[Automatic actions with amnesia induced by taking hypnotic drugs. Association with personal and familial history of somnambulism and epilepsy].

A family which combined sleep-walking drug-induced sleep-walking and epilepsy is reported. This co-morbidity suggest various mechanisms which could explain drug induced sleep-walking. We stated the hypothesis that these behaviors were epileptic states due to a mini-withdrawal syndrome. This mini-withdrawal including of course a rebound of anxiety and insomnia during the day, but also a pro-convulsivant effect.
