...corrected with medicine, much the way daily insulin shots help diabetics. There is no blood test, no PET scan, no physical exam that can determine who has it and who does not. For many children, Ritalin is the answer simply because it works. "It's a fixed, stable, low-dose drug," says Dr. Philip Berent, consulting psychiatrist at the Arlington Center for Attention Deficit Disorder in Arlington Heights, Ill. He argues that critics who claim diet, exercise or other treatments work just as well as Ritalin are kidding themselves. "The quickest way to end that criticism is to spend...

Our earlier TV encounters had been so cryptic, so unsatisfying: Starr on his driveway comparing himself to Joe Friday and bidding reporters vaya con Dios.

"They haven't done the science," says TIME science editor Phillip Elmer-DeWitt. "They haven't reproduced it. It isn't science until you do it a second time."
