Quand et comment explorer une parasomnie?

The more striking result is that patients with a parasomnia, potentially or really violent (including acts of violence) and dangerous for the subject him or herself or for the bed partner or other people, will be recorded one or several times at hospital laboratory, then eventually at home. It is necessary to record parasomnia behaviour and experience or to record indirect EEG or polygraphic signs in favour of the type of parasomnia, Conversely, some parasomnias are easely diagnosed by the patient's story only. Finally, in some cases, polysomnographic recordings are realised to look for an associated disease or a simulation or to eliminate an other diagnostic.
