DOI: 10.1038/s41591-024-03209-x The pace at which the brain ages can vary significantly among individuals, leading to a gap between the estimated biological age of the brain and the chronological age (the actual number of years a person has lived). This gap may be influenced by various factors, including physical (e.g. pollution) and social (e.g. socioeconomic or health inequalities) exposomes, especially in aging and dementia. Until now, it was unclear how these combined factors could either accelerate or delay brain aging across diverse geographical populations. Now, in a trailblazing study published in Read More
