In the wake of the COVID-۱۹ pandemic, anosmia, the loss of the sense of smell, has emerged as a curious and widespread symptom. While the sense of smell in many individuals has eventually recovered, some grapple with anosmia for extended periods. In our recent study entitled "Magnetic Resonance Spectroscopy Findings of Brain Olfactory Areas in Patients With COVID-۱۹-Related Anosmia," we embarked on a journey to explore the neurochemical underpinnings of anosmia in COVID-۱۹ patients. This commentary extends our original research, providing insights into the evolving landscape of COVID-۱۹-related anosmia and its implications.
