What are Epileptic seizures?

A seizure happens when there is a sudden burst of intense electrical activity in the brain. This causes a temporary disruption to the way the brain normally works. 

The result is an epileptic seizure.

There are many different types of seizure. What happens to someone during a seizure depends on which part of their brain is affected. During some types of seizure, the person may remain alert and aware of what’s going on around them, and with other types they may lose awareness. They may have unusual sensations, feelings, or movements. Or they may go stiff, fall to the floor and jerk.
