A new McGill-led study reveals that digital brain exercises can rejuvenate aging brain systems responsible for learning and memory. Older adults using BrainHQ for 10 weeks showed restored cholinergic function — effectively turning back the brain’s clock by a decade. Scans confirmed measurable biochemical changes, offering a hopeful new approach for dementia prevention.
After 10 weeks of using the game-like app BrainHQ, older adults showed significant improvements in cholinergic function, a key brain chemical system that tends to decline with age and affects attention, memory, and decision-making.
