What is a seizure and what is epilepsy?
Average rating:
A seizure is a short episode of symptoms caused by a burst of abnormal electrical activity in the brain. Typically, a seizure lasts from a few seconds to a few minutes. (Older words for seizures include convulsions and fits.)
The brain contains millions of nerve cells (neurones). Normally, the nerve cells are constantly sending tiny electrical messages down nerves to all parts of the body. Different parts of the brain control different parts and functions of the body. Therefore, the symptoms that occur during a seizure depend on where the burst of electrical activity occurs in the brain. There are different types of seizures but they are broadly divided into two main types - generalised and partial.
- Generalised seizures. These occur if you have a burst of abnormal electrical activity which spreads throughout the brain. It affects consciousness, and may cause a convulsion.
- Partial seizures. In these type of seizures the burst of electrical activity starts in, and stays in, one part of the brain. Therefore, you tend to have localised or 'focal' symptoms. Different parts of the brain control different functions, so symptoms depend on which part of the brain is affected. Partial seizures may not affect consciousness, but may affect sensations, emotions, behaviours, muscles, or combinations of these.
