Cold sores may be tied to memory loss, study suggests By Steve James, NBC News contributor Researchers have found that the virus that causes cold sores, along with other viral or bacterial infections, might be associated with memory loss, and if further studies establish such a link, it could eventually prove helpful in preventing strokes or Alzheimer’s disease. A long-term study of a group of people in one neighborhood of New York City found that those with higher levels of infection in their blood -- meaning they had been exposed to various pathogens such as the herpes simplex type 1 virus that causes cold sores -- were more likely to have cognitive problems than people with lower levels of infection in the blood. The results, released Monday, are published in the March 26 issue of Neurology, the medical journal of the American Academy of Neurology. "While this association needs to be further studied, the results could lead to ways to identify people at risk of cognitive impairment and eventually lower that risk," said Dr. Mira Katan, author of the study. "For example, exercise and childhood vaccinations against viruses could decrease the risk for memory problems later in life.” Katan, who conducted the Northern Manhattan Study at Columbia University Medical Center in New York, is a member of the American Academy of Neurology . The study was performed in collaboration with the Miller School of Medicine at the University of Miami. She said she found the link between infections and memory loss was greater among women, people with lower levels of education and most prominently, in people who do not exercise. The study, performed in collaboration with the Miller School of Medicine at the University of Miami, tested thinking and memory in 1,625 people from northern Manhattan who had an average age of 69. Participants gave blood samples that were tested for five common low grade infections: three viruses (herpes simplex type 1, which is oral; herpes simplex type 2, which is genital; and cytomegalovirus),chlamydia pneumoniae (a common respiratory infection) and Helicobacter pylori (a bacteria found in the stomach).
