Treatment of coexistent night-terrors and somnambulism in adults with imipramine and diazepam.

Abstract

Night-terrors and somnambulism are comparatively rare in adults and are most often associated with stage 4 sleep, especially delta activity. Although the data are limited, reports suggest that imipramine, which may control nocturnal enuresis, a stage 4 sleep disorder, and diazepam, which suppresses stage 4 sleep, may effectively treat the condition. This paper describes two patients with night-terrors and somnambulism who responded to imipramine but not to diazepam. Possible mechanisms of diazepam and imipramine, including effects on stage 4 sleep and pervasive anxiolytic actions, are discussed.
