Summary

Mah-jong epilepsy is a newly identified reflex epilepsy triggered by playing mah-jong. Seizure control is often good with anticonvulsants and avoiding mah-jong.

Area of Science:

  • Neurology
  • Epileptology

Background:

  • Reflex epilepsy can be triggered by various stimuli, including visual, cognitive, and sensory inputs.
  • A subset of patients experienced seizures exclusively while playing mah-jong, a complex cognitive activity.

Purpose of the Study:

  • To investigate the characteristics of a newly identified reflex epilepsy induced by playing mah-jong.
  • To explore the potential mechanisms and clinical features of mah-jong-induced seizures.

Main Methods:

  • Retrospective review of 12 patients with mah-jong-induced seizures from 1987-1999.
  • Evaluations included electroencephalography (EEG), neuroimaging, and clinical seizure analysis.

Main Results:

  • Most patients experienced generalized tonic-clonic seizures; some had partial seizures.
  • EEG and neuroimaging results varied, with some showing abnormalities and others normal.
  • Nine out of 12 patients achieved good seizure control with anticonvulsant therapy.

Conclusions:

  • Mah-jong epilepsy is a distinct reflex epilepsy likely linked to cognitive processes during gameplay.
  • The condition appears to have a benign prognosis with effective seizure management.
  • Avoiding mah-jong is crucial for seizure prevention in affected individuals.
