A seizure occurs when there is a sudden want to learn more about epilepsy in children. burst of intense abnormal electrical activity within the brain. This causes a temporary disruption to the way the brain normally works. Symptoms experienced during a seizure depend on the part of the brain that is affected. What causes epileptic seizures? Epilepsy may begin at any age and for many children the cause is unknown. This can be confusing and difficult for parents to understand. When a cause is identified, it is usually one of the following: previous severe head trauma, brain injury at birth or previous infection of the brain e.g. meningitis or encephalitis. In rare cases, it can be linked to problems with metabolism or genetic disorders, brain tumours, brain malformations, stroke and degenerative nervous system diseases.
