Evaluation of a Handheld Event Related Potential (ERP)/Quantitative Electroencephalography (qEEG) System (COGNISION™) as a Useful Cognitive Biomarker for Alzheimer's Disease.

The proposed study is designed to evaluate the performance of the COGNISION™ System as a tool to assist physicians in diagnosing Alzheimer's Disease (AD) in real-world clinical settings. The design of this study is guided by two overriding factors: 1) to optimize the performance of the event related potentials (ERP) classifiers, the subjects making up the training sets must be well characterized as to their clinical diagnosis, and 2) all ERP tests must be performed and reproduced in real-world clinical settings.
