  • Seizure type may include generalized tonic-clonic seizures, partial seizures, and infantile spasms. Of note, about 13% of children with DS and no clinical seizures have EEG abnormalities that may complicate interpretation.[medicalhomeportal.org]

Workup

  • Any signs of developmental regression should be regarded as a medical emergency and an urgent medical workup is indicated.[learn.pediatrics.ubc.ca]
