In brief: Toxic effect
A seizure is a reaction of the brain to a toxic condition.
If the region of the brain that controls nausea and vomiting are involved, then the seizure will cause vomiting. In addition, some patients develop migraine symptoms following a seizure. The vomiting can lead to aspiration pneumonia, that is why they should be laid on their side and nothing put in the mouth.
