Experts say playing trivia games can provide a dopamine rush much like gambling, without the negative effects

I bet your doctor and stroke hospital  will never provide this basically free intervention.  When I wasn't traveling for work I would play Team Trivia twice a week at bars. Great for your social connections and with drinking some alcohol great for your balance training. Triple your stroke rehab at one time/place. I bet your doctor never thinks of this.

It can be quite satisfying and doesn’t have many downsides.
That’s how psychologists describe the mental health benefits of trivia.
The way people play trivia games continues to evolve whether it’s folks enjoying Trivial Pursuit at home or attending a pub trivia night.
But the basic premise remains the same: People enjoy the thrill of providing correct answers to questions about lesser-known facts.

Trivia Question #1

Who was the first U.S. president born in a hospital?

“You get a rush or a neuroreward signal or a dopamine burst from winning,” John Kounios, Ph.D., professor of psychology and director of the doctoral program in applied cognitive and brain sciences at Drexel University in Pennsylvania, told Healthline. “I think whenever you’re challenged with a trivia question and you happen to know it, you get a rush. It’s sort of like gambling.”
He said the benefits can also be similar to those of playing a video game.
However, unlike gambling and even video games, Kounios says trivia is generally not a habit that’s a problem.
“I don’t think there are any pitfalls,” he said. “Like anything else that’s fun, it takes up time.”
