Cold sores can play a role in the development of Alzheimer’s disease, according to a new study published in BMJ Open.
The researchers examined 344,628 “case control pairs”. Couples were combined with age, sex, geographical region and number of health visits, but one had Alzheimer’s disease and another.
Of the groups studied, 1,507 people with Alzheimer’s also had Simplex Simplex Virus Type 1 (HSV-1), which is the most common cause of cold sores. Only 823 people in the control group had HSV-1.

Among these 2,330 people, 40% used anti-journal medicines after diagnosis.
Those who were treated by the virus had 17% less likely to develop Alzheimer’s disease than those who did not use the treatments, found the study.

It is known that the risk of developing this form of dementia increases with age. However, the possibility of diagnosis of HSV-1 was 80% larger in Alzheimer’s diagnosed, according to the research.
Less usually, cold sores can be caused by the Herpes Simplex Simple 2 virus (HSV-2).

In general, women represent 65% of Alzheimer’s cases. Its average age was 73 years and tended to have more coexisting conditions, which were risk factors.

The study also observed the potential role of other herpes viruses, some of which were associated with a high risk of Alzheimer’s disease.

“However, studies have shown that brain inflammatory alterations caused by VV infection are essential in [Alzheimer’s disease] Development, “they said in the launch.
Antiviric therapy treatment seems to reduce the risk of Alzheimer’s, “suggesting that HSV-1 treatment can be protector,” says the study.

“There is no cure for cold sores, but treatment can help manage outbreaks,” according to the Mayo Clinic.
“Antiviral medicine or recipe creams can help to heal -and they can cause future outbreaks to occur less often and shorter and less severe.”
Potential limitations
There were some limitations in the study, researchers recognized.
“Due to limited data history, HSV-1 infections before the patient’s database entry were not included in the analysis and there may be some overlap between HSV-1 and HSV-2 diagnoses,” said researchers.

“In addition, many people with HSV-1 infection are asymptomatic and others may not look for medical care during recurrences and are not diagnosed and clinically registered in the database.”
Although it is estimated that two thirds of people under the age of 50 are infected with HSV-1, the data on symptomatic infections are limited, “as manifestations can be mild or unnoticed,” added researchers.

The Alzheimer’s Subgnosis could also decrease the results.
