Neuroimaging and Transcriptomic Insights Into Iron Accumulation and Glymphatic Dysfunction in Olfactory Dysfunction

Olfactory dysfunction (OD) is clinically linked to inflammation and neurotoxin accumulation, yet the underlying neurobiological mechanisms remain largely unclear. Understanding how glymphatic function, iron dysregulation, and transcriptomic signatures contribute to OD may reveal new biomarkers and mechanisms of recovery.
