer diagnoses — 159 compared to 68 in the MRI-targeted group. During the first screening round, “The risk of such a diagnosis was 51% lower in the MRI-targeted biopsy group than the systematic biopsy group,” the authors wrote.

The authors emphasized that omitting biopsies in patients with MRI-negative results cut diagnoses of clinically insignificant cancer, meaning cancer that is slow-growing and may never need treatment, by more than half. “And importantly, the associated risk of detecting clinically significant cancer during follow-up and at later screening visits was very low in both groups,” said Dr. Jonas Hugosson, chief urologist at the University of Gothenberg and the study’s first author. “A total of 14 such cases (0.2 % of men who participated) were diagnosed in the systematic biopsy group and eight (0.1 %) in the MRI-targeted biopsy group.”

Commentary from experts

“This study provides encouraging — though very early — data that supports the increasing use of MRI as the first diagnostic modality, following evaluation of an abnormal PSA value,” said Dr. Marc Garnick, the Gorman Brothers Professor of Medicine at Harvard Medical School and Beth Israel Deaconess Medical Center, and editor-in-chief of the Harvard Medical School Guide to Prostate Diseases. “The practice of not automatically going to prostate needle biopsy when an abnormal PSA is detected has gained in popularity in Europe, and this study may help increase its usefulness in the United States.”

“While these results are encouraging, the decision to omit biopsy in men with a negative MRI must be individualized based on the risk of detecting prostate cancer,” added Dr. Boris Gershman, a urologist at Beth Israel Deaconess Medical Center and an assistant professor at Harvard Medical School focusing on prostate and bladder cancer. “For example, biopsy may still be considered in men with markedly elevated PSA, even if the prostate MRI does not identify any lesions.”

Over the course of a lifetime, as many as seven in 10 adults in the United States will directly experience or witness harrowing events. These include gun violence, car accidents, and other personal trauma; natural or human-made disasters, such as Hurricane Katrina and the 9/11 terrorist attacks; and military combat. And some — though not all — will experience post-traumatic stress disorder, or PTSD.

New guidelines released in 2024 can help guide effective treatment.

What is PTSD?

PTSD is a potentially debilitating mental health condition. It’s marked by recurrent, frightening episodes during which a person relives a traumatic event.

After a disturbing event, it’s normal to have upsetting memories, feel on edge, and have trouble sleeping. For most people, these symptoms fade over time. But when certain symptoms persist for more than a month, a person may be experiencing PTSD.

These symptoms include

• recurring nightmares or intrusive thoughts about the event
• feeling emotionally numb and disconnected
• withdrawing from people and certain situations
• being jumpy and on guard.

The National Center for PTSD offers a brief self-screening test online, which can help you decide whether to seek more information and help.

Who is more likely to experience PTSD?

Not everyone who experiences violence, disasters, and other upsetting events goes on to develop PTSD. However, military personnel exposed to combat in a war zone are especially vulnerable. About 11% to 20% of veterans who served in Iraq or Afghanistan have PTSD, according to the National Center for PTSD.

What about people who were not in the military? Within the general population, estimates suggest PTSD occurs in 4% of men and 8% of women — a difference at least partly related to the fact that women are more likely to experience sexual assault.

What are the new guidelines for PTSD treatment?

Experts from the U.S. Department of Veterans Affairs and Department of Defense collaborated on new guidelines for treating PTSD. They detailed the evidence both for and against specific therapies for PTSD.

Their findings apply to civilian and military personnel alike, says Dr. Sofia Matta, a psychiatrist at Harvard-affiliated Massachusetts General Hospital and senior director of medical services at Home Base, a nonprofit organization that provides care for veterans, service members, and their families.

The circle of care is widely drawn for good reason. “It’s important to recognize that PTSD doesn’t just affect the person who is suffering but also their families and sometimes, their entire community,” Dr. Matta says. The rise in mass shootings in public places and the aftermath of these events are a grim reminder of this reality, she adds.

Which treatment approaches are most effective for PTSD?

The new guidelines looked at psychotherapy, medications, nondrug therapies. Psychotherapy, sometimes paired with certain medicines, emerged as the most effective approach.

The experts also recommended not taking certain drugs due to lack of evidence or possible harm.

Which psychotherapies are recommended for PTSD?

The recommended treatment for PTSD, psychotherapy, is more effective than medication. It also has fewer adverse side effects and people prefer it, according to the guidelines.

Which type of psychotherapy can help? Importantly, the most effective therapies for people with PTSD differ from those for people with other mental health issues, says Dr. Matta.

Both cognitive processing therapy and prolonged exposure therapy were effective. These two therapies teach people how to evaluate and reframe the upsetting thoughts stemming from the traumatic experience. The guidelines also recommend mindfulness-based stress reduction, an eight-week program that includes meditation, body scanning, and simple yoga stretches.

Which medications are recommended for PTSD?

Some people with severe symptoms need medication to feel well enough to participate in therapy. “People with PTSD often don’t sleep well due to insomnia and nightmares, and the resulting fatigue makes it hard to pay attention and concentrate,” says Dr. Matta.

Three medicines commonly prescribed for depression and anxiety — paroxetine (Paxil), sertraline (Zoloft), and venlafaxine (Effexor) — are recommended. Prazosin (Minipress) may help people with nightmares, but the evidence is weak.

Which medications are not recommended for PTSD?

The guidelines strongly recommended not taking benzodiazepines (anti-anxiety drugs often taken for sleep). Benzodiazepines such as alprazolam (Xanax) and clonazepam (Klonopin) offer no proven benefits for people with PTSD. They have several potential harms, including negative cognitive changes and decreased effectiveness of PTSD psychotherapies.

What about cannabis, psychedelics, and brain stimulation therapies?

Right now, evidence doesn’t support the idea that cannabis helps ease PTSD symptoms. And there are possible serious side effects from the drug, such as cannabis hyperemesis syndrome (severe vomiting related to long-term cannabis use).

There isn’t enough evidence to recommend for or against psychedelic-assisted therapies such as psilocybin (magic mushrooms) and MDMA (ecstasy). “Because these potential therapies are illegal under federal law, the barriers for conducting research on them are very high,” says Dr. Matta. However, recent legislative reforms may make such studies more feasible.

Likewise, the evidence is mixed for a wide range of other nondrug therapies, such as brain stimulation therapies like repetitive transcranial magnetic stimulation or transcranial direct current stimulation.

For neuroscientist Sara Lazar, a form of meditation called open awareness is as fundamental to her day as breathing.

“I just become aware that I am aware, with no particular thing that I focus on,” explains Lazar, an associate researcher in the psychiatry department at Massachusetts General Hospital and assistant professor of psychology at Harvard Medical School. “This sort of practice helps me become more aware of the subtle thoughts and emotions that briefly flit by, that we usually ignore but are quite useful to tune into.”

But meditation doesn’t just change your perspective in the moment. Some studies show certain types of meditation offer an array of benefits, from easing chronic pain and stress and lowering high blood pressure to help relieve anxiety and depression. And, as Lazar’s research has shown, meditation can actually change the structure and connectivity of brain areas that help us cope with fear and anxiety.

“It’s become really clear that all of our experiences shape our brain in one way or another,” Lazar says. “A lot of people talk about meditation being a mental exercise. Just as you build your physical muscles, you can build your calm muscles. Meditation is a very effective way of training those muscles.”

What counts as meditation?

More than you might have believed. An intriguing if somewhat perplexing aspect of meditation is that it encompasses a broad range of practices. “It’s clear what is not meditation, but there’s less consensus on what it is,” Lazar says.

Open awareness, Lazar’s go-to meditation, joins other forms, including focused awareness, slow deep breathing, guided meditation, and mantra meditation, along with many variations. At their core, Lazar says, is an awareness of the moment, noticing what you’re experiencing and nonjudgmentally disengaging from intrusive thoughts that might interfere with your ability to attend to this task.

Meditation can also involve sitting with eyes closed and paying attention to your body and any sensations that are present. A regular meditation practice typically involves slowing down, breathing, and observing inner experience.

“Meditation can involve flickering candles, breath awareness, or mantras — all of these things,” Lazar says. “But there’s definitely an element of focusing and regulating your attention.”

A close look at how meditation alters the brain

Small MRI imaging studies have zeroed in meditation’s effects on the amygdala, an almond-shaped structure deep within the brain that processes fear and anxiety as well as other emotions.

Lazar and her colleagues have spent many years laying the groundwork to show how practicing mindfulness-based stress reduction (MBSR) alters the amygdala after only about two months. The MBSR practice in this research consisted of weekly group meetings and daily home mindfulness practices, including sitting meditation and yoga.

What has their research found?

One key study involved 26 people with high levels of perceived stress. After an eight-week regimen of MBSR, brain scans showed the density of their amygdalae decreased, and these brain changes correlated to lower reported stress levels.

Building on this, Lazar and colleagues designed a study that focused on 26 people diagnosed with generalized anxiety, a disorder marked by excessive, ongoing, and often illogical anxiety levels. The researchers randomized participants to either practice MBSR or receive stress management education. These participants were compared to 26 healthy participants.

In this first-of-its-kind research, participants were shown a series of images with angry or neutral facial expressions while their brain activity was gauged using functional MRI imaging. At the beginning of the study, anxiety patients showed higher levels of amygdala activation in response to neutral faces than healthy participants. This suggests a stronger fear response to a nonthreatening situation.

But after eight weeks of MBSR, MRI imaging showed increased connections between the amygdala and the prefrontal cortex, a brain area crucial to emotional regulation. The amygdalae in participants with generalized anxiety no longer displayed a fear response to neutral faces. These participants also reported their symptoms had improved.

“It seems meditation helps to down-regulate the amygdala in response to things it perceives to be threatening,” Lazar says.

How can meditation benefits help us in daily life?

Lazar believes training your brain to stop and notice your thoughts in a slightly detached way can calm you amidst the muddle of work deadlines, family friction, or distressing news.

“That’s one of the biggest translations” of meditation to everyday benefits, she says. “The person or situation that is stressing you out won’t go away, but you can watch your reactivity to the situation in a mindful, detached way, which shifts your relationship to it.”

“It’s not indifference,” she adds. “It’s sort of like a bubble bursting — you realize you don’t need to keep going on this loop. Once you see that, it totally shifts your relationship to that reaction bubbling through your brain.”

Want to try meditation — or expand your practice?

Haven’t tried meditating? To get started, Lazar recommends the Three-Minute Breathing Space Meditation. This offers a quick taste of meditation, walking you through three pared-down but distinct steps. “It’s simple, fast, and anyone can do it,” she says.

Simple ways to expand this basic approach are:

• adding minutes, just as you might for exercise
• meditating outdoors
• pausing to notice how you feel after you meditate.

“Or try either doing a longer session or short hits throughout the day, such as a three-minute breathing break four to five times a day,” Lazar suggests.

Another way to enhance your practice is to use ordinary, repetitive moments throughout the day — such as reaching for a doorknob — as a cue to pause for five seconds and notice the sensation of your hand on the knob.

“As you walk from your office to your car, for instance, instead of thinking of all the things you have to do, you can be mindful while you’re walking,” Lazar says. “Feel the sunshine and the pavement under your feet. There are simple ways to work meditation into each day.”

It’s an unfortunate reality: all medicines can cause side effects. While there are a few tried-and-true ways to deal with drug side effects, here’s a less common option to consider: adding a second medication.

That’s the approach taken with valbenazine (Ingrezza), a drug approved for a condition called tardive dyskinesia that’s caused by certain medicines, most of which are for mental health. Let’s dive into what TD is, how this drug is advertised, and what else to consider if a medicine you take causes TD.

What is tardive dyskinesia?

Tardive dyskinesia (TD) is a condition marked by involuntary movements of the face or limbs, such as rapid eye blinking, grimacing, or pushing out the tongue. TD is caused by long-term use of certain drugs, many of which treat psychosis.

TD may be irreversible. Early recognition is key to improvement and preventing symptoms from getting worse. If you take antipsychotic medicines or other drugs that can cause TD, tell your prescribing health care provider right away about any worrisome symptoms.

A sidewalk sale, a cookout in the park, and a pitch

One ad for Ingrezza starts with a young man working with customers at a sidewalk sale. Though his mental health is much better, he says, now he’s suffering with TD, a condition “that can be caused by some mental health meds.” A spotlight shines on his hands as he fumbles and drops an instant camera he’s selling. He seems embarrassed and his customers look perplexed.

Next we see a young woman at a cookout in a park. The mysterious spotlight is trained on her face as she blinks and grimaces involuntarily. Her voiceover explains that she feels like her involuntary movements are “always in the spotlight.”

Later these two happily interact with others, their movement problems much improved. A voiceover tells us Ingrezza is the #1 treatment for adults with TD. The dose — “always one pill, once a day” — can improve unwanted movements in seven out of 10 people. And people taking Ingrezza can stay on most mental health meds.

That’s the pitch. The downsides come next.

What are the side effects of this drug to control a side effect?

As required by the FDA, the ad lists common and serious side effects of Ingrezza, including

• sleepiness (the most common side effect)
• depression, suicidal thoughts, or actions
• heart rhythm problems
• allergic reactions, which can be life-threatening
• fevers, stiff muscles, or problems thinking, which may be life threatening
• abnormal movements.

That’s right, one possible side effect is abnormal movements — a symptom this drug is supposed to treat!

What the ad gets right

The ad

• appropriately highlights TD as a troubling yet treatable condition that can cause stress and embarrassment and affect a person’s ability to function
• emphasizes once-daily dosing, presumably because the recommended frequency of a competitor’s drug for TD is twice daily
• shares clinical studies that support effectiveness claims
• covers many of the most common and serious side effects.

What else should you know?

Unfortunately, the ad skims over — or entirely skips — some important details. Below are a few examples.

Which medicines cause TD?

We never learn which medicines can cause TD (especially when used long-term), which seems vital to know. Many, but not all, are used to help treat certain mental health disorders, such as schizophrenia or bipolar disorder. Here are some of the most common.

Mental health medicines:

• haloperidol (Haldol)
• fluphenazine (Prolixin)
• risperidone (Risperdal)
• olanzapine (Zyprexa).

Other types of medicines:

• metoclopramide (Reglan), which may be prescribed for nausea, hiccups, and a stomach problem called gastroparesis
• prochlorperazine (Compazine, Compro), most often prescribed for severe nausea, migraine headaches, or vertigo.

Also, the ad never explains that TD may be irreversible regardless of treatment. Because improvement is most likely if caught early, it’s important for people taking these medicines to check in with their health provider if they notice TD symptoms described above — especially if symptoms are growing worse.

What about effectiveness and cost?

Seven in 10 people reported that their symptoms improved, according to the ad. How much improvement? That wasn’t shared. But here’s what I found in a key study:

• Among 202 study participants with TD, only 24% reported having minimal or no symptoms of TD after six weeks of treatment with Ingrezza.
• Up to 67% of study subjects reported smaller improvements in symptoms.

What happens after six weeks? A few small follow-up studies suggest that some people who continue taking Ingrezza may improve further over time.

And the cost? That’s also never mentioned in the ad. It’s about $8,700 a month. No details on the financial assistance program, or who qualifies for free treatment, are provided.

Are there other ways to manage TD?

Well, yes. But the ad doesn’t mention those either. Three approaches to discuss with your healthcare provider are:

• Avoid drugs known to cause TD when other options are available.
• If you need to take these medicines, it’s safest to use the lowest effective dose for the shortest time possible. For example, limiting metoclopramide to less than three months lowers risk for TD.
• If you notice TD symptoms, ask about lowering the dose or stopping the offending drug right away. This may successfully reverse, or reduce, the symptoms.

If you have TD, you and your health care provider can consider several options:

• whether other drug treatments for TD not mentioned in the ad, such as deutetrabenazine (Austedo) or tetrabenazine (Xenazine), might cost less or minimize bothersome side effects
• botulinum toxin injections (Botox), which can relax the muscle contractions causing involuntary movements
• deep brain stimulation, which involves electrical stimulation to certain areas of the brain to interrupt nerve signals to abnormally contracting muscles.

The bottom line

The idea of treating a drug’s side effect with another drug may not be appealing. Certainly, it makes sense to try other options first.

But sometimes there are no better options. It’s always worth asking whether a treatment is worse than the disease. But TD is one situation in which all options — including a drug treatment for another drug’s side effects — are well worth considering.
