CEREBRAL VASOCONSTRICTIVE REACTIONS IN PA THOGENESIS OF DISCIRCULATORY ENCEPHALOPATHY

Cerebral vasoconstrictive reactions were analysed in 100 healthy men a nd 165 patients with atherosclerotic discirculatory encephalopathy (DE ) of stage I and II. The study was performed by means of functional lo ading tests such as antiorthostatic, hyperventilation, with psychoemot ional tension. Individuals with hyperconstrictive reactions were revea led bath among healthy persons and among the patients. These reactions manifested as cerebrovascular hypertonicity or decrease of cerebral b lood flow The frequency of hyperconstrictive reactions as well ins the ir registration by means of several functional tests such significantl y increased with DE progression.
