Post-acute COVID-19 functional movement disorder.

Movement disorders are rare compared to other neurological manifestations of COVID-19. Patients who have recovered from acute severe acute respiratory syndrome coronavirus-2 infection continue to have multiple debilitating symptoms months later. We report a case of 54-year-old man who presented with repetitive flexion movement of head which started 2 months after severe acute respiratory syndrome coronavirus-2 infection. Extensive work-up including neurological examination, neuroimaging, cerebrospinal fluid analysis, and electroencephalogram were normal. The self-reported questionnaires for depression and anxiety were suggestive of severe anxiety and depression. The patient continued to have the jerky movements besides cognitive impairment, frequent headaches, intermittent shortness of breath, sleeping difficulties, fatigue, and dizziness at 1-year follow-up. This case highlights the presentation of functional movement disorder as one of the manifestations of underlying neuropsychiatric condition. Our patient had significant effect on quality of life with high symptom burden which further highlights the struggle and unmet needs of the patients with multiple symptoms after severe acute respiratory syndrome coronavirus-2 infection.
