Alcohol misuse and neuropsychological deficits in men.

The 111 men alcoholics studied were of average intelligence or better and showed no gross memory deficit, but did show deficits on the Category, Tactual Performance and Trail Making Tests and the Impairment Index of the Halstead-Reitan neuropsychological test battery. Impairment of the fronto-limbic-diencephalic system may explain the findings.
