A study suggests that the Human Pegivirus (HPgV), previously considered harmless, may be linked to Parkinson's disease, as it was found in the brains of patients but not in healthy individuals, indicating a potential environmental factor influencing the disease's development.
A recent study suggests a potential association between herpes simplex virus type 1 (HSV-1) and Alzheimer's disease, indicating that HSV-1 infection may increase the risk of developing Alzheimer's, but it does not establish causation. The research highlights the need for further investigation into viral contributions to neurodegenerative diseases, while emphasizing that most HSV-1 carriers do not develop Alzheimer's and that maintaining overall brain health is crucial.
