Making friends and finding social opportunities can sometimes be difficult, particularly for children with neurodevelopmental disabilities, such as autism spectrum disorder, attention deficit hyperactivity disorder, or an intellectual disability. Here’s what parents can do to help.

Building inclusive communities

Friendships and social connections are an important aspect of our lives. They provide a sense of belonging and allow people to be included in their communities.

People with neurodevelopmental disabilities may communicate, learn, and behave differently. Sometimes these differences make it harder than usual to develop friendships and participate in social activities.

But parents and others can help create more inclusive communities and opportunities to build social relationships, especially for people with neurodiverse abilities.

Below are some tips and strategies to help children learn and develop the social and emotional skills they need to make friends.

Practice at home: Tips for common social situations

Navigating social settings and making friends involve many skills you can practice with children at home.

• Greetings and questions. Make a habit of practicing greetings throughout the day. Model good listening for your child, and take turns asking and answering conversation starters like, “How are you?”
• Calm body movements. Sometimes it can be hard for children with neurodevelopmental disabilities to keep a calm body. Have your child practice giving their body enough room and keeping personal space between themselves and others by using an arm’s-length distance.
• Appropriate level of voice. Encourage your child to listen and match the level of your voice. Imagine your voice has a volume dial and practice turning the volume up and down.
• Eye contact. Looking directly into someone’s eyes can be difficult, so help your child instead look at different parts of your face or practice looking at their own eyes in the mirror.
• Reading and responding to social signals. People regularly communicate using more than just words. Social signals are the variety of ways in which we communicate through body language and facial expressions. Often this can be tricky to detect for children who are neurodiverse. Help your child recognize common social signals by asking what someone’s body or face might be saying.

Rerouting challenging behaviors to help children build friendships

Challenging behaviors may get in the way of making and keeping friends. It is important to address challenging behaviors like impulsivity and aggression through therapies and programming. Additionally, practicing the following fundamental skills can help reduce challenging behaviors.

• Patience. Learning how to wait for a turn to play or a time to speak in a conversation is an important social skill. Practice waiting with a timer, gradually building up from 10 seconds, to one minute, to five minutes.
• Flexibility. Help your child make compromises using first/then statements, such as, “First we play your way, then my way.” Model flexible play and redirect with new toys to show how play can evolve.
• Communicating strong emotions.Handling strong feelings can be difficult sometimes. Practice communicating these feelings effectively either by asking for help, using an emotions board, or taking a break.

How to throw a wide net socially

Encouraging social opportunities is an important part of supporting friendships and social relationships for children with neurodevelopmental disabilities. Social spaces offer chances for children who are neurodiverse to find activities they enjoy. They are able to practice the social and emotional skills they are learning and even meet other children practicing these same skills.

• Structure and organize play dates. Set up the environment before a play date by making a list of activities to do with a friend, then picking out of a hat which activities to do and in what order.
• Make a list of things that are fun to do and invite others to join. Look for free or low-cost programs or events out in the community.
• Connect with other parents of children with disabilities. Set up an activity for your children like an ice cream date, going on a walk, or a game night with adults and kids together. These encounters can give rise to repeat, planned social interactions.
• Check out organizations in the community for children with disabilities, like Special Olympics, or recreational programs that foster inclusive environments through Unified Sports.
• Look into facilitated recreational activities like a Lego club or pizza parties with teachers. Plan to bring a support person if needed.

Your child’s doctor or teacher may be able to suggest additional community or web-based resources designed to help families support friendships for children with neurodiverse abilities.

You may have heard recent news reports about a company that knowingly sold defective lead testing machines that tested tens of thousands of children between 2013 and 2017. Or wondered about lead in tap water after the widely reported problems with lead-contaminated water in Flint, Michigan. Reports like these are reminders that parents need to be aware of lead — and do everything they can to keep their children safe.

How is lead a danger to health?

Lead is poisonous to the brain and nervous system, even in small amounts. There really is no safe level of lead in the blood. We particularly worry about children under the age of 6. Not only are their brains actively developing, but young children commonly touch lots of things — and put their hands in their mouths. Children who are exposed to lead can have problems with learning, understanding, and behavior that may be permanent.

How do children get exposed to lead?

In the US, lead used to be far more ubiquitous than it is now, particularly in paint and gas. Yet children can be exposed to lead in many ways.

• Lead paint. In houses built before 1978, lead paint can sometimes be under other paint, and is most commonly found on windowsills or around doors. If there is peeling paint, children can sometimes ingest it. Dust from old paint can land on the floor or other surfaces that children touch with their hands (and then put their hands in their mouths). If there was ever lead paint on the outside of a house, it can sometimes be in the dirt around a house.
• Leaded gas. While leaded gas was outlawed in 1996, its use is still allowed in aircraft, farm equipment, racing cars, and marine engines.
• Water passing through lead pipes. Lead can be found in the water of older houses that have lead pipes.
• Other sources. Lead can also be found in some imported toys, candles, jewelry, and traditional medicines. Some parents may have exposure at work or through hobbies and bring it home on their hands or clothing. Examples include working in demolition of older houses, making things using lead solder, or having exposure to lead bullets at a firing range.

What can parents do to protect children from lead?

First, know about possible exposures.

• If you have an older home, get it inspected for lead if you haven’t done so already. (If you rent, federal law requires landlords to disclose known lead-based paint hazards when you sign a lease.) Inspection is particularly important if you are planning renovations, which often create dust and debris that increase the risk of exposure. Your local health department can give you information about how to do this testing. If there is lead in your home, don’t try to remove it yourself! It needs to be done carefully, by a qualified professional, to be safe.
• Talk to your local health department about getting the water in your house tested. Even if your house is new, there can sometimes be older pipes in the water system. Using a water filter and taking other steps can reduce or eliminate lead in tap water.
• If you have an older home and live in an urban area, there can be lead in the soil. You may want to have the soil around your house tested for lead. Don’t let your child play in bare soil, and be sure they take off their shoes before coming in the house and wash their hands after being outside.
• Learn about lead in foods, cosmetics, and traditional medications.
• Learn about lead in toys, jewelry, and plastics (yet another reason to limit your child’s exposure to plastic).

Second, talk to your pediatrician about whether your child should have a blood test to check for lead poisoning. The American Academy of Pediatrics recommends:

• Assessing young children for risk of exposure at all checkups between 6 months and 6 years of age, and
• Testing children if a risk is identified, particularly at 12 and 24 months. Living in an old home, or in a community with lots of older homes, counts as a risk. Given that low levels of lead exposure that can lead to lifelong problems do not cause symptoms, it’s always better to be safe than sorry. If there is any chance that your child might have an exposure, get them tested.

How is childhood lead exposure treated?

If your child is found to have lead in their blood, the most important next step is to figure out the exposure — and get rid of it. Once the child is no longer exposed, the lead level will go down, although it does so slowly.

Iron deficiency makes the body more vulnerable to lead poisoning. If your child has an iron deficiency it should be treated, but usually medications aren’t used unless lead levels are very high. In those cases, special medications called chelators are used to help pull the lead out of the blood.

When I worked at Greenpeace for five years before I attended medical school, a popular slogan was, “Think globally, act locally.” As I write this blog about climate change and hay fever, I wonder if wiping off my computer that I’ve just sneezed all over due to my seasonal allergies counts as abiding by this aphorism? (Can you clean a computer screen with a tissue?)

Come to think of it, my allergies do seem to be worse in recent years. So do those of my patients. It seems as if I’m prescribing nasal steroids and antihistamines, recommending over-the-counter eye drops, and discussing ways to avoid allergens much more frequently than in the past. Are people more stressed out, working harder, sleeping less, and thus more susceptible to allergies? Or, are the allergies themselves actually worse? Could the worsening of climate change explain why the rates of allergies and asthma have been climbing steadily over the last several decades?

There’s more pollen and a longer pollen season

Seasonal allergies tend to be caused disproportionately by trees in the spring, grasses in the summer, and ragweed in the fall. The lengthening interval of “frost-free days” (the time from the last frost in the spring to the first frost in the fall) allows more time for people to become sensitized to the pollen — the first stage in developing allergies — as well as to then become allergic to it. No wonder so many more of my patients have been complaining of itchy eyes, runny nose, and wheezing.

In many places in the United States, due to climate change, spring is now starting earlier and fall is ending later, which, yearly, allows more time for plants and trees to grow, flower, and produce pollen. This leads to a longer allergy season. According to a study at Rutgers University, from the 1990s until 2010, pollen season started in the contiguous United States on average three days earlier, and there was a 40% increase in the annual total of daily airborne pollen. More recent research in North America shows rising concentrations of sneeze-inducing pollens and lengthening pollen seasons from 1990 to 2018, largely driven by climate change.

Climate change is increasing the potency of pollen

In addition to longer allergy seasons, allergy sufferers have other things to fret about with climate change. When exposed to increased levels of carbon dioxide, plants grow to a larger size and produce more pollen. Some studies have shown that ragweed pollen, a main culprit of allergies for many people, becomes up to 1.7 times more potent under conditions of higher carbon dioxide. With warming climates, the geographic distribution of pollen-producing plants is expanding as well; for example, due to warmer temperatures, ragweed species can now inhabit climates that were formerly inhospitable.

Other unfortunate consequences of climate change, which we are already witnessing, include coastal flooding as the arctic ice sheets melt, causing the sea levels to rise; and more extreme weather, such as storms and droughts. With the increased coastal flooding, mold outbreaks are more common, which can trigger or worsen allergic reactions and asthma. More extreme weather events, such as thunderstorms, are associated with an increase in emergency department visits for asthma attacks. (It is unclear why this is the case, but one theory suggests that the winds associated with thunderstorms kick up a tremendous amount of pollen.) Allergies and asthma are closely associated, with many people, this author included, having “allergic asthma” that is likely to worsen as climate change progresses.

So what can an allergy sufferer do?

Even as the allergic environment changes in conjunction with our climate, there are steps you can take to manage the impact of seasonal allergies and reduce sneezing and itchy eyes.

• Work with your doctor to treat your allergies with medications such as antihistamines, nasal steroids, eye drops, and asthma medications if needed. If you take other medications that may interact with over-the-counter allergy medications such as Benadryl or Sudafed, let your doctor know.
• Discuss with your doctor whether you would benefit from allergy testing, a referral to an allergist, or prevention methods like allergy injections or sublingual immunotherapy, which, by exposing your body in a controlled manner, slowly conditions your immune system not to respond to environmental allergens.
• Track the local pollen count and avoid extended outdoor activities during peak pollen season, on peak pollen days. However, most doctors would agree that it isn’t healthy to cut back on exercise, hobbies, or time in nature, so this is a less than satisfying solution at best. You could plan for an indoor exercise program on high-pollen days.
• Wash clothing and bathe or shower after being outdoors to remove pollen.
• Close windows during peak allergy season or on windy days.
• Wear a mask when outdoors during high pollen days, and keep car windows rolled up when driving.
• If your house has been flooded, be on the lookout for mold. There are services that you can hire that will inspect your home for mold, and remove the mold if it is thought to be harmful.
• Have as small a carbon footprint as possible and plant trees. Even though they are responsible for some of the pollen that many of us choke and gag on each spring, summer, and fall, trees contribute to their environment by taking in carbon dioxide and producing the oxygen we breathe, thereby improving air quality. We have to protect and plant trees, even as allergy sufferers, as climate change is arguably the biggest threat that we, as a species, now face.

Scientific advances have brought us scores of new drugs in recent years. In the US, one major agency — the FDA — is responsible for making sure that the drugs they approve are safe and effective. Yet there were more than 14,000 drug recalls in the last 10 years, according to FDA statistics. That averages out to nearly four drug recalls a day!

Why are drug recalls so common, and how can you maximize safety when taking the medicines you need?

Why do so many drug recalls occur?

The FDA approves prescription drugs if research shows a medicine is safe and effective. Usually the risks are well known by the time approval is granted. For over-the-counter drugs, the bar is lower: proof that they work is not required, but the FDA still maintains oversight for safety.

Drug recalls are common because:

• Rare side effects may be missed in clinical trials. Studies leading to drug approval might have hundreds or thousands of study subjects. But a rare problem may not be detected until tens of thousands of people have taken a drug.
• Study subjects tend to be healthier than the general population. When you’re trying to figure out if a drug works, the chances of success are higher and reliability of results is greater if study subjects are healthy. Once a drug is approved, people taking it may be older, less healthy, or taking multiple drugs for health issues.
• Problems during or after manufacturing can make a safe drug harmful. Examples include bacterial contamination, incorrect labeling, and improper storage.
• Bad behavior by drug makers may affect drug safety. For example, multiple over-the-counter supplements marketed for male sexual performance were recalled in recent years because they were laced with prescription drugs for erectile dysfunction.

Are most drug recalls high-risk?

Fewer than one in 10 poses a serious health risk. The FDA grades risk severity for recalls as follows:

• Class I is dangerous and poses a serious health risk (a hand sanitizer contaminated with methanol)
• Class II might cause a temporary or slight risk of serious harm (a diabetes medicine stored at the wrong temperature)
• Class III is unlikely to cause any harm to health, but there is a violation of FDA requirements (an ointment for dermatitis in damaged tubes).

Between 80% and 90% of drug recalls are Class II.

In 2022, 6% of recalls were Class 1, 86% were Class II, and 7% were Class III.

How do drug recalls happen?

The FDA inspects drug manufacturing facilities every two to three years. The agency also tests thousands of drugs each year.

Problems spotted during inspections, concerns identified by drug makers, or problems reported by patients or health care professionals can prompt a recall. The FDA then assigns a risk classification, supervises actions taken by the drug maker to remedy the problem, and monitors the product to make sure the problem is eliminated.

Drug recalls in the US are almost always voluntary. That means the drug maker acknowledges the problem and takes corrective action rather than waiting for a possible mandate from the FDA.

How can you stay informed about medicines you use?

Here are some practical measures to take:

• Sign up to receive texts or emails about recalls, market withdrawals, and safety alerts from the FDA.
• When filling prescriptions, take a good look at your medicine. Pills should not be discolored or crumbling, or have an unusual odor. If your prescription hasn’t changed, a refill should look similar to what you’ve taken in the past. If you suspect a problem, contact your pharmacist or the health care professional who prescribed it. And if you do confirm a problem, you can report it to the FDA.
• If you learn of a recall for a drug you take, check the lot number on the package to see if your medication is affected. If the risk is classified as high (Class I), contact your doctor right away for advice. For many recalled drugs, there are safe and effective alternatives.
• A recall notice will tell you if the medicine can be replaced or if you can be reimbursed. If you are instructed to dispose of medication, do so safely.

Another way to limit your potential exposure to recalled drugs is to take fewer drugs. Review your medication list with your doctor regularly and take only what you truly need.

The bottom line

News on drug recalls may not inspire confidence. It might make you wonder if the drugs you take are safe. In general, yes: the vast majority of medicines on the market have an excellent safety profile. But with more than 1,000 drug recalls every year, there’s plenty of room for improvement by drug makers and good reason to encourage better regulation of the industry.

For people with obesity, weight-loss surgery can reverse or greatly improve many serious health issues, such as diabetes, high blood pressure, and pain. But these procedures also change how the body metabolizes alcohol, leaving people more likely to develop an alcohol use disorder. A new study finds that one type of surgery, gastric bypass, may increase the dangers of drinking much more than other weight-loss strategies.

“Alcohol-related problems after weight-loss surgery are a known risk. That’s one reason we require people to abstain from alcohol for at least six months — and preferably a full year — before any weight-loss surgery,” says Dr. Chika Anekwe, an obesity medicine specialist at the Harvard-affiliated Massachusetts General Hospital Weight Center. The new findings are interesting and make sense from a biological perspective, given the differences in the surgeries, she adds.

How does weight loss surgery affect alcohol absorption?

Weight-loss surgeries dramatically reduce the size of the stomach.

• For a sleeve gastrectomy, the most common procedure, the surgeon removes about 80% of the stomach, leaving a banana-shaped tube.
• For a gastric bypass, a surgeon converts the upper stomach into an egg-sized pouch. This procedure is called a bypass because most of the stomach, the valve that separates the stomach from the small intestine (the pylorus), and the first part of the small intestine are bypassed.

The lining of the stomach contains alcohol dehydrogenase, an enzyme that breaks down alcohol. After weight-loss surgery, people have less of this enzyme available. So drinking wine, beer, or liquor will expose them to a higher dose of unmetabolized alcohol. Some alcohol is absorbed directly from the stomach, but most moves into the small intestine before being absorbed into the bloodstream.

After a sleeve gastrectomy, the pyloric valve continues to slow down the passage of alcohol from the downsized stomach to the small intestine. But with a gastric bypass, the surgeon reroutes the small intestine and attaches it to the small stomach pouch, bypassing the pyloric valve entirely. As a result, drinking alcohol after a gastric bypass can lead to extra-high blood alcohol levels. That makes people feel intoxicated more quickly and may put them at a higher risk of alcohol use disorders, says Dr. Anekwe.

Findings from the study on weight loss surgery and alcohol

The study included nearly 7,700 people (mostly men) from 127 Veterans Health Administration centers who were treated for obesity between 2008 and 2021. About half received a sleeve gastrectomy. Nearly a quarter underwent gastric bypass. Another 18% were referred to MOVE!, a program that encourages increased physical activity and healthy eating.

After adjusting for participants’ body mass index and alcohol use, researchers found that participants who had gastric bypass were 98% more likely to be hospitalized for alcohol-related reasons than those who had sleeve gastrectomy, and 70% more likely than those who did the MOVE! program. The rate of alcohol-related hospitalizations did not differ between people who had sleeve gastrectomy and those who did the MOVE! program.

The health harms of alcohol use disorder

Alcohol use disorder can lead to numerous health problems. Some require hospitalization, including alcoholic gastritis, alcohol-related hepatitis, alcohol-induced pancreatitis, and alcoholic cardiomyopathy. As the study authors note, people who had gastric bypass surgery had a higher risk of being hospitalized for an alcohol use disorder, even though they drank the least amount of alcohol compared with the other study participants. This suggests that change in alcohol metabolism resulting from the surgery likely explains the findings.

Advice on alcohol if you’ve had weight-loss surgery or are considering it

“We recommend that people avoid alcohol completely after any type of weight-loss surgery,” says Dr. Anekwe. A year after the surgery, an occasional drink is acceptable, she adds, noting that most patients she sees don’t have a problem with this restriction.

People who undergo weight-loss surgeries have to be careful about everything they consume to ensure they get adequate amounts of important nutrients. Like sugary drinks, alcohol is devoid of nutrients — yet another reason to steer clear of it.

Gastric bypass has become less popular than sleeve gastrectomy over the past decade, mostly because it’s more invasive and slightly riskier. While the new study suggests yet another downside of gastric bypass, Dr. Anekwe says it can still be a viable option for people with severe obesity, as bypass leads to more weight loss and better control of blood sugar than the sleeve procedure.
