  • Title: A feature of alcoholic Wernicke's encephalopathy favourable to the maintenance of memory function: vomiting.
    Author: Price J, Hicks M, Williams G.
    Journal: Alcohol Alcohol; 1993 May; 28(3):339-45. PubMed ID: 8352845.
    Abstract:
    Outcome in terms of progression of Korsakoff's psychosis is known to be unlikely when the preceding thiamin deficiency syndrome, Wernicke's encephalopathy, does not follow heavy alcohol use. There is evidence that alcohol potentiates thiamin-related brain damage. It is argued here that in heavy drinkers, if vomiting precedes the onset of the encephalopathy, then the latter might develop at a time when tissue alcohol levels are close to zero. Any progression to Korsakoff's psychosis could then be associated with less or even no impairment. This outcome would not be expected if ingestion of alcohol continued during the vomiting stage. In a follow-up study of 61 cases of alcoholic Wernicke's encephalopathy, these concepts are given some support by the results obtained.
