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.
When it occurs simultaneously with alcoholic Korsakoff syndrome it is known as Wernicke–Korsakoff syndrome. [3] [4] Classically, Wernicke encephalopathy is characterised by a triad of symptoms: ophthalmoplegia, ataxia, and confusion. Around 10% of patients exhibit all three features, and other symptoms may also be present. [5]
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 .

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). [5]
Wernicke encephalopathy and Korsakoff syndrome are forms of dry beriberi. [6] Diagnosis is based on symptoms, low levels of thiamine in the urine, high blood lactate, and improvement with thiamine supplementation. [9] Treatment is by thiamine supplementation, either by mouth or by injection. [1] With treatment, symptoms generally resolve in a ...
Uncomplicated alcoholics, those with chronic Wernicke's encephalopathy (WE), and Korsakoff psychosis showed significant neuronal loss in the frontal cortex, white matter, hippocampus, and basal forebrain. [14] Uncomplicated alcoholics were seen to have a shrinkage in raphe neurons, the mamillary bodies, and the thalamus. [14]
Wernicke encephalopathy: an acute neurological syndrome of ophthalmoparesis, ataxia, and encephalopathy brought on by thiamine deficiency. Wernicke–Korsakoff syndrome , also called Korsakoff psychosis : a subacute dementia syndrome, often following Wernicke encephalopathy, characterized clinically by confabulation and clinicopathologically ...
Carl (or Karl) [a] Wernicke (/ ˈ v ɛər n ɪ k ə /; German: [ˈvɛɐ̯nɪkə]; 15 May 1848 – 15 June 1905) was a German physician, anatomist, psychiatrist and neuropathologist.He is known for his influential research into the pathological effects of specific forms of encephalopathy and also the study of receptive aphasia, both of which are commonly associated with Wernicke's name and ...
