Classic migraine appears to be due to a primary focal change in cerebral neuronal metabolism associated with a spreading reduction in cerebral blood flow. Abnormalities of platelets and certain vasoactive amines have been found but we are still a long way from understanding the pathogenesis of migraine.
典型偏头痛似乎是由于与脑血流扩散性减少相关的脑神经元代谢原发性局灶性改变所致。虽然已经发现血小板和某些血管活性胺存在异常,但我们距离了解偏头痛的发病机制仍有很长的路要走。
