Hi, I saw someone from GreyTalk had visited and then saw this post. I'm so sorry Avril is going through this. I'm Zephyr's mom, http://hikinghounds.blogspot.com , Caron. Zephyr had a lot of similar symptoms to Avril, circling, ataxia, very anxious, I could tell his head was hurting. I got him to a neurologist and had an MRI done which showed encephalitis of a non-infectious origin. He started having seizures the next morning at the neurologists and they lasted 24 hours. They gave him all the drugs too, but the seizures kept coming. It was from the inflammation and swelling in his brain. He could not stand for three days after and it took over a week, for him to recover from the inflammation, swelling, and seizures and walk normal again, actually I didn't say 100% for 2 -3 weeks,. So, the things you are seeing in Avril could definitely go away as she improves. Since Zephyr's encephalitis was non-infections, I had every possible test run for ticks, fungus, etc., it's thought to be a bad auto-immune response. The treatment for this is steroids and in cases chemotherapy. Since he was seizing so bad and nothing at all indicated infection we gave chemotherapy about 12 hours after the seizures started. The chemotherapy treatment is only given when the cause is not infectious because it lowers the bodies ability to fight infection. I saw that Avril has the elevated white blood cells that could be from infection, so the chemo might not be for her. It has worked wonderfully for Zephyr. The MRI was crucial to his diagnoses. They weren't able to do the spinal fluid (CFS) when he first came in because the inflammation and swelling was too bad, but if you can do that it gives more and even better info. Zephyr just had his follow up work and he is really close to normal now, but we're doing another dose of chemo, etc. to be safe. He was on phenobarbital when he came home, then off for about a month, and then has had to start some again because he's had a few seizures that could be from scar tissue or maybe the small amount of possible remaining inflammation. This all started in March, it's been 4 months now. I couldn't read all your posts but if you haven't been to a neurologist I would really get her in to one. I know Zephyr wouldn't be here had I not been able to get him to the neurologist. I wish you and Avril all the best. It really sounds like she is a special girl having been through so much with you.
