A magnetic resonance imaging study of 19 alcoholic Korsakoff patients, 17 non-amnesic alcoholics and 23 non-alcoholic controls was undertaken. Several measures of ventricular size and interhemispheric area were significantly greater in the Korsakoff patients. Interhemispheric fissure size was greater in the non-amnesic alcoholics than the non-alcoholic controls. Cortical grey matter T1 values were essentially the same for the three groups, whereas the deep grey and the white matter T1 values for the Korsakoff patients were significantly greater than the non-alcoholic controls. These results indicate widespread cerebral atrophy in alcoholic Korsakoff patients, which is largely subcortical and does not develop independently of the diencephalic pathology. Alcoholic dementia may be a more severe form of alcoholic Korsakoff syndrome, aetiologically related to the nutritionally-induced diencephalic pathology, rather than the neurotoxic effects of alcohol on the cortex.
