Overview
Brief Summary
The purpose of this research is to better understand how dementia affects activity in different parts of the brain.
Detailed Description
This study is being done to examine the usefulness of Positron Emission Tomography (PET) imaging with florbetapir F 18 as a biomarker in the identification of amyloid-ß peptide (Aß) in the brain. Amyloid-ß peptide (Aß) accumulates in the brains of patients with Alzheimer's disease. Florbetapir F 18 sticks to the amyloid plaques in the brain and emits a low level of gamma rays which can be detected by a PET camera. The development of biomarker and imaging studies that track the development of PPA and reflect the change in people's bodies may help other people who have a similar medical problem in the future.

Arms & Interventions
Florbetapir F 18 Recipients
Participants in this arm of the study will receive a 10 mCi (370 MBq) bolus injection of florbetapir F 18 and then be scanned in a PET scanner for brain imaging.

Outcomes
Primary Outcomes
Detecting amyloid burden in subjects with neurodegenerative diseases
Time Frame: 4 years
The study will provide standardized conditions for florbetapir F 18 use, amyloid binding as measured by PET imaging, and long-term outcome in cognitively normal volunteers, patients with Alzheimer's Disease, patients with Mild Cognitive Impairment, and patients with other neurodegenerative diseases. It will also facilitate evaluation of subject's amyloid burden in companion studies such as longitudinal studies of aging, studies of progressive cognitive impairment, and studies of imaging and blood/cerebrospinal fluid biomarkers of neurodegenerative disease.
