Mythbusters 2: Fact vs. Fiction

See our earlier article for more busted myths.

Myth: I don't need to train my brain, it works fine as-is.
Reality: Would that this were indeed the case. The fact is, research demonstrates that brain training is indeed effective in reducing brain age -- so long as it's the right type of brain training. The key is increased blood flow in the prefrontal cortex, the so-called "control tower" of the brain, indicating that the brain is being adequately challenged and stimulated. This neural activation signifies that the game or activity is sufficiently challenging to push the brain to adapt and strengthen.

Myth: Brain training games are just digital snake oil and don’t really help improve cognitive functions.
Reality: Despite skepticism, research by Dr. Ryuta Kawashima at Tohoku University shows that meaningful brain training can engage the dorsolateral prefrontal cortex, which is crucial for executive functions like problem-solving and planning.

Myth: Brain training won't actually alter my brain in any fashion, so why bother?Reality: Think of the brain as a garden and brain training being analogous to caring for a plant. According to research done at Kawashima Laboratory at the Institute of Development, Aging and Cancer (IDAC), Tohoku University, the volume of the cerebral cortex is actually increased by brain training (specifically, by training working memory). Moreover, memory and learning abilities are improved, together with a boost in concentration and creative ability.

‍Myth: Brain training is only wishful thinking and the games don’t have any real benefits.
Reality: Research has shown that targeted exercises can improve brain age and promote neuroplasticity. Accordingly, the market for these apps is growing, especially among a populace eager to keep its minds sharp well into old age.

Myth: All brain training games are equally effective.
Reality: Not all brain training games are created equal. Dr. Kawashima’s research highlights that meaningful brain training involves challenging tasks that increase blood flow in the prefrontal cortex, indicating adequate brain stimulation.

Myth: Brain training games should be immediately gratifying and easy to play.
Reality: Meaningful brain training games require effort and concentration, but they can still be entertaining. In fact, research shows that the best brain training regimen consists of basic tasks like reading aloud, or basic arithmetic done at a rapid pace.

Myth: Brain training works the same for everyone.
Reality: The effectiveness of brain training can vary from person to person. What works for one individual might not work for another, highlighting the personalized nature of meaningful brain training. The most important thing to keep in mind is that you can train your brain at any age.

Myth: Brain training games must be difficult because only harder exercises will sufficiently challenge the brain.
Reality: Games that challenge higher brain functions, such as executive function, working memory, and problem-solving, offer the most potential for genuine cognitive improvement. Bear in mind that receiving real-time feedback during training is equally important so that you know which exercises work best for you.
