Two subgroups of hyperactives as adults: correlations of outcome

This prospective study explored the association of continuing symptoms of the hyperactive syndrome with adult outcome. A fifteen year follow-up compared 61 hyperactive subjects and 41 matched controls. Outcome measures examined included continuing symptoms of the hyperactive syndrome, antisocial behaviour, substance use, and emotional difficulties. Two subgroups of the hyperactive population were identified. Those hyperactive subjects with moderate or severe continuing symptoms were characterized by significant emotional difficulties, alcohol use, and antisocial behaviour. By contrast, hyperactive subjects with none or only mild continuing symptoms at follow-up did not have other difficulties in psychosocial functioning, and were, in addition, similar to the control group in many respects. The importance of continuing symptoms in determining the adult outcome of children with a diagnosis of ADDH is discussed. Accordingly, the need for comprehensive early, and ongoing interventions is emphasized.
