People with epilepsy have been stigmatized since the time of Hippocrates. Two epilepsy specialists, Dr. Caitlin Hoffman, a Weill Cornell Medicine pediatric neurosurgeon, and Dr. Heidi Bender, a neuropsychologist at Mt. Sinai Hospital, explain what happens in the brain to cause seizures. They give parents, teachers, kids, and their classmates a primer on understanding this common disorder and how we can best help if we see someone having a seizure.
