The Truth About Gamers

Who is the average video gamer? Most of us think of gamers as teenage boys, but that stereotype is wrong! In reality, the average age of players is 35. About half of all gamers are over the age of 18, and 25 percent of them are over 50.

Until now, research on the health risks associated with playing video games has focused almost exclusively on children and teen gamers. A new study from the American Journal of Preventive Medicine is one of the first to investigate the effects of gaming on the adult population.

According to the researchers, adult gamers face many of the same health risks as their younger counterparts. Female gamers reported greater depression and lower health status than nonplayers, and male gamers were more likely to be overweight or obese than nonplayers. Both male and female players indicated a higher incidence of introversion and less social support from family and friends.

These sad results mirror the studies conducted on younger players. One recent study of younger players revealed poorer relationships with friends and family.

There is one bright light in the research on video game playing. A study in the Archives of Surgery reported that surgeons with video game-playing skills performed better in a simulated surgery course. Of course, most of us are not surgeons, so do not use this as an excuse to spend more time gaming.

I treat a lot of people — children, teens, and adults — who are hooked on video games, and I can tell you that their brains typically don’t look like the picture of health. With SPECT imaging, we see that video games work in the same area of the brain as cocaine and methamphetamine.

Excessive video game playing is detrimental to brain health so I usually recommend limiting game playing to no more than 30 minutes a day.

Does A High-Fat Diet Make You Stupid and Lazy?

The answer, unfortunately, is yes. At least that is the finding of a new animal study from British researchers. After eating a high-fat diet for just 10 days, rats showed short-term memory loss and less energy to exercise — in other words, they became more stupid and lazy.

The researchers compared the performance of the rats on a high-fat diet (55 percent of calories as fat) with rats on a low-fat diet (7.5 percent of calories as fat). In the rats with the high-fat diet, their muscles worked less efficiently, which lowered their energy levels, caused their hearts to work harder during exercise, and caused their hearts to increase in size.

The rats on the high-fat diet took longer to make their way through a maze and made more mistakes than the rats eating a low-fat diet.

The same way that food affects rats in a maze, it also affects us. We need to understand that the foods we eat on a daily basis affect our overall health, our energy levels, and our brain function. To optimize our brains and increase our energy levels, we need to eat brain healthy foods, including lean protein, complex carbohydrates — such as fruits, vegetables, whole grains, and beans — and healthy fats like olive oil.

Antidepressant Use Doubles

The use of antidepressant medication in the U.S. doubled from 1996 to 2005, according to a study in the Archives of General Psychiatry. In 1996, about 13 million people (about 6 percent of the population) were prescribed an antidepressant. That number soared to 27 million (more than 10 percent of the population) by 2005.

There are several things about this report that I find disturbing. First, antidepressants are the easy answer and often completely miss the root cause of depression. Next, less than 32 percent of the people being treated with antidepressants see a mental health professional for treatment. Instead, they are receiving a prescription from a general practitioner. Third, the use of psychotherapy among people being treated with antidepressants has decreased 10 percent.

Through our brain-imaging work at the Amen Clinics, we have identified seven different subtypes of depression, and each one requires individualized treatment. Prescribing antidepressants as a one-size-fits-all treatment doesn’t work and could be dangerous for some people. In addition, psychotherapy is a proven technique that has been found helpful in the treatment of depression.

Plus, antidepressant medications come with a host of unwanted side effects. In many cases, I recommend trying natural therapies first, such as supplements like SAMe and St. John’s wort, exercise, correcting negative thinking patterns, and supplementation with fish oil.

Funny Email

Does anybody else find all those jokes and stories that show up in your email inbox annoying? I typically do. However, I had to laugh when I read the following one. It is so true!

My Living Will

Last night, my husband and I were sitting in the living room and I said to him, “I never want to live in a vegetative state, dependent on some machine and fluids from a bottle. If that ever happens, just pull the plug.”

He got up, unplugged the computer, and threw out my wine.

We could all learn a lesson or two about brain health from this funny story. Spend less time on your computer and more time in face-to-face contact with the people you love. And hold the alcohol.

Brain Trauma Letter to the Editor

In my practice, I have worked with many people who have suffered brain injuries, and I have seen how it can devastate not only their lives but also the lives of their loved ones. That is why I strongly urge people to avoid activities that put them at high risk for brain trauma — such as skateboarding, tackle football, and bicycling — and why I insist that people wear a proper-fitting helmet whenever engaging in such high-risk activities.

In California, it’s a law that children must wear a helmet while skateboarding, bicycling, in-line skating, rollerskating, or riding a scooter. Parents can face criminal charges if their child is injured while not wearing a helmet.

I recently came across a hauntingly sad letter to the editor in a local newspaper that describes the heartache and pain a family can experience when a child who isn’t wearing a helmet suffers a brain injury. Here is the letter, reprinted with permission from the Palisadian-Post, a newspaper in Pacific Palisades, California.

“Our friend Sean fell off his skateboard last Thanksgiving Day, hit his head and spent the next week in a coma fighting for his life. Sean, a Loyola High School freshman at the time, survived. He experienced two brain surgeries and had to wear a helmet 24/7 for four months. The doctors removed Sean’s skull, sewed it into his abdomen to keep the tissue alive, and painstakingly waited for the swelling to go down in his brain so they could put his skull back, but he survived. He now walks, he talks, he laughs, he went back to school. He’s not the same Sean; he has a long road ahead of him and cannot yet play his beloved sports, but he is one of the lucky ones — he lived.

In 2002, California amended its helmet law to include not only bikes, but skateboards, Razor scooters and in-line skates. All children (and their passengers) under the age of 18 must wear a helmet on a bike, a skateboard, a Razor scooter, and while skating. Sean was not wearing a helmet on this fateful Thanksgiving Day. Sean, and his parents, broke the law. Family, friends, and strangers from literally around the world rallied to the aid of Sean and his parents. Who could not empathize with this story, this tragedy? Two loving, conscientious parents praying for the life of their only child, a strong, polite, intelligent, athletic Eagle Scout. What most people didn’t know, however, is that Sean’s parents were also fighting a different kind of battle: they broke the law and there would be consequences.

The emergency room workers and surgeon who gave up their Thanksgiving dinners to save Sean’s life were amazing. They were quick to react, skillful and professional. But they were not kind. Within hours of the accident, Sean’s parents found they were under investigation. The validity of their parenting skills were under attack. First by the doctors, then by the police, followed by the mandatory social service investigation. They broke the law, they were considered negligent. It was the job of the state to determine whether Sean was safe in their care.

There are many accidents and events in our children’s lives that we cannot prevent or control. This is not one f them. Helmet laws are there to keep our kids safe and prevent horrible tragedies like Sean’s. Let’s start protecting our children. It’s not that hard: No helmet, no skateboard! No helmet, no Razor! Not in the driveway, not on the sidewalk, not just on the quick ride over to a friend’s house. There’s been enough tragedy in Pacific Palisades this past year. Let’s try to prevent another one. And, by the way, the helmets need to be buckled.”
