A new study from researchers at the University of Texas Medical Branch has found that individuals with a history of herpes simplex virus (HSV) infections face a significantly higher risk of developing dementia, including Alzheimer’s disease. The findings, published in the Journal of Alzheimer’s Disease, highlight a critical link between HSV-1, which primarily causes oral herpes, and HSV-2 infections, which cause genital herpes, and neurodegenerative disease progression.
