Seizures

The cells in the brain, known as neurons, conduct electrical signals and communicate with each other in the brain using chemical messengers. During a seizure, there are abnormal bursts of neurons firing off electrical impulses, which can cause the brain and body to behave strangely.

The severity of seizures can differ from person to person. Some people simply experience an odd feeling with no loss of awareness, or may have a “trance-like” state for a few seconds or minutes, while others lose consciousness and have convulsions (uncontrollable shaking of the body).

Some people may only have a single seizure at some point during their life. If they do not have a high risk of having further seizures, they would not be regarded as having epilepsy.
