Causes of Seizures Epilepsy A seizure disorder in which reoccurring seizures are the main symptom caused by an abnormal discharge of electrical activity from the neurons in the cerebral cortex. Treatments for Epilepsy 3 major courses of treatment: Drugs Generally first line of attack because it is effective, relatively inexpensive, and safe Diet Ketogenic diet - lots of fat and almost no carbohydrates This diet drastically alters the way our bodies get energy from food - instead of making glucose, it makes ketones Surgery Commissurotomy Commissurotomy For patients with frequent and violent epileptic seizures, surgically splitting the corpus callosum was the only relief - known as a “commissurotomy” Corpus callosum is a bundle of nerve fibers which serve to connect the right and left cerebral hemispheres Split - Brain P
