Purpose: To study the clinical characteristics of patients with game-induced seizures in the Chinese population., Method: We assessed 51 patients with various game-induced epileptic seizures. Based on whether they had spontaneous seizures, these 51 patients were classified as two groups. Twenty-seven patients who had both game-induced and spontaneous seizures were referred to as Group I, whereas twenty-four patients that had experienced seizures exclusively while playing specific games were assigned to Group II. All of the related clinical data of the patients was collected and evaluated., Results: The patients in Group I presented with adolescent-onset and related to photosensitive idiopathic generalized epilepsy (IGE), were responsive to valproic acid (VPA) or magnesium valproate (VPA-Mg) therapy, and presented a major seizure-precipitating factor in response to electronic games. While patients in Group II were adult onset and not associated with IGE, showed uncertain responses to VPA and a benign prognosis, and presented major seizure-precipitating factors in response to non-electronic games., Conclusion: There are obvious genetic differences between patients with game-induced epilepsy. It is necessary to differentiate between various types of game-induced seizures and select the corresponding treatment., (Copyright © 2016 British Epilepsy Association. Published by Elsevier Ltd.

EPM2A has been certified as a causative gene in patients with Lafora disease (LD), which is a rare autosomal recessive and severe form of progressive myoclonus epilepsy. LD classically starts in adolescence, characterized by various types of seizure with myoclonic seizure as the main type. Typically within 10 years, intractable seizure attack, rapidly progressing dementia, and a vegetative state were present. LD is particularly frequently found in Mediterranean countries. Here, we report a Chinese family with a novel compound heterozygous mutation in the EPM2A gene, characterized by recurrent vomiting, intractable epilepsy, and progressive cognitive decline.
