title: Exploding head syndrome: a case report.
abstract: BACKGROUND
  Exploding head syndrome (EHS) is a rare parasomnia in which affected individuals awaken from sleep with the sensation of a loud bang. The etiology is unknown, but other conditions including primary and secondary headache disorders and nocturnal seizures need to be excluded.
  
  
  METHODS
  A 57-year-old Indian male presented with four separate episodes of awakening from sleep at night after hearing a flashing sound on the right side of his head over the last 2 years. These events were described 'as if there are explosions in my head'. A neurologic examination, imaging studies, and a polysomnogram ensued, and the results led to the diagnosis of EHS.
  
  
  CONCLUSIONS
  EHS is a benign, uncommon, predominately nocturnal disorder that is self-limited. No treatment is generally required. Reassurance to the patient is often all that is needed.
