title: Violent sleep-related behavior leading to subdural hemorrhage.
abstract: OBJECTIVE
  To polysomnographically determine, using split-screen electroencephalographic-video analysis, the cause of violent sleep-related activity in a patient whose differential diagnosis includes sleep walking (somnambulism), pavor incubus (adult night terrors), nocturnal seizures, psychogenic wandering, and rapid eye movement sleep behavior disorder.
  
  
  METHODS
  The patient was referred to the University of Iowa, Department of Neurology Sleep Disorders Center, Iowa City, from the local community to evaluate a history of violent dreams associated with injury. The subject presented with a subdural hemorrhage that was discovered with magnetic resonance imaging.
  
  
  RESULTS
  The diagnosis of rapid eye movement sleep behavior disorder was confirmed after a characteristic spell of violent behavior, with an associated dream, was captured polysomnographically.
