This early-phase study tests a new radioactive tracer called 11C-HY-2-15, designed to detect abnormal alpha-synuclein protein in the brain. Researchers will scan 70 adults with multiple system atrophy, Parkinson's disease, progressive supranuclear palsy, or healthy volunteers to …

This study tests whether a personalized form of transcranial magnetic stimulation (TMS) can improve motor and non-motor symptoms in people with Parkinson's disease, multiple system atrophy, or progressive supranuclear palsy. Fifty participants will receive 10 days of targeted TMS…

This study tests whether giving vitamin D3 locally and using a minor surgical technique called corticision can make orthodontic tooth movement faster. Sixteen patients aged 13-20 who need premolar extractions will be followed for 12 weeks. The goal is to see if these methods safe…

This study tests whether a non-invasive brain stimulation technique called tDCS, applied while people walk, can improve motor skills like gait, speech, and eye movements. Twenty adults with progressive supranuclear palsy, corticobasal degeneration, or Parkinson's disease will rec…

This study tests whether a mild electrical brain stimulation technique called tDCS can improve swallowing difficulties in people with Parkinson's disease. 58 participants will receive either real or sham tDCS alongside standard swallowing therapy. Researchers will measure changes…

This study screens 360 adults with neurodegenerative disorders like ALS, frontotemporal dementia, and progressive supranuclear palsy. Researchers will use medical history, physical exams, memory tests, movement analysis, MRI scans, and other tests to find common features and diff…

This study looks at whether new, quick tests that measure how fast people can move can help doctors diagnose brain diseases like Alzheimer's and predict recovery after a stroke. Researchers will test 129 adults aged 40-85 with stroke or memory problems. The goal is to see if thes…

This study uses special PET scans to measure tau protein buildup in the brains of 332 people with Progressive Supranuclear Palsy (PSP), a rare brain disorder that affects movement and balance. Researchers want to see how tau levels change over time and relate to symptoms. Partici…

This study follows nearly 3,000 people, including healthy adults and those with memory or movement problems, to learn how brain diseases like Alzheimer's and Parkinson's develop. Researchers use advanced brain scans and tests to track changes over time. The goal is to improve ear…

This study uses a new ultra-high-resolution PET scanner to take detailed pictures of the brain and spinal cord in 300 healthy volunteers and people with conditions like Alzheimer's, Parkinson's, ALS, and psychotic disorders. The goal is to understand how small brain regions chang…

This study aims to find early markers of Parkinson's disease, multiple system atrophy, and Lewy body dementia by analyzing samples from the nose, blood, and urine. Researchers will compare results from 180 people with these conditions and healthy volunteers. The goal is to improv…

This study is gathering information from 700 people with Parkinson's disease or similar conditions who experience freezing of gait—a sudden inability to move their feet while walking. Researchers will track symptoms, walking patterns, and falls over three years using questionnair…

This study aims to find genes that cause eye misalignment (strabismus) and related conditions involving the cranial nerves and brainstem. Researchers will analyze DNA from up to 20,000 participants with these disorders. The goal is to better understand the genetic causes, which c…

This study uses special brain scans to measure damage to nerve connections in people with Multiple System Atrophy (MSA) and Progressive Supranuclear Palsy (PSP). Researchers will scan 36 adults aged 45-80 to see how the disease changes over time. The goal is to better understand …

This study is testing whether artificial intelligence (AI) can analyze brain scans to help diagnose Parkinson's disease and related conditions like multiple system atrophy. Researchers will also see if the scans can predict how fast the disease will progress. The study involves 9…

This study collects information and samples from 1,000 people with or at risk for brain diseases like Alzheimer's, ALS, and frontotemporal degeneration. Researchers will track changes in thinking, language, and brain scans over time. The goal is to build a resource for future stu…
