According to recent Research symptoms appearing on the lips may potentially signal an increased risk of dementia. This one The viral symptom is associated with an 80 percent increase in the risk of Alzheimer’s disease, informs about it
A study published in British Medical Journal suggests that Herpes simplex virus type 1 (HSV-1), a common virus responsible for herpes and cold sores, may contribute to Alzheimer’s disease. While previous studies indicated the link between HSV-1 and Alzheimer’s disease, the aim of this research was to investigate this connection deeper.
As part of the study, researchers analyzed medical records of more than 300,000 people aged 50 years or more. As Surreyliva informed, The participants were divided into two equal groups, distinguishing among those who were diagnosed with Alzheimer’s disease and those who did not diagnose it.
Alzheimer’s Research described in detail how the study found that 1507 (0.44 percent) of participants diagnosed with Alzheimer’s disease had a history of HSV-1 infection compared to 823 (0.22 percent) participants without the diagnosis of Alzheimer’s disease. In conclusion, individuals with HSV-1 had 80 percent higher risk of Alzheimer’s disease.
The theory has also been confirmed, taking into account other factors, such as carriers of two copies of the APOE4 gene, a known risk factor for Alzheimer’s disease. In addition, it was found that individuals who have been prescribed virus treatment drugs were 17 percent less likely to develop Alzheimer’s disease compared to those who did not take any medicines.
Is necessary to consider some restrictions on this study. “Despite a large sample, this research is based on the information obtained from the use of medical records and administrative data on claims that often assume that people themselves report their illnesses,” stressed Dr. Sheona Scales, Research Director at Alzheimer’s Research UK.
„Most people infected HSV-1 have no symptomsso some infections may not be recorded. Infections older than recorded information are also not available. Although cases have been compared to the control group, the diagnosis of Alzheimer’s disease, especially in the early stages, remains a challenge, ”says the doctor.
Although HSV-1 is common, infection is not guaranteed by the virus that Alzheimer’s disease develops in the individual. The exact relationship between HSV-1 and the increased risk of Alzheimer’s disease is still subject to examination Current hypotheses suggest that infections can trigger brain inflammation, which can lead to damage.
“We know that There are 14 risk factors for lifestyle -related dementia, and there is not enough evidence to include infections in this list. This study does not tell us whether infections cause risk, only shows a link. Further research is needed to understand the basic biology of this phenomenon, “said Dr. Scales.
