Seizures are a frequent cause of morbidity in the pediatric age group. Uncontrolled seizures pose a variety of risks to children, including higher rates of mortality, developmental delay and/or regression, and cognitive impairment. The ketogenic diet is a well known treatment option for refractory epilepsy. However it is very restrictive and requires strict weighing of foods. The modified Atkins diet is a dietary therapy for intractable childhood epilepsy that was designed to be a less restrictive alternative to the traditional ketogenic diet. Early studies have demonstrated efficacy and safety.There are no randomized trials evaluating the efficacy of the modified Atkins diet in children with refractory epilepsy. Hence this study has been planned to investigate whether there are clear benefits in terms of seizure control in children with refractory epilepsy who are treated with the modified Atkins diet, versus controls.
