BRAIN DISEASE

This study looks at 60 people who already have a deep brain stimulation (DBS) device for movement problems like tremor, stroke, or brain injury. Researchers will adjust the device's settings and then test how well participants can move their hands, speak, swallow, and control fac…

This study tests whether temporarily stimulating a specific part of the brain can improve hand, arm, and speech function in people who had a stroke at least 6 months ago. Ten participants will have a thin wire placed in the brain for less than 30 days to deliver mild electrical p…

This study aims to better understand stroke and mini-strokes (TIAs) by observing up to 4,000 adults who have had or are at risk for these conditions. Researchers will collect data from standard medical tests and some extra research tests, like blood draws and brain scans, to trac…

This study aims to learn more about how infections and inflammation harm the brain and nervous system. Researchers will observe up to 1,000 people aged 2 and older who have or may have a nervous system infection or inflammation. By collecting samples and performing tests like MRI…

This study follows 213 adults who had a stroke caused by atrial fibrillation and are in inpatient rehab. Researchers want to see if patients with this type of stroke have different recovery needs and if more intense rehab (3-5 sessions daily) leads to better function at six month…

This study looks at why some people keep their thinking skills after a stroke while others don't. Researchers will interview 450 adults who had a stroke and had a brain scan. They want to see how things like education, race, and income affect memory and attention over time.

This study follows 150 people with early-stage Parkinson's disease to see how symptoms like walking problems and thinking changes differ between two newly identified types: 'brain-first' and 'body-first.' Researchers will use brain scans, movement tests, and other assessments ove…
