Alzheimer's cold sore virus link

New evidence has shown a correlation between cold sore sufferers and patients dealing with Alzheimer's. Researchers studied cells in culture infected with the virus, and found a dramatic increase in the production of beta amyloid protein, a building block for the plaques that are present in those who suffer from Alzheimer's. Further studies have shown that the herpes simplex virus is found in the brains of up to 70% of people with Alzheimer's. This disease is caused by several factors; still, this information offers new hope in finding a way to prevent the onset of the disease.
