Brain changes behind thinking and movement problems in older people with HIV and Parkinson's

Neurofunctional Mechanisms of Changes in Cognition and Motor Function in Aging with HIV and Parkinson's Disease

NIH-funded research Sri International · NIH-11312578

This project looks at brain changes that may explain why older people living with HIV sometimes have thinking and movement problems similar to Parkinson's.

What this research studies

You would be asked to have brain scans, movement testing, and thinking/memory tests while researchers compare people aging with HIV to people with Parkinson's disease. The team will focus on brain pathways between the basal ganglia and limbic system and measure slowing of thought and movement (bradyphrenia and bradykinesia). Participants will be followed over time to see how imaging signals relate to changes in behavior and function. Findings will be used to identify patterns that might predict decline or guide future treatments.

Who could benefit from this research

Good fit: Ideal candidates are adults (typically over age 50) living with HIV who notice memory, thinking, or movement changes, and people with Parkinson's disease enrolled for comparison.

Not a fit: People without HIV or Parkinson's, younger individuals without cognitive or movement symptoms, or those unwilling to undergo imaging and follow-up visits are unlikely to directly benefit from this project.

Why it matters

Potential benefit: If successful, this work could help doctors detect and treat thinking and movement problems earlier in older adults living with HIV.

How similar studies have performed: Previous brain imaging work has linked basal ganglia and limbic changes to cognitive and motor symptoms, but combining aging HIV and Parkinson's features in the same project is relatively novel.
