[The role of the reactivity of cerebral vessels in the diagnosis and treatment of circulatory encephalopathies].

The central and cerebral hemodynamics was studied in 47 patients with atherosclerotic discirculatory encephalopathy, grade 1-2. Functional challenges were used to characterize the metabolic, neurogenic and neurohumoral control mechanisms in cerebral circulation, revealing inadequate angiospastic reaction in the defined vascular beds. The data demonstrate the role of reactivity of the cerebral blood vessels in the pathogenesis of discirculatory encephalopathy, and hence the possibility of precise choice of the correcting treatment which conforms with the mechanisms of angiospastic disorders.
