How Inequality Speeds Up Brain Ageing | Groundbreaking Study Reveals Surprising Findings

🌍 **How Inequality Speeds Up Brain Ageing | Groundbreaking Study Reveals Surprising Findings** 🧠

Our brains don't all age the same way—some age faster due to factors beyond our control. A recent study, published in *Nature Medicine*, dives deep into how social and physical environments, especially inequalities like economic status, pollution, and disease, can accelerate brain ageing. 🌱

International researchers, including a team from the University of Surrey, used advanced brain clocks and analyzed over 5,300 participants across 15 countries to uncover that greater inequality leads to older brain ages. This is especially true in countries with significant disparities, where people’s brains tend to age faster in regions most affected by ageing.

Key findings include:
- Countries with higher inequality show faster brain ageing.
- Social and environmental factors, like air pollution and disease, significantly impact brain health.
- Women, particularly in Latin American and Caribbean regions, show greater brain age gaps, linked to both biological and gender disparities.
- The study’s insights could revolutionize personalized medicine by identifying those at risk for neurodegenerative diseases like Alzheimer's.

This research emphasizes the urgent need for public health policies that address socioeconomic inequalities and environmental pollution to reduce brain age gaps and promote healthier ageing worldwide. 🌍
