Herpesvirus Infections May Accelerate Dementia

A new study finds that prior herpesvirus infections are linked to a faster age-related increase in blood biomarkers associated with dementia, even in cognitively healthy women. Researchers measured five key biomarkers in 167 women and found that seropositivity for HHVs doubled the rate of biomarker accumulation compared to those without prior infection.

Cold Sore Virus Linked to Alzheimer’s, Antivirals May Lower Risk

A large study suggests that symptomatic infection with herpes simplex virus 1 (HSV-1)—best known for causing cold sores—may significantly raise the risk of developing Alzheimer’s disease. Researchers found that people with HSV-1 were 80% more likely to have Alzheimer’s, while those treated with antiviral medications had a 17% lower risk.

Link Between Cold Sore Herpes Virus and Alzheimer’s Discovered

Researchers discovered a connection between Alzheimer’s disease and herpes simplex virus-1 (HSV-1), suggesting viral infections may contribute to neurodegeneration. The study found that tau protein, typically seen as harmful in Alzheimer’s, might initially protect the brain from the virus but later exacerbate damage.

Cold Sore Virus’s Path in Brain Revealed

Research has shown that HSV-1, the virus responsible for cold sores, can spread into specific areas of the brain and may contribute to neurodegenerative diseases. Mapping HSV-1’s path reveals it targets regions crucial for functions like sleep, movement, and mood regulation.

Brain’s Defense Mechanism Against Herpesvirus Identified

Researchers have identified a novel defense mechanism in the brain that prevents herpesvirus from causing severe brain infections, despite the virus being present in over half the population. This discovery highlights the protective role of the TMEFF1 gene, which produces a protein that blocks the virus from entering nerve cells. The findings could lead to a better understanding of brain immunity and its role in preventing neurodegenerative diseases like Alzheimer's. This groundbreaking research opens new avenues for studying brain defense mechanisms and their implications for brain health.

Chickenpox Virus May Trigger the Onset of Alzheimer’s Disease

Varicella zoster virus (VZV), the virus that causes chickenpox and shingles, may activate the herpes simplex virus and trigger the onset of Alzheimer's disease, a new mouse study found.

Study Finds Evidence of Possible Link Between Herpes Simplex and Neurogenerative Diseases

Researchers discovered mutations of the OPTN gene resulted in increased herpesvirus 1 growth in the brains of mice, leading to the death of local neurons. This resulted in accelerated neurodegeneration. OPTN deficiency was also associated with impairments in immune response. While these findings are specific to the HSV-1 virus, researchers believe the findings may apply to up to eight herpesvirus infections.

3D brain-like tissue model links Alzheimer’s disease with herpes

A 3D human tissue culture model demonstrated a possible causal relationship between Alzheimer's disease and herpes simplex virus 1 (HSV-1) infection. 40 Alzheimer's associated genes were over-expressed in the HSV-1 infected brain tissue, including genes associated with the production of amyloid-beta.

Does herpes cause Alzheimer’s?

The herpes simplex virus 1, the virus responsible for cold sores, may account for 50% of Alzheimer's disease cases. HSV1 causes protein deposits which are characteristic of Alzheimer's disease. Findings also reveal antiviral treatments can help to reduce the risk of developing Alzheimer's in those with HSV1.
