Dementia is one of the greatest fears of aging, but the idea that cognitive decline is inevitable is wrong. There’s no such thing as “senior moments”—these are early signs of brain decline that should be addressed. Your brain can stay sharp and fully functional for your entire life if you act early and have a brain-health plan in place. Don’t accept brain decline as normal due to age. By taking action at the first signs of trouble, you can ensure a high-functioning brain until your last breath.
