What this research studies

You would give small blood samples that researchers will use to isolate neural-derived exosomes and read microRNA patterns found in the brain. The team will compare these microRNA signatures between teens with and without suicidal thoughts or attempts and track how the signals change after treatments, including medications like ketamine. The work builds on earlier adult findings showing similar brain and blood changes linked to suicidality and treatment response. Outcomes will be compared to clinical symptoms to see whether blood signatures map onto risk and improvement.

Who could benefit from this research

Good fit: Ideal candidates are adolescents and young adults with recent suicidal thoughts or a recent suicide attempt, and those beginning treatment for suicidal ideation.

Not a fit: Children much younger than adolescents or people without suicidal thoughts or behaviors are unlikely to gain direct benefit from this work.

Why it matters

Potential benefit: If successful, this could lead to a simple blood test to flag teens at higher suicide risk and help match them to treatments more likely to work.

How similar studies have performed: Preliminary adult studies showed similar brain and blood microRNA changes and treatment-linked shifts after ketamine, but using neural-derived exosomal microRNAs specifically in adolescents is relatively new.
