Blast from the Past

As we age, our brain’s ability to process information with speed and efficiency steadily declines. But a new study shows that higher levels of fitness can curb cognitive decline in older adults by increasing the volume of key parts of the brain, especially those responsible for reasoning and problem solving. These results suggest that we can improve our brain health by changing our lifestyle even as we age.

I’ve said it before: poor cognitive function as we get older is not inevitable. If you want to age well, minimize neurodegeneration and protect against common (but not normal) conditions associated with aging, you need to take matters into your own hands.

Exercise is one of the key strategies for keeping your brain sharp as you get older. I’ve outlined other strategies in this post from way back in 2011, nearly all of which are a component of my healthy lifestyle program 14Four. There’s no reason to expect significant cognitive decline as you age, and it’s important to make these lifestyle changes well before your cognitive function is even an issue.
