Video games can trigger epileptic seizures, particularly in individuals with idiopathic generalized epilepsy. Management should consider both photosensitivity and non-photic factors, as well as seizure type.

Area of Science:

  • Neurology
  • Epileptology
  • Neurophysiology

Background:

  • Epileptic seizures can be provoked by various stimuli.
  • Video game playing has been anecdotally linked to seizure occurrence.

Observation:

  • Fifteen new cases of video game-associated seizures are presented, alongside a literature review of 20 additional cases.
  • The majority of patients experienced their first seizure while playing video games.
  • Common seizure types included generalized tonic-clonic, absence, and myoclonic seizures, often associated with idiopathic generalized epilepsy.

Findings:

  • Photosensitivity to intermittent photic stimulation was identified in 70% of idiopathic generalized epilepsy patients, suggesting a mechanism similar to television-induced seizures.
  • Non-photic factors like fatigue, sleep deprivation, and cognitive processing were important precipitants, especially in non-photosensitive individuals.

  • Twenty-nine percent of patients experienced partial seizures, predominantly occipital, with occipital spikes noted on EEG.

    • Implications:

    • Video game-associated seizures are linked to various epileptic syndromes.
    • Understanding specific triggers, including photosensitivity and non-photic factors, is crucial for effective management.
    • Further research into the neurophysiological mechanisms underlying video game-induced seizures is warranted.
