Diagnosing hyperkinetic seizures in children can be challenging due to their intense motor activity. Video-electroencephalography (EEG) monitoring is crucial for accurate diagnosis of these complex partial seizures.

Area of Science:

  • Pediatric Neurology
  • Epileptology

Background:

  • Complex partial seizures in children can present with intense motor activity, mimicking nonepileptic events.
  • Hyperkinetic seizures, characterized by vigorous limb and trunk movements, pose diagnostic challenges.

Purpose of the Study:

  • To describe the clinical and video-electroencephalography (EEG) features of children with hyperkinetic seizures.
  • To highlight the diagnostic utility of video-EEG in differentiating these seizures from pseudoseizures.

Main Methods:

  • Retrospective review of clinical data and video-EEG monitoring in five children diagnosed with hyperkinetic seizures.
  • Analysis of semiology, interictal and ictal EEG findings, and neuroimaging.

Main Results:

  • Five children (3 boys, 2 girls; mean age 10 years) were diagnosed with hyperkinetic seizures.

  • Seizures involved stereotypic intense motor activity, screaming, and intense fear; two progressed to tonic-clonic seizures.
  • Video-EEG, despite electromyographic (EMG) artifact, confirmed seizure patterns or postictal slowing in all patients.

    • Conclusions:

    • Hyperkinetic seizures require careful evaluation due to overlap with nonepileptic events like parasomnias and pseudoseizures.
    • Video-EEG monitoring is the definitive method for diagnosing hyperkinetic seizures in children.
    • Seizure control was achieved in most patients, with one diagnosed with autosomal dominant nocturnal frontal lobe epilepsy.
