The purpose of this study is to demonstrate that the phenotype of dystonia is associated with the degree of striatal ACh-I alterations.
In this molecular imaging study, the investigators will directly test this hypothesis using a PET radiotracer of the vesicular acetylcholine transporter (VAT). Their goal is to explore the relationships between cholinergic dysfunction and clinical disease expression and the associated morphological and functional alterations. The experimental protocol will also include multimodal MRI, MRI diffusion tensor (to study the microscopic structure of white matter) and functional MRI of the resting state (to study the functional organization of cerebral cholinergic networks at rest).
