Half of all children who develop the rare inflammatory condition linked to COVID-19 have neurological symptoms or signs, a new study suggests. Researchers looked at youngsters diagnosed with multisystem inflammatory syndrome in children (MIS-C), a condition in which different body parts become inflamed. The most common symptom was headache, but children could also develop more serious side effects such as hallucinations or seizures. The team, says the findings show why it's important for doctors to carefully monitor pediatric patients with COVID-19 to see if they develop any of these worrying signs. MIS-C was originally thought to be linked with Kawasaki disease. The majority of children and adolescents develop MIS-C between two and four weeks after being infected with the coronavirus. Not every child who has developed the condition has tested positive for coronavirus, but 98 percent have - enough for doctors to believe the conditions are linked. The team looked at records of children under age 18 admitted to Great Ormond Street Hospital in London between April 4 and September 1 of last year. Of the children, with an average age of 10, there were 46 who met the criteria of MIS-C. Results showed that 24 children had neurological symptoms with the most common being headaches - affecting all of the pediatric patients. Fourteen children had encephalopathy, which is damage that affects the brain; six had voice abnormalities or hoarseness; and six had hallucinations. Five of the children had ataxia, or impaired coordination; three had problems with their peripheral nerves; and one child had seizures. Patients with these symptoms are more likely to need a ventilator or drugs to stabilize their conditions, but researchers found no differences in short-term outcomes.
