• Conditions: Suicide, Attempted; MDD; Depression; Major Depressive Disorder; Suicidal Ideas; Depression, Teen; Suicide; Depression and Suicide; Depression in Adolescence
• Interventions: Genetic: Genetic testing

• Registration Number: NCT05437588
• Lead Sponsor: University of Alabama at Birmingham

Brief Summary

This study is dedicated to help identify biomarkers for depression and suicide. The purpose of the study is to better understand these links to improve medical and psychiatric care in the future. This research is also to test the effects of standard treatment of depression on improvement in depressive and suicidal behavior and on biomarkers (e.g. miRNA) for these disorders.
