Attention Deficit-Hyperactivity Disorder Press Releases

For decades, doctors who have treated children with both attention deficit-hyperactivity disorder (ADHD) and tics have been warned not to prescribe methylphenidate (Ritalin), the most common drug for ADHD, because of a concern that it would make the tics worse. Now, the first randomized, placebo-controlled clinical trial of methylphenidate and another drug, clonidine (Catapres), has found that in fact these drugs do not adversely affect tics. The researchers also found that a combination of the drugs is more effective than either drug alone.
