Manual Driving Tied to Better Brain Health, Study Finds 2026

Driving a manual transmission car may do more than just provide a more engaging experience behind the wheel—it could also have a significant effect on maintaining mental health and cognitive function, according to a new study from Tohoku University in Japan. The research, led by neuroscientist Ryuta Kawashima, suggests that the extra mental workload of shifting gears might give manual drivers an unexpected brain boost.

Who Is Ryuta Kawashima?

If the name sounds familiar, you might recognize him as the scientific mind behind Nintendo's popular Brain Age and Dr. Kawashima's Brain Training series. Those games, released between 2003 and 2020, were designed to give players a daily dose of mental gymnastics. Now, Kawashima is turning his attention from virtual brain training to real-world driving.

Kawashima is a professor at the Institute of Development, Aging and Cancer at Tohoku University. His latest work examines how the act of driving different types of vehicles impacts brain activity, particularly in the prefrontal cortex—the area responsible for memory, decision-making, and attention.

What the Study Found

The research compared the brain activity of drivers operating manual and automatic cars. According to Japanese outlet Best Car Web, Kawashima's team observed clear differences in prefrontal cortex activity between the two groups. Manual drivers showed increased engagement in this critical brain region.

Kawashima explains that driving a manual requires the driver to constantly judge speed, engine sound, and road conditions to execute smooth gear changes. This continuous multitasking may stimulate the brain more than the relatively passive act of driving an automatic.

Why It Matters for Mental Health

The prefrontal cortex plays a key role in higher-level cognitive functions. If manual driving indeed exercises this area, it could help keep the brain sharp as we age. Kawashima's previous work with Brain Age was built on the idea that mental stimulation can slow cognitive decline. Now, it seems that everyday activities like driving a stick shift might offer similar benefits.

For car enthusiasts who have long argued that manual cars are more fun, this study provides scientific backing for their preference. Beyond enjoyment, it suggests that the extra effort required to drive a manual could contribute to long-term brain health.

Key Takeaways from the Research

• Manual driving engages the prefrontal cortex more than automatic driving, potentially improving cognitive function.
• The study was led by Ryuta Kawashima, the neuroscientist behind Nintendo's Brain Age series.
• Mental multitasking—judging speed, sound, and road conditions—may be the key to the brain boost.
• The findings add scientific weight to the argument that manual cars are more engaging to drive.
• While the research is promising, it's not yet clear how long-lasting these effects are.

How Manual and Automatic Driving Compare

To understand the difference, it helps to look at what each type of driving demands from the brain.

What to Watch Next

While the study provides intriguing evidence, it's important to note that the research is still in its early stages. Kawashima's team has not yet published the full details, and more research is needed to confirm the long-term effects. Future studies could explore whether manual driving offers lasting cognitive benefits or if the effect diminishes over time. Earlier coverage in Learning Languages Boosts Brain Health and Confidence shows how the argument developed. A closer look at the same subject appears in Learning Languages Boosts Brain Health and Career Success.

For now, manual car fans have another reason to celebrate their choice. Not only does a stick shift offer a more connected driving experience, but it might also be a simple way to keep your brain active behind the wheel.
