Normal brain function is made possible by millions of tiny electrical charges passing across nerve cells in the brain and to all parts of the body. In a seizure, this normal pattern may be interrupted by intermittent bursts of electrical energy that are much more intense than usual. These 'storms' affect the delicate systems responsible for the brain's electrical energy, and may affect a person's consciousness, awareness, movement and bodily posture for a short time. Normal brain function cannot return until the electrical bursts subside. Epilepsy is the tendency to have repeated seizures.
Seizures can be frightening to witness but they are not usually a medical emergency. In most cases once the seizure stops, their breathing returns to normal and the person should make a swift recovery.
This information is particularly relevant for tonic clonic seizures where the person shakes or jerks.
If in doubt always contact the emergency services for help and guidance
