Understanding how the brain processes rewards in depression

Reward Processing and Depressive Subtypes: Identifying Neural Biotypes Related to Suicide Risk, Resilience, and Treatment Response

Observational San Francisco Veterans Affairs Medical Center · NCT06080646

This study looks at how the brains of people with depression respond to rewards compared to those without depression to see what might be causing their difficulties in feeling rewarded.

What this trial studies

This observational study investigates the neurobiological mechanisms underlying reward processing deficits in individuals with major depressive disorder (MDD). By utilizing a combination of fMRI, EEG, and behavioral assessments, the study aims to characterize how the brain anticipates and evaluates rewards, and how these processes relate to clinical features of depression, including suicidality. The research will compare brain responses to reward anticipation between individuals with MDD and healthy controls, providing insights into the neurobiological variation that contributes to different clinical manifestations of depression.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18-70 diagnosed with major depressive disorder or healthy individuals for comparison.

Not a fit: Patients with past or present neurological problems or significant medical conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to the identification of biomarkers that improve the classification and treatment of depression.

How similar studies have performed: Other studies have shown promise in understanding reward processing in depression, but this specific approach is novel in its comprehensive multi-measure methodology.

Exclusion Criteria:

* Past or present neurological problems (including seizures and head trauma resulting in neurological or cognitive symptoms)
* Loss of consciousness (LOC) greater than 30 minutes or any LOC with neurologic symptoms
