Rhythm Sleep Disorders General criteria for circadian rhythm sleep disorders There is a persistent or recurrent pattern of sleep disturbance due primarily to one of the following Alterations of the circadian time keeping system. The human body has a master circadian clock in a control center of the brain known as the suprachiasmatic nucleus SCN This internal clock regulates the timing of such body rhythms as temperature and hormone levels The primary circadian rhythm that t An Historical Introduction.
