The use of methylphenidate and other psychotropic drugs to treat preschool-aged children with attention-deficit/hyperactivity disorder (ADHD) has long been controversial because few data previously had been available to support the practice. Now a growing body of preliminary evidence indicates that these very young children can benefit from such treatment but that adverse events in this age group require special consideration.
Other studies are probing the potential long-term consequences of treatment and exploring the role of genetics in the disorder.
