There are several causes of sleepwalking. For some people, it can be hereditary in nature. It has been seen that if parents or grandparents sleepwalked, then the possibility is very high that children and/or grandchildren will also sleepwalk. Sometimes high grade fever, chills and diseases can cause sleepwalking.
Hormonal imbalances are another common reason and also some physiological changes like puberty can cause sleepwalking.
There are some drugs and medications that can cause sleepwalking. When a person is sleeping, the sleep stages occur in a cyclical order where a person drifts from light sleep to deep sleep. Somewhere during these stages, the body releases a hormone which paralyzes the body and that is when a person drifts into deep sleep. In people, who have sleepwalking disorder, this hormone is absent and that is why they remain semiconscious through the night. It is in this semi-conscious state that these people tend to sleepwalk.
Sleepwalking is associated with sleep disorders and is caused mainly due to the lack of sleep. Some medications that can trigger this disorder are anti-stress medications, oxycontin, depression medications, and also medications for schizophrenia can cause sleepwalking. Most of the medications that are meant to calm the brain or affect it also cause sleep walking. In addition, any medication or a dosage of medication that interferes with the natural sleep pattern of a person can cause this disorder. If a person feels that after taking a certain medication, he has started sleep walking, he should talk to his doctor about the possibility of changing that medication.
