Epilepsy is a brain disorder in which people experience ‘seizures’ – sudden surges of electrical activity in the brain.5 During a seizure, people can experience changes in awareness and how they sense things, from ‘spacing out’ to completely losing consciousness. Physical symptoms can also be experienced, including feelings of stiffness, tremors, and convulsions.5 Depending on the type, a seizure can last from a few seconds to several minutes.6
There are many known causes of seizure, such as a stroke and head injuries, though in most cases no cause can be identified.7 Lennox–Gastaut syndrome is a rare but severe type of epilepsy that emerges during infancy or early childhood.8 Typically, the seizures cause the sufferer to either stiffen or go limp.8 Dravet syndrome is a rare type of childhood epilepsy that typically starts within the first year of life. Seizures are most often associated with a high temperature and usually involve only one side of the body, although both sides of the body may also be involved.9
Epilepsy is usually a lifelong condition that can affect a person’s safety as well as their ability to function at work or school. However, most people can live normal lives providing their seizures are well controlled.5
