Higher common genetic risk for major depression links to slightly smaller brains and reduced cortical surface area, including subtle reductions in emotional and memory regions.
Experts are finding that the best way to understand how the brain ages is not by examining individual parts, but by studying its overall structure and how its different regions interact with one another. In a large study, researchers from Irvine, California and Tenerife, Spain, used brain scans to measure these shape changes. They discovered that as people age, the brain does not shrink evenly. Instead, it changes shape in specific ways.
