[Headache in autonomic-vascular dystonia].

The clinical variants of headaches were observed in 83 patients with autonomic vascular dystonia. The diagnostic table was designed to differentiate between the latter and migraine. Bulbar conjunctiva and retinal microcirculation studies revealed multiple morphological and hemodynamic changes.

[Pathogenetic aspects of ischemic strokes].

The article presents data on total calibrometry of the vascular bed of the brain in 26 patients who had died of ischemic cerebral stroke. All patients with nonthrombotic ischemic cerebral stroke showed a considerable decrease in the total lumen of the cerebrovascular bed on the side of the ischemic focus with a significant increase in the coefficient of hemispherical asymmetry. In most cases impoverishment of the hemodynamics was related not to occlusive or gross stenosing process of one of the major vessels but rather to nonmanifest narrowing of several vessels in the hemisphere on the involved side.

[Clinical aspects and pathogenesis of the initial (precrisis) disorders of cerebral circulation].

In 82 patients from 20--35 years of age with vegetative-vascular dystonia the authors studied clinical variants of the disease, the bioelectrical brain activity, the state of cerebral circulation, the visual analyzer, the cardiovascular system, histamine, protein, lipid, carbohydrate metabolism and the state of coagulative blood system. In the majority of the cases the studies demonstrated hystaminemia, some shifts in the biochemical blood content, an increased brain vascular tone, a drop of blood repletion and disturbances of regional hemodynamics. The studies also depicted a decreased functional lability of the main cortical bioelectrical processes, disturbances of electric activity and propulsive possibilities of the myocardium.
