Korsakoff syndrome is a type of brain disorder associated with long-term heavy alcohol consumption. It is characterized by confusion, disorientation, and memory impairment, among other symptoms. It is caused by a deficiency in thiamine (vitamin B1), which can lead to damage in the parts of the brain responsible for memory and learning. It is not directly related to liver damage or physical symptoms such as trembling, sweating, and hallucinations.
