What Causes a Person to Sleepwalk?

Several different factors may be involved in the development of sleepwalking. These may include genetics (traits that run in families), environmental, and medical conditions.

Sleepwalking is not associated with other sleep problems, sleeping alone in a room or with others, fear of the dark, or anger outbursts.

Genetics

Sleepwalking occurs more frequently in identical twins, and is 10 times more likely to occur if a first-degree relative has a history of sleepwalking. Therefore, it is thought the condition can be inherited.

Environmental Factors

Certain factors may cause a person to sleepwalk, such as:

Sleep deprivationChaotic sleep schedulesStressAlcohol intoxicationDrugs such as sedative/hypnotics (drugs that promote relaxation or sleep), neuroleptics (drugs used to treat psychosis), stimulants (drugs that increase activity), and antihistamines (drugs used to treat symptoms of allergy)

Medical Conditions

Medical conditions that have been linked to sleepwalking include:

Arrhythmias (abnormal heart rhythms)FeverGastroesophageal reflux (food or liquid regurgitating from the stomach up into the food pipe)Nighttime asthmaNighttime seizures (convulsions)Obstructive sleep apnea (condition in which breathing stops temporarily while sleeping)Psychiatric disorders, for example, posttraumatic stress disorder, panic attacks, or dissociative states, such as multiple personality disorder

it's funny, but I was just going to ask the forum this same question......b/c on the old  '' Threes Company "  show, Christie was sleepwalking, and it made me think of how my brother and my cousin  used to sleep walk and sleep talk . I mean they used to talk about non-sensical things while they were sleep walking

 They were both boys.

I am glad I never have to go into your closet.
