Researchers from Trinity College Dublin, along with international partners, conducted a study published in Nature Aging that explores the impact of societal inequality on the brain. The research revealed a direct link between structural inequality measured by a country-level index (GINI) and changes in brain structure and connectivity associated with aging and dementia. Higher inequality levels were found to be linked to reduced brain volume and disrupted connectivity, particularly in vulnerable Latin American populations. The study emphasizes the need to address root causes of brain health disparities specific to each region through targeted interventions. The research calls for a multi-level approach to brain health equity, considering various macro-level factors beyond socioeconomic inequality.
