Parasomnias

Parasomnias are undesirable physical activities that occur during sleep. These disorders have medically explainable causes and are usually treatable.

Symptoms

Types of parasomnia include: 
  • Sleepwalking (Somnambulism) is a series of complex behaviors that are initiated during slow wave sleep and result in walking while asleep. The onset typically occurs in children and can continue into adulthood. It is occasionally associated with injuries. 
  • Sleep terrors are characterized by a sudden arousal from slow wave sleep with a piercing scream or cry, along with inconsolable intense fear and confusion. Symptoms include a sudden episode of intense terror during sleep. The episodes usually occur within the first third of the night, and the person will not recall having the event when fully awake. These events are mostly seen in children but can also happen in adults. 
  • Nightmares ​
