title: An unusual case of episodic stupor.
abstract: We present a case of episodic stupor associated with a myriad of neuropyschiatric manifestations that baffled doctors until they were recognized as sleep attacks. Continuous monitoring and recognition of a cyclical pattern of symptoms and signs helped to uncover the underlying cause of a rapidly cycling bipolar disorder. The symptoms abated quickly and persistently when treated by olanzapine and lithium.
