BRAIN DISEASE

This study looks at whether adjusting deep brain stimulation (DBS) can improve movement, speech, and swallowing in people already implanted with DBS for conditions like tremor, stroke, or traumatic brain injury. Researchers will test hand dexterity, grip strength, facial movement…

This study looks at how social and lifestyle factors—like education, race, and income—affect a person's thinking and memory after a stroke. Researchers will interview 450 adults who had a stroke and review their brain scans and medical records. The goal is to understand why some …

This study aims to learn more about how infections and inflammation harm the brain and nerves. Researchers will collect samples and perform tests on people aged 2 and older who have or may have these conditions. The goal is to better understand these diseases so that better tests…

This study is for adults 18 and older who have had a stroke or a transient ischemic attack (TIA), often called a mini-stroke. The goal is to collect information from standard medical tests and some extra research tests, like blood draws and brain scans, to better understand how t…

This study uses a robotic arm and brain stimulation to learn how different brain areas control reaching movements in people who have had a stroke and those who haven't. Researchers will measure movement paths, speeds, and accuracy. The goal is to understand brain changes after st…

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

This study follows 150 people with early-stage Parkinson's disease to see if the condition starts in the brain or the body first. Researchers will track symptoms like walking problems and thinking changes over 5 years using tests, scans, and questionnaires. The goal is to better …

This study follows 213 adults recovering from a first ischemic stroke to see if the intensity of inpatient rehabilitation (high vs. moderate) affects their functional recovery at six months. It also compares people whose stroke was linked to atrial fibrillation with those whose s…
