TREMOR

This study follows 1000 people with movement disorders like Parkinson's disease, essential tremor, and dystonia who receive an Abbott deep brain stimulation (DBS) system. Researchers will measure changes in movement symptoms and track any serious side effects for up to 5 years. T…

This study tests if a precise radiation treatment called stereotactic radiosurgery can reduce tremors and improve quality of life for people with essential tremor or Parkinson's disease whose medications aren't working well enough. About 60 adults will receive the treatment and t…

This study looks at how the brain functions differently in people with laryngeal dystonia (a voice muscle spasm condition) and voice tremor (a shaking voice). Researchers will use brain scans like MRI and EEG to compare patients and healthy volunteers. The goal is to better under…

This study aims to find out how common functional neurological disorders are in people who already have a movement disorder like Parkinson's disease, tremor, or dystonia. Researchers will examine 216 adults aged 18 to 80 using neurological exams, thinking tests, and questionnaire…

This study aims to collect information from people with movement disorders (like tremors or Parkinson's disease) and their family members. Participants will have one visit at the NIH clinic for exams, tests, and questions. No new treatments are given, but the data will help resea…

This study aims to better understand and classify different types of voice problems in people with laryngeal dystonia and voice tremor. Researchers will use voice tests and movement analysis to identify distinct symptom patterns. The goal is to improve diagnosis and guide future …

This study is collecting information from 4500 people who need brain surgery for conditions like aneurysms, tumors, epilepsy, and Parkinson's disease. The goal is to find out what factors help predict how well someone will recover after surgery. By standardizing how outcomes are …

This study follows 20 people with Parkinson's disease who have a brain procedure called focused ultrasound to stop tremors. Researchers want to understand why some people's tremors come back within two years. Participants will have brain scans and regular check-ups to find clues …

This study looks at how deep brain stimulation (DBS) — a treatment already used for movement disorders — affects voice and speech in people with laryngeal dystonia or voice tremor. Researchers will record brain signals during surgery and measure voice changes afterward. The goal …
