Who could benefit from this research

Could help

Individuals with Huntington’s disease or known HD gene expansion who participate in neuroimaging and clinical assessments.

Less likely to help

People without HD or without the ability to undergo MRI scanning or longitudinal assessments may not benefit.

What this research studies

Researchers will explore how brain blood flow and vessel function relate to brain damage and clinical symptoms in people with Huntington’s disease. They will use clinical assessments and brain imaging to map regional blood flow and vascular reactivity, and see how these relate to brain atrophy over time. The project aims to identify vascular mechanisms that could be targeted in future HD treatments. The findings could help explain why some patients progress differently and inform future clinical trials.

Why it matters

Potential benefit: If successful, the study could point to new vascular targets to slow HD progression and improve patient care.

How similar studies have gone: Previous work suggests neurovascular changes are linked to neurodegeneration, but this study seeks to clarify their role specifically in HD.
