What is epilepsy
Epilepsy is a disorder of the brain in which there is a tendency to have recurring seizures. The fact that seizures can reoccur is key, as a one off seizure does not mean it is epilepsy.
There are over 40 different types of epilepsy, and it can affect anyone, at any age, from any walk of life.
An epileptic seizure results from a sudden electrical discharge in the brain that causes changes in sensation, behaviour or consciousness.
Seizures can take many forms because the brain is responsible for such a wide range of functions. Seizure symptoms depend on where in the brain this abnormal burst of electrical activity happens. As a result, there are many different types of seizures - most usually last from a few seconds to a few minutes and usually stop without any treatment.
Epilepsy facts and stats

- In the UK 1,150 people died of epilepsy related causes in 2009. In England and Wales 10% or 11% of those deaths are young adults or children under the age of 25.
