Computed tomographic (CT) study of the brains of 357 elderly demented patients. Clinical usefulness of CT measurements of brain atrophy and its correlation with mental assessment

Abstract

It is well known that there is some limitation in the diagnostic effectiveness of brain computed tomography (CT) of dementia. Some investigators suggested certain correlation between brain atrophy and degree of psychological imparement in demented patients, but others did not agree with these suggestions. Authors have felt that the number of samples is very important in statistical analyses, thus they collected a great number of appropriate samples of dementia: that is, 59 of Alzheimer disease (AD), 120 of senile dementia of Alzheimer type (SDAT) and 178 of vascular dementia (VD), and compared these CT findings with those of 100 non-demented people. Firstly, we observed no relation between aging and brain atrophy in any type of dementia while there was a certain relation in non-demented people. Secondly, the female brain could easily become atrophic physiologically and was more severely atrophic in case of dementia compared with the male brain. Thirdly, it was impossible to differentiate SDAT from VD only by measuring values of dilatation of ventricles (maximum width of the third ventricle and cella media index) and sylvian fissures (''sylvian index''). Finally, it was observed that there was deep relation between the results of clinical assessments and the degree of brain  More>>

Finally, it was observed that there was deep relation between the results of clinical assessments and the degree of brain atrophy in SDAT, because individual specificity in the type of atrophy was not variable in this type of dementia. Moreover all functions: that is, motor, intellectual, and emotional functions in SDAT patients, were impaired in the same degree respectively. From these results, authors could know many available characteristics of atrophy in the brains of demented patients through the following easy methods of measurement: linear measure method and ventricular-brain method, because we could analyse a sufficient number of samples.}
