Sleepwalking (Somnambulism)

go to bedSleepwalking is a sleep disorder that causes people to become active—usually by walking—while still asleep. The disorder is also called somnambulism and is especially common in children.

What Causes Sleepwalking?
Sleepwalking typically occurs during stages three and four–the deepest stages–of non-REM sleep. The causes of the disorder are not well understood, though it may have a genetic basis. Some children grow out of sleepwalking in adulthood, but the condition can also occur in adults. Fatigue, stress, alcohol use, sedatives, and some prescription drugs can increase a person’s risk of sleepwalking. Sleepwalking sometimes co-occurs with other conditions, including sleep apnea, bedwetting, and night terrors, though it is unclear if there is a correlation between these conditions and sleepwalking.

Symptoms of Sleepwalking
People who sleepwalk appear to be awake, with their eyes open. However, they do not respond to conversation and can be very difficult to wake up. Sleepwalkers may engage in a variety of activities ranging from eating, performing household chores, to attempting to drive a car. They may also engage in repetitive movements such as rubbing their eyes. Because people who sleepwalk often attempt to engage in normal daily activities while sleeping, sleepwalking can pose safety hazards.

Treatment for Sleepwalking
It is a myth that waking sleepwalkers is dangerous, but it can be very difficult to wake sleepwalkers, and they may be dazed after waking. Because sleepwalking is most common in children, who tend to grow out of it, doctors often do not treat it. However, tranquilizers can be helpful for some people who chronically sleepwalk. When sleepwalking occurs as a result of prescription sleep medications, most doctors recommend that people stop taking the prescription. The most important treatment for sleepwalkers involves taking safety precautions such as monitoring the sleepwalker to ensure he or she does not injure him/herself, blocking the stairs, and removing objects that a sleepwalker may trip over or use to harm him/herself.
