Video Games That Boost Brain Function

Video Games That Boost Brain Function

Author: Josh Turknett, MD February 10, 2026 Duration: 0:00

In this episode, we explore a rigorous meta-analysis examining how action video games, particularly first and third-person shooters, affect cognitive function in young adults. The research reveals promising evidence that these games can enhance processing speed and selective attention, with the strongest benefits coming from games requiring rapid environmental responses and decision-making under time pressure.

What we discussed:

  • How action video games like Halo and Call of Duty improve processing speed and selective attention more than traditional brain training apps

  • Why games requiring rapid responses to the environment create cognitive benefits that are hard to replicate in daily life

  • The specific game features that matter most: unpredictable environments, time pressure, and rapid response demands

  • Practical game recommendations for adults new to gaming, including accessible options on Nintendo Switch and modern smart TVs

  • How to balance gaming benefits with potential downsides like sleep disruption and social isolation

What does it really mean to have a fit brain, and how do we actually achieve it? That’s the central question explored in Better Brain Fitness (a Brainjo Production), a conversation guided by neurologist Dr. Josh Turknett and neuroscientist Dr. Tommy Wood. Moving beyond generic advice, each episode digs into the practical, often surprising science of cognitive longevity. You’ll hear discussions that translate complex research into actionable strategies, covering everything from nutrition and sleep to movement and mental challenge. The aim isn’t just about preventing decline, but actively building a resilient, high-performing mind that supports your passions and daily life. This podcast operates on the principle that our brain’s health is malleable at any age, and that understanding the underlying mechanisms empowers us to make better choices. Tune in for a nuanced look at how lifestyle intersects with neurology, stripping away the hype to focus on what evidence suggests truly works. It’s a resource for anyone curious about taking a proactive, informed role in their own cognitive well-being, ensuring the brain remains a robust partner for all the years ahead.
