Please keep Riley in your thoughts

Last night he had 3 or 4 mini seizures (remained upright but was drooling and twitching), I took him to the vets first thing, he had a blood test and then came home. About an hour later he had a full on seizure, thrashing and writhing around and was totally out of it.
When the blood test results came back they rang and asked me to take him in to the hospital, he was there two hours and they rang again saying that he needed to be taken to a specialists and is there awaiting an MRI.
I'm so worried about him can't stop crying
