Study finds mental exercises can reverse brain aging: Here are 5 exercises for better cognitive health

Aging affects everyone, and one of its biggest impacts is on the brain. As we grow older, our memory, focus, and attention naturally begin to decline. But new research suggests that while we can’t stop aging, we may be able to slow, or even slightly reverse, some of its effects on the brain.

Scientists have found the first compelling evidence that mental exercises can actually increase levels of a brain chemical that typically declines with age.

In a 10-week study conducted by researchers at McGill University in Montreal, adults aged 65 and older performed mental exercises for 30 minutes daily. The result: their levels of acetylcholine, a chemical messenger linked to attention and memory, rose by 2.3% in a key brain area.

“The increase is not huge,” said Étienne de Villers-Sidani, the study’s lead neurologist. “But it’s significant, considering that you get a 2.5% decrease per decade normally just with aging.”

In other words, this boost is roughly equivalent to turning back the brain’s clock by about 10 years.

Researchers studied 92 healthy adults aged 65 and above. Half of them played casual computer games like solitaire or Candy Crush, while the other half used BrainHQ, a scientifically tested program designed to challenge memory, speed, and attention.

Those who engaged in structured cognitive training saw notable increases in acetylcholine, not just in attention-related areas but also in the hippocampus, a region crucial for memory formation. In contrast, participants who played casual games showed no improvement.

Just like physical workouts strengthen your body, mental exercises keep your brain active and alert. These activities challenge your memory, attention, and problem-solving skills, helping slow down cognitive decline

Whether you’re assembling a 1,000-piece Eiffel Tower or a simple 100-piece cartoon, puzzles engage multiple parts of your brain. Research shows they help preserve visuospatial reasoning and delay cognitive decline. Plus, they’re relaxing and rewarding once you see the full picture come together.

Card games like bridge, poker, or even UNO aren’t just fun, they can sharpen thinking skills. Studies show that such games improve self-control, attention, and task-switching abilities in both children and older adults. Regular play can boost verbal fluency and memory too. You can always try solitaire, bridge, gin rummy, poker, hearts or even crazy eights.

Learning new words stimulates brain areas related to visual and auditory processing. Keep a small notebook, jot down one new word while reading, look up its meaning, and try using it five times the next day. You’ll sound smarter, and your brain will get a workout.

Learning new dance moves enhances coordination and memory. According to the Centers for Disease Control and Prevention (CDC), dancing increases processing speed and mental flexibility. So the next time you hit the dance floor, remember, it’s great cardio for your brain too.

One way to keep your brain thriving is to learn a new skill. Taking up a new hobby like painting, playing an instrument, or learning a language can build stronger neural connections. A 2023 study found that older adults who learned multiple skills at once improved memory and thinking to levels similar to those of middle-aged adults. It’s never too late to learn, or to grow your brain.
