Thanks all, reading all this is very helpful.

About PANDAS-- I think one of the strange things is that everyone's experience is different, so it's hard to create a support group or anything. I had not heard about seizures being related to this before-- mostly OCD and tics and behavior problems. I'm not totally convinced PANDAS is what's happening with my son, but I AM absolutely sure that a certain antibiotic (Omnicef, a global antibiotic) changed his behavior, dramatically, for the better. They have changed him to a weaker, prophylactic dose of amoxicillin (just a few days ago) and I think the strange behavior is coming back... so I am confused and trying not to get desperate...

I am starting to believe that lots of psychiatric conditions may in fact be autoimmune problems-- related to infections.

thanks again--
