This study describes benign complex partial seizures in nine infants, characterized by motion arrest and automatisms. Seizures were easily managed with medication, with all infants remaining seizure-free for over three years.

Area of Science:

  • Pediatric Neurology
  • Epilepsy Research
  • Clinical Neuroscience

Background:

  • Benign complex partial seizures in infants are a distinct epileptic syndrome.
  • Accurate diagnosis is crucial for appropriate management and prognosis.

Purpose of the Study:

  • To describe the clinical characteristics and diagnostic features of benign complex partial seizures in a cohort of nine infants.
  • To evaluate the efficacy of specific antiepileptic drugs in managing these seizures.
  • To assess long-term outcomes, including seizure recurrence and developmental status.

Main Methods:

  • Simultaneous electroencephalogram (EEG) and video recordings were used for diagnosis.
  • Infants were monitored for seizure presentation, including motor arrest, altered responsiveness, and automatisms.

  • Treatment efficacy was assessed using carbamazepine and phenobarbital.
  • Long-term follow-up included seizure status and psychomotor development assessment.

    • Main Results:

    • Nine infants diagnosed with benign complex partial seizures were identified.
    • Seizures presented as clusters of motion arrest, decreased responsiveness, staring, and simple automatisms, often with mild convulsive movements.
    • Focal paroxysmal discharges were observed on EEG.
    • Carbamazepine or phenobarbital effectively controlled seizures in all patients.
    • All patients remained seizure-free for over three years.
    • Four patients had a family history of benign infantile convulsions.
    • Interictal EEG and psychomotor development remained normal in all patients.

    Conclusions:

    • Benign complex partial seizures in infants represent a distinct, treatable epilepsy syndrome.
    • Early diagnosis via simultaneous EEG-video monitoring and prompt treatment with carbamazepine or phenobarbital leads to excellent long-term seizure control.
    • Normal interictal EEG and psychomotor development suggest a favorable prognosis for these infants.
