Wernicke-Korsakoff syndrome

 [ver´nĭ-kĕ kor´sah-kof€]
a disorder of the central nervous system, usually associated with chronic alcoholism and nutritional deficiency such as severe thiamine depletion. It is characterized by a combination of motor and sensory disturbances (wernicke's encephalopathy) and disordered memory function (korsakoff's syndrome). It typically has an abrupt onset, manifested by ocular motility, ataxia, diplopia, and horizontal nystagmus. Many patients are unaware of their unsteady gait, decreased mental acuity, and other signs of cognitive dysfunction.



There usually is an immediate improvement in ocular disturbances once therapy with thiamine is begun. The ataxia and diminished perceptual function and concept formation show a much slower rate of improvement. Only about 20 per cent of those with Korsakoff's syndrome fully recover. The mortality rate for the syndrome may be as high as 17 per cent during the acute phase. (See also alcoholism.)

Wernicke-Korsakoff syndrome

A late form of brain damage occurring in long-term alcoholics who rely mainly on alcohol for nutrition and who are severely deficient in the B vitamin thiamine. One form, Wernicke's encephalopathy, starts suddenly with incoordination, staggering, paralysis of eye movements and mental confusion progressing to stupor and death. Patients can be saved by a timely injection of a large dose of thiamine. The other form, Korsakoff's psychosis, features severe memory loss with inability to store new data and a process of confabulation, in which the affected person makes up stories to fill in the gaps in the memory. Korsakoff's psychosis is usually irreversible and proceeds to profound DEMENTIA. (Karl Wernicke, 1848–1904, German neurologist; and Sergei Sergeivitch Korsakov, 1853–1900, Russian psychiatrist and neurologist).

Wernicke-Korsakoff syndrome

A combination of symptoms, including eye-movement problems, tremors, and confusion, that is caused by a lack of the B vitamin thiamine and may be seen in alcoholics.
