While conventional MRI techniques take a qualitative image, our advanced MRI technique programs the scanner to function more like a quantitative measuring instrument to measure myelin - the insulating layer around the “wires” in the brain.
The purpose of this study is to determine the relationships among the clinical, cognitive, imaging, genetic and biochemical biomarker characteristics of the entire spectrum of Alzheimer's disease (AD), as the pathology evolves from normal aging through very mild symptoms, to mild cognitive impair
