J.R.
I'm only slightly familiar with the test you are talking about but they seem to be pretty informative. I just wanted to lend some hugs and support from a fellow special needs Mom. My 3 year old daughter has Angelman Syndrome and although she doesn't have seizures now, she did have quite a few one day when she was 5 weeks old. She went on seizure meds for 2 1/2 months and (knock on wood) has never had another one that we know of. She has done the staring thing but we can usually interrupt it but I always wonder if we are interrupting or if she's just done. We'll be getting one of the sleep EEG's sometime in the next year or so just to make sure because they can be hard to identify.
I also wanted to add, since you said your daughter may have Autism, that they came out a couple of months ago and said that a good indicator of Autism is if they respond to the name at age 12 months. They said that something like 75% of kids that didn't respond to their name at 12 months ended up having Autism or some other delay. Here's a link to the story: http://www.msnbc.msn.com/id/17920545/
Best Wishes to you and your daughter,
J.
