The onset of functional movement disorders after COVID-19: A case series

Patients with post-acute sequelae after coronavirus disease (COVID-19) report a variety of non-specific neurological complications (e.g., myoclonus, limb weakness). In particular, they manifest scenarios as medically unexplained symptoms and are known as functional movement disorders (FMDs). We present three cases of FMDs in patients of the Institute of Clinical Medicine named after N. V. Sklifosovsky (Sechenov University). All patients had a history of COVID-19 infection and reported fatigue, weakness, and jerks of upper and lower limbs. In conclusion, there might be a major possibility of the virus negatively affecting the central nervous system, including such rare neuropsychiatric complications.
