title: Persistence of hyperactivity symptoms from childhood to adolescence and associated outcomes.
abstract: Hyperactive boys and matched controls from a large-scale epidemiological study, followed for at least three years to age 12, were compared on parent and teacher reports and assessments of attention, achievement, and intellectual functioning. Three outcome groups, based on presence or absence of hyperactivity symptoms, were derived and compared to the DSM-III description of ADD-H. Problem-free adolescents who were hyperactive in childhood were found to be more mature cognitively and behaviorally than those whose problems persisted.
