Hi my daughter does this too! She will be 11 next month, but she also has "Absence seizures, ADHD, bipolar mood disorder & ODD, learning disability,slight speech impairment." She see's specialist a DeVous in G.R. Maybe she needs to see/have some test's done. We didn't realize our daughter was having seizures until she was 4. There's so many different types of seizures, which we didn't know of. My husband has what they call Grand Mall these are the worse. Found out when our daughter was 5 that she had all this other stuff too. Alot of these specialist won't see you with out a referral from you family phys. If you do get her tested and they find nothing then it's a blessing. And maybe it's just a nervous tick. Any how good luck. Maybe see if someone has a camcorder you can barrow too.
The video will also help the specialist if you see them.
