Decoding Brain Aging: Insights from a 25-Year Study
Originally Published 1 year ago — by SciTechDaily
A 25-year study by the University of Edinburgh, published in Genomic Psychiatry, reveals that nearly half of the variance in cognitive ability in older age can be traced back to childhood. The research, based on the Lothian Birth Cohorts, highlights significant individual differences in brain aging and suggests that early-life cognitive ability influences later brain health. The study challenges conventional views on cognitive decline, emphasizing the role of genetics and early cognitive differences, and suggests potential areas for future research on lifestyle and environmental factors affecting brain health.
