Diagnosis of intermediate-duration and subacute organic mental disorders in abstinent alcoholics

In a longitudinal study of 136 male alcoholics and controls, the authors found evidence of slowly reversible, subtle organic mental disorders in relation to prolonged abstinence from drinking by alcoholics. They suggest criteria for two new nosologic categories to describe these alcohol-related neuropsychiatric phenomena: (1) intermediate-duration organic mental disorder associated with alcoholism and (2) subacute organic mental disorder associated with alcohol abuse or alcoholism.
