Just 5 weeks of brain training may protect against dementia for 20 years
Summary
A 20-year randomized study finds that a 5- to 6-week adaptive speed-of-processing training in adults 65+ reduces dementia incidence by about 25% two decades later, especially when boosters are included. The findings, published in Alzheimer’s & Dementia: Translational Research and Clinical Interventions, suggest nonpharmacological cognitive training can have lasting brain-health benefits, though mechanisms remain unclear and effects were not seen with memory or reasoning training.
