Alzheimer’s Disease and Other Memory Disorders
Featured studies include only those currently recruiting participants. Studies with the most recent start date appear first.
Start Date: July 3, 2019
Location: Bethesda, Maryland
Eligibility: Ages 18 and Older, Accepts Healthy Volunteers
Aging-related progressive neurological disorders include frontotemporal dementia, Lou Gehrig s disease, and Alzheimer s disease. Little is known about what causes these disorders. Brain inflammation may be involved. Researchers want to see if scans using radioactive drugs can show brain inflammation.
To see if the drug [11C]ER176 can show inflammation in the brain in people with certain progressive neurological disorders compared to healthy adults. Also to find genes that might be associated with or cause these disorders.
People ages 18 and older with an aging-related neurological disorder, and healthy adults
Participants will be screened with a medical history, physical exam, neurological exam, psychiatric history, and blood tests.
Participants will have 2-5 visits for the first session. They will have 2 PET scans and 1 MRI scan. They may have 3 more sessions: 6 months to about 18 months later, 1 year after that, and about 30 months to 5 years after the first visit. There may be up to 20 total visits.
For the scans, participants will lie on a bed that slides into the scanners. For the PET scans, a strap will fix their head in place. A radioactive drug will be injected through a catheter. A needle will guide a thin plastic tube into an arm vein. Additional catheters may be put in place to draw blood. Each PET will take 2 hours. The MRI will take 30 60 minutes.
At each session, participants will have a brief interview, medical history, physical exam, blood and urine tests, heart tests, and memory and thinking tests. They may donate blood for DNA tests.
