NCT ID: NCT03042962 Completed - Spasmodic Dysphonia Clinical Trials

Brain Networks in Dystonia

Start date: August 1, 2015
Phase:
Study type: Observational

Task-specific focal dystonias are characterized by selective activation of dystonic movements during performance of highly learned motor tasks, such as writing or playing a musical instrument. To date, there is only limited knowledge about the distinct neural abnormalities that lead to the development of task-specificity in focal dystonias, which affect similar muscle groups but result in different clinical manifestations, such as writer's cramp vs. pianist's dystonia or spasmodic dysphonia vs. singer's dystonia. Our goal is to dissect the pathophysiological mechanisms underlying the phenomenon of task specificity in isolated focal dystonias using multi-level brain network analysis in conjunction with neuropathological examination of postmortem brain tissue from patients with dystonia. Rather than viewing these disorders as interesting curiosities, understanding the biology of task-specific activation of motor programs is central to understanding dystonia.
