When you hear the words “immune system,” you probably think immediately of your body’s defense against seasonal maladies like cold and flu. A strong immune system is definitely an asset in protecting you from these and other invaders. But it turns out the immune system does a lot more than protect against microbes and infection.

A “runner’s high” is a reference to a feeling of euphoria brought on following a strenuous run or even after engaging in other intense forms of exercise. It’s triggered when the brain releases endocannabinoids — fantastic molecules that research shows could be key to giving your memory a boost and even preventing Alzheimer’s.

Since I entered my 60s, my hearing isn’t what it used to be. I find myself asking people to repeat things. They don’t seem to mind and neither do I. After all my hearing is not that bad. But what does bother me is this: Research establishes a firm connection between age-related hearing loss and memory problems, possibly even Alzheimer’s. This is what we can do to combat that threat…

For many, seasonal affective disorder can soon hit hard. The fatigue, sadness, hopelessness and social withdrawal (compounded this year by COVID-19) can make a long winter feel even longer. But if you’re looking for a safe, scientifically-backed way to fend off depression, this fragrant herb can be a big help…

Anticholinergics, also called antispasmodics, treat everything from Parkinson’s to COPD and asthma to irritable bowel syndrome. Some are even found in over-the-counter allergy medications.

But there is another indicator that Alzheimer’s is likely in your future…. one that you can turn around.

The human body was designed to sleep during the night and stay awake during the day. Mixing that up leads to problems. In fact, research shows there may be certain critical functions that your body will only perform during a nighttime sleep session… like clearing all the dementia-causing wastes out of your brain.

As we get older, some vitamins and minerals become especially important. We don’t process them as well and need to get more of them from our diet to protect ourselves from health complications that will make our golden years not so golden.

Diabetes and Alzheimer’s disease often go hand in hand. The evidence for this is becoming stronger. Recently, electron microscopy has enabled scientists to see that amyloid strands that appear in diabetics bear a strong resemblance to the ones that are hallmarks of Alzheimer’s disease.

Despite the fact that cognitive decline is considered a normal part of aging, you’re not doomed to a future filled with “senior” moments. There are ways to slow (or even reverse) the impact aging has on your brain. In fact, science says potent doses of two spices could keep your cognitive skills sharp as a cactus needle…

Part of the reason dementia is so difficult to prevent and treat is that it doesn’t have one cause. It’s caused by a lot of different things. Genetics. Diet. Exercise habits. Pollution. These and many more factors play into your risk of developing this devastating disease. Luckily, new research published in the journal The Lancet […]

When you’re smiling, the whole world smiles with you. Celebrities from Louis Armstrong to Katy Perry have produced hits praising the power of a smile to lift your spirits and make the world a better place.
