Обзор
This study applies a hypothesis-driven approach to examine the effects of chronic marijuana use on HIV-associated inflammation and its subsequent impacts on central nervous system function, with the goal of identifying the mechanisms through which cannabinoids modulate neurological disorders and other comorbidities in persons with HIV.
Вмешательства
- Другое Multimodal, multi-parametric MRI
The investigators will use multimodal, multi-parametric sequences to investigate neuroinflammatory and neurodegenerative processes in vivo. Participants will be assessed three times over 2 years. - Другое Immune and cytokine profiling
Blood samples will be collected for immune and cytokine profiling. Participants will be assessed three times over 2 years. - Поведенческое Neuropsychological testing
Participants will have neuropsychological testing three times over 2 years.
