THURSDAY, Feb. 3, 2022 (HealthDay News) — Following a bout of severe COVID-19, some children suffer lasting neurological complications, part of a rare condition called multisystem inflammatory syndrome in children (MIS-C), a new study finds.
The neurological symptoms are wide-ranging, and can include headaches, difficulty falling and staying asleep, daytime sleepiness, brain fog, attention difficulties, social problems, anxiety and depression, all of which can persist for weeks to months.
“I see this happen to 10% to 20% of children who have COVID,” said senior researcher Dr. Sanjeev Kothare, director of the division of pediatric neurology at Northwell Health’s Cohen Children’s Medical Center in Lake Success, N.Y.
MIS-C often goes unrecognized, and no specific treatment for it exists, Kothare said. Children are typically treated for specific symptoms and the problems usually go away, but it can take time, he noted.
The best way to prevent your child from developing MIS-C is to have your child vaccinated against COVID-19, Kothare advised.
If, however, your child does develop MIS-C, he recommends that parents should “look out for these symptoms, and if they are present, discuss those symptoms with your provider so that they can give you adequate advice for treatment and decrease the symptoms faster.”
For the small study, Kothare and his colleagues reviewed the cases of 47 children hospitalized for COVID-19.
Among these children, 77% had neurological symptoms, 60% had psychiatric symptoms and 77% had sleep symptoms while hospitalized. Before being hospitalized, 15% of the children had neurological symptoms, none had psychiatric symptoms and 7% had sleep problems.
Twenty to 26 weeks after leaving the hospital, 50% of the children who had neurological symptoms while hospitalized continued to have them. Also, 57% of the children who suffered psychiatric problems continued to have them after leaving the hospital, as did 42% of those who had sleep problems, the researchers found.
All of these problems were more likely to occur in children whose case of COVID-19 was so severe that they had to spend time in the intensive care unit (ICU), the study authors noted.
