Understanding Smell Loss in Older Adults

Olfactory Dysfunction in Aging Adults

NIH-funded research Medical University of South Carolina · NIH-11145909

This project aims to better understand why some older adults lose their sense of smell by looking at different parts of the body involved and how they might be affected.

What this research studies

Many older adults experience a loss of smell, which can impact their health and quality of life. Current methods don't fully explain why this happens or how to group patients based on their specific condition. This work will explore various areas along the smell pathway, from the nose to the brain, to identify distinct ways smell loss occurs. By classifying patients based on these underlying causes, we hope to pave the way for more accurate diagnoses and personalized care.

Who could benefit from this research

Good fit: Ideal candidates for future related studies would be adults aged 21 and older who are experiencing a loss of their sense of smell.

Not a fit: Patients whose smell loss is not related to aging or the specific mechanisms being explored in this foundational research may not directly benefit from this particular effort.

Why it matters

Potential benefit: If successful, this work could lead to improved diagnostic tools and more targeted treatments for older adults experiencing smell loss.

How similar studies have performed: While prior studies have shown that smell loss is common in older individuals, this project takes a novel approach by focusing on classifying patients based on specific disease sites and mechanisms, which has not been comprehensively achieved before.
