Wernicke-Korsakoff syndrome is a brain disorder due to thiamine deficiency.

Korsakoff psychosis; Alcoholic encephalopathy; Encephalopathy - alcoholic; Wernicke's disease

Wernicke's encephalopathy and Korsakoff syndrome are different conditions that are both due to brain damage caused by a lack of vitamin B1 (thiamine).

A lack of vitamin B1 is common in people with alcoholism. It is also common in persons whose bodies do not absorb food properly (malabsorption), such as sometimes occurs after obesity surgery.

Korsakoff syndrome, or Korsakoff psychosis, tends to develop as Wernicke's symptoms go away. Wernicke's encephalopathy causes brain damage in lower parts of the brain called the thalamus and hypothalamus. Korsakoff psychosis results from damage to areas of the brain involved with memory.
