Sniffing Out the Mechanism Behind Parkinson’s Smell Loss

Up to 90% of patients report experiencing a diminished sense of smell, even prior to the onset of other symptoms of Parkinson's disease. A new study reveals the mechanism behind smell loss associated with Parkinson's, reporting mouse models with olfactory impairments had severe pathology in projection neurons of the olfactory pathway. The mice also had reduced neurogenesis in the olfactory bulb.

Inflammation Caused by COVID-19, Rather Than the Virus Itself, May Lead To Loss of Smell

Anosmia, the loss of the sense of smell which is a common symptom of COVID-19, may be a secondary consequence of immune system inflammation rather than a direct action of the virus.
