Study makes link between herpes:
A childhood virus. Therefore, responsible for fever buttons, could play a major role in the development of Alzheimer’s disease. Similarly, Recent research confirms a hypothesis issued 30 years ago, opening up new prevention avenues.
A study published in 30 years ago in The Lancet relaunch the debate on the link between Herpes Labial and Alzheimer. In addition, Almost all of the population is exposed to the virus of Herpes Simplex 1 (HSV-1)during childhood. For example, This manifests itself in particular by the appearance of fever pimples. However, the virus never leaves the organism and settles in the nervous system. However, In in PreventionDr. Therefore, Linda Yancey, specialist in infectious diseases, specifies that These viruses are “neurotropic”. However, They have the ability to “persist in the nervous system long after initial disease.” This particular nature allows them to reactivate themselves later in life. Similarly, study makes link between herpes in particular In Stress Cas or from drop in immunity. Moreover, This mechanism is also similar to that of the chickenpox virus.
Researchers think that this HSV-1 ability to settle in the nervous system allows it to Cross the blood-brain barrier. Nevertheless, The Bhe is a protective membrane that isolates the brain of the pathogens circulating in the blood. Once inside, the virus can remain dormant. However. according to Ruth Itzhaki, co-author of the original study of 1997, he can “Enter the brain and reactivate” Over time, as the immune system ages and weakens. This reactivation is all the more disturbing since it is suspected of triggering brain inflammation. In the long term, this process could damage the nerve cells irreversibly. Or. “It is now universally accepted that inflammation in the brain is a key step in the development of Alzheimer’s disease,” Recalls Dr. David Hunter, neurologist.
The interaction study makes link between herpes between the virus. the genetic factors
The link between the HSV-1 and Alzheimer’s is particularly strong in people carrying the APOE-E4 gene. Several studies have shown that the presence of the virus. this gene considerably increases the risk of developing the disease. Researchers consider it an important genetic risk factor for Alzheimer’s. However, the exact reasons for this association are not yet fully understood. Dr. Hunter hypothesizes that “The link with the HSV could be that the APOE-E4 impacts the blood-brain barrier. facilitates the entrance to the HSV.”
Laboratory experiences corroborate these observations. Mark Santos. professor of microbiology, underlines: “Laboratory studies have also shown that HSV-1 infection can trigger the accumulation of amyloid-bêta and Tau”. The aggregation of these two proteins is is a characteristic marker of Alzheimer’s. These results were a major turning point. They made it possible to move from a simple statistical correlation to a more concrete study makes link between herpes understanding of the biological. mechanisms in play. The detection of viral DNA of the HSV-1 inside the aggregates of these proteins in the brain of patients. with Alzheimer still reinforces this hypothesis.

Preserve your immune system and brain at the same time
The demonstration of this viral link opens the door to new strategies for the prevention and treatment of Alzheimer’s disease. Epidemiological data already seem to support this theory. Several studies have shown that vaccination against various infections. such as influenza or COVID-19, is associated with a reduced risk of developing the disease. These discoveries suggest that it is possible to prevent disease by reducing the frequency and severity of infections. In France, it is estimated that more than study makes link between herpes a million people have Alzheimer’s. This number should double by 2050, according to forecasts. Faced with these figures, research is more crucial than ever.
The link between HSV-1 and Alzheimer remains a research subject. However, it is important to note that good lifestyle can already help reduce risks. L’Regular physical exercisea healthy food for the heartthe stimulation mentale et Stopping smoking are tracks. They can “Drastically reduce the risk” De Dément underlines Dr. Yancey. By supporting the health of the brain and the immune system, everyone can take for their cognitive health.
