Cortical atrophy in young adults with a history of hyperactivity in childhood

A computed tomographic (CT) brain scan study was conducted in 24 young males treated and followed up for hyperactivity since childhood. Compared to 27 matched controls, adults with a history of hyperactivity had a significantly greater frequency of cerebral atrophy. No differences in cerebellar atrophy frequency or in lateral cerebral ventricle-to-brain ratio (VBR) were found. The possible associations of hyperactivity or perhaps stimulant drug treatment to atrophic brain changes are discussed.
