Nose Swab Offers Early Glimpse of Alzheimer’s Risk

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.

Nose swabs could flag Alzheimer's earlier, Duke study suggests

Duke researchers are testing whether a nasal swab taken from the back of the nose, using an endoscope and a small brush, can reveal early brain changes linked to Alzheimer's—potentially offering a less invasive and cheaper alternative to lumbar punctures or amyloid PET scans. While promising, the approach is in early stages, but if validated it could speed diagnosis and hasten the use of new disease-modifying therapies, easing the burden on patients and families.
