The University of Alabama at Birmingham (UAB) has been awarded a $733,355 Project Grant from the National Institute of Mental Health (NIMH) under the Mental Health Research Grants (CFDA 93.242) program. The grant, titled "Evaluating Social Brain Health in HIV: An RDoC-Based Approach," aims to investigate the neural circuits and performance related to two core social cognitive constructs - perceiving social cues and understanding others - in people with HIV. Using well-validated paradigms and state-of-the-art fMRI tools, the project will examine the relationships between social cognition, neurocognition, and social functioning in this population. By systematically evaluating this hypothesis using an RDoC-based approach, the findings are expected to offer mechanistic insights into HIV-associated CNS complications, inform the heterogeneity of neurocognitive impairments, and identify novel treatment targets to improve brain health and quality of life for people with HIV. The grant period runs from March 1, 2025, to January 31, 2030.
