Two major causes of dementia in the elderly are reported to be the degeneration of brain and cerebrovascular diseases. Recently, CT findings of cerebrovascular diseases and brain atrophy have been noticed, because they rather clearly show these changes. The authors examined the view of atrophy frequently observed on the dementia in the elderly. The results obtained are as follows : 1) In accordance with the increase of age the appearance of the view of atrophy increased in frequency and that of extreme brain atrophy also increased. 2) As the age increased, the average value of the width of the IIIrd ventricle tended to increase. 3) In the cases accompanied with the view of cerebrovascular diseases remarkable ventricular dilatation was frequently observed, and in the very old dilatations of cerebral sulci, central fissure and Sylvian fissure were observed of all cases. 4) Of the group of severe dementia the view of extreme brain atrophy was observed in the major. However, there was no significant difference on the lesion of atrophy between the cases. The results mentioned above include some exceptional points respectively, so further investigation will be necessary from the qualitative and quantitative points of view.
