A seizure disorder, also known as epilepsy, is a neurological condition that causes recurring seizures. A seizure is a sudden, uncontrolled burst of electrical activity in the brain that can cause changes in behavior, movements, feelings, and levels of consciousness. Seizures can vary in type, symptoms, and severity, and they can last from 30 seconds to two minutes. Having two or more seizures at least 24 hours apart that dont have a known cause is considered to be epilepsy. Seizure types vary by where they begin in the brain and how far they spread. There are two main categories of seizures: focal, meaning they start in a particular part of the brain, and generalized, meaning the seizures initially involve all areas of the brain. Seizures can be caused by various factors, including genetic changes, brain injuries, infections, and severe illnesses. Treatment for seizures often involves medication, and in some cases, nerve stimulation or surgery.
