Abstract
Samples of 12 hospitalized Korsakoff patients, 12 hospitalized non-Korsakoff alcoholics and 12 controls all groups being of comparable age range, were tested using a set of 7 visual and olfactory measures which involved memory. By stepwise multiple discriminant analysis it was shown that strong separation could be effected between the 3 groups, solely on the basis of the olfactory recognition and recall tests, which included the Campbell-Gregson procedure. The use of anosmia as a diagnostic indicator for Korsakoff''s syndrome is discussed.
