群発頭痛の診断－その他の頭痛との鑑別－

抄録

　Diagnosis of cluster headache is based on the characteristics, frequency, and duration of headache attacks; however, it can sometimes be challenging. Differential diagnosis from other TACs is sometimes required as there is some overlap. Differentiation from migraine can sometimes be difficult such as side-locked migraine or during periods of low frequency in a cluster period. Conditions such as cerebrovascular disorders or brain tumors may present similar symptoms requiring careful diagnosis particularly during the first cluster period.
