How the Aging Brain Affects Thinking - National Institute on Aging
How the brain changes as people age. As a person gets older, changes occur in all parts of the body, including the brain. Certain parts of the brain shrink, including those important to learning and other complex mental activities. In certain brain regions, communication between neurons may be less effective.

Changes That Occur to the Aging Brain | Columbia Mailman
Jun 10, 2021 · What Changes Occur When the Brain Ages? In the early years of life, the brain forms more than a million new neural connections every second. By the age of 6, the size of the brain increases to about 90% of its volume in adulthood. Then, in our 30s and 40s, the brain starts to shrink, with the shrinkage rate increasing even more by age 60.
