Epilepsy is a group of chronic neurological disorder of the brain that affects around 1-2% of the population across the world. According to the World Health Organization (WHO), epilepsy is characterized by periodically spontaneous seizures, which are usually due to excessive electrical discharges in a group of brain cells. The earlier day electroencephalogram (EEG) signals are useful tool for detection of epileptic seizures.Epileptogenesis is a slow process. After several months of initial insult, spontaneous recurrent seizures begin to appear. Epilepsy is considered to be resolved for individuals who are seizure-free for the last 10 years, with no seizure medicines for the last 5 years. Currently, used drugs available for treating epilepsy have draw backs like Epileptogenesis and other dose-related side effects. In spite of daily treatment, nearly 30% of patients continue to have convulsions and fail to provide a complete cure. Hence, there is a need for another alternative option to control the epileptic seizure and minimize the duration of seizure without taking a medicine and improving the quality of patient’s life. In current scenario the Vagus nerve stimulation (VNS) has become an important tool for controlling the epileptic seizure. Vagus nerve stimulation is used for patient with refractory and drug resistant epilepsy. Various non-drug therapies form preclinical to clinical for controlling seizures in epileptic patients with drug resistance current available have been highlighted in this review.
