1970s-born humans have larger brain volumes and surfaces, potentially reducing dementia risks.
Researchers at UC Davis Health discovered that human brains are growing larger, with 1970s-born participants having 6.6% larger brain volumes and 15% larger brain surface areas than those born in the 1930s. This increase may lead to a larger brain reserve, potentially reducing age-related dementia risks. The study used MRIs from the Framingham Heart Study, comparing white matter, gray matter, and hippocampus growth among generations.
