Traumatized? Playing Tetris may reduce flashbacks

The rapid-fire visual puzzles that make Tetris so engrossing may also make the video game a promising treatment for post-traumatic stress, a new study suggests.

Recurring, intrusive thoughts of a traumatic event (or events) are one of the hallmark symptoms of post-traumatic stress disorder (PTSD), a type of anxiety disorder. According to the study, which appears in the journal PLoS ONE, playing Tetris soon after a traumatic experience appears to protect against these flashbacks, by distracting the brain from the event and short-circuiting how upsetting memories and images are stored.

Can infant formula prevent type 1 diabetes?

A new study published in the New England Journal of Medicine may offer clues in reducing the number of people with type 1 diabetes.

Finnish researchers found that infants weaned to a formula that was hydrolyzed and casein-based were less likely to have indications of developing type 1 diabetes than those who received cow's milk. Casein is a milk protein. "Hydrolyzed" means the milk has gone through a process to break down large proteins, said study author Dr. Mikael Knip of the University of Helsinki.

The triathlon journey

The triathlon journey

I was on a plane about a year ago getting ready to take off, when I got a call from the director of our unit at CNN. She is a triathlete, and in very good shape. “Hey, Sanjay! I have a great idea. You should do the New York Triathlon with me, and we can pick six viewers around the country to do it with us,” she said. At this point, the flight attendant came around and politely asked me to turn off my phone. “Roni, uh. Yeah sure. Sounds great,” was my reply. And, that is how I found myself signed up for my first-ever triathlon.

Truth is, I never dreamed that I could do this. With a busy schedule at the hospital, three children and constant travel around the world, I immediately worried that I wouldn’t be able to train properly or adhere to the diet necessary to be a triathlete.

When July came around, and we were just days from the race, I reflected on the past several months. I realized my whole approach to fitness had changed. As busy as life is, I somehow found time to break a sweat every single day.

Ready for a challenge? Just TRI it!

We're at the starting line of CNN's 2011 Fit Nation Challenge. That means we're looking for six CNN viewers to race in the 2011 New York City Triathlon with Dr. Sanjay Gupta. Are you interested?

Here are a few things to know: CNN is looking for people who need a little help getting fit, not people who have already raced a triathlon (or marathon, for that matter). If you're serious about getting healthy and changing your life, this is the challenge for you!

The six lucky viewers will be given everything they need to train for this race and their new, healthy lifestyle. The event is composed of a 1-mile swim, a 25-mile bike ride and a 10k run. All we ask in return is dedication, commitment, and regular contributions for our blog. If you fit the bill, send us a video .

Not sure if you're ready for this?

Hear from some of this year's "six-pack". This challenge changed their lives and it can change yours, too! So what are you waiting for? Just TRI it and soon you could be off and swimming, biking, and running with Dr. Gupta!

CDC: Childhood ADHD rate rises 22 percent

Nearly one in 10 children in the U.S. has been diagnosed with attention deficit hyperactivity disorder (ADHD), and the rate appears to be growing, according to a report released Wednesday by the Centers for Disease Control and Prevention (CDC).

The percentage of children ages 4 to 17 who have ever been diagnosed with ADHD rose from 7.8 percent to 9.5 percent between 2003 and 2007—a 22 percent increase, the CDC found. The report was based on the results of the National Survey of Children's Health, a nationwide telephone survey of parents.
