Majong Epilepsy

Hong Kong scientists review 23 cases of "mah-jong-induced seizures" in the August, 2007 issue of the Hong Kong Medical Journal.  Although there is similarity with other types of seizures, they claim mah-jong-induced seizure is a unique syndrome based on the late age of onset (average age 54), patient histories, electrophysiological studies (studies of a patient's brain electrical activity), CT scans, and MRI scans of the brain.  In the end, this study is very small and of those patients (3 out of 10) that did show some abnormalities in their brain wave studies, some had spontaneous seizures that occurred even without the stimuli of mah-jong.  Original article HERE.  Also on BBC.
