- A cognitive speed training game reduced dementia risk by 25% in a prior study, with new research showing it alters beta-amyloid levels in men but not women.
- The training involves recalling object locations and increases the ratio of beta-amyloid forms in men's blood, suggesting enhanced brain clearance of amyloid plaques linked to Alzheimer's.
- While Alzheimer's drugs like lecanemab have limited effects late in the disease, cognitive training may offer greater benefits by reducing amyloid buildup before significant brain damage occurs.
- The study included 53 older adults; only speed training affected amyloid in men, with no effect from other brain games or training types.
- Researchers aim to verify findings in diverse groups and explore how speed training benefits women differently, as it may reduce dementia risk through distinct mechanisms.
