The Alzheimer's Disease and Memory Disorders Center has established an ongoing collection of serum from patients with Alzheimer's disease (AD) and other conditions as well as those with normal cognitive functioning. The project involves the voluntary collection of blood samples from cognitively healthy volunteers and patients enrolled in the ADMDC, and has been approved by the Institutional Review Board for Baylor College of Medicine. The purpose of this project is to help researchers identify a biochemical marker in blood that could be used to diagnose AD or to identify different subtypes of AD.
The project has been ongoing since 1988 and involves only those persons who wish to participate and sign an informed consent to do so. Approximately five teaspoons of blood are collected from each participant each time consent is granted. The sample is then frozen and banked for future use by researchers who are investigating normal aging and neurological diseases affecting older adults.
