[Problems in CT diagnosis of the aging brain].

The different methods of measuring the intracranial CSF spaces on CT images are described. The values obtained are demonstrated to separate the normal aging brain from the brain in senile dementia of Alzheimer's type. The CT criteria for the diagnosis of multi-infarct dementia are shown. The significance of CT studies in senile depression is discussed. The problem of vascular encephalopathy (leuko-araiosis) in normal aging of the brain and in dementia is considered in particular, and even the occurrence of intracranial space-occupying lesions and normal pressure hydrocephalus, as treatable causes of dementia and depression, are mentioned. The data and results of my own CT research on normal brain aging, dementia and depression are presented with reference to the literature.
