Researchers discover that human brains are growing bigger each generation

The human brain has been growing bigger over the years, according to a new study. Led by the University of California Davis Health, researchers found that babies born in the 1970s had nearly 15 percent more brain surface area and 6.6 percent more brain volume than those born in the 1930s. The study used MRI data from the Framingham Heart Study, which has been ongoing since 1948, and included brain scans from 3,226 subjects.

In addition to an increase in brain volume and surface area, researchers also observed growth in parts of the brain associated with memory and learning. While the implications of these larger brains are still uncertain in terms of intelligence, researchers believe that having a larger brain could be beneficial for brain health. The study suggests that there may be a link between brain size and cognitive decline as people age.

The number of Alzheimer’s disease patients has been increasing with the aging population, but the percentage of newly diagnosed individuals has actually decreased per decade. This information was based on a study published in 2016 in the New England Journal of Medicine, which also analyzed data from the Framingham Heart Study. UC Davis professor of neurology and study first author Charles DeCarli suggested that larger brain structures may reflect improved brain development and health, creating a larger brain reserve that could potentially protect against age-related brain diseases like Alzheimer’s and related dementias. Overall, this research hints at a potential link between brain size and cognitive decline as people age, suggesting that having a bigger brain could be advantageous when it comes to maintaining healthy cognitive function as we age.
