Let me tell you about something that genuinely excited me when I came across it this week. Scientists have found evidence that picking up a guitar, keyboard, or basically any musical instrument in your 70s might help protect your memory. Not "might help a little bit" — I'm talking about measurable differences in brain structure and cognitive function.
Wait, Your Brain Can Still Change in Your 70s?
Here's what blows my mind about this research: we used to think our brains were pretty much fixed once we hit a certain age. Like, the thinking was that neuroplasticity — your brain's ability to rewire itself — was mostly a young person's game.
But this study from Kyoto University suggests that's simply not true.
Researchers followed a group of adults who started learning musical instruments for the first time around age 73. After an initial four-month training period, about half the participants kept practicing while the others moved on to different hobbies. Four years later, the differences were remarkable.
What Exactly Did They Find?
The scientists focused on two brain regions that tend to shrink as we age: the putamen and the cerebellum. Think of the putamen as your brain's rhythm coordinator and the cerebellum as helping with timing and motor control. Both are heavily involved when you play music.
Here's what happened:
People who stopped playing showed declining verbal working memory (that's your ability to hold and manipulate information in your mind — like remembering a phone number while you look for a pen) and their right putamen had actually gotten smaller.
People who kept practicing maintained their memory performance and didn't experience the same degree of brain shrinkage. Plus, their cerebellums showed more activity across broader areas.
The lead researcher, Kaoru Sekiyama, admitted they were genuinely surprised. Even they didn't expect the effects to be so concentrated in exactly the same brain areas that respond to musical training in younger people.
Why Music Specifically?
I've covered a lot of brain health research, and honestly, there's no shortage of studies saying "do puzzles" or "exercise more." But music seems to hit different.
When you play an instrument, you're not just doing one thing — you're simultaneously:
- Reading music (visual processing)
- Coordinating finger movements (motor control)
- Keeping time and rhythm (internal timing)
- Listening to what you're playing and adjusting (audio feedback)
- Remembering patterns and sequences (memory)
It's like a full-brain workout disguised as something fun. And unlike sudoku or crossword puzzles, there's a physical, sensory element to it that engages even more brain pathways.
"It's Never Too Late"
That's Sekiyama's words, and I love them. Too often, we talk about brain health as if the window for improvement closes at 40 or 50. This research is a beautiful reminder that our brains retain their ability to grow and adapt.
Sekiyama also made a point that I think is incredibly important for public health: music could be a valuable alternative for people who struggle with physical exercise. If chronic pain, mobility issues, or other health conditions make it hard to stay physically active, playing an instrument might offer some of that same protective effect for the brain.
"How fortunate that practicing music has such a positive impact on the brain and cognitive function!" she said.
I'll be honest — when I read that quote, I pictured my dad, who has bad knees and always says he'd exercise more if his body would cooperate. I immediately thought about whether he'd be interested in finally learning that keyboard that's been gathering dust in his spare room.
The Bottom Line
You don't need to become a concert pianist. You don't even need to be good. The people in this study were beginners who kept practicing their instruments over years. That's it.
If you've ever thought about learning an instrument but talked yourself out of it because you're "too old" — consider this your sign. Your brain is apparently ready and waiting.
And if you're caring for an aging parent or grandparent, maybe skip the generic puzzle books this holiday season and consider something a little more melodic.
Your future self (and your putamen) will thank you.
