Sleepwalking

I have a grandchild who walks in her sleep, wand I appreciated your comments about that. However, I also have an adult niece who sleepwalks. What about sleepwalking in adults? Has that been studied?

 Among other researchers, Dr. Dauvilliers, professor of physiology and neurology and director of the sleep lab at Gui-de-Chauliac Hospital in Montpellier, France, was principal investigator and author of a study on adult sleepwalking. In a nutshell, conclusions were that adult sleepwalking is a potentially serious condition that may induce violent behaviors and affect health-related quality of life. According to A. Kales in the British Journal of Psychology, sleepwalking and night terrors share a common genetic predisposition. Sleepwalking appears to be a more prevalent and less severe manifestation of night terrors. Inherited factors appear to predispose a person to develop sleepwalking or night terrors. However, how these traits are expressed may be influenced by factors in the person’s environment.
