Measuring brain amyloid levels in Alzheimer's patients

UAB Alzheimer's Disease Center Core Cohort - Imaging Substudy

PHASE2 · University of Alabama at Birmingham · NCT03503331

This study is testing how amyloid levels in the brains of people with Alzheimer's relate to their health and background to see if early brain scans can help predict memory problems.

What this trial studies

This study aims to assess the concentration and distribution of amyloid deposits in the brain using the PET tracer [C-11]PiB among participants in the UAB Alzheimer's Disease Center cohort. It will correlate amyloid levels with demographic, clinical, genetic, and biospecimen data from an ongoing study. Additionally, the study will evaluate how race and vascular risk factors interact with brain amyloid levels and cognitive status. A secondary goal is to determine if early imaging results can predict cognitive decline.

Who should consider this trial

Good fit: Ideal candidates are individuals enrolled in the UAB-ADC study who are undergoing assessment for Alzheimer's disease.

Not a fit: Patients with severe dementia or those unable to undergo MRI or PET imaging may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance understanding of Alzheimer's disease progression and improve diagnostic methods.

How similar studies have performed: Other studies using PET imaging to assess amyloid deposition have shown promising results, indicating this approach is supported by prior research.
