Can My Brain Still Change at 70?
Short answer
Yes. Your brain can still change at 70.
Your brain at 70 is different from the brain you had at 30. But it hasn’t stopped changing.
Growing older doesn’t stop the brain from responding to new experiences. Older adults can still learn new skills and improve with practice, with measurable changes sometimes appearing in the brain itself. This ability is called neuroplasticity, the brain’s capacity to adapt in response to learning and experience.
That capacity doesn’t disappear with age. But change may take more time, practice and repetition than it once did. The ageing brain is still a changing brain.
What the Research Shows
One of the most encouraging findings from neuroscience is that our brains can still change as we grow older. This ability is called neuroplasticity.
Older adults can still learn new skills, improve specific abilities and show measurable changes in how the brain works. Some studies have even found changes in brain structure.
These changes are usually modest and specific. They don’t mean we can stop brain ageing or that learning something new will prevent dementia.
But they tell us something important: At 70, your brain is still learning, adapting and responding to experience.
Your brain isn’t finished. It is still responding to the life you give it.
One of the most useful studies:
The Synapse Project
Neuroscientist Denise Park and colleagues asked older adults to spend three months learning challenging new skills such as digital photography and quilting.
These were unfamiliar activities that required sustained learning, problem-solving, memory and effort. Participants spent about 16.5 hours a week practising, while comparison groups took part in less demanding activities.
What did they discover?
Those doing the more challenging learning showed greater improvements in episodic memory than those in the less demanding groups.
The important point wasn’t simply to stay busy. It was to give the brain something new and challenging to learn. Keep asking your brain to do things it doesn’t already know how to do.
Then researchers looked inside the brain
A follow-up study used fMRI to see whether the brain itself had changed.
After months of learning challenging new skills, older adults showed changes in brain activity linked to attention and processing meaning. Some of these changes were still present a year later.
So this wasn’t just about feeling mentally sharper. Researchers could see measurable changes in how the brain was working. Evidence confidence: HIGH
Another fascinating example: learning to dance
Researchers studied adults aged 63–80 who joined a dance program where they regularly learned new movements.
After six months, changes were found in a brain region involved in movement. After 18 months, changes also appeared in an area linked to memory.
Dance is interesting because it combines movement, memory, coordination, attention and learning, continually asking the brain to adapt.
The study was small, so we need to be cautious. But it adds to the evidence that the brain can still change in our 70s and beyond.
But there’s an important distinction
Saying “the older brain can still change” is not the same as saying “you can completely rewire your brain at any age.”
Ageing brings real changes. Some thinking becomes slower, certain aspects of memory become more vulnerable, and learning something new may take more time and repetition.
And learning doesn’t always produce measurable changes in brain structure.
In one study, 160 adults aged 65–75 spent 11 weeks learning beginner Italian. They learned the language, but MRI scans didn’t show the structural brain changes researchers were looking for.
So the message is encouraging, but it needs perspective: the ageing brain can still learn and adapt, but its capacity for change isn’t unlimited.
What the Research Suggests
Research suggests that the ageing brain benefits from new and meaningful challenges.
Learning a skill, moving our bodies, staying socially connected and doing things that require attention, effort and practice may help support cognitive function and the brain’s ability to adapt.
That doesn’t mean these activities can prevent dementia or reverse brain ageing.
The message is simpler—and still encouraging:
Ageing changes the brain, but it doesn’t stop the brain from learning, adapting and responding to experience.
What the Research Cannot Tell Us
Research can’t tell us that learning a new skill, doing puzzles or staying mentally active will prevent dementia or reverse brain ageing.
And we won’t all experience the same benefits. Health, genetics, lifestyle and circumstances all play a part in how our brains age.
Even measurable changes in the brain don’t always translate into noticeable changes in everyday life.
The brain can still change as we grow older. It just doesn’t change in the same way, or as easily as it once did.
How Much Difference Did It Make?
The changes were real, but modest. In the Synapse Project, older adults spent about 16 hours a week for three months learning challenging new skills, including digital photography.
Those learning photography showed greater improvement in episodic memory, our ability to remember experiences and events than people doing less demanding activities.
The improvement was measurable, but it didn’t extend to every area of thinking. Learning something challenging made a difference, but not a dramatic one. (PubMed Central (PMC))
The much larger ACTIVE trial followed 2,832 adults who were around 74 when the study began.
People improved most in the abilities they practised. Some improvements in reasoning and processing speed were still detectable 10 years later, although the memory benefits didn’t last as clearly.
The results varied, but some of the benefits of training lasted for years. (PubMed Central (PMC))
Learning something new won’t somehow “rejuvenate” the brain. But the research does show something encouraging: even in our 70s and beyond, the brain can still respond to learning, challenge and practice. The changes may be modest, but they can still make a measurable difference.
What This Means for Everyday Life
You don’t need to spend hours “training your brain.” What matters is giving it opportunities to learn, adapt and stay engaged.
Learn something new. Try a different routine. Move your body. Meet new people. Make something. Follow your curiosity. It doesn’t need to be complicated. What matters is that you’re asking your brain to pay attention, practise or learn.
The goal isn’t to stop your brain from ageing. It’s to keep giving your brain something new to respond to.
Longevity Reimagined Reflection
Growing older changes the brain. But it doesn’t mean the brain has finished changing.
Instead of asking only, “How do I protect the brain I have?” we might ask: “What am I still giving my brain the chance to learn and become?”
What would you try, learn or explore if you didn’t assume you were too old to begin?
Age is information. It isn’t an instruction.

This is the key study for your discussion of learning new and cognitively demanding skills.

This is particularly valuable because the ACTIVE trial included 2,832 adults with a mean starting age of 73.6. Ten years later, reasoning training retained a small effect (0.23), while speed-of-processing training retained a larger effect (0.66); the original memory-training effect was no longer maintained.
