Exploring the link between childhood trauma and suicide risk through microRNA analysis

MicroRNA Correlates of Childhood Maltreatment and Suicidality

Observational University of Alabama at Birmingham · NCT04923685

This study is trying to see if certain genetic markers in people who experienced childhood trauma can help us understand their risk of suicidal thoughts and behaviors.

What this trial studies

This observational study investigates the relationship between childhood maltreatment and the risk of suicidality by analyzing microRNA levels in participants. It aims to identify specific neural-derived exosomal miRNAs that correlate with suicidal behavior in individuals with a history of childhood trauma. The study will also assess how acute stress affects miRNA expression in these individuals using the Trier Social Stress Test. By gathering genetic material from participants, the research seeks to uncover potential molecular signatures that could indicate suicide risk associated with childhood trauma.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18-60 who are physically healthy and either diagnosed with Major Depressive Disorder or have no history of mental illness.

Not a fit: Patients with a history of severe mental disorders, such as bipolar disorder or psychotic disorders, may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved understanding and identification of biomarkers for suicide risk in individuals with a history of childhood maltreatment.

How similar studies have performed: While the specific approach of analyzing microRNA in relation to childhood trauma and suicidality is novel, similar studies have shown promise in understanding the biological underpinnings of mental health conditions.
