Separating cognitive impairment in neurologically asymptomatic alcoholism from Wernicke-Korsakoff syndrome: is the neuropsychological distinction justified?
Psychological Bulletin | Published : 1990
Recent studies that have combined neuropathological data and clinical histories in a retrospective fashion have shown that Wernicke-Korsakoff neuropathology is often unsuspected antemortem and that, in terms of clinical presentation, it is more heterogeneous than previously assumed. Thus, many studies of neurologically normal alcoholics may have been confounded by the inclusion of patients with neurologically asymptomatic Wernicke-Korsakoff neuropathology. Postmortem and in vivo studies have shown that alcoholics, irrespective of neurological diagnosis, have widespread pathology involving many cortical and subcortical sites. In addition, clinical studies have indicated that, like neurologica..View full abstract
