For the first time, scientists have mapped the genetics of how the brain ages, region by region

A landmark research paper for the first time maps the genetics of how individual regions of the brain age—and why some of those regions are the very ones most ravaged by Alzheimer's and dementia. Published in the journal GeroScience, the paper is titled "Deep Neural Networks and Genome-Wide Associations Reveal the Polygenic Architecture of Local Brain Aging."
