With parasomnia what are my treatment options?

Usually no treatment. Most parasomnias are benign and require no particular treatment unless they become a danger to you or to other members of the household. For sleep walkers secure windows and doors, recommend sleeping on ground floors. If medications are needed, your sleep specialist will evaluate you and recommend appropriate treatment.
Depends on parsomnia. This depends on what the parasomnia is. Rem vs nrem. Walking/talking/eating/etc. Also this depends on whether medication may be causing it or even another sleep disorder. Seeing a sleep specialist can really help to tease this information out.
