A new study reveals a potential link between herpes simplex virus (HSV-1) and Alzheimer's disease. The research suggests that HSV-1 may accelerate neurodegeneration in individuals with Alzheimer's.
New research has revealed a worrying link between Alzheimer's disease and a common sexually transmitted infection ( STI ). The study, led by the Hebrew University of Jerusalem, used advanced technologies to identify 'HSV-1 related' proteins in the brains of individuals with Alzheimer's . These proteins are specifically associated with herpes - a virus spread through vaginal, anal and oral sex that can cause a range of uncomfortable symptoms.
Alarmingly, the team discovered that the STI could potentially cause 'more harm' and 'accelerate neurodegeneration' among people with Alzheimer's. This is particularly concerning given that seven out of every 10 people have contracted the herpes virus by the age of 25 in the UK, according to NHS statistics. Lead author, Dr Or Shemesh, explained: 'Our research shows how HSV-1 interacts with the brain and influences the pathologies of Alzheimer’s disease. 'Early on, the changes in tau may protect brain cells by limiting the virus, but as the disease advances, these same changes could lead to more harm and accelerate neurodegeneration.' While further research is required to fully understand why this is, Dr Shemesh's findings suggest that immune system responses may be linked with cognitive decline. At present, there are no known cures for either Alzheimer's or herpes, although various treatments and medications can alleviate symptoms of both. Alzheimer's is the most common form of dementia, characterised by a decline in brain function, while herpes typically presents more physical symptoms. These can include small blisters around the genitals, mouth, thighs, anus or bottom, tingling around the genitals, pain when urinating and unusual discharge. The NHS explains: 'Go to a GP or sexual health clinic if you've been diagnosed with genital herpes and need treatment for an outbreak. 'Antiviral medicine may help shorten an outbreak by 1 or 2 days if you start taking it as soon as symptoms appea

Gut Infection Linked to Alzheimer's Disease in SomeResearchers at Arizona State University and Banner Alzheimer's Institute have discovered a potential link between a chronic gut infection caused by cytomegalovirus (HCMV) and the development of Alzheimer's disease in a subset of people. The virus, which most humans are exposed to early in life, may remain active in the gut and travel to the brain via the vagus nerve, potentially changing the immune system and contributing to Alzheimer's-related changes. The researchers are developing a blood test to identify people with active HCMV infections who might benefit from antiviral medication.
