Hemicrania Continua: Attacks May Alternate Sides

Authors


Abstract

SYNOPSIS

Hemicrania continua (HC) is characterized by a continuous unilateral headache of moderate severity, occurring in 2 patterns; a continuous form in which headaches persist continuously without remission for years, and a remitting form, consisting of headache phases separated by periods of pain-free remission. The remitting form of HC must be distinguished from other cyclical headache disorders such as episodic paroxysmal hemicrania and episodic cluster headache. Characteristically, the headache of HC is unilateral and without sideshift. We now report a case of HC in which headaches alternate sides.
