偏头痛发病率较高,约占普通人群的10％～20％。曾有几种假说试图解释偏头痛是由单一机理引起的,诸如血小板疾病、脑血管痉挛或中枢感受伤害障碍等,但都不能圆满地解释偏头痛的复杂临床特征及某些病理生理学改变,且慢性紧张型头痛又常常表现为偏头痛样发作。本文就新近提出的血管、脊髓上及肌筋膜感受伤害性信息传入的综合作用来解释偏头痛及紧张型头痛的发病机理。 Migraine incidence is higher, accounting for about 10% of the general population to 20%. There have been several hypotheses that attempt to explain that migraine is caused by a single mechanism such as platelet disease, cerebral vasospasm, or central sensory impairment but fail to satisfactorily account for the complex clinical features and some pathophysiological changes in migraine Chronic tension-type headaches often show migraine-like attacks. This article explains the pathogenesis of migraine and tension-type headache on the combined effects of newly introduced information on nociceptive, vascular and myofascial sensations.
