Seizure—Child

Definition

A seizure is a sudden change in behavior. It is caused by sudden, abnormal, and excessive electrical activity in the brain. A neonatal seizure occurs in newborn babies. Seizures may be severe or mild. They may cause physical changes like convulsions. It may affect only part of the body or the entire body. A short seizure itself does not cause serious health conditions. Prolonged seizures can lead to permanent damage. The damage is due to decreased oxygen and excessive brain cell activity.
