SEIZURES

Types of seizure include: Generalized seizures, which involves the entire body and loss of consciousness. These types of seizures are more common in frontal AVMs. Focal seizures, “unusual feelings” or involuntary muscle movement, depending on the location of the AVM in the brain. People generally don’t have a loss of consciousness. These types of seizures are more common with parietal AVMs.
A seizure happens when a brief, strong surge of electrical activity affects part or all of the brain. It is thought that the scar tissue usually found in and around the abnormal vessels of an AVM disrupt the normal electrical activity of the brain causing seizures.

What to do if someone is having a seizure:

1. Stay calm.
2. Look around – is the person in a dangerous place?  If not, don’t move them. Move objects like furniture away from them.
3. Note the time the seizure starts.
4. Stay with them. If they don’t collapse but seem blank or confused, gently guide them away from any danger. Speak quietly and calmly.
5. Cushion their head with something soft if they have collapsed to the ground.
6. Don’t hold them down.
7. Don’t put anything in their mouth.
8. Check the time again. If a convulsive (shaking) seizure doesn’t stop after 5 minutes, call for an ambulance (dial 999).
9. After the seizure has stopped, put them into the recovery position and check that their breathing is returning to normal.  Gently check their mouth to see that nothing is blocking their airway such as food or false teeth. If their breathing sounds difficult after the seizure has stopped, call for an ambulance.
10. Stay with them until they are fully recovered.
If they are injured, or they have another seizure without recovering fully from the first seizure, call for an ambulance.
