First seen Jun 27, 2026 ยท Last updated Jun 27, 2026

Summary

This study collects a small sample of tissue from inside the nose to learn how the sense of smell changes in people with Alzheimer's. Researchers will compare samples from healthy volunteers and those with early or mild Alzheimer's. The goal is to understand the biology behind smell loss, which is an early symptom of the disease.
