What Is a Seizure?

A seizure is a sudden surge of abnormal electrical activity in the brain. Electrical activity in the brain is normal. It’s how our brain works. Seizures occur when there is significant disruption of that normal electrical activity in the brain. The general symptoms of seizures may include changes in consciousness, sensation, movement, or behavior.

Is a Seizure the Same Thing as Epilepsy?

Not all seizures are caused by epilepsy.

No. Not all seizures are caused by epilepsy. Approximately 10 percent of the general population may experience a seizure during their lifetime, but only 1 percent of the population has epilepsy. A single seizure may or may not progress to a chronic and recurrent condition or epilepsy.
