The Natural History of ADD, part 2

Well, no sooner than I rant about ADD and ADHD not really existing, MSNBC informs me of this:

Long thought to be a condition of childhood that kids grow out of, recent research shows that up to 60 percent of children with ADHD continue having symptoms after they become adults.

It’s a common chronic disorder that affects about eight million grown-ups, or an estimated four to five percent of the U.S. adult population, according to researchers from Harvard Medical School and the World Health Organization. What’s surprising is that only about 20 percent of them realize it, experts say.

That’s just great. Before long we’ll have a diagnosis for every excuse people may have.
