title: [Parasomnia].
abstract: In elderly people, various abnomal behaviors could be accompanied during the sleep or around the bed time. There are many opportunities to receive consultation in a general or liaison psychiatry for diagnosis and treatment to these problems. REM sleep behavior disorder (RBD) is higher prevalence part of parasomnia at elderly people. Especially, RED has received a lot of attention in recent years from the relevance with α-synucleinopathy. On the other hand, new onset of non-REM parasomnia is lower frequency at the point of elderly people, however, it is important to understand the clinical features about parasomnias for differentiation from epilepsy and delirium.
