[Age and clinico-pathogenetic correlations in acute cerebrovascular lesions].

A clinico-pathological analysis of 390 cases demonstrated that the clinico-pathogenetical traits of acute cerebrovascular lesions in individuals of different age groups permitted to distinguish in the group of acute cerebral dyshemia 2 nosological variants: acute disorders of cerebral circulation in the young and acute disorders of cerebral circulation in the elderly. In the young age group there is a prevalence of hemorrhagic processes, in the elderly-- ischemic lesions. An aggravating factor influencing the outcome in the younger group is the development of secondary liquid and cerebral hemocirculatory disorders, while in the other group--early appearing somatic disturbances. The important pathophysiological links due to which there may be clinical differences in the studied 2 groups are different types of the cerebral vasomotor function and the reactivity of the sino-aortal reflexogenic system.
