By age 40, about two-thirds of all people experience some mental decline, which can accelerate with each decade of life. The longer you’ve lived, the more likely it is that your brain will be damaged by free radicals and inflammation, and the more likely you are to see a decrease in mental function. The downward spiral begins with the typical mild memory problems or brain fog so common in midlife and can accelerate exponentially with each decade. By age 65, 1 out of 100 people will have symptoms of dementia, such as confusion, severe forgetfulness, and an inability to manage on their own. There are some solid memory improvement techniques that can help with this.By age 75 this is true for 1 out of 10, and by age 85, 1 out of 2. If you don’t stop the spiral, you can go from not remembering where you put your keys to not knowing how to use your keys.

Clearly, age plays a role in brain and neurological function, but these statistics don’t tell the whole story. When it comes to impaired brain function, age alone is not the primary culprit. Simply growing older doesn’t mean that you will grow frail in body and mind. If you are free of other risk factors, it is possible to maintain maximum brain function at any age. Your health and lifestyle are far more important in terms of assessing your risk of neurological problems than your age. On the Brain Audit, a healthy octogenarian can score in the low-risk range if he or she does not have any other risk factors other than advanced age, while a much younger person with a risky lifestyle and/or medical problems can score in the high-risk range.
