Exercise and Dementia: Preventing Cognitive Decline
As we age, our cognitive functioning declines. Cognitive functioning includes several mental abilities, like thinking, reasoning, remembering, attention, and problem-solving. A normal decline in cognitive functioning can make us more forgetful. Or it could take us longer to solve difficult problems.
But these can also be signs of dementia or Alzheimer’s. By 2050, it’s expected more than 115 million people worldwide will have dementia.

At UVA Health, our geriatric care providers are experts in helping older adults stay healthy.
The study followed 62,000 adults who were 65 or older. It found small amounts of light-intensity exercise lowered the risk of dementia by 14%. The exercise included an 18-minute daily walk or an hour of golf once a week.
Exercise also keeps the brain sharper, according to another study. For every flight of stairs a person climbed daily, their physical brain age was half a year younger. They used MRI to measure brain age.
Other studies show exercise helps with preventing dementia by boosting memory and thinking. Regular aerobic exercise increases the size of the hippocampus. This part of the brain controls verbal memory and learning. Exercise also reduces inflammation in the brain. It makes the brain release chemicals that make the brain healthier.
