Neuropsychological function in young alcoholics and polydrug abusers

Abstract

The neuropsychological abilities of younger (mean age, 30) alcoholics and polydrug abusers were compared. On the basis of a clinician's rating of Halstead-Reitan results, 10 of 20 polydrug users (50%) and 4 of 20 alcoholics (20%) were found to show impairment. The polydrug users also scored significantly worse on Halstead's Impairment Index, Category Test, and Trail-Making Test, part B. Because the two groups were closely matched in age, education, Verbal IQ, and the medical history, the possibility is raised that, whereas 10 years of heavy drinking is not sufficient to yield neuropsychological impairment in younger persons, heavy multiple drug abuse might have more serious implications for cerebral functioning.
