Summary: The article discusses a growing scientific interest in the potential link between viruses and Alzheimer's disease. Some scientists propose that viruses, particularly herpes simplex virus 1 (HSV1), might trigger Alzheimer's disease. This theory challenges the long-standing focus on amyloid and tau proteins as the primary cause of Alzheimer's. The viral theory opens up new treatment possibilities, including antivirals and vaccines. A clinical trial testing the effectiveness of an antiviral treatment against dementia is underway, with results expected later in 2025.
