My daughter had her first episode with PANDAS in 2010. We were lucky and had IVIG. However, the insurance company stopped paying, and we stopped the treatment. Fast-forward to this year. We have a new insurance company and they are paying for the IVIG. We have had 7 treatments. Usually she would have a reaction that would include near-rage to just irritability. This time...NOTHING. From what I understand this is an awesome sign. We had been seeing improvements in her the past 2 moths. The thing I think made all the difference is that her Lyme is being treated and the treatment seems to be working for that. With the Lyme under control I think the PANDAS is on its way out. This has been a long road, and I don't know if we are at the end of it or not, but it looks like we are at least seeing the light at the end of the tunnel!! Never give up. You never know what is around the next corner.
