title: [Characteristics of cerebrovascular circulation and its regulation in early stages of cerebrovascular disorders].
abstract: Cerebral circulation studied in 121 patients with early signs of cerebrovascular insufficiency exhibited typical asymmetric slowing down which started in distal compartments of the cerebral vascular bed and advanced to predominance in the vertebrobasilar circulation. Autoregulation of the circulation was preserved though hemodynamic requirements of emotional, mental and physical activity were not met completely. Initial discirculatory encephalopathy involves generalization of dysgemic shifts with progressive circulatory slowing down along the internal carotid arteries. In this case autoregulation gets disturbed in inhibited cerebrovascular reactivity.
