When seizures happen, the flow of electrical signals in your brain is disrupted. What is a seizure? A seizure (pronounced “see-zhr”) is a surge of abnormal electrical activity in your brain. The most recognizable symptoms of a seizure are a temporary loss of consciousness and uncontrollable movements (convulsions).
Depending on the regions of the brain involved, seizures can lead to changes in movement, sensation, behavior, awareness, or consciousness. Symptoms vary widely.
Seizures are changes in your brain’s electrical activity. Learn more about types of seizures, causes and symptoms, and how you can help someone having a seizure.

Epilepsy (sometimes referred to as a seizure disorder) can have many different causes and seizure types. Epilepsy varies in severity and impact from person to person and can be accompanied by a range of co-existing conditions.
During a seizure, those signals become sudden and disorganized, interrupting normal brain function for a short time. Some people have a single seizure in their lifetime. Others have a medical condition, such as epilepsy, that makes them more likely to experience repeated seizures.
A seizure is a sudden change in the brain's normal electrical activity. During a seizure, brain cells "fire" uncontrollably at up to four times their normal rate, temporarily affecting the way a person behaves, moves, thinks, or feels.
