|A seizure is a condition that occurs when the electrical system of the brain malfunctions. When the brain functions normally, a multitude of tiny electrical signals are produced by the nerve cells of the brain and other parts of the body. With a seizure there is a short, temporary disturbance within the electrical system of the brain – like when a power outage occurs and the electricity switches off.
Seizures cause uncontrollable changes in body movements, behavior, awareness or sensation. Before a seizure occurs, there may be warning signs known as an aura – unusual smells, tastes or sensations.
After a seizure has occurred, the person will often experience after effects such as a headache, confusion, fatigue, sore muscles and unusual sensations - this is called the postictal state. When seizures recur, the condition is known as epilepsy.
