Rhythmic Movement Disorder
Video demonstrates head rocking movements in a 55-year-old woman with severe pulmonary sarcoidosis who was also diagnosed with obstructive sleep apnea and referred for a continuous positive airway pressure titration. During the study she was discovered to have these head rocking movements that arose out of N1 sleep. The results of her neurologic workup were normal. On subsequent history she mentioned that she has always rocked herself to sleep.
