TREMOR

This study follows 1,000 people with Parkinson's disease, essential tremor, or dystonia who receive an Abbott deep brain stimulation (DBS) system. Researchers will measure changes in movement symptoms and track any serious side effects over five years. The goal is to confirm the …

This study looks at how stereotactic radiosurgery (a precise type of radiation) affects quality of life and tremor severity in people with essential tremor or Parkinson's tremor whose medications aren't enough. About 60 participants will fill out questionnaires and have their tre…

This study tests a new, non-invasive device that uses gentle electrical currents to stimulate the brain and reduce hand tremors in people with Parkinson's disease. The device is 'closed-loop,' meaning it reads your tremor and delivers stimulation in sync with it. The study will e…

This study aims to learn more about movement disorders like Parkinson's disease and tremors by observing and collecting data from affected individuals and their family members. Participants will undergo tests such as physical exams, blood work, and imaging scans during one or two…

This study follows 20 people with Parkinson's disease who have a brain procedure called focused ultrasound to stop tremors. Researchers want to find out why some people's tremors return within two years. Participants will have brain scans and tests before and after treatment to h…

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 participants with neurological exams, thinking tests, and questionnaires. The go…

This study is collecting information from 4,500 people who have had brain surgery for conditions like aneurysms, tumors, or epilepsy. The goal is to find out what factors help predict recovery, such as thinking skills and emotional health. By standardizing how outcomes are measur…

This study uses brain scans like MRI and EEG to find out what makes laryngeal dystonia and voice tremor different in the brain. Researchers will compare brain activity in people with these voice disorders and healthy volunteers. The goal is to better understand these conditions, …

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 …

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 …
