Aims: To investigate a possible relationship between cerebellar glucose metabolism and recovery from ataxia in the first months of acute Wernicke-Korsakoff syndrome. Methods: Two cases of alcoholic Wernicke-Korsakoff syndrome were followed up with the clinical status and cerebral glucose metabolism over a 4- and 9-month period. Results: Initially both patients showed severe ataxia and elevated cerebellar glucose metabolism that decreased corresponding to the restitution of stance and gait. Conclusion: Increased cerebellar glucose metabolism at the onset of the illness may reflect the reorganization process of disturbed motor skills and may indicate cerebellar plasticity.
