Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Alzheimer's disease (AD) is characterized by neuritic plaques, neurofibrillary tangles, and neuronal cell loss. Amyloid plaques are believed to play an integral role in AD. Elevated levels of Aβ in the brain are correlated with cognitive decline. There are no approved ways to measure amyloid load in humans. Several compounds are under investigation. All of these compounds use radioactive chemical tags for positron emission tomography (PET) imaging. The most promising compound is 11C-PIB, or Pittsburgh Compound-B. This compound can be injected and a PET scan performed. This allows doctors to see the amyloid plaques in the brain, and to use this information to look at other types of dementia to see if there are differences and/or similarities in the plaques. We will recruit a total of 30 subjects, 10 from each of the following three diagnostic categories: frontotemporal dementia (FTD), Alzheimer's disease, and normal volunteers. All subjects will be given an \[18F\]fluorodeoxyglucose or FDG-PET scan (if they haven't had one in the past) and a PIB-PET scan. The overall objective of this project is to study the biodistribution of 11C-PIB using PET imaging in normal elderly volunteers and relevant patient groups.
