From 4 months before the admission, he was noticed to have become short-tempered, and his behaviors were not appropriate for occasions. In parallel, his disability in performing social activities became obvious. The magnetic resonance imaging of his brain indicated marked frontotemporal atrophy and bilateral dilatation of the lateral ventricle as well as mild atrophy of other brain regions. By use of single photon emission computed tomography with ^<123>I-IMP, the regional cerebral blood flow was found to be markedly decreased in bilateral frontal lobes and the right temporal lobe. His condition severely deteriorated during a short period after the admission, showing symptoms such as disorientation, poor rapport with others, "stehende Redensart" (C. Schneider), and extinct initiative in thought, speech and behavior. Dysarthria and dysphagia appeared 7 months after the admission, which further deteriorated his condition, leading to his death due to respiratory failure within 9 months after the admission. This very acute course of deterioration seemed to be unusual for Pick's disease. Creutzfeldt-Jakob disease (CJD) was not feasible, because neither periodic synchronous discharges nor myoclonic movements were observed whereas "stehende Redensart", which is seldom seen in CJD patients, became outstanding. It was also difficult to define this case as dementia with motor neuron disease, because neither muscle atrophy nor fasciculation was notable. Although we infer that this case is closely related to the frontotemporal dementia (FTD) proposed by the Lund and Manchester group, the clinical and neuroimaging findings may not safely be attributed to this subgroup of dementia. Since little is known about non-Alzheimer degenerative dementia including FTD, further accumulation of dementia cases having clinical features inconsistent with known classifications is needed to understand dementia and to define subgroups., 17, KJ00002368568, P, 症例報告, Case Report}, pages = {117--122}, title = {分類が困難であった初老期痴呆の一例}, volume = {15}, year = {2002}, yomi = {ヤスタケ, チエ and トヨダ, ヒロタカ and カワシマ, フミオ and トヨダ, カツヒロ} }
