There are no solid treatment guidelines for idiopathic intractable epilepsy in children. The investigators propose that vitamin C being an antioxidant will improve seizure frequency and EEG in children with idiopathic intractable epilepsy.

Is vitamin C; being an antioxidant based on the hypothesis of oxidative stress as a provocation factor for idiopathic epilepsy low in those with idiopathic epilepsy, and is it lower in those with refractory than those with newly diagnosed? Will vitamin C supplementation for 1 month be efficient to raise the vitamin C level and will it improve seizures and EEG findings in those with idiopathic epilepsy?
