Seizures

What is a Seizure?

A seizure is an excessive surge of electrical activity in the brain thatusually lasts from a few seconds up to a few minutes. Seizures can cause a wide range of symptoms or effects, depending on which parts of the brain are involved in the abnormal electrical activity. A sudden andinvoluntary jerk of a hand, arm or whole body can be a seizure, as can asmell of burnt rubber, a strange feeling in the belly, a ringing sound that keeps increasing in volume, staring into space, or convulsive movements.

Many people think that a seizure must be a tonic-clonic or “grand-mal” convulsion, but even very “minor” and subtle symptoms can be seizures if they are due to abnormal electrical activity in the brain.
