A seizure is the result of abnormal brain function. The nerve cells in the brain give out electrical charge. If too many nerve cells fire at once, it may cause a seizure.
There are two categories of seizures. Focal seizures, also called partial seizures, are the result of abnormal brain activity on one side of the brain. Generalised seizures are a result of abnormal brain activity on both sides of the brain.
A mild seizure may last a few seconds to a few minutes. A child may simply stare off into space and be unresponsive, or they might twitch. More serious seizures last for several minutes. The child may fall down, lose consciousness, have convulsions, and even lose control of the bladder and bowel.
