Who could benefit from this research

Could help

Adults with major depressive disorder or significant anhedonia who are willing to participate in longitudinal studies and blood/brain imaging.

Less likely to help

People who cannot participate in follow-up visits or MRI studies may not benefit from this research.

What this research studies

This project looks at adults with affective disorders to understand whether immune activity and changes in the blood-brain barrier contribute to how severe depression and anhedonia are. It uses clinical assessments, blood tests, and brain connectivity measures to connect immune markers with brain function related to reward. The study follows participants over about three months to see how these factors change together and with symptoms. If the findings hold, they could point to new ways of diagnosing and tailoring treatments for depression.

Why it matters

Potential benefit: It could lead to new ways to diagnose subtypes of depression and guide targeted treatments.

How similar studies have gone: Previous work suggests links between peripheral immune signals and brain function in mood disorders, but this project aims to map dynamics over time.
