What causes convulsions?

Convulsions/seizures are caused by abnormal electrical activity in the brain. For a bit of background, the brain is part of the central nervous system, which controls and 'instructs' the body on what to do. The brain sends these instructions out using electrical impulses and signals.

If the brain becomes confused, for whatever reason, the electrical impulses may begin to send abnormal impulses to the wrong places and via the incorrect neurons. This causes the body to get confused and results in abnormal twitching and convulsing.

People with a medical condition called epilepsy have an abnormal brain electrical activity giving rise to epileptic seizures.

Seizures/convulsions can also be caused by a brain tumour or another nervous system disorder. It is vital every seizure is reported to your medical practitioner.

If the seizure last for longer than normal, or if it is your first seizure, seek urgent medical assistance or phone for an emergency ambulance.
