I have spoken at length about the importance of exercise for increasing the gene expression of BDNF, a protein that increases the growth of new brain cells. As previously mentioned, research has shown that people with higher levels of BDNF are at a lower risk of developing dementia.
In this new study, exercise in people age 50 or over is demonstrated to have significant effects on cognition. The report is a meta-analysis, meaning a review of other research publications (in this case, 39 studies). It’s a comprehensive look at how exercise impacts the brain!
These days it’s pretty common knowledge that we humans are constantly replenishing our brain cells, a process known as neurogenesis. But keep in mind that the first scientific publication that demonstrated our capacity to grow new brain cells was only recently published, in 1998. To be sure, back when I was in medical school in the early 1980s, it was pretty much accepted as dogma that humans totally lacked this ability. We were told that you had a given number of brain cells and that after around age 18, it was pretty much downhill from there.
Neurogenesis, growing new brain cells, is happening in your brain right now, and this process will continue for the rest of your life. But the revelation is that we can actually enhance this process by making smart lifestyle choices. Continue reading
When you survey people to determine what diseases they fear the most, Alzheimer’s is always among the top answers. Its been estimated that in America today there are approximately 5.4 million of us who’ve been given this diagnosis. To call it like it is, Alzheimer’s is a disease for which there is no meaningful treatment, whatsoever.
But what if medical researchers could identify some sort of treatment or intervention that could conceivably reduce a person’s chances of developing this incurable condition? What if there was a way that you could reduce your odds of this most common form of dementia by half?
As it turns out, top-notch researchers have just identified a supplement that does just that, and the name of this supplement you are going to want to make a part of your daily routine is: exercise. Continue reading
