Episodic paroxysmal hemicrania (EPH) is a rare disorder characterized by discrete bouts of hemicranial headache separated by headache-free remissions. Although EPH resembles episodic cluster headache in thelocation and quality of pain as well as the pattern of associated autonomic features, it is distinguished by the greaterfrequency andshorter duration of individual headaches. Differentiation of thesc disorders is important because EPHalmost invariablyresponds to treatment with indomethacin but not to standard cluster headache therapy.
