title: Reflex epilepsy induced by playing oriental card or board games.
abstract: OBJECTIVE
  There are currently few studies on clinical profiles of reflex epilepsy induced by thinking and spatial tasks. We studied the clinical characteristics of reflex epilepsy induced by playing oriental card and board games.
  
  
  METHODS
  This study included 17 patients who presented with seizures that occur predominantly while playing games. We collected clinical data via protocol-based interviews. EEGs and brain MRI were performed.
  
  
  RESULTS
  All of the subjects were men, and all of them were older than 30 years at the onset of seizure. Thirteen patients (76%) experienced their seizures while playing the oriental card game "Go-stop" and the remaining four patients (24%) experienced them while playing the oriental board game "Baduk". Generalized tonic-clonic seizures were frequently preceded by prodromal symptoms, but myoclonus was not evident. Most patients had no spontaneous seizures and generalized epileptiform discharges on EEGs, and infrequent seizures that were well controlled.
  
  
  CONCLUSIONS
  Our patients exhibited some features that differ from those described previously in the literature, suggesting that the clinical spectrum of reflex epilepsy induced by thinking and spatial tasks is wide.
