1875年Brown-Sequard发现,脑部发生局部损害时,远离病灶的区域出现脑机能兴奋或抑制的紊乱现象。后来由von Monakow将这一现象命名为远隔机能障碍(diaschisis,DC)~([1]),或称神经机能联系不能。远隔机能障碍发生的确切机制尚未清楚,但可能与血流动力学改变、神经传导通路抑制、迟发型神经元死亡等因素有关~([2])。缺血脑卒中,除供血中心区局部脑血流及代谢均明显减低外,在远离病灶的部位 In 1875, Brown-Sequard found that when brain damage occurs locally, the disturbance or inhibition of brain function occurs in the areas far away from the lesion. Later, von Monakow named this phenomenon as diaschisis (DC) ~ ([1]), or called neurological failure. The exact mechanism of remote dysfunction is not yet clear, but may be related to changes in hemodynamics, inhibition of nerve conduction pathways, death of late-onset neurons and other factors ~ ([2]). Ischemic stroke, in addition to blood supply to the central part of the brain blood flow and metabolism were significantly reduced, the site away from the lesion
