Distúrbios do sono em pacientes com transtorno depressivo

Abstract

To evaluate sleep disorder complaints in outpatients with depressive disorder from a general hospital. Methods: An observational, cross-sectional study was carried out with a study sample composed of 70 patients (44 women and 26 men) with diagnosis of depressive disorder, according to the DSM-IV criteria. The patients were interviewed and evaluated by the Identification Questionnaire, the Sleep Habits Questionnaire and the Beck Depression Inventory (BDI). Results: In this study, 50 (71.3%) patients had recurrence of sleep disorder complaints. Mean BDI score was 35.83+8.85, with significant differences between patients with (38.50+8.70) and without (29.60+7.80) recurrence (p<0.05) and among patients with 1, 2, 3 and >3 episodes (p<0.05). In this study, 49 (70%) patients had insomnia and 21 (30%) had subjective excessive sleepiness. Significant differences were observed between the mean duration in months of the sleep disorders (7.16+2.10) and the depressive disorder (6.12+1.90) (p<0.05). Discussion: In the study sample, recurrence of sleep disorder complaints was high and significantly associated with severe depression. Insomnia was prevalent and the mean duration of sleep disorders was higher in relation to depressive disorder
