In brief

• A 2025 Nature Communications study found that people engaged in demanding creative activities—especially complex video games—had brains that appeared 4–7 years younger.
• In controlled tests, non-gamers who trained on StarCraft II showed measurable improvements in brain efficiency; slower, turn-based games did not.
• The benefits seem tied to real-time complexity and cognitive load, not gaming per se, and don’t replace mental-health gains from exercise.

The relentless march of time takes an inevitable toll on cognitive function. Yet, emerging research suggests a surprising countermeasure against neural decline may lie not in a pharmaceutical solution, but in complex, demanding recreational activities—including sophisticated video games.

According to a 2025 study published in the peer-reviewed scientific journal Nature Communications, individuals deeply engaged in specific "creative" tasks—defined in the study as video games, music, dance, and visual arts—possess brains that appear significantly younger than their actual chronological age. The findings offer compelling evidence that certain cognitively demanding hobbies can boost neural plasticity, potentially buffering against age-related decline.

The study, led by researchers Carlos Coronel and Agustin Ibanez, utilized machine learning to analyze brain scans taken via EEG and MEG. By mapping neural activity patterns, the researchers estimated a biological "brain age" for each participant. The results showed that, on average, the brains of experienced gamers and artists appeared 4 to 7 years younger than those of non-experts.

To determine if these activities actually caused the anti-aging effect, rather than simply attracting people with healthier brains, the researchers conducted a controlled experiment. They tasked non-gamers with playing StarCraft II, a complex real-time strategy game that requires intense multitasking, planning, and rapid attention shifts, for roughly 30 hours over several weeks.

Following the training period, these new players showed a measurable slowing of brain aging and increased brain efficiency.

Crucially, the study found that not all games yield the same results. A separate control group played , a slower-paced, turn-based card game, and did not show significant cognitive benefits. This discrepancy suggests that the complexity and real-time demands of the activity are what drive the anti-aging benefit. The researchers compare the cognitive load of these complex games to the neural demands of learning a new language or musical instrument.
