ADHD: By the numbers

Here’s a stunner: The U. S. prescribes more drugs for ADHD than the rest of the world's nations combined, according to a recent article in Nature.

And, the steep rise in ADHD diagnoses in recent years — a 41 percent increase over the past decade — has only raised fears among some doctors and parents that millions of kids, considered overactive or unfocused, who are on stimulants such as Ritalin and Adderall, don’t actually need them.

“We need to ensure balance,” CDC director Dr. Thomas Frieden told The New York Times. “The right medications for ADHD, given to the right people, can make a huge difference. Unfortunately, misuse appears to be growing at an alarming rate.”

Some observers say the spike in diagnoses is due to improved awareness and screening of the neurobehavioral disorder. Others think that millions of healthy, rambunctious kids are simply being mislabeled.

“There’s a tremendous push where if the kid’s behavior is thought to be quote-unquote abnormal — if they’re not sitting quietly at their desk — that’s pathological, instead of just childhood,” Dr. Jerome Groopman, a Harvard Medical School professor, told The New York Times.

No doubt the ADHD debate will continue. As it does, here are a few numbers that give important context to the issue:
