Insomnia: Comorbidities from the Field of Sleep Medicine and Psychiatry in a Sample of an Interdisciplinary Center for Sleep Medicine

Abstract

In this study comorbidity of insomnia and other relevant diagnoses from the field of sleep medicine and psychiatry was analysed. For this purpose relevant diagnoses from physician´s letters of an interdisciplinary department of sleep medicine were documented in a sample of 102 patients with insomnia. Insomnia showed the highest comorbidity with depressive disorders (50%) followed by sleep related breathing disorders (17.6 – 37.3%) and sleep related movement disorders (12.7 – 21.5%). In case of subjectively reported insomnia symptom-atology this result indicates a profound diagnostic investigation with polysomnographic sleep recording and psychiatric exploration as a matter of clinical routine.
