A memory (i.e., amnestic) based psychosis induced by alcohol abuse; characterized by confusion and severe impairment of recent memory and confabulation (i.e., making-up events to compensate for memory loss).
A organic disorder affecting the brain that results in a memory defect in which new information fails to be learnt although events from the past are still recalled. The commonest cause is alcoholism, especially when this has led to a deficiency of vitamin B1.
A disease associated with chronic alcoholism, resulting from a deficiency of vitamin B-1. Patients sustain damage to part of the thalamus and cerebellum. Symptoms include inflammation of nerves, muttering delirium, insomnia, illusions and hallucinations and a lasting amnesia.
A neurological syndrome resulting from chronic alcoholism, characterized by confusion, confabulations, apathy, and amnesia.
Korsakoff's syndrome (a.k.a. Korsakoff's psychosis, amnesic-confabulatory syndrome), is a continuum of Wernicke's encephalopathy, though a recognised episode of Wernicke's is not always obvious. Individuals diagnosed with Korsakoff's syndrome usually have symptoms of severe anterograde and retrograde amnesia, as well as confabulation.
