Adolescents who are at risk for later episodes of major depressive disorders differ from their peers who are not at risk on multiple measures of rapid eye movement (REM) and hypothalamic-pituitary-adrenal (HPA) activity during sleep, according to a study by Uma Rao and colleagues that appeared this fall in Neuropsychopharmacology . Early depressive episodes that occur during adolescence are strongly associated with other later problems in other areas such as interpersonal relationships, pregnancy, educational attainment, employment, and suicidal behavior; finding predictors of later problems is important for primary and secondary prevention.
Rao and colleagues compared youths at risk for major depressive disorder with peers using electroencephalographic (EEG) and HPA measures. They then followed the youths for 5 years and correlated their EEG and HPA measures with the chances of later episodes of depression. Here’s the abstract:
