| Outline of Final Research Achievements |
In this study, we investigated whether early diagnosis of mild AD and MCI are possible using VBM by MRI and Alzheimer's Disease Assessment Scale-cognitive component-Japanese version(ADAS-Jcog) accumulated in the database. The subjects are 330 patients who visited the clinic, 192 patients with mild AD and 138 patients with MCI. As the results of this study, there was significant difference between MCI and mild AD in degree of VOI atrophy, ratio of cerebral atrophy, ratio of VOI atrophy, atrophic rate. A significant difference was between MCI and mild AD in 10 of the 11 sub-items of ADAS-Jcog. Furthermore, as result of discriminant analysis by the stepwise method, the items necessary to distinguish between MCI and AD were proportion of whole ratio of cerebral atrophy, temporal orientation, word reproduction, reproduction ability, item designation. The discrimination rate was 80.9%. These five items were useful indicators for distinguishing between MCI and mild AD.
