Epilepsy is a brain condition.
It can make a person have seizures (sometimes called ‘fits’ or ‘attacks’).
A seizure is a sudden burst of electrical activity in the brain.
A seizure can make things happen to your brain and body – these things can be different for different people.
Some seizures make your body jerk and shake.
Some seizures make you feel a bit strange or make you unsure where you are.
Epilepsy can start at any age and usually lasts for the rest of your life.
