This study collects DNA from up to 1,000 adults with progressive supranuclear palsy (PSP), corticobasal syndrome (CBS), multiple system atrophy (MSA), or related conditions, plus their family members. Researchers will sequence participants' whole genomes to find genetic variants …

This study enrolls family members of people with inherited ALS who do not yet have symptoms. Participants receive genetic counseling and testing, and are followed yearly to track when and how symptoms might appear. The goal is to gather information that could one day lead to trea…

This study is testing whether a new, low-cost type of brain scan can find early signs of Alzheimer's and Parkinson's disease. Researchers will compare brain scans from 120 people, including those at risk for Alzheimer's, those with Parkinson's, and healthy volunteers. The goal is…

This study is testing whether new brain imaging techniques can better diagnose diseases like Parkinson's, multiple system atrophy, and frontotemporal dementia. Researchers will use MRI scans and neurological exams in about 94 adults aged 40-85. The goal is to improve how doctors …

This study tests whether spending less time in bed for four weeks can deepen sleep and boost memory in adults aged 65-85 who have poor sleep and are at risk for Alzheimer's. Researchers will measure brain activity, memory, and blood markers. The goal is to see if a simple behavio…

This study looks at how dementia and mild cognitive impairment (MCI) affect thinking, daily activities, and mood. Researchers will assess 151 adults aged 50-86 with these conditions to better understand their challenges. The goal is to improve care by tailoring treatments to each…

This study collects blood and spinal fluid samples from 100 people with ALS or similar neurodegenerative disorders. The samples are stored for future research to find biomarkers that could help understand or diagnose these diseases. Participants include patients and their spouses…

This study is collecting nerve samples and biofluids from 400 people with ALS or peripheral neuropathies to find biological markers for early diagnosis and disease tracking. By analyzing individual cells, researchers hope to identify molecular changes that happen before symptoms …

This study aims to find new biological markers for neurodegenerative diseases like Alzheimer's, Parkinson's, and ALS. Researchers will analyze genetic, protein, and metabolic data from 1,200 patients to improve diagnosis, predict disease course, and monitor treatment response. Th…

This study looks at how spinocerebellar ataxia (SCA) affects the eyes and vision. Researchers will examine 60 adults with SCA types 1, 2, 3, or 27B, including those with early symptoms and those who are not yet symptomatic. The goal is to measure vision changes and eye damage usi…

This study is looking for 500 people with early dementia or mild cognitive impairment to help develop a way to predict how their disease will progress. Researchers will use blood tests and other models to better understand each person's outlook. The goal is to give patients and d…

This study uses advanced brain scans, including a special PET tracer called AV-1451, to track changes in the brains of 50 people with progressive apraxia of speech (a disorder that affects the ability to coordinate speech movements). Researchers at Mayo Clinic will compare these …

This study uses a special PET scan to measure tau protein buildup in the brains of people with frontotemporal lobar degeneration (FTLD), atypical Alzheimer's disease, and healthy volunteers. Researchers want to see if this scan can help tell these conditions apart. About 72 adult…

This study collects medical information and biological samples (like blood or tissue) from up to 12,000 people with leukodystrophies—rare disorders that damage the brain's white matter. Researchers will use this data to find new genetic causes, develop biomarkers for future trial…

This study collects blood or brain tissue from families with two or more members diagnosed with Alzheimer's or dementia. The goal is to build a large DNA bank that researchers can use to find genes linked to the disease. No individual results are returned, but the data may lead t…

This study is testing whether special eye scans can detect changes linked to memory disorders like Alzheimer's and Parkinson's. Researchers will compare eye images from 450 people with and without memory complaints. The goal is to see if these non-invasive scans can help diagnose…

This study is creating a program called START-VET to help veterans with mental illness or substance use disorders who have recently left prison. Researchers will work with 20 veterans to develop transition materials and tools. The goal is to improve quality of life and reduce cri…

This study collects blood samples from 100 people with rare brain diseases like adrenoleukodystrophy and metachromatic leukodystrophy. Researchers will study immune cells called macrophages to see if they affect how the disease progresses. No treatment is given; the goal is to le…

This pilot study is testing whether a simple saliva test can help doctors prescribe mental health medications more safely and effectively. 200 adults in Manitoba who are starting or changing psychiatric drugs will provide a DNA sample. The results will be shared with their doctor…

This study looks at whether training psychiatric care teams to talk about sexual health with young patients (ages 15 and up) increases those conversations. Researchers will survey 770 teens hospitalized for psychiatric disorders about their sexual health and any side effects from…
