What this research studies

This project uses existing health and brain imaging data from large studies of adults (UK Biobank) and adolescents (ABCD) to explore why some people experience anhedonia. Researchers will apply a specialized MRI method (diffusion basis spectrum imaging) to search for signs of neuroinflammation in brain reward regions and compare those signals with blood inflammation markers and symptom reports. The team will examine both single-timepoint and follow-up data to see whether neuroinflammation helps explain changes in anhedonia over time. Because this is a secondary analysis of existing datasets, no new scans or clinic visits are being requested from patients.

Who could benefit from this research

Good fit: The most relevant people are adolescents and adults who experience low pleasure or motivation (anhedonia) and whose health or imaging data are included in large research databases.

Not a fit: People without symptoms of anhedonia or those looking for immediate clinical treatment would not directly benefit from this secondary-data project.

Why it matters

Potential benefit: If successful, this work could reveal inflammation-driven pathways behind anhedonia and point toward new treatment strategies.

How similar studies have performed: Previous research has linked blood inflammation to anhedonia, but imaging of brain inflammation—especially using longitudinal approaches—is relatively new and not yet widely confirmed.
