Your brain contains billions of nerve cells called neurons that communicate with each other by sending and receiving electrical impulses.

A seizure occurs when there is sudden abnormal electrical activity that temporarily interrupts normal brain function.

Large groups of neurons fire at the same time like an electrical storm inside the brain that usually lasts from 30 seconds to two minutes.

This extra activity can cause changes in behavior, sensation, movements, or awareness.

There are two main types of seizures. Focal, or partial seizures happen in just one part of the brain, while generalized seizures seem to occur all over the brain.

Symptoms usually vary depending on the type of seizure and can include temporary confusion, staring spells, convulsions, or loss of consciousness.

If you think you've had a seizure, talk to your doctor right away for more information.
