Unraveling the Mysteries of Brain Aging: Genetics, Predictions, and Lifelong Performance
The Lothian Birth Cohorts study, conducted by the University of Edinburgh, has tracked the cognitive abilities of individuals from age 11 into their 70s, 80s, and 90s, revealing that about half of our intelligence in old age is determined by childhood cognitive abilities. The study highlights the significant variation in brain aging among individuals and suggests that while genetic factors and childhood intelligence play roles, lifestyle choices like physical activity and education also influence cognitive aging. The research underscores the importance of multiple small lifestyle changes to promote healthier brain aging.
