Manchester University (United Kingdom) researchers observed that brains infected with the herpes simplex virus, HSV-1, also had elevated levels of the beta amyloid protein characteristic of Alzheimer's disease (AD). Previous research has found that HSV-1 is found in the brains of up to 70% of people afflicted with AD.   Separately, researchers from the University of Rochester Medical Center (New York, USA) found the HSV-1 virus is more likely to cause a problem in people who carry a mutant version of the ApoE4 gene, which is carried by the vast majority of AD patients.

To ward off infectious virus strains, maximize your immune defenses.  Eat a healthy and balanced diet rich in antioxidants, enjoy a few minutes of sunshine daily (or take a Vitamin D supplement), get adequate and quality sleep, exercise regularly, and keep a stress-free, positive outlook on life.
