Brain-scan study of voice dystonia and tremor

This study looks at how the brain and voice system work in people with laryngeal dystonia or voice tremor, and compares them with healthy volunteers. The goal is to better describe different “types” (phenotypes) so future care can be more targeted.

This study looks at how genetics and brain patterns are connected to laryngeal dystonia and voice tremor, including people with certain types of voice disorders. You may be asked to do imaging and voice-related assessments to help researchers understand what’s causing these symptoms.

This trial uses brain scans to understand how brain networks work in people with focal dystonia, and to compare with family members and healthy volunteers. It may help researchers better understand what goes wrong in the brain and guide future treatments.

This study tests how a brain–computer interface reads brain signals to understand and possibly support people with a specific voice condition called adductor laryngeal dystonia. It also compares results with healthy people to help researchers see how brain activity differs during voice tasks.

This trial studies deep brain stimulation (a surgically placed device that sends electrical signals) to reduce voice tremor or laryngeal dystonia. You may be considered if your symptoms are persistent despite medication and you can complete the study tasks and pre-surgery testing.

This study tests whether a noninvasive brain stimulation treatment (referred to as neuromodulation, such as rTMS) can improve symptoms of laryngeal dystonia. It’s meant to see if stimulating certain brain areas can reduce how severely your voice/throat problem affects you.
