    Olfactory dysfunction (OD) is increasingly recognized in neurodegenerative diseases and COVID-19, with a prevalence of approximately 22% in the general population.

  • 2

    The USA leads in research output on OD mechanisms, with significant contributions from the University of California System and author Thomas Hummel.

  • 3

    Key research topics include COVID-19, Parkinson’s disease, inflammation, and odorant receptors, indicating current trends in OD studies.

  • 4

    The study identified 14 interventional clinical trials focusing on pharmacological and non-pharmacological approaches to address OD.

  • 5

    Research on OD is shifting from broad observations to detailed molecular mechanisms, emphasizing the role of inflammation and neuroregeneration.
