Risk of Excessive Daytime Sleepiness Associated to Major Depression in Adolescents

Given the limited data currently available in the literature, the aim of this study was to investigate the risk of excessive daytime sleepiness (EDS) associated with major depression in a large sample of adolescents. The clinical and polysomnographic data of 105 adolescents recruited from the database of the Erasme Hospital sleep laboratory were analysed. A score > 10 on the Epworth Sleepiness Scale was used as cut-off for the diagnosis of EDS. The status (remitted or current) and the severity (mild to moderate or severe) of major depressive episodes were determined based on the diagnostic criteria of the DSM-IV-TR during a systematic psychiatric assessment. Logistic regression analyses were performed to determine the risk of EDS associated with major depression in adolescents. The prevalence of EDS was 34.3% in our sample of adolescents. After adjusting for the main confounding factors associated with EDS, multivariate logistic regression analysis demonstrated that unlike mild to moderate major depression, remitted major depression and severe major depression were risk factors for EDS in adolescents. In our study, we have highlighted that in adolescents, the EDS could be both residual symptom and severity marker of major depression, which seems to justify a systematic psychiatric assessment in adolescents with EDS complaints in order to allow better management of this problem in this particular subpopulation.SCOPUS: ar.j
