Frightening neurological complications can happen in children who develop a mysterious condition linked to the novel coronavirus COVID-19. A new study says survivors can suffer headaches and muscle weakness, along with visible signs of damage to the brain. According to Gizmodo, the condition is commonly known as multisystem inflammatory syndrome in children, or MIS-C. MIS-C is a rare but potentially life-threatening occurrence that arises during or soon after being infected by COVID-19. Of 27 child survivors who were studied, four showed damage to the brain’s corpus callosum. Interestingly, none of the children reported respiratory symptoms, despite all testing positive for the coronavirus or having antibodies to it.
