However, a seizure can be the prominent feature in inherited metabolic disease. The specific diagnosis of an underlying inherited metabolic disorder in epileptic patients may help design specific treatments that can improve the seizures and stop neurodegeneration. In several inherited metabolic diseases such as vitamin-responsive epilepsies and other metabolic epilepsies, seizures are refractory to antiseizure medications but respond to specific treatments based on vitamin and cofactor supplementation or diet. This review discusses our current understanding of these inherited metabolic disorders associated with epilepsy, where early diagnosis and treatment initiation will significantly improve the outcome.
