A groundbreaking study from Trinity College Dublin highlights how adverse social experiences such as limited education, food insecurity, financial stress, limited access to healthcare, and traumatic events across life can have lasting effects on mental and cognitive health. Researchers found that experiencing more adverse events over a lifetime is linked to poorer cognition, mental health, and changes in brain structure, especially in people living with dementia. Importantly, the study emphasizes that dementia prevention should begin early, suggesting that improving social conditions and social support from childhood onward can build brain health that lasts a lifetime.
