A new review of neurological symptoms of COVID-19 patients in current scientific literature reveals the disease poses a global threat to the entire nervous system, reports a Northwestern Medicine study published this week in Annals of Neurology.

About half of hospitalized patients have neurological manifestations of COVID-19, which include headache, dizziness, decreased alertness, difficulty concentrating, disorders of smell and taste, seizures, strokes, weakness and muscle pain.

The disease may affect the entire nervous system, including the brain, spinal cord and nerves as well as the muscles. There are many different ways COVID-19 can cause neurological dysfunction, he said. Because this disease may affect multiple organs (lung, kidney, heart), the brain may also suffer from lack of oxygenation or from clotting disorders that may lead to ischemic or hemorrhagic strokes. In addition, the virus may cause direct infection of the brain and meninges. Finally, the reaction of the immune system to the infection may cause inflammation that can damage the brain and nerves.
