Advanced brain scans to understand thinking problems in people with HIV and cannabis use

Next-Generation MEG Imaging for Quantifying Cortical-Subcortical Dynamics in the Context of HIV and Cannabis Use

NIH-funded research Father Flanagan's Boys' Home · NIH-11321265

This project uses a new kind of brain scan (MEG) to look at how HIV and cannabis use affect brain circuits in adults living with HIV.

What this research studies

If you join, researchers will use a next-generation magnetoencephalography (MEG) scanner to record fast brain activity in adults with HIV, some who use cannabis and some who do not. They will compare brain circuit activity in cortical and subcortical regions while you perform thinking and memory tasks and during rest. The team will link those brain signals to cognitive test results and substance-use histories to search for measurable markers of HIV-related cognitive problems. Participation typically involves in-person visits for scans, cognitive testing, and questionnaires about health and substance use.

Who could benefit from this research

Good fit: Adults aged 21 or older who are living with HIV (with or without cannabis use) and are willing to have MEG scans, cognitive testing, and provide substance-use information.

Not a fit: People under 21, those without HIV, or individuals who cannot undergo MEG scanning (for example because of incompatible metal implants or inability to travel to the site) may not benefit or be eligible.

Why it matters

Potential benefit: This work could produce clearer brain-based tests to help diagnose and track cognitive problems in people living with HIV, including effects related to cannabis use.

How similar studies have performed: MEG has been useful in other neurological conditions, but using next-generation MEG specifically to study HIV-related cognitive changes and cannabis comorbidity is relatively new.
