Korsakoff psychosis

[Cami]

Korsakoff psychosis is a complication of Wernicke encephalopathy and causes memory loss for recent events, confusion, and behavioral changes.
(See also Drug Use and Abuse.)
Korsakoff psychosis occurs in 80% of people with untreated Wernicke encephalopathy, which is a brain disorder caused by a type of vitamin deficiency that can occur in people who drink large amounts of alcohol for a long time. Korsakoff psychosis is sometimes triggered by a severe bout of delirium tremens, which is a form of alcohol withdrawal, whether a typical attack of Wernicke encephalopathy occurs prior or not. Other causes include head injuries, stroke, bleeding within the brain, and certain brain tumors (rarely).
