About this episode

This episode explores a study on computerized cognitive training and its impact on brain chemistry in older adults.

In this episode, we dig into a recent McGill University study on computerized cognitive training and its effects on brain chemistry in older adults. What you'll learn: Why certain brain training games reversed a decade of age-related cognitive decline in just 10 weeks—and how researchers finally measured actual biological changes in the brain The critical difference between activities that genuinely enhance your brain versus mental junk food like Candy Crush or Solitaire The single organizing principle you can use to evaluate whether any cognitive activity is actually helping your brain or wasting your time To submit a question for us to answer on the podcast, go to brainjo.academy/question .
