The research tracked participants from childhood through their eighties, linking higher childhood intelligence to improved longevity. This study also revealed significant differences in brain aging, suggesting that genetics and early-life factors profoundly shape cognitive health.Read More

Analyzing data from a unique natural experiment involving nearly 30,000 individuals, researchers found no detectable impact on brain structure from an additional year of education. Although education is linked to better cognitive skills and health, it does not appear to alter the brain’s physical structure in the long run.Read More

The study found that lower blood sugar levels were linked to a younger brain age, particularly in regions critical for memory and sensory processing. Using advanced MRI scans, researchers observed that participants on the Green-Med diet exhibited a slower rate of brain atrophy over 18 months.Read More
