Re: 6 year old's eyes roll back and loses balance
She could be having a type of petite mal seizure. I would definitely have her see a Dr, preferrably a neurologist. Relay any pertinent info like how often it occurs, how she seems afterward, does it occur right in the middle of a coversation, activity, and how long she seems to be affected by it during and after. Any tendency to drop something in her hand, any jerking or abnormal sounds. Does she seem aware of it or does she pick up right where she left off. Any history of head trauma or brain injury related to birth, early childhood? You may need to start with her pediatrician if you need a referral.
