Our biological age, modulated by living habits, influences brain ageing beyond our chronological age

20/01/2023

A person's biological age, in other words, the real age of their body, which is independent of chronological age and which can be measured in specific blood tests, is conditioned by their lifestyle habits. A study by the Neurovascular Research Group at the Hospital del Mar Medical Research Institute, published in the journal Biology, has for the first time associated a higher biological age with the presence of an indicator of brain ageing, white matter hyperintensities, areas of the brain that blood has a harder time reaching. Lifestyle habits influence the DNA configuration and determine biological age. If these habits are modified, DNA ageing and, therefore, biological ageing can be slowed down, thereby decelerating the increase in white matter hyperintensities in brain tissue.
