Headache

　　頭痛

　　Headache is a pain in the head and neck region that may be either a disorder in its own right or a symptom of an underlying medical condition or disease. The medical term for headache is cephalalgia. Headaches are one of the most common and universal human ailments, described in the Bible as well as in medical writings from ancient Egypt, Babylonia, Greece, Rome, India, and China.

　　頭痛就是頭、頸部之疼痛，既可能是一種病癥，也可能是某種潛在醫(yī)療問題或疾病的癥狀。頭痛的醫(yī)學術語為cephalagia。頭痛是人類最常見、最普遍的不適之一，在圣經(jīng)及古代埃及、巴比倫、希臘、羅馬、印度和中國的醫(yī)書中都有描述。

　　Contemporary doctors divide headaches into two large categories, primary and secondary, according to guidelines established by the International Headache Society (IHS) in 1988 and revised for republication in 2004. Primary headaches are those that are not caused by an underlying medical condition. There are three types of primary headaches: migraine, cluster, and tension headaches. More than 90% of all headaches are primary headaches. Secondary headaches are caused by disease or medical condition; they account for fewer than 10% of all headaches. form m.cddzsc.cn

　　根據(jù)國際頭痛協(xié)會1988年制定、2004年修訂的指導文件，頭痛現(xiàn)分為兩大類：原發(fā)性頭痛和繼發(fā)性頭痛。原發(fā)性頭痛是并非由潛在疾病所致的頭痛，它又可以分為三小類：偏頭痛、叢集性頭痛和緊張性頭痛。90%以上的頭痛屬原發(fā)性。繼發(fā)性頭痛是由疾病或醫(yī)療問題引起的，所占比例不到全部頭痛的10%。
