Abstract
-
Exploding head syndrome (EHS) is characterized by a sudden loud imagined noise or sense of a violent explosion in the head occurring as the patient is falling asleep or waking during the night. EHS is classified as "other parasomnia" on the ICSD-2 (International Classification of Sleep Disorders), and the neurophysiologic mechanisms underlying this hypnagogic phenomenon are unknown. EHS is a rare type of other parasomnia that has not been reported in Korea. We report two cases of EHS that presented with typical clinical symptoms.
