How acetylcholine-producing brain cells in the striatum relate to adult-onset dystonia

The Role of Striatal Cholinergic Interneurons in Dystonia

NIH-funded research Washington University · NIH-11247572

Using a specialized PET scan and MRI, doctors will look at acetylcholine-related brain cells and networks in adults with focal dystonia to find common brain changes.

What this research studies

If you join, you would receive a PET scan with a new tracer ([18F]VAT) that highlights vesicular acetylcholine transporters, along with structural and resting-state functional MRI to map related brain networks. The team will compare imaging from people with different forms of adult-onset focal dystonia to see shared changes in striatal cholinergic interneurons. Animal and biochemical data will be used alongside the human imaging to help interpret findings. The researchers hope these imaging markers could later be used to test treatments that target acetylcholine systems.

Who could benefit from this research

Good fit: Adults (generally 21+) with isolated adult-onset focal dystonia who can undergo PET and MRI scans are the best fit for this work.

Not a fit: People with childhood-onset or secondary dystonia, or those who cannot have PET/MRI scans, are unlikely to benefit from this project.

Why it matters

Potential benefit: If successful, this work could reveal a common brain target and imaging markers that help develop and test new treatments for adult-onset dystonia.

How similar studies have performed: Laboratory and animal studies have pointed to cholinergic interneuron involvement, but applying the new [18F]VAT PET tracer in people is relatively novel.
