A study of nearly 10,000 people found that among adults ages 60–65, those with a slower gait were 52% more likely to develop dementia, while those with impaired balance were 58% more likely. When both were present, the risk was two to three times higher.
Why might mobility, sensory function, and dementia be so closely connected?
There are a few possibilities. Sensory loss and reduced mobility may contribute to changes in the brain that increase dementia risk. The brain may also have to work harder to compensate for impaired vision, hearing, or balance, creating greater cognitive load.
And there’s another important piece: when it becomes harder to move around or engage with the world, people may become more socially isolated, less physically active, and less cognitively stimulated—all of which can affect brain health. The relationship may ultimately go both ways, with some of these factors sharing underlying causes.
Strength training, balance exercises, regular movement, and addressing changes in hearing or vision (as discussed in a previous video) are all meaningful ways to support healthy aging.
