Gandy’s work prompted further investigation into how genetic and environmental factors interact to cause Alzheimer’s.

Caleb Finch, Ph.D., at the University of Southern California also determined in his study that air pollution might have a role in elevating the risk for Alzheimer’s disease. Finch’s study cited nanoparticles emitted from vehicle exhaust as potential threats. He estimates that pollution from such particles contributes to at least 5% of all Alzheimer’s cases. Finch was awarded a multi-year grant from the National Institutes of Health to continue investigating this subject.
