慢性经常性头痛(Chronic daily headache,CDH)是一种常见病,但是关于该病的确切发病率和其流行病学的资料却很少,大约有40％的头痛病人属于该病的范畴。人们曾用过许多名字来描述本病,如:慢性紧张性头痛、转移性偏头痛、间歇性偏头痛、复合性头痛综合征、慢性经常性头痛、进行性偏头痛,以及血管紧张性头痛等。而且到目前为止,国际头痛协会在分类中还未能将其作为一个独立的疾病。 Chronic daily headache (CDH) is a common disease, but the exact incidence of the disease and its epidemiological data is very small, about 40% of headache patients fall into the category of the disease. People have used many names to describe the condition, such as chronic tension headache, migraine migraine, intermittent migraine headache, complex headache syndrome, chronic recurrent headache, migraine headaches, and vasomotor headache . And so far, the International Headache Association has not yet been able to classify it as an independent disease.
