| Abstract;In addition to conventional dementia rating scales, we used 41 items as a basis for estimating dementia symptoms under the aspects of disturbances of memory, orientation, integrative cognition including judgment and abstract, language, visuospatial ability, and personality. In order to elucidate the latent structure of dementia symptoms, we analyzed the data obtained through the above-described items in 82 mildly to moderately demented patients with primary degenerative dementias(PDD), the groups mainly included patients with clinically diagnosed dementia of the Alzheimer's type(DAT). The correlations of the answers to the items were then analyzed using a contingency coefficient, and nine clusters of symptoms were thus obtained using a factor analysis (principal component analysis) based on the correlation coefficients. As a result, the symptom clusters of memory (recent memory and remote memory), language (naming and visual language of writing and reading), integrative cognition composed of judgment, calculation, attention, and personality were identified as symptoms of DAT.
