Parents like to think that they know what is going on with their children — and that they would know if their teen was suicidal. However, research shows that this is not always the case.

Teens may consider suicide more often than parents realize

In a study published a few years ago in the journal Pediatrics, researchers interviewed more than 5,000 adolescents ages 11 to 17. In those interviews, they asked them if they had ever thought about killing themselves — or if they had ever thought a lot about death or dying. The teens' parents were asked if they believed that their teens had ever thought about killing themselves, or had thought a lot about death or dying.

There wasn’t a whole lot of match-up. Half of the parents of the adolescents who thought of killing themselves were unaware — as were three-quarters of the parents of adolescents who thought often about death.

This disconnect looms larger as research shows mental health problems are on the rise in youth. According to the 2021 Youth Risk Behavioral Survey, 42% of high school students reported persistent feelings of sadness and hopelessness; 22% seriously considered suicide, and 10% attempted it.

The numbers were higher for girls and youth who identify as LGBTQ+:

• Almost 60% of girls experienced persistent sadness and hopelessness; 30% seriously considered attempting suicide, and 13% attempted it.
• Among LGBTQ+ youth, 70% experienced persistent sadness and hopelessness; 45% seriously considered attempting suicide, and 22% attempted it.

Many factors contribute to this. Stress and isolation caused by the pandemic clearly played a role. While teens are back in school, re-entry has been difficult for many. Social media clearly plays a role, inviting unrealistic comparisons, reinforcing negative thoughts and ideas, and encouraging doomscrolling. It is also a source of bullying: in the report, 16% of high school students reported being bullied electronically, including 20% of girls and 27% of those who identify as LGBTQ+.

Why the disconnect between teens and parents?

It’s not that surprising that parents don’t always know that their teens are considering suicide. Teens may not always realize how bad they are feeling, and may not want to tell their parents when they do — both for fear of worrying them, and also because of uncertainty about how their parents might react.

Parents may miss signs of depression in their teens, or quite genuinely misinterpret them or attribute them to something innocent; after all, it’s natural to want to believe that your child is fine, rather than thinking that they might be suicidal. And given how much drama can be intrinsic to the life of a teen, it’s understandable that parents could misinterpret statements about death or dying as, well, just teen drama.

What can parents do?

• Be aware of signs of depression in teens, and never ignore them. Acting sad is one of them, but there are many others:
  • dropping grades
  • being irritable or angry often
  • acting bored all the time, and/or dropping out of activities
  • difficulty with relationships, including changing peer groups or becoming more isolated
  • dangerous or risky behavior
  • persistent physical complaints such as headaches or stomachaches
  • fatigue.
• Listen to your teen, and never assume that statements like “nobody cares if I live or die” are just drama. Instead of saying, “You don’t mean that,” ask them if they do mean it. Often parents worry that asking about suicide might “give them ideas,” but asking may be the only way to know — and the best way to show your teen that you are taking them seriously.
• Learn how to have tough conversations about mental health and suicide. The American Academy of Pediatrics has many tips and resources for parents.
• Get help. Call your doctor, call a mental health professional, call the new nationwide number 988 that can link you to local help like a suicide hotline, or take your child to a local emergency room. This is crucial. If counseling is recommended, do your best to schedule it, letting your doctor know if you are having trouble finding a provider. Make sure your teen sticks with it.
• If you suspect your teen may be depressed or suicidal, take precautions. If you have a gun in your house, make sure it is locked up with the ammunition locked separately. Take stock of prescription medications and alcohol in your house that could be used for self-harm, and either get rid of them or be sure they are stored safely.

Sometimes it is just drama — or short-term blues after a breakup or another one of life’s inevitable disappointments. And in the study, half of the teens whose parents thought they were suicidal, and two-thirds of those whose parents believed their teens thought about death, said they were fine. But when it comes to suicide, it’s always better to be safe than sorry. So ask the questions — and ask for help.

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.

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.

Want your child to grow up healthy, happy, smart, capable, and resilient? Play with them. Infants and toddlers thrive on playful games that change as they grow.

Why does play matter during the first few years of life?

More than a million new nerve connections are made in the brain in the first few years of life. And pruning of these neural connections makes them more efficient. These processes literally build the brain and help guide how it functions for the rest of that child’s life. While biology — particularly genetics — affects this, so does a child’s environment and experiences.

Babies and children thrive with responsive caregiving. Serve and return, a term used by the Harvard Center on the Developing Child, describes this well: back-and-forth interactions, in which the child and caregiver react to and interact with each other in a loving, nurturing way, are the building blocks of a healthy brain and a happy child, who will have a better chance of growing into a healthy, happy, competent, and successful adult.

Play is one of the best ways to do responsive caregiving. To maximize the benefits of play:

• Bring your full attention. Put the phone down, don’t multitask.
• Be reciprocal. That’s the “serve and return” part. Even little babies can interact with their caregivers, and that’s what you want to encourage. It doesn’t have to be reciprocal in an equal way — you might be talking in sentences while your baby is just smiling or cooing — but the idea is to build responsiveness into the play.
• Be attuned to developmental stages. That way your child can fully engage — and you can encourage their development as well.

Great games to play with infants: 6 to 9 months

The Center for the Developing Child has some great ideas and handouts for parents about specific games to play with their children at different ages.

6-month-olds and 9-month-olds are learning imitation and other building blocks of language. They are also starting to learn movement and explore the world around them.

Here are some play ideas for this age group:

• Play peek-a-boo or patty-cake.
• Play games of hiding toys under a blanket or another toy, and then “find” them, or let the baby find them.
• Have back-and-forth conversations. The baby’s contribution might just be a “ma” or “ba” sound. You can make the same sound back, or pretend that your baby is saying something (“You don’t say! Really? Tell me more!”).
• Play imitation games: if your baby sticks out their tongue, you do it too, for example. Older babies will start to be able to imitate things like clapping or banging, and love when grownups do that with them.
• Sing songs that involve movement, like “Itsy Bitsy Spider” or “Trot, Trot to Boston” with words and motions.
• Play simple games with objects, like putting toys into a bucket and taking them out, or dropping them and saying “boom!”

Great games to play with toddlers

Between 12 months and 18 months, young toddlers are gaining more language and movement skills, and love to imitate. You can:

• Play with blocks, building simple things and knocking them down together.
• Do imaginative play with dolls or stuffed animals, or pretend phone calls.
• Use pillows and blankets to build little forts and places to climb and play.
• Play some rudimentary hide-and-seek, like hiding yourself under a blanket next to the baby.
• Continue singing songs that involve movement and interaction, like “If You’re Happy And You Know It.”
• Go on outings and explore the world together. Even just going to the grocery store can be an adventure for a baby. Narrate everything. Don’t worry about using words your baby doesn’t understand; eventually they will, and hearing lots of different words is good for them.

Older toddlers, who are 2 or 3 years old, are able to do more complicated versions of these games. They can do matching, sorting, and counting games, as well as imitation and movement games like “follow the leader” (you can get quite creative and silly with that one).

As much as you can, give yourself over to play and have fun. Work and chores can wait, or you can actually involve young children in chores, making that more fun for both of you. Checking social media can definitely wait.

Playing with your child is an investment in your child’s future — and a great way to build your relationship and make both of you happy.

Loneliness is complicated. You can feel lonely when you lack friends and miss companionship, or when you’re surrounded by people — even friends and family.

Either way, loneliness can have devastating health effects. It boosts risk for coronary artery disease, stroke, depression, high blood pressure, declining thinking skills, inability to perform daily living tasks, and even an early death. The remedy? Below we offer three ways to ease loneliness and add happiness by helping you expand your social network.

Taking the first steps

Not all loneliness can be solved by seeking out people. Loneliness that occurs despite relationships may require talk therapy and a journey that looks inward.

Reducing loneliness caused by a lack of relationships is more of an outward journey to make new friends. “That’s a challenge as we get older, because people are often established in their social groups and aren’t as available as they might have been in a different phase of life. So you have to be more entrepreneurial and work harder to make friends than you once did,” says Dr. Jacqueline Olds, a psychiatrist at Harvard-affiliated McLean Hospital and the coauthor of two books on loneliness.

Trying these strategies can help.

1. Seek like-minded souls

Being around people who share your interests gives you a head start on making friends: you already have something in common.

Start by considering your interests. Are you a voracious reader, a history lover, a movie aficionado, a gardener, a foodie, a puppy parent, or an athlete? Are you passionate about a cause, your community, or your heritage? Do you collect things? Do you love classic cars? Do you enjoy sprucing up old furniture? Maybe you want to learn something new, like how to cook Chinese food or speak another language. Search for online groups, in-person clubs, volunteer opportunities, or classes that match any of your interests or things you’d like to try.

Once you join a group, you’ll need to take part in it regularly to build bonds. If you can gather in person, it’s even better. “The part of our brain involved in social connection is stimulated by all five senses. When you’re with someone in the same room, you get a much stronger set of stimuli than you do by watching them on an electronic screen,” Dr. Olds says.

2. Create opportunities

If joining someone else’s group is unappealing, start your own. Host gatherings at your place or elsewhere. “All it takes is three people. You can say, ‘Let’s read books or talk about a TV show or have a dinner group on a regular basis,’” Dr. Olds says.

Other ideas for gatherings — either weekly or monthly — include:

• game nights
• trivia nights
• hikes in interesting parks
• beach walks
• bird-watching expeditions
• running or cycling
• meditation
• museum visits
• cooking
• knitting, sewing, or crafting
• shopping
• day trips to nearby towns
• jewelry making
• collector show-and-tell (comic books, antique dolls, baseball cards).

The people you invite don’t have to be dear friends; they can just be people you’d like to get to know better — perhaps neighbors or work acquaintances.

If they’re interested in a regular gathering, pin down dates and times. Otherwise, the idea might stay stuck in the talking stages. “Don’t be timid. Say, ‘Let’s get our calendars out and get this scheduled,’” Dr. Olds says.

3. Brush up your social skills

Sometimes we’re rusty in surface social graces that help build deeper connections. “It makes a huge difference when you can be enthusiastic rather than just sitting there and hoping someone will realize how interesting you are,” Dr. Olds says.

Tips to practice:

• Smile more. Smiling is welcoming, inviting, and hospitable to others.
• Be engaging. Prepare a few topics to talk about or questions to ask — perhaps about the news or the reason you’ve gathered (if it’s a seminar, for example, ask how long someone has been interested in the subject). Or look for a conversation starter. “Maybe the person is wearing a pretty brooch. Ask if there’s a story behind it,” Dr. Olds suggests.
• Be a good listener. “Listen in a way that someone realizes you’re paying attention. Hold their gaze, nod your head or say ‘Mm hmm’ as they’re talking so you give feedback. Assume everyone in the world is just yearning for your feedback,” Dr. Olds says.
• Ask follow-up questions. Don’t ignore signals that someone has interesting stories to tell. “If they allude to something, your job is to look fascinated and ask if they can tell you more. They’re dropping crumbs on a path to a deeper exchange,” Dr. Olds notes.

Even chats that don’t lead to friendships can be enriching. A 2022 study found that people who had the most diverse portfolios of social interactions — exchanges with strangers, acquaintances, friends, or family members — were much happier than those with the least diverse social portfolios.

Ultimately, a wide variety of interactions contributes to well-being, whether you’re talking to the cashier at the supermarket, a neighbor, an old friend, or a new one. And all of these connections combined may go a long way toward helping you feel less lonely.

Ketamine is an unusual type of psychedelic drug — called a dissociative — that is undergoing a resurgence in popularity. Originally derived from PCP, or “angel dust,” ketamine has been used in hospitals and veterinary clinics as an anesthetic for decades, and has been cited as a drug of misuse under the moniker “special K.”

It is the effects that ketamine reliably produces that underlie both its medical and recreational uses: pain control, forgetfulness, intoxication, disassociation, and euphoria. Recently, it has been used more widely due to its approval for treatment-resistant depression (TRD) — that is, severe depression that has not improved via other therapies, including people who are experiencing suicidal thoughts.

Evidence of the benefit of ketamine

A prescription version of ketamine called esketamine (Spravato), given through a nasal spray, was approved in 2019 by the FDA for TRD; however, according to the guidelines, it is only to be used “under the supervision of a health care provider in a certified doctor’s office or clinic.” That means medical professionals need to watch you use it, and then follow you after you’ve taken your dose, checking your vital signs and how you are doing clinically.

The effectiveness of ketamine for TRD was first demonstrated for short-term treatment in research that resulted in clinically and statistically significant decreases in depression scores for ketamine versus placebo (In both groups in this study, the patients continued with their regular antidepressants because of concern of not treating TRD in the placebo arm.) Nasal ketamine was shown to have longer-term efficacy, in a study where ketamine (plus the regular antidepressant) helped people stay in stable remission 16 weeks into treatment.

Relief from TRD with ketamine happens rapidly. Instead of waiting for an SSRI to hopefully provide some relief over the course of weeks, people who are suffering under the crushing weight of depression can start to feel the benefits of ketamine within about 40 minutes.

Is ketamine the right treatment for you?

This is a discussion that should include your primary care doctor, your mental health provider, and any other health care professionals who care for you. It’s important to remember that ketamine isn’t a first-option treatment for depression, and it is generally used only when other, more longstanding treatments haven’t been effective. It is not thought to be curative; rather, it improves symptoms for a certain amount of time. It is easier to say who isn’t appropriate for ketamine treatment, based on the side effects.

Should you go to a ketamine clinic for treatment?

Independent, outpatient ketamine clinics are popping up all over the place. It is estimated that there are currently hundreds to thousands of these clinics — almost all of which were established in 2019 when ketamine was approved for TRD. Typically, these clinics are for-profit enterprises that are staffed by some combination of either a psychiatrist or an anesthesiologist (who can administer the infusion), a nurse, a social worker, and (of course) the businesspeople who make it all work.

In writing this piece, I called several ketamine clinics, posing as a patient, to investigate what would be involved in receiving ketamine therapy. Most of them seemed as if they would provide ketamine for me without any major hurdles, after an introductory medical interview by a nurse or a social worker. A few clinics required communication or a diagnosis from my psychiatrist — and this seemed quite sensible.

The clinics operate on a fee-for-service arrangement, so you would pay out of pocket, as insurance rarely covers this treatment. In the Boston area where I live, the ketamine infusions cost about $600 each, and a course of six infusions and a clinical re-evaluation are typically recommended. (I should note that the ketamine clinics affiliated with medical academic institutions seem to have more safeguards in place, and they may also be enrolling people in clinical trials.)

Are ketamine clinics safe?

These ketamine clinics raise many questions — namely, what does one look for in a reputable and safe ketamine clinic? Currently, we don’t yet have definitive answers to that question. One wonders if a ketamine infusion, which can cause a profound dissociation from reality, would be better controlled in a hospital setting, where there are protocols for safety in case anything goes wrong. It was unclear (in part because I didn’t actually go through with the therapy) how much communication, if any, there would be between the ketamine clinic staff and your health care providers, and typically the treatments you receive would not be included in your primary electronic medical record.

What are the side effects?

Ketamine is generally considered safe, including for those who are experiencing suicidal ideation (thoughts or plans for suicide). The main side effects are dissociation, intoxication, sedation, high blood pressure, dizziness, headache, blurred vision, anxiety, nausea, and vomiting. Ketamine is avoided or used with extreme caution in the following groups:

• people with a history of psychosis or schizophrenia, as there is concern that the dissociation ketamine produces can make psychotic disorders worse
• people with a history of substance use disorder, because ketamine can cause euphoria (likely by triggering the opioid receptors) and some people can become addicted to it (which is called ketamine use disorder)
• teenagers, as there are some concerns about the long-term effects of ketamine on the still-developing adolescent brain
• people who are pregnant or breastfeeding
• older adults who have symptoms of dementia.

More detailed research needs to be done on the longer-term benefits and side effects of ketamine treatment, and on its safety and effectiveness for teens and older adults, as well as for the emerging indications of ketamine therapy for PTSD, OCD, alcohol use disorder, and other mental health conditions.

Finally, there is some concern that, with repeated dosing, ketamine can start to lose its effectiveness and require larger doses to produce the same effect, which is not sustainable.

Ketamine could provide hope for people with serious depression

Serious, treatment-resistant depression can rob people of hope for the future and hope that they will ever feel better. Ketamine can provide help and hope to patients who have not found relief with any other treatments. Given its efficacy in people considering suicide, it is plausible that ketamine may be lifesaving.

As we learn more from research on ketamine and from people’s experiences in newer clinics, we will be better able to answer the questions of ketamine’s longer-term effectiveness and what safeguards are needed for treatment. We may also learn who is most likely to safely benefit from ketamine therapies, and the best method of administration: intravenous infusion, a nasal spray, or a pill.

A visit with a surgeon can be overwhelming. You may feel anxious about your planned surgery. Many questions could be swirling in your head during a rushed visit. While surgeons have a reputation as technical specialists, bedside manner may be lacking at times.

It sounds simple, but setting the right expectations — on both sides — can ease your anxiety and help you feel more comfortable during a visit with your surgeon. So what exactly does this mean? And how can you accomplish it?

Tell your story

Tell your story to help set clear goals. Beyond simply stating what hurts or what is not working, be sure to include details such as

• how your current condition limits what you enjoy doing
• your daily activities
• how your condition affects your relationship with your social circle and family
• upcoming plans or goals such as travel, or life events like vacations or weddings.

Sharing details like these helps you collaborate to define a successful outcome for surgery.

Listen with your goals in mind

When explaining surgical options, surgeons are obligated to discuss key information, including risks, potential complications, and likely outcomes. Encourage your surgeon to put these facts into context based on what is important to you.

• Ask questions about how surgery will affect things you enjoy doing, such as playing pickleball, taking walks, cooking, reading, or listening to music.
• Ask what you should realistically expect during recovery and once you have recovered. For example, if you have a vacation or travel planned, be sure to discuss how surgery will affect your plans.

Define success before your surgery

Once you are confident that you have told your story and feel like you and your surgeon have set appropriate expectations, take the next step. Ask whether this discussion affects your surgeon’s approach to surgery, and explore how you each define surgical success.

Often, both surgeon and patient agree on a definition of success: for example, remove the entire tumor. But this simple definition may leave room for misalignment. Let’s say a surgeon is able to entirely remove a thyroid tumor, but now the patient speaks in a hoarse voice. While technically successful, this surgery may feel like a failure unless the person understood and accepted the risk that it could affect how they speak.

This highlights the importance of setting expectations. In this example, clear speech after surgery might be your expectation as a patient. Your surgeon must balance explaining how surgical risks might affect that expectation with the reality of treating the condition. Surgery is more likely to feel successful if both sides discuss and align their expectations.

Give yourself time when possible

Processing information about surgery can take time. A surgeon may have to provide realistic expectations that do not align with your initial expectations and hopes.

Some surgeries are urgent, others are not. If you do not need to make an immediate decision, be open with your surgeon. Let them know that you need time to consider the surgeon’s definition of success and your own. Reflecting on the discussion can reduce the stress and anxiety you’re likely to feel during an initial visit.

The bottom line: Making the most of your appointment

Communication goes two ways during a good pre-surgery visit. Do your best to tell your story and emphasize details of your life that are important. When listening, ensure that your surgeon acknowledges these details and describes how surgery may affect your life, as opposed to simply stating technical facts about the surgery.

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.

Hot flashes and sleep or mood changes are well-known, troublesome symptoms that may occur during perimenopause and menopause. Now, one survey suggests nearly 80% of midlife women use cannabis to ease certain symptoms, such as mood issues and trouble sleeping.

Mounting numbers of US states have legalized marijuana for medical or recreational use in recent years. This wave of acceptance runs alongside skepticism in some quarters concerning FDA-approved menopause treatment options, including hormone therapy. But a lack of long-term research data surrounding cannabis use has led one Harvard expert to question how safe it may be, even while acknowledging its likely effectiveness for certain menopause woes.

“More and more patients tell me every year that they’ve tried cannabis or CBD (cannabidiol, an active ingredient in cannabis), particularly for sleep or anxiety,” says Dr. Heather Hirsch, head of the Menopause and Midlife Clinic at Harvard-affiliated Brigham and Women’s Hospital. “Adding to its appeal is that cannabis is now legal in so many places and works acutely for a couple of hours. You don’t need a doctor’s prescription. Socially, it may be easier to justify than using a medication. But why is there a movement toward saying okay to something that has unknown long-term effects, more than something that’s been studied and proven safe?” she asks.

Survey reports on who uses cannabis, why, and how

The new Harvard-led survey, published in the journal Menopause, looked at patterns of cannabis use in 131 women in perimenopause — the often years-long stretch before periods cease — along with 127 women who had passed through menopause. Participants were recruited through online postings on social media sites and an online recruitment platform. Nearly all survey respondents were white and most were middle-class, according to income reporting.

The vast majority (86%) were current cannabis users. Participants were split on whether they used cannabis for medical reasons, recreational purposes, or both. Nearly 79% endorsed it to alleviate menopause-related symptoms. Of those, 67% said cannabis helps with sleep disturbance, while 46% reported it helps improve mood and anxiety.

Perimenopausal women reported worse menopausal symptoms than their postmenopausal peers, as well as greater cannabis use to address their symptoms. More than 84% of participants reported smoking cannabis, while 78% consumed marijuana edibles, and nearly 53% used vaping oils.

One glaring limitation of the analysis is its self-selected group of participants, which lacked diversity and might skew results. But Dr. Hirsch wasn’t surprised by the high proportion reporting regular cannabis use. “I wouldn’t be surprised if those numbers reflect the broader population,” she says.

How might cannabis help menopause symptoms?

It makes sense that midlife women reported cannabis improves anxiety, mood, and sleep, Dr. Hirsch says. The drug likely helps all of these symptoms by “dimming the prefrontal cortex, the decision-making part of our brain.”

For many women, anxiety spikes during perimenopause, she notes. Common stressors during that time, such as aging parents or an emptying nest, add to the effects of dipping hormones. “It’s that feeling of, ‘I can’t turn my brain off.’ It’s really disturbing because they get in bed and can’t fall asleep, so they’re more tired, moody, and cranky the next day,” she explains. Dimming the prefrontal cortex enables people to calm down.

Hot flashes, often cited as the most common menopause symptom, did not improve as much from cannabis use, according to survey respondents. That too makes sense, Dr. Hirsch says, because the hypothalamus — the brain region considered the body’s thermostat — isn’t believed to be significantly affected by the drug.

No research yet on long-term effects

Given a lack of clinical trials objectively testing the effectiveness and safety of cannabis to manage menopause symptoms, more research is clearly needed.

“If people are finding relief from cannabis, great. But is it safe? We think so, but we don’t know,” she says. “There are no studies of middle-aged women using cannabis for 10 years, for as long as menopause symptoms often last. Are there going to be long-term effects on memory? On lung function? We don’t know.”

We can feel groggy when our sleep schedule is thrown off even just a little. So what happens when shift work requires people to regularly stay awake through the night and sleep during the day — and how can they protect their health and well-being?

What is shift work disorder?

Mounting evidence, including several new studies, paints a worrisome picture of the potential health fallout of nontraditional shift work schedules that affect 15% to 30% of workers in the US and Europe, including factory and warehouse workers, police officers, nurses, and other first responders.

So-called shift work disorder mainly strikes people who work the overnight or early morning shift, or who rotate their shifts, says Eric Zhou, an assistant professor in the Division of Sleep Medicine at Harvard Medical School. It is characterized by significant problems falling and staying asleep, or sleeping when desired. That’s because shift work disrupts the body’s normal alignment with the 24-hour sleep-wake cycle called the circadian rhythm.

“People who work 9-to-5 shifts are typically awake when the sun is up, which is aligned with their body’s internal circadian clock. But for shift workers, their work hours and sleep hours are misaligned with the natural cues to be awake or asleep,” Zhou says. “They’re working against the universe’s natural inclinations — not just their body’s.”

What’s the connection between shift work and health?

A 2022 research review in the Journal of Clinical Sleep Medicine links shift work to higher risks for serious health problems, such as heart attack and diabetes. This research suggests adverse effects can include metabolic syndrome (a cluster of conditions that raises the risks for heart disease, diabetes, and stroke), accidents, and certain types of cancer.

“The research is consistent and powerful,” Zhou says. “Working and sleeping during hours misaligned with natural light for extended periods of time is not likely to be healthy for you.”

How do new studies on shift work boost our understanding?

New research continues to add to and strengthen earlier findings, teasing out specific health effects that could stem from shift work.

• Shift workers on rotating schedules eat more erratically and frequently than day workers, snack more at night, and consume fewer healthier foods with potentially more calories, a study published online in Advances in Nutrition suggests. This analysis reviewed 31 prior studies involving more than 18,000 participants, comparing workers’ average food intake over 24 hours.
• Disrupting the circadian rhythm through shift work appears to increase the odds of colorectal cancer, a malignancy with strong ties to lifestyle factors, according to a 2023 review of multiple studies published online in the Journal of Investigative Medicine. Contributors to this higher risk may include exposure to artificial light at night, along with complex genetic and hormonal interactions, study authors said.

“Cancer understandably scares people, and the World Health Organization recognizes that shift work is a probable carcinogen,” Zhou says. “The combination of chronically insufficient and poor-quality sleep is likely to get under the skin. That said, we don’t fully understand how this happens.”

How can you protect your sleep — and your health?

If you work overnight or early morning shifts, how can you ensure you sleep more soundly and restfully? Zhou offers these evidence-based tips.

Time your exposure to bright and dim light. Graveyard shift workers whose work schedule runs from midnight through 8 a.m., for example, should reduce their light exposure as much as possible after leaving work if they intend to go right to sleep once they return home. “These measures could take the form of wearing blue light–blocking glasses or using blackout shades in your bedroom,” he says.

Make enough time for sleep on days off. “This is often harder than it sounds, because you’ll want to see your family and friends during nonwork hours,” Zhou says. “You need to truly protect your opportunity for sleep.”

Maintain a consistent shift work schedule. “Also, try to minimize the consecutive number of days you spend working challenging shifts,” he says.

Talk to your employer. Perhaps your boss can schedule you for fewer overnight shifts. “You can also ask your doctor to make a case for you to be moved off these shifts or have more flexibility,” Zhou says.

Look for practical solutions that allow you to get more restful sleep. “People engaged in shift work usually have responsibilities to their job as well as their family members, who often operate under a more typical 9-to-5 schedule,” he notes. “The goal is to preserve as strong a circadian rhythm as possible under the abnormal schedule shift work requires.”
