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]
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.
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 . [ 2 ]
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]
Thiamine deficiency is a medical condition of low levels of thiamine (vitamin B 1). [1] A severe and chronic form is known as beriberi. [1] [7] The name beriberi was possibly borrowed in the 18th century from the Sinhalese phrase බැරි බැරි (bæri bæri, “I cannot, I cannot”), owing to the weakness caused by the condition.
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.
Wernicke-Korsakov syndrome or Polioencephalitis haemorrhagica superior associated with Korsakov's psychosis: A condition characterized by nystagmus, ocular and Conjugate gaze palsy, ataxia and psychosis due to nutritional deficiency, more specifically of thiamine and observed mainly, though not exclusively, in alcoholics.
[33] This suggests that confabulation in these patients is "domain-specific." Korsakoff's patients who confabulate are more likely than healthy adults to falsely recognize distractor words, suggesting that false recognition is a "confabulatory behavior." Alzheimer's disease is a condition with both neurological and psychological ...
