Brain-boosting games like Mahjong may help fight dementia, Tulsa doctor says

While dementia can’t always be prevented due to genetic and age-related factors, there are ways to support brain health through intentional activities, according to Dr. Stacy Chronister, an internal medicine specialist with OSU Medicine. Chronister said the goal isn’t to regenerate nerves, but to create new connections in the brain.

“When you learn a new language or practice memory skills, you’re actually forming new neural pathways,” Chronister said. “That’s why people can sometimes recover lost function after a stroke—it’s the brain finding new ways to connect.”

Games That Improve Cognitive Function

Chronister said engaging in mentally challenging and socially interactive games can help strengthen those neural connections. One of her favorites is mahjong, a game she plays weekly.

“It increases your social interactions and includes critical thinking and problem-solving,” she said. “They’ve even shown that just 12 weeks of playing mahjong can improve memory, attention and everyday tasks like grocery shopping and driving.”

Other games with research-backed benefits include:

1. Tetris, which has been used as an adjunct therapy for PTSD and helps with visual-spatial processing.
2. Mario Brothers, which boosts coordination and attention span.
3. Animal Crossing, which supports social interaction and reduces anxiety and depression.
4. Dungeons and Dragons, shown to help with social engagement in individuals on the autism spectrum.

Finding Ways To Get Involved

For those who are isolated or unsure where to start, Chronister recommends looking up local community groups, especially on Facebook or other neighborhood pages.

“There are a lot of open play opportunities in the Tulsa area,” she said. “I started by taking a day off and going to a mahjong camp. It was so much fun—I’ve played every week since.”

Even solo games like Wordle, Sudoku, and crosswords can benefit the brain by encouraging problem-solving and language skills, Chronister added.
