What is Sleepwalking?
Sleepwalking is a behavior disorder that originates during deep sleep and results in walking or performing other complex behaviors while asleep. It is much more common in children than adults and is more likely to occur if a person is sleep-deprived. Because a sleepwalker typically remains in deep sleep throughout the episode, he or she may be difficult to awaken and will probably not remember the sleepwalking incident. Sleepwalking usually involves more than just walking during sleep; it is a series of complex behaviors that are carried out while sleeping, the most obvious of which is walking. Symptoms of sleepwalking disorder range from simply sitting up in bed and looking around, to walking around the room or house, leaving the house, and even driving long distances. It is a common misconception that a sleepwalker should not be awakened. In fact, it can be quite dangerous not to wake a sleepwalker. The prevalence of sleepwalking in the general population is estimated to be between 1% and 15%. The onset or persistence of sleepwalking in adulthood is common and is usually not associated with any significant underlying psychiatric or psychological problems. Common triggers for sleepwalking include sleep deprivation, sedative agents (including alcohol), febrile illnesses, and certain medications. The prevalence of sleepwalking is much higher for children, especially those between the ages of three and seven, and occurs more often in children with sleep apnea. There is also a higher instance of sleepwalking among children who experience bedwetting. Sleep terrors are a related disorder and both tend to run in families.
