A groundbreaking study from McGill University has revealed that digital brain training can rejuvenate aging brain systems responsible for learning and memory. After using the game-like app BrainHQ for 10 weeks, older adults showed restored cholinergic function – effectively turning back their brains’ clock by a decade. This discovery offers a hopeful new approach to preventing dementia.
A clinical trial led by McGill University has shown that online brain training can strengthen the brain networks responsible for learning and memory in older adults. The study found that after 10 weeks of using BrainHQ, participants showed significant improvements in cholinergic function, which affects attention, memory, and decision-making.
The researchers used a specialized PET scan to observe changes in brain activity before and after the training period. They discovered measurable biochemical changes that confirmed the effectiveness of BrainHQ. The study’s findings suggest that this type of brain training could serve as a safer alternative to medication or work effectively alongside it.
This research has significant implications for dementia prevention, as Alzheimer’s disease is linked to sharp declines in cholinergic health. The study’s results provide evidence-based support for the use of brain games like BrainHQ as a tool for maintaining or improving brain health.
