偏头痛是临床上最常见的原发性头痛,是一种慢性血管神经紊乱性疾病,表现为一侧或双侧发作性、搏动性剧烈头痛,临床主要分为以下类型:先兆型、无先兆型、视网膜型、为偏头痛预兆的儿童周期综合征、偏头痛并发症及很有可能的偏头痛。迄今尚未完全清楚其发病机制。各国学者提出了多种学说,近年来主要有三种理论:一是血管源性学说,认为偏头痛发作与颅外血管扩张有关。二是神经元学说,认为偏

Migraine is the most common clinical primary headache, is a chronic vascular neurological disorder, manifested as one or both episodes, severe pulsatile pulsation, the clinical is divided into the following types: aura, without aura Retinal type, childhood syndrome that is a sign of migraine, migraine complications and most likely migraine. So far, its pathogenesis has not been fully understood. Various scholars put forward a variety of theories, in recent years, there are three main theories: First, vasculogenic theory, that the onset of migraine and extracranial vascular dilatation. Second, neuron theory, that partial
