The Secrets to Keeping Your Brain Sharp in Old Age

A New Scientist feature surveying the rapidly converging science on cognitive resilience in older age — including the Northwestern SuperAging Program (people over 80 with memory like 50-year-olds), Harvard's super-ager work, U.S. POINTER trial results on lifestyle interventions, BrainHQ-style speed-of-processing training, and the consistent finding that social engagement halves dementia risk. The piece's thesis: cognitive decline is not inevitable, and the levers (sleep, exercise, social connection, deliberate cognitive challenge, hearing-loss management) are well-evidenced and largely within personal control.
