Photosensitive epilepsy (PSE) in children can manifest in various seizure types, often triggered by visual stimuli like flickering lights. Early onset PSE (≤7 years) is linked to intellectual deficits and intractable seizures.

Area of Science:

  • Pediatric Neurology
  • Epileptology
  • Clinical Neurophysiology

Background:

  • Photosensitive seizures (PSS) represent a distinct subtype of epilepsy characterized by visually triggered episodes.
  • Understanding the clinical spectrum and long-term outcomes of PSS in pediatric populations is crucial for effective management.

Purpose of the Study:

  • To retrospectively analyze the clinical characteristics, seizure types, and outcomes of children diagnosed with photosensitive seizures.
  • To investigate the relationship between the age of epilepsy onset and the presence of intellectual deficits in children with PSS.

Main Methods:

  • Retrospective analysis of 17 children with PSS followed for a mean of 9 years.
  • Verification of PSS using simultaneous video-electroencephalogram (EEG) monitoring.

  • Classification of seizure types and epileptic syndromes according to established criteria.

    • Main Results:

    • Common triggers included flickering stroboscopes (14 patients) and self-induction (3 patients) through actions like head-nodding or blinking.
    • Seizure types varied, including myoclonic seizures (8), generalized tonic-clonic convulsions (5), partial seizures (3), and atypical absence (1).
    • Children with epilepsy onset at age 7 or younger were more prone to intellectual deficits and intractable seizures.

    Conclusions:

    • Photosensitive epilepsy in children presents with diverse seizure manifestations and triggers.
    • Early-onset PSS is associated with significant comorbidities, including intellectual deficits and treatment resistance.
    • Further research is needed to optimize management strategies for pediatric PSS.
