An epileptic seizure (colloquially a fit) can be described as a brief episode of signs and/or symptoms which are due to abnormal, excessive, or synchronous neuronal activity in the brain.  The outward effect can vary from uncontrolled jerking movement (tonic-clonic seizure) to as subtle as a momentary loss of awareness (absence seizure). The following list contains a more comprehensive set of symptoms:
- Losing consciousness and then exhibiting confusion afterwards.
- Having uncontrollable muscle spasms which often result in falling.
- Drooling or frothing at the mouth.
- Jaw clenching and tongue biting.
- Having sudden, rapid eye movements.
- Making unusual noises, such as grunting.
- Losing control of bladder or bowel function.
