A quick online search on ways to keep your brain sharp reveals a host of apps that claim to help prevent cognitive decline. But is there any proof that these tools actually help boost your brain health?
“While popular brain training apps claim to keep your mind sharp and improve your memory with research-backed cognitive training tasks and training programs, many of which can be personalized, we can't say for sure whether that translates to long-term brain benefits,” says Marc L. Gordon, MD, chief of neurology at Zucker Hillside Hospital and professor of neurology and psychiatry at the Donald and Barbara Zucker School of Medicine at Hofstra/Northwell.
The breakdown on brain apps
Some studies show that playing digital games and apps can yield improvements in working memory and thinking speed, for instance. But the positive effects only seem to stick around if you play regularly and for long stretches (think 30 minutes or longer). In addition, there’s no proof that these apps can actually prevent or slow down cognitive decline.
That led the National Institute on Aging to declare, for now, that there's not enough evidence to say whether computer games and apps are truly beneficial for your brain. And certain apps have come under fire by the Federal Trade Commission for not living up to their claims.
Despite the mixed findings, Gordon isn’t anti-brain game. “But I do think it's important for users to have realistic expectations about what the games can do for you,” he adds.
Brain-training apps tend to have users perform specific cognitive tasks, like memorizing letter sequences or quickly solving math problems. Do the tasks over and over, and you'll certainly get better at them. However, it's unclear whether advancement in those tasks yields improvement in wider areas of cognition, or if those achievements translate to everyday activities.
“It's sort of like learning to cook by making the same recipe over and over,” explains Gordon. “You'll get great at making that dish and eventually you could probably do it with your eyes closed. But being a pro at pasta primavera or lentil soup isn't the same as being able to whip up a tasty meal with whatever's in the fridge.”
As Gordon points out, though, if you enjoy playing a game or using an app, you should go for it. Just keep your usage short so it’s not taking time away from meaningful real-world activities. And make sure that you’re also doing a variety of other things throughout your day to protect your cognitive health.
Brain-boosting habits
Gordon tells his patients that brain health is the culmination of healthy habits, including:
Regular exercise: Find ways to be active every day, like taking a brisk walk, swimming, or lifting weights.
Mental engagement: Do things that challenge you. Learn a new skill, take up a hobby that requires some concentration, and spend more time reading.
Social interaction: Interacting with others is a form of mental engagement that can also boost your mood. Try doing a stimulating activity with family members or friends, like taking a hike or playing a board game.
