몽유병은 수면수반증으로 분류되는데, 항우울제와 기타 향정신약물에 의해 이차적으로 유발될 수 있다는 보고들이 있었다. 그러나, NaSSA(noradrenergic and specific serotonergic antidepressant)계열인 mirtazapine에 의해 유발된 몽유병에 대한 보고가 없었다. 저자들은 우울증 환자에서 mirtazapine 사용에 의한 몽유병 1예를 경험하였기에 관련 문헌들을 고찰하고 보고하는 바이다.
Somnambulism is classified as a parasomnia and has been reported with the use of antidepressants and other psychotropics. However, to our knowledge, there have been no reports of somnambulism associated with the use of mirtazapine (a noradrenergic and specific serotonergic antidepressant；NaSSA). We experienced a case of the mirtazapine (30 mg/day)- induced somnambulism in a 65 year-old woman with major depressive disorder who has never been diagnosed as panic disorder, somnambulism, other parasomnias, neurological disorders (including epilepsy), and other medical diseases. The sleepwalking symptoms disappeared after the antidepressant was replaced with paroxetine (20 mg/day).
