Korsakoff syndrome (KS) [1] is a disorder of the central nervous system characterized by amnesia, deficits in explicit memory, and confabulation.This neurological disorder is caused by a deficiency of thiamine (vitamin B 1) in the brain, and it is typically associated with and exacerbated by the prolonged, excessive ingestion of alcohol.

Wernicke-Korsakoff syndrome (WKS) is the combined presence of Wernicke encephalopathy (WE) and alcoholic Korsakoff syndrome (AKS [clarification needed]). Due to the close relationship between these two disorders, people with either are usually diagnosed with WKS as a single syndrome. It mainly causes vision changes, ataxia and impaired memory. [2]
Up to 80% of WE patients who misuse alcohol develop Korsakoff's syndrome. [39] In Korsakoff's, is usually observed atrophy of the thalamus and the mammillary bodies, and frontal lobe involvement. [39] In a study, half of Wernicke–Korsakoff cases had good recovery from the amnesic state, which may take from 2 months to 10 years. [2]
This is a list of major and frequently observed neurological disorders (e.g., Alzheimer's disease), symptoms (e.g., back pain), signs (e.g., aphasia) and syndromes (e.g., Aicardi syndrome). There is disagreement over the definitions and criteria used to delineate various disorders and whether some of these conditions should be classified as ...
Korsakoff's syndrome is unique because it involves both anterograde and retrograde amnesia. [45] Drug-induced amnesia is intentionally caused by injection of an amnestic drug to help a patient forget surgery or medical procedures, particularly those not performed under full anesthesia, or likely to be particularly traumatic. Such drugs are also ...
Korsakoff's syndrome and Wernicke–Korsakoff syndrome are particular forms of alcohol related brain injury which may be related to alcohol related dementia. [18] Many experts use the terms alcohol (or alcoholic) dementia to describe a specific form of ARD, characterized by impaired executive function (planning, thinking, and judgment).
Trisomy 18 — also known as Edwards syndrome — is a chromosomal condition that is fatal in all but very rare cases, Dr. Silvana Ribaudo, an ob-gyn at NewYork-Presbyterian/Columbia University ...
Confabulation can occur with nervous system injuries or illnesses, including Korsakoff's syndrome, Alzheimer's disease, schizophrenia, and traumatic brain injury. It is believed that the right frontal lobe of the brain is damaged, causing false memories. Children are especially susceptible to forced confabulation as they are highly impressionable.
