First seen Jun 27, 2026 · Last updated Jul 01, 2026 · Updated 3 times
Summary
This study looks at how HIV and substance use disorder (SUD) affect the sense of smell and decision-making. Researchers will test 120 adults aged 18–65, including people with HIV, SUD, both, or neither. Participants will complete smell tests and computer tasks over two visits, and some may have a brain scan. The goal is to understand how these conditions impact brain function, not to provide treatment.
