Blood Test Identifies Depression Risk in Teenagers

Summary: Researchers have identified nine blood-based microRNAs that are elevated in teens diagnosed with depression, offering a potential biomarker for early detection. These molecules, absent in adult depression, may signal unique biological processes in adolescents. The study used a minimally invasive method involving dried blood spots, making it practical for broader screening applications. This breakthrough could lead to more objective, early diagnosis of teen depression, before symptoms be...
