Current dementia news: virus found in senior citizens’ brains! Does Herpes Cause Alzheimer’s?

How does Alzheimer’s develop? Researchers do not yet have a clear answer to this question. However, the latest research results suggest that herpes viruses can increase the risk of developing this form of dementia.

It has been suspected for a long time that the herpes simplex virus type 1 (HSV-1) is responsible for the development of Alzheimer and other forms of dementia could favor. In a 30-year research project, a research team took a closer look and discovered a possible connection.

New Study: Herpes Infection Increases Alzheimer’s Risk

Researchers from the Oxford Institute of Population Aging, Tufts University in the US and the University of Manchester discovered HSV-1 in many of the brains of elderly people. They also found more abnormal tau proteins than in people who didn’t deal with it Herpesvirus infected. It is already suspected that these malformed tau proteins could promote Alzheimer’s. Proteins are microscopic tubes. Through them, nutrients can be transported to the different areas of the brain. However, if these tau proteins are formed incorrectly, the brain is no longer sufficiently supplied with vital substances. How high the risk of the virus-related malformation is is shown by the cold sores. The more of them appear on the skin, lips or in the genital area, the higher the risk of developing Alzheimer’s.

Current dementia news: Shingles can damage the brain

Shingles (herpes zoster) also plays a role. “Our results are consistent with the assumption that shingles causes reactivation of HSV-1 in the brain,” write the researchers, in which “Journal of Alzheimer’s DiseaseProfessor Itzhaki, Visiting Professor at the Oxford Institute of Population Aging, said: “This remarkable finding seems to confirm that infections such as VZV in humans can lead to an increase in inflammation in the brain that can reactivate dormant HSV-1.” , The Sun quotes Ruth Itzhaki, visiting professor at the Oxford Institute of Population Aging, who added: “Damage to the brain from repeated infections throughout life would eventually lead to the development of Alzheimer’s or dementia.” reduce viral damage and thus also indirectly offer some protection against Alzheimer’s”.

Shingles is caused by the varicella-zoster virus (VZV). This gets into the body after a chickenpox infection, where it can lie dormant for years. Especially older people or people with a weakened immune system who have once had chickenpox can get shingles. Complications such as a heart attack, stroke, neurological disorders such as meningitis, or chronic nerve pain (post-herpetic neuralgia) are possible in patients with herpes zoster. To prevent this from happening in the first place, doctors recommend vaccination.
