Korsakov's Psychosis, also known as Korsakoff Syndrome, is a neurological disorder that occurs due to thiamine deficiency and is characterized by severe memory loss and cognitive impairment. Some common synonyms for Korsakov's Psychosis include Korsakoff's Psychosis, Korsakoff's Syndrome, Korsakoff's Amnesia, and Wernicke-Korsakoff Syndrome. While these terms are often used interchangeably, they may refer to slightly different manifestations of the same underlying condition. Korsakov's Psychosis can be caused by chronic alcohol abuse, malnutrition, or other medical conditions that affect the body's ability to absorb and utilize thiamine. Treatment typically involves thiamine supplements and supportive care to address cognitive and behavioral symptoms.
