At #ACNP2026? Come see my poster (W45, 5–7 pm)! We @erika-forbes.bsky.social find that immune activation and basal ganglia dopamine availability interact and relate to anhedonia among youth w/ depression, with evidence for anticipatory and not consummatory anhedonia. Preprint is now available!
Basal Ganglia Dopamine Availability and Immune Activation Interact and Relate to Anhedonia Severity among Youth with Depression
Anhedonia emerges in adolescence, has putative substrates in neural reward and dopamine systems, and is a hallmark of poor course in depression. Psychoneuroimmunology models suggest altered immune and...
