Growing Brains, Healthy Minds: Study Suggests Larger Brain Volume May Offer Protection Against Age-Related Dementia

Researchers Discover Human Brains Are Increasing in Size

A study led by the University of California Davis Health has revealed that human brains have been getting bigger over the years, potentially offering benefits for brain health as people age. Researchers analyzed MRI data of individuals born between the 1930s and 1970s and found that babies born in the 1970s had larger brain surface area and volume compared to those born in the 1930s.

The study, published in JAMA Neurology, also showed that areas of the brain related to memory and learning had grown in size. While larger brains may not necessarily equate to increased intelligence, researchers believe that having a bigger brain could be beneficial for brain health.

Further research is needed to fully understand the implications of larger brains on brain health and cognitive function. However, a study published in 2016 in The New England Journal of Medicine suggests that larger brain structures observed in the recent study could indicate improved brain development and health, potentially providing a buffer against age-related brain diseases like Alzheimer’s and dementia.

The findings suggest that having a bigger brain may offer protection against age-related brain diseases. This could be due to larger brain reserve and improved brain health, allowing for better brain function as individuals grow older.
