What this trial studies

This observational study aims to assess the long-term impact of mood disorders, including depression and bipolar disorder, on participants who have previously engaged in research at the National Institute of Mental Health. Participants will complete online surveys and telephone assessments to evaluate their current mental health symptoms and treatments. The study will utilize existing clinical, biological, and neuroimaging data to identify predictors of long-term depressive symptoms, suicide attempts, and ketamine utilization. Additionally, it aims to track the incidence of premature death, including suicide, through linkage to national data sources.

Good fit: Ideal candidates are adults aged 18 and older who previously consented to participate in a related protocol over a year ago.

Not a fit: Patients who have not previously participated in the related protocol or are under 18 years old may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide valuable insights into the long-term management and treatment of mood disorders, potentially improving patient outcomes.

How similar studies have performed: Other studies have successfully utilized long-term observational approaches to understand mood disorders, making this a continuation of established research methodologies.
