Nose Swab Offers Early Glimpse of Alzheimer’s Risk
TL;DR Summary
Researchers developed a nasal swab test that analyzes living smell-detecting nerve cells to detect Alzheimer’s-related brain changes before cognitive symptoms appear. In a small study of 22 participants, patterns distinguished those with early Alzheimer’s from healthy individuals, suggesting the swab measures neural and immune activity earlier than blood tests and could help diagnose and monitor treatment in larger future trials.
