title: Amplitude-integrated EEG revealed nonconvulsive status epilepticus in children with non-accidental head injury.
abstract: OBJECTIVE
  We describe the clinical course and amplitude-integrated EEG findings in three children with non-accidental head injury and discuss on the importance of continuous aEEG monitoring in infants.
  
  
  METHODS
  NCSE was defined as a continuous 30-min seizure or briefer seizures occurring consecutively comprising at least 30 min of any 1-h period. Non-accidental head injury was diagnosed on the basis of neuroimaging findings such as subdural hemorrhage. Antiepileptic treatment was performed with continuous amplitude-integrated EEG monitoring.
  
  
  RESULTS
  The age of the patients ranged from 48 days to nine months. All of them had loss of consciousness and seizures on presentation. Nonconvulsive status epilepticus without clinical symptoms were recognized in all patients. Vigorous antiepileptic treatment against nonconvulsive status epilepticus was made in two patients, whereas nonconvulsive status epilepticus disappeared within one hour without additional treatment in one.
  
  
  CONCLUSIONS
  Our experience indicates that nonconvulsive status epilepticus were not uncommon in children with non-accidental head injury. Continuous amplitude-integrated EEG monitoring will be one of the useful methods in encephalopathic children in order to estimate seizure burden objectively and to treat seizures appropriately.
