title: A school-refuser: his rest-activity rhythm involved multiple circadian components.
abstract: In a 950-day observation, a school- refuser showed a freerunning circadian rest-activity rhythm of 24.5 h interrupted intermittently by days of irregular rest-activity cycle. The interruption may be explained by an interaction between two desynchronized rhythmic components; one is freerunning and the other is of 24.0 h. The symptoms of emotional disorder were observed more frequently during days of interruption.
