But combining physical activity with creativity and cognitive challenges may help protect the brain further. Dancing asks your brain to do several things at once: match a rhythm, remember steps (or quickly improvise some new ones), navigate space and perhaps even respond to a partner.

While more studies are needed, the data suggest that this degree of cognitive multitasking gives your brain the right kind of workout.

Dancing may also boost balance and strength

Dancing is simply music-based movement – ideally of a kind that makes you feel good and involves the company of others. And it can truly be for almost everyone. In my own clinic, we recommend dancing as therapy for patients with movement disorders like Parkinson’s disease. Even among people who already have dementia, limited studies indicate regular dancing boosts cognitive scores.

Besides brain health, there are other great reasons to consider shaking a hip. A 2020 meta-analysis of 29 randomised trials among healthy older adults found that social dance-based activities were associated with a 37 per cent reduced risk of falling – as well as improvements in balance and lower body strength.

Three simple ways you can become a dancer

• Try something new to find what’s right for you: You might learn that this whole time you thought you had two left feet was simply because you were born to salsa and not Charleston.
• Look for online dance classes: While many community centres offer dance classes specifically for older adults (often free), I know that dance classes suited to your interests and needs are not always easily available nearby. The world of online dance classes blossomed over the pandemic, and, personally, I cannot get enough. Where else would I have found my true calling – modern Bollywood dance classes – but online? There are also several classes on YouTube tailored to possible physical limitations and needs. (As always, check with your physician before starting a new exercise routine.)
• Don’t write off video games: And, of course, let’s not forget video games about dancing. (Who else was a star at Dance Dance Revolution?) Similar games have actually been studied among older adults and found to improve executive function, with effects lasting as long as a year.

Just plain music can help, too

Even if you’re not up for dancing, there’s still power in playing your favourite tunes: A large population study published recently found that just listening to music most days was linked to a decrease in dementia risk.

Music can evoke memory and emotions, but certain kinds of it can also offer a distinctly enjoyable challenge to the brain. As you listen to music, your brain is constantly evaluating its predictions regarding what comes next: Will the next note and beat be the one you’re anticipating?

A potent driver of the urge to groove is syncopation. When music is syncopated – meaning, you expect to hear a loud beat in line with the rhythm, but instead it’s weak, or there’s a quick pulse of silence – it challenges our brain’s expectations.

Syncopation creates an exciting sense of “push and pull” in the music. Humans perceive songs with a healthy dose of syncopations as more pleasurable. Studies have found that those syncopations strongly compel us to bust a move, completing that gap our brain is craving to fill.

What I want my patients to know

There’s no magic bullet to prevent dementia. Cognitive changes are the result of several factors converging in our brains – our genetics, lifestyle, stress, diets and environmental exposures. Walking and other forms of physical activity can help boost your brain health, but doing so shouldn’t feel like a chore. Cognitive strength can also grow out of many activities that give us great joy – moving to music you truly love, sharing space with someone else’s company, and trying something new without worrying how you look doing it.
