What is epilepsy?

Epilepsy is not just one condition, but a group of many different 'epilepsies' with one thing in common: a tendency to have seizures that start in the brain.

Anyone can develop epilepsy, at any time of life.

Epilepsy is usually only diagnosed after a person has had more than one seizure and not all seizures are due to epilepsy. 

There are over half a million people with epilepsy in the UK, so around 1 in 100 people.

Other conditions that can look like epilepsy include fainting, or very low blood sugar in some people being treated for diabetes. On this page, when we use the term 'seizure' we mean epileptic seizure.

Causes of epilepsy

Different epilepsies are due to many different underlying causes. The causes can be complex, and sometimes hard to identify. A person might start having seizures for a variety of reasons.

 

 

Just diagnosed

This leaflet was created with the help of people with epilepsy, and includes their views and experiences. It also includes information on topics people told us they would have found helpful when they were diagnosed with epilepsy. 

Associated conditions

Epilepsy auras

An 'aura' is the term that some people use to describe the warning they feel before they have a tonic clonic seizure. An epilepsy 'aura' is in fact a focal aware seizure.

Epileptic seizures

There are many different types of epileptic seizure. Any of us could potentially have a single epileptic seizure at some point in our lives. This is not the same as having epilepsy, which is a tendency to have seizures that start in the brain. 

Epilepsy helpline

Epilepsy Society's confidential helpline is available for anyone affected by epilepsy. We welcome calls from people with epilepsy, their families and friends, as well as professionals such as doctors, nurses, care workers, teachers and employers.
