A.D.H.D. Experts Re-evaluate Study’s Zeal for Drugs - New York Times Twenty years ago, more than a dozen leaders in child psychiatry received $11 million from the National Institute of Mental Health to study an important question facing families with children with attention deficit hyperactivity disorder: Is the best long-term treatment medication, behavioral therapy or both? The study’s primary paper, published in 1999, concluded that medication “was superior to behavioral treatment” by a considerable margin — the first time a major independent study had reached that conclusion. Combining the two, it said, “did not yield significantly greater benefits than medication” alone for symptoms of the disorder. In what became a simple horse race, medication was ushered into the winner’s circle.
