In DSM-II, this disorder is called Korsakov's psychosis (alcoholic)
This is a variety of chronic brain syndrome associated with long-standing alcohol use and characterized by memory impairment, disorientation, peripheral neuropathy and particularly by confabulation. Like delirium tremens, Korsakov's psychosis is identified with alcohol because of an initial error in identifying its cause, and therefore the term is confined to the syndrome associated with alcohol. The similar syndrome due to nutritional deficiency unassociated with alcohol is classified Psychosis associated with metabolic or nutritional disorder.

A. Amnestic Syndrome following prolonged heavy ingestion of alcohol.
B. Not due to any other physical or mental disorder.
In Dementia Associated with Alcoholism the disturbance is not limited to memory impairment.
