Have doctors found the key to diagnosing long COVID?
In their case report, US doctors say a brain PET scan could be key to confirming the common condition
Brain PET scans could be a useful screening test for post-acute COVID-19, according to US doctors in a case report of a patient who had persistent symptoms for nine months.
The middle-aged patient who was finally found to have long COVID — estimated to affect 10-30% of people infected with SARS-CoV-2 — contracted the virus at work in December 2020.
She was prescribed a three-week course of dexamethasone for symptoms including fever, dyspnoea, cough, anosmia, fatigue and dysgeusia, as well as rhinorrhoea and left eye pain similar to sinusitis.
Since then, she had continued to experience anosmia with the addition of parasomnias of burning or foul odours, said the doctors from the Mayo Clinic in Rochester, Minnesota.
