Clinico-tomographical aspects in the pathogenesis of vascular dementia

This article discusses the role of some pathogenetical factors in the main morphological variants of vascular dementia and their correlation with certain clinical parameters. On the basis of computer-tomographical (CT) studies of 62 patients with dementia, it was possible to distinguish three groups of patients, according to the type of parenchymatous brain lesions: (1) 14 patients with "pure" leukoaraiosis (LA); (2) 23 patients with ischemic foci (IF), and (3) 25 patients with a combination of LA and IF. A comparative study of these groups confirmed the concept that in the development of LA and dementia related to it, a special role is being attributed to such factors as arterial hypertension and aging.
