Official title
11C-Acetate Position Emission Tomography/Computerized Tomography (PET/CT) Imaging As a Biomarker of Amyloid-Induced Neuroinflammation
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The proposed study aims to use 11C-acetate position emission tomography/computed tomography (PET/CT) to preliminarily test and validate methods for imaging astrocyte activation as an early indicator of neuroinflammation in Alzheimer's disease (AD). 11C-Acetate PET/CT has been shown to quantify astrocyte activation in vivo, but no reports have evaluated its potential in AD. The investigators propose to test 11C-Acetate PET/CT as a marker for astrocyte activation associated with pathologic amyloid deposition in AD. The investigators will compare binding between subjects with early stage AD and healthy controls. Further, the investigators will investigate the correlation between amyloid and acetate binding. If the investigators find increased astrocyte activation in response to cerebral amyloid by showing a group difference in brain acetate uptake between disease and controls or a strong correlation between acetate and amyloid PET/CT binding. Validating neuroinflammation markers in AD ultimately may guide therapeutic modulation of beneficial and damaging neuroinflammation to slow disease progression, as well as providing new insights into AD pathophysiology.
