COVID-19 Linked to Neurological Disorders and Increased MS Disability.

Patients with functional neurological disorder (FND) after COVID-19 infection had different symptoms than people with FND after COVID-19 vaccines, according to a retrospective study. Those with FND after COVID-19 vaccination more closely resembled classic FND, while those with post-COVID FND tended to be older, had more insidious onset, and had higher disability. The findings point to a need to consider FND when diagnosing patients with post-COVID neurologic symptoms.
