New cases of dementia are estimated to double by 2060, but the good news is that about 45 percent of those cases may be preventable by making lifestyle changes known to help preserve memory or cognitive function in general.
Last year, a clinical trial found that a mix of exercise, a healthy diet, social engagement and brain games could improve cognitive capabilities in older adults at risk of cognitive decline or dementia. Other studies have found that eliminating alcohol, getting regular vaccines, and even singing and taking naps can affect our brain health.
