title: [Computerized tomography approaches in the study of dementia].
abstract: Computed tomography was used to study the prevalence rates of various types of intracranial pathology, hydrocephalus (HDC) and cortical atrophy (CA) in patients with late dementia (LD) and to comparatively assess the informative value of tomographic methods of cerebral morphometry. Computed tomographic data were obtained from 432 patients with LD. Despite the type of dementia, the authors revealed intracranial abnormalities of various etiology in 24.5%, postischemic foci being prevalent. Tumors, arachnoidal cysts, and chronic subdural hematomas were more infrequently diagnosed (in 2.6% of cases). HDC and CA were detected in 81.5 and 82.2% of patients with LD, respectively.
