Parasomnias refer to a wide range of disorders where people experience undesirable activities or movements during sleep. Some of the more common examples include sleep walking, sleep eating and bedwetting. With these issues, it is important to undergo a thorough evaluation for any possible contributing medical issues or side effects of a substance or medication. Depending on the primary cause of the parasomnia, symptoms can sometimes be improved with changes to sleep habits, but occasionally medications are needed. Sleep testing is usually recommended.
