No need for a gym to protect your brain from cognitive decline, another activity accessible to seniors does the job very well according to a study.
According to a study published in the New England Journal of Medicine, regularly practicing this activity after the age of 60 is associated with an up to 76% lower risk of dementia. A striking figure from monitoring carried out over nearly two decades.
The researchers observed adults aged 75 to 85 living at home. Initially, everyone took neuropsychological tests and detailed their lifestyle habits: state of health, leisure activities, physical activity. The objective was to identify, over the long term, behaviors linked to a higher or lower risk of cognitive decline. Overall, the more frequent the stimulating activities, the lower the risk. But one of them clearly stood out.
Participants who reported practicing dance more than once a week had a significantly lower risk than those who practiced it rarely. It is thus the best sport for the brain compared to walking or swimming which also went in a favorable direction, but with a less marked effect. The researchers took into account numerous health and lifestyle parameters to limit bias, and extended follow-up to prevent early cognitive disorders from explaining a reduction in activities.
Why does this practice stand out? Because it simultaneously mobilizes the body and the mind. It’s not just about moving, but memorizing steps, adapting to the rhythm, coordinating your movements, finding your way in space and sometimes interacting with a partner. This combination of physical effort, mental stimulation and coordination creates a complete challenge for the brain. However, these varied challenges could contribute to strengthening the “cognitive reserve”, that is to say the brain’s ability to compensate for the effects of aging.
Another benefit: it improves balance and strength of the lower limbs, two essential elements for preserving autonomy. Since mobility and brain health are closely linked, staying physically and socially active plays a key role in healthy aging. However, we must remain cautious: this research is observational. It highlights a strong association, without demonstrating a cause and effect link. Other factors may be involved.
Nevertheless, these results support the idea that activities combining movement, intellectual stimulation and social interaction are particularly favorable to the brain. Good news: no need to be an expert. Line dancing, ballroom dancing, adapted lessons or simple music at home… The main thing is regularity and pleasure.
