title: [The constrictive reactions of the cerebral vessels in the pathogenesis of circulatory encephalopathy].
abstract: Cerebral vasoconstrictive reactions were analysed in 100 healthy men and 165 patients with atherosclerotic discirculatory encephalopathy (DE) of stage I and II. The study was performed by means of functional loading tests such as antiorthostatic, hyperventilation, with psychoemotional tension. Individuals with hyperconstrictive reactions were revealed both among healthy persons and among the patients. These reactions manifested as cerebrovascular hypertonicity or decrease of cerebral blood flow. The frequency of hyperconstrictive reactions as well as their registration by means of several functional tests such significantly increased with DE progression.
