Generalised seizures are caused by epileptic activity in both halves of the brain.

Consciousness is lost during the seizure, although sometimes this is very brief.

In some types of generalised seizures the epileptic activity misses a small part of the brain. This means that the presentation of generalised seizures will vary depending on how much of your brain is affected.

The main types of generalised seizure are: tonic-clonic, absences, myoclonic, tonic and atonic.
