Abstract
Attention deficit/hyperactivity disorder is often treated with stimulant drugs such as methylphenidate. However, this treatment remains controversial, as some studies have suggested that sensitization to these drugs of abuse predispose towards adult drug addiction. A new study, using juvenile rats, now shows that chronic treatment with methylphenidate during adolescence actually reduces drug-seeking behavior during adulthood.
Attention deficit/hyperactivity disorder (ADHD) is a complex condition that can include elements of hyperactivity, impulsive behavior and inattention. Its prevalence in childhood is variably estimated to be between 2 and 14%, and is often treated with stimulant drugs such as methylphenidate (Ritalin) or D-amphetamine (Dexedrine).
