Blood Test Could Spot Teen Depression Before Crisis Hits
88% Informative
McGill University researchers identified nine molecular markers in dried blood spots from depressed adolescents.
The study found these microRNAs distinguished teens with depression from healthy peers and predicted how severe their symptoms would become months later .
Unlike adult depression biomarkers, these molecules appear unique to adolescent brain development.
Dried blood spot technique preserves samples without refrigeration.
Blood-based depression screening remains years away from clinical practice, but this research provides a crucial foundation for developing objective tools to identify at-risk teens before crisis intervention becomes necessary.
Future research will also explore whether these biomarkers can track treatment response, potentially helping clinicians adjust therapies before symptoms worsen.
