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.
对121例有脑血管供血不足早期迹象的患者进行的脑循环研究显示，典型的不对称性减慢始于脑血管床的远端部分，并在椎基底循环中占主导地位。尽管情绪、精神和体力活动的血流动力学需求未完全得到满足，但循环的自动调节功能得以保留。初始的循环障碍性脑病涉及血液动力学改变的泛化，以及沿颈内动脉的循环逐渐减慢。在这种情况下，自动调节功能在脑血管反应性受抑制时受到干扰。
