title: [Episodic paroxysmal hemicrania with seasonal waxing and waning pattern].
abstract: The chronic form of paroxysmal hemicrania was defined first. Although the episodic form was thought to be inevitably chronic, in time, episodic forms that never reach the chronic phase were identified. The supposed incidence of paroxysmal hemicrania is 1/50.000, and the ratio of the episodic to chronic form is 1:4. A seasonal type of episodic form, which is limited to three cases in the literature, has also been reported. In this article, a case who remained episodic for 40 years with seasonal waxing and waning attack variations is reported.
