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).
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]
Alcohol-related brain damage [1] [2] alters both the structure and function of the brain as a result of the direct neurotoxic effects of alcohol intoxication or acute alcohol withdrawal. Increased alcohol intake is associated with damage to brain regions including the frontal lobe , [ 3 ] limbic system , and cerebellum , [ 4 ] with widespread ...
