"The way your brain ages, it's not just about years. It's about where you live, what you do, your socio-economic level, the level of pollution you have in your environment," says Agustín Ibáñez, the study's lead author. He emphasizes that addressing structural inequalities is crucial for improving brain health. This highlights how social determinants significantly impact cognitive aging, urging countries to invest in policies that consider these factors for better overall brain health outcomes.
The research noted that brains age faster in women and in countries with greater inequality, particularly in Latin America. It illustrates how functional connectivity, which shows how regions of the brain interact, declines with age, impacting cognitive health. The study's findings suggest that socio-economic factors and environmental conditions play a critical role in brain aging, reinforcing the need for comprehensive approaches to health that consider not just biological but also social elements.
