Prolonged Dysphagia After a COVID-19 Infection in a Patient With Parkinson Disease.

Coronavirus disease 2019 might have an impact on patients with Parkinson disease because of the neuroinvasive potential. Herein, we report the case of a patient with Parkinson disease who developed severe and prolonged oropharyngeal dysphagia after a coronavirus disease 2019 infection. A 73-yr-old male patient with Parkinson disease was diagnosed with coronavirus disease 2019 and admitted to a tertiary care hospital. Before hospitalization, he was assessed at Hoehn and Yahr stage 4 and showed no symptoms of dysphagia. After admission, the patient gradually recovered; however, he was fed through a nasogastric tube. A videofluoroscopic swallowing study revealed a severe oropharyngeal dysphagia with a severely delayed oral phase. Therefore, he underwent percutaneous gastrostomy tube insertion. After discharge, although he received swallowing therapy for 4 mos, he still had severe dysphagia, which made him dependent on enteral feeding. We speculate that the impact of coronavirus disease 2019 on dopaminergic and nondopaminergic mechanisms could lead to the development of dysphagia in this patient. The present case suggests that clinicians must have a high index of suspicion without dismissing the possibility of dysphagia and subsequent aspiration pneumonia in coronavirus disease 2019 patients with Parkinson disease.
