Olfactory Bulb MRI and Paranasal Sinus CT Findings in Persistent COVID-19 Anosmia

Sedat Giray Kandemirli et al.

Summary: This study evaluated 23 patients with persistent COVID-19 olfactory dysfunction, finding olfactory cleft and olfactory bulb abnormalities to be common in cases of COVID-19 anosmia. The study also revealed a relatively high percentage of olfactory bulb degeneration, indicating a need for further longitudinal imaging studies to better understand the mechanism of olfactory neuronal pathway injury in COVID-19 anosmia.

Changes of olfactory tract in Parkinson's disease: a DTI tractography study

Pasquale Nigro et al.

Summary: This study utilized diffusion tensor imaging to analyze the olfactory tract in Parkinson's disease patients, revealing significant decreases in fractional anisotropy and tract volume in the Parkinson's disease group compared to controls. These findings help characterize hyposmia in Parkinson's disease.

The temporal course of COVID-19 anosmia and relation to other clinical symptoms

Aytug Altundag et al.

Summary: This study aimed to investigate the clinical course of anosmia in relation to other symptoms among COVID-19 patients. The results showed that isolated anosmia cases had more severe symptoms and lower complete recovery rates compared to patients with other clinical symptoms. Residual olfactory dysfunction and duration of loss of smell varied between different groups.

Structural and metabolic brain abnormalities in COVID-19 patients with sudden loss of smell

Maxime Niesen et al.

Summary: This study found that sudden loss of smell in COVID-19 patients is associated with metabolic abnormalities in core olfactory and high-order cortical areas, likely related to processes of deafferentation and lack of olfactory stimulation.

Summary: The study describes cranial nerve lesions in six confirmed COVID-19 cases seen on MRI, indicating a possible autoimmune cause due to the absence of the virus in the cerebrospinal fluid and the development of neurological symptoms after initial respiratory symptoms.

Martin Sylvester Otte et al.

Summary: The study aimed to investigate the improvement of olfactory function in patients with impaired olfactory function detected in a validated olfactory test 3 months after COVID-19 disease, and found that 96% of patients showed improvement in olfactory function after 6 months with all measured subitems significantly improved.
