Types of seizures:

The type of seizure will depend on which part of the brain is affected and how widely and rapidly it spreads.

These include:

  • Epilepsy
  • Head injury
  • Hypoxia
  • Low blood sugar
  • Alchohol
  • Drugs
  • Brain injury
  • Head injury


The casualty may look like they have suddenly “switched off” and stare ahead blankly. They may have localised jerking or twitching of their lip, eyelids or limbs. Some people get an ‘aura’ that they are about to have a seizure. It can be a pre-cursor for a full tonic-clonic seizure.

Tonic Clonic:

This type of seizure goes in stages. In the tonic phase, muscles become rigid and the casualty will drop suddenly to the floor. In the clonic phase, violent jerking movements of the limbs may be present. In the post ictal stage, the patient will be drowsy, disorientated, combative and may have a headache and want to just sleep.


Call 999: It’s their first seizure, they have repeated seizures, it’s longer than 5 minutes, they are unconscious for more than 10 minutes or they injure themselves
