The purpose of this study was to test differentiation of memory deficit in Alzheimer's disease group and depressive disorder group. Subjects were 24 mild Alzheimer-type dementia patiens(AD), 27 major depressive disorder patients(DEP), and 40 normal control group(NC). Finally 62 subject's output was analyzed. The memory test(K-MAS) was administered to 3 groups, all matched for sex, age, and educational level. AD group performed significantly worse than DEP, NC in most subtests of K-MAS. AD group showed (1) low total recall/recognition, (2) rapid rate of forgetting, (3) large numbers of intrusion, (4) recency part of serial position in free recall, (5) absence of practice effects. Discrimination analysis demonstrated 87.5% of diagnosis precision rate. Also, it was confirmed that Verbal Span test, Visual Span test, Delayed List Recall test, and Visual recognition have high discriminating power.
