Another term for Korsakoff's is 'alcohol amnestic syndrome', amnestic meaning loss of memory. An encephalopathy is a disorder affecting the brain. Wernicke's encephalopathy usually develops suddenly. There are three main symptoms, though these are not always present, so diagnosis may be difficult. Immediate treatment is essential if Wernicke's is suspected.
Treatment consists of high doses of thiamine injected into a vein or muscle.
If treatment is carried out in time most symptoms should be reversed in a few hours. However, if Wernicke's is left untreated, or not treated in time, brain damage may result. In some cases the person may die. Korsakoff's psychosis may follow if the Wernicke's encephalopathy is untreated or not treated soon enough. It may also develop gradually.
