A landmark 20-year NIH-funded clinical trial has revealed that fewer than 24 hours of cognitive speed training—a specific type of brain exercise that challenges participants to rapidly identify visual targets under time pressure—reduced dementia diagnoses by 25% over two decades. The finding, published in February 2026 from the ACTIVE study, is the first randomized trial evidence that a brief, non-pharmacological intervention can deliver lasting protection against Alzheimer's disease and other dementias, though experts caution that not all brain training is created equal.
