Cognitive and Immunologic Profiles of Patients With Olfactory Dysfunction After Smell Training

Summary

A research study to assess the baseline olfactory function, mental health status, clinical severity, and immunological profile in patients with smell loss. The impact of a 3-month olfactory training program on smell function, immunological changes, and mental health in patients with smell loss will be evaluated. The primary purpose of this study is to investigate tissue and blood samples to identify molecules that may be related to smell loss, ultimately aiming to develop future treatments for this condition and correlate with cognition.

Detailed Description

Adult patients with chronic rhinosinusitis (CRS) with nasal polyps and those experiencing loss of smell will be recruited for the study, along with healthy control participants. We will exclude individuals with unilateral nasal polyps, autoimmune diseases, ciliary disorders, cystic fibrosis, or smell loss due to tumors or trauma. Assessments will be conducted at baseline and again three months after smell training to evaluate changes in olfactory function. Control patients will only undergo baseline testing with no follow-up assessments needed.
