RESUMO
Background: Excessive daytime sleepiness (EDS) has been reported among depressed patients in many populations. Many depressed patients seek medical attention partly to deal with EDS; but this sleep disorder is often overlooked in clinical practice. Objectives: The objectives of this study were to determine the prevalence of EDS among depressed patients and determine its relationship with the severity of depression. Methods: Sixty-seven patients diagnosed with depressive episode took part in the study. The severity of depression was rated using the 17-item Hamilton Depression Rating Scale (HDRS). EDS was evaluated using the Epworth Sleepiness Scale (ESS). Results: The mean ESS score was 9.2 (SD=2.8). EDS; defined as an ESS score]10; was present in 44.8of the depressed patients. The mean score on the HDRS was 14.8 (SD=3.6); representing the mild-moderate depression range. ESS scores correlated highly and positively (r=0.69; p=0.000) with scores on the HDRS. Conclusion: In the light of the high prevalence of EDS among depressed patients and its undesirable consequences; it is suggested that daytime sleepiness be evaluated in depressed patients
