EEG Sleep in Adolescents With Major Depression: the Role of Suicidality and Inpatient Status

All night sleep EEG recordings were performed for 3 consecutive nights in 27 adolescents with a diagnosis of major depressive disorder (MDD) & 30 normal adolescent controls. Group comparisons revealed no significant diagnostic differences but analyses within subgroups for MDD adolescents revealed heterogeneity of EEG sleep findings in association with suicidality & inpatient status. Findings in this study suggest possible reasons for discrepancies in previous EEG sleep studies. (33 refs.)
