This topic matters to anyone thinking about how societies support human potential. If environmental and social conditions are eroding cognitive resilience, interventions could restore functioning and widen access to healthy, productive lives. Follow the full story to see what evidence researchers are uncovering and how their findings might guide policies that protect thinking and learning for all.
