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]
To help to prevent Wernicke syndrome, these individuals should be administered a multivitamin preparation with sufficient quantities of thiamine and folic acid. During alcohol withdrawal, the prophylactic administration of thiamine , folic acid , and pyridoxine intravenously is recommended before starting any carbohydrate-containing fluids or food.
Wernicke syndrome is an ambiguous term. It may refer to: Wernicke aphasia: the eponymous term for receptive or sensory aphasia.; Wernicke encephalopathy: an acute neurological syndrome of ophthalmoparesis, ataxia, and encephalopathy brought on by thiamine deficiency.
Korsakoff psychosis typically follows after the symptoms of Wernicke's decrease. [ 29 ] [ 30 ] Wernicke-Korsakoff syndrome is typically caused by conditions causing thiamine deficiency, such as chronic heavy alcohol use or by conditions that affect nutritional absorption, including colon cancer, eating disorders and gastric bypass.
Doses of 15-30 mL are typically administered three times a day; the result is aimed to be 3–5 soft stools a day, or (in some settings) a stool pH of <6.0. [4] [9] [10] [19] Lactulose may also be given by enema, especially if encephalopathy is severe. [19] More commonly, phosphate enemas are used. This may relieve constipation, one of the ...
