Abstract
Records of the emergency medical admissions to a large teaching hospital over a one year period were examined for evidence of Wernicke''s encephalopathy or Korsakoff''s syndrome. It was found that only 0.4% of the population studied had the classical triad of Wernicke''s encephalopathy, namely confusion, ophthalmoplegia, and ataxia. If two of these three criteria are allowed in the absence of other causes then 2.2% of the population had this limited Wernicke''s encephalopathy of Korsakoff''s syndrome. It is concluded that thae diagnosis of Wernicke''s encephalopathy should not rely on the presence of all three criteria; any two of the three in the absence of other causes will suffice for the diagnosis.
