NCT ID NCT05881239
First seen Mar 07, 2026 · Last updated May 13, 2026 · Updated 8 times
Summary
This study explores whether a simple, at-home smell test can help detect early signs of Alzheimer's and other brain diseases. Researchers will ask 250 adults with mild memory or behavior concerns, as well as healthy older adults, to take a 45-minute smell test using scratch-and-sniff cards and a phone app. The goal is to develop a low-cost, noninvasive tool to tell the difference between normal aging and early disease.
