If you’ve ever walked into a room and couldn’t remember why you were there; misplaced your keys (or even your car in a parking lot); or forgotten the name of an acquaintance, you might have momentarily wondered about your memory or if you were losing your mind. If you’re over the age of 50, you might even be seriously concerned about the possibility of Alzheimer’s.
It’s a valid concern. According to the 2008 Alzheimer’s Association figures, more than five million Americans over the age of 65 have Alzheimer’s disease. In addition, approximately 500,000 Americans under the age of 65 suffer from Alzheimer’s or other forms of dementia.
Although a decline in memory and brain function is generally regarded as an inevitable part of growing older, in reality, brain aging is caused by poor cerebral circulation, mitochondrial dysfunction, inflammation, oxidative damage, and decreased levels of anabolic-repair hormones, including DHEA and testosterone. All of these factors contribute to changes in the brain that lead to neuronal degeneration and cognitive impairment.
