Details and patient eligibility

About

To date there is no brain imaging and olfactory data available in COVID-19 positive patients with anosmia. By describing the pathophysiological characteristics underlying the olfactory symptoms and clinical characteristics of COVID-19 infection, the study investigators wish to compare the MRI aspects obtained in COVID-19 patients with and without anosmia, in the absence of other underlying neurological disorders.

Full description

Brain mapping of COVID-19 patients with or without anosmia will allow better understanding of the mechanisms leading to the onset of these symptoms and will provide a pathophysiological basis for the therapeutic interventions to improve the clinical prognosis of affected patients.

The study investigators hypothesize that in COVID-19 patients witch anosmia the brain mapping objectified by an MRI examination is modified and that there are functional abnormalities in the brain in these patients.

Inclusion criteria

Consecutive adult patients consulting the CAREB or hospitalized at the Nîmes teaching hospital due to COVID-19 infection (fever, persistent cough, tiredness, shortness of breath, diarrhea, abdominal pain, chest pain, sore throat, loss of smell or taste)
