Would You Like a Nasal Swab for Alzheimer's Disease?
A new nasal‑swab assay claims to identify Alzheimer’s‑related biomarkers before cognitive symptoms appear, based on a small study of 22 volunteers. The test emerges amid growing scrutiny of the amyloid‑centric model, which was shaken in 2022 when the seminal paper underpinning two decades of drug development was alleged to be fraudulent. Researchers are increasingly exploring an infectious hypothesis that positions pathogens as triggers for amyloid deposition. If validated, the swab could shift early‑diagnosis strategies and challenge industry focus on vaccine‑centric solutions.
