A seizure is a sudden burst of abnormal electrical activity in the brain. Normally, brain cells communicate in an orderly way using electrical signals — but during a seizure, that process goes haywire and brain cells fire uncontrollably. This runaway activity can cause a wide range of symptoms, including:

- Uncontrolled shaking or jerking
- Stiffening of the body
- Loss of consciousness or awareness
- Unusual sensations (taste, smell, vision, touch)
- Changes in mood or emotions
- Temporary "freezing" or stopping of movement

Seizures can last anywhere from a few seconds to a couple of minutes on average. Most seizures are not emergencies, but one lasting longer than 5 minutes is considered a medical emergency called status epilepticus.
