Insights

Multisystem inflammatory syndrome in children (MIS-C) often causes neurological symptoms. Electroencephalographic abnormalities were found in 28.6% of MIS-C patients, indicating a need for neurological monitoring.

Area of Science:

  • Pediatric Neurology
  • Infectious Diseases
  • Neurophysiology

Background:

  • Multisystem inflammatory syndrome in children (MIS-C) is a post-COVID-19 condition with diverse symptoms.
  • Neurological manifestations are common in MIS-C, necessitating further investigation.
  • Electroencephalography (EEG) is crucial for assessing neurological function in affected children.

Purpose of the Study:

  • To evaluate electroencephalographic (EEG) findings in children with MIS-C.
  • To compare neurological manifestations and EEG results between MIS-C patients and healthy controls.
  • To determine the significance of EEG abnormalities in MIS-C and their correlation with neurological deficits.

Main Methods:

  • Retrospective analysis of 70 children diagnosed with MIS-C between March 2020 and 2022.
  • Collection of demographic data, clinical complaints, and neurological examination findings.
  • Performance of baseline and follow-up electroencephalography (EEG) and cranial magnetic resonance imaging (MRI) for selected patients.

Main Results:

  • Neurological symptoms were present in 72% of MIS-C patients.
  • EEG abnormalities, including generalized and focal paroxysmal activity, were detected in 28.6% of patients.
  • Abnormal EEG findings correlated with neurological manifestations in 12 out of 20 affected patients, regardless of MRI results.

Conclusions:

  • EEG abnormalities are significant in children with MIS-C, even in asymptomatic cases.
  • Close neurological monitoring, including EEG, is essential for managing MIS-C patients.
  • These findings contribute to understanding the neurophysiological impact of MIS-C.
