Sometimes what ppl experience is 'unique' unto them. I do know that Neurological Issues such as Doose Syndrome/Epilepsy Can cause Behavioral Issues. But, so can the medications we are on to treat the disorder. Wikipedia can describe what to expect as far as seizure activity, but does not include behavioral issues.

Several Types of Seizure symptoms can be noted. Resources: Epilepsy Faqs has descriptions of the various Types of Seizures.
For Even More Info, Visit the Epilepsy Foundation. Site is listed in our Resources. Search for Doose Syndrome. Plus, (Search Again) there should be a Foundation in your State & possibly an affiliate near you & ask them for material that would help you. They can, also, send a rep to your school to educate you, the nurse & the Whole school. A Lot of Schools are doing this now. Education about Doose Syndrome (which is just 1 of many Types of Epilepsy) & all it's aspects Needs to be Shared w/ Everyone. Adults & Kids! Unfortunately, Epilepsy is a health Issue that a Lot of PPL know nothing about. Everywhere. Yet over 65 Million ppl, worldwide, are affected And it is the Oldest Disorder Known to Mankind. You can Help by getting this Info 'shared' w/ your school. Definitely 'Speak Up'!
KUDOS to you for Wanting to Know more. I truly understand the dilemma you are experiencing. By Learning More, you will be able to help the child, the parents & possibly other children/parents.

BTW: There are Diets that Mite assist the child, too. The Atkins Diet was noted on FaceBook.

Ask her parents How Much they Know!
As a Teacher, I consider you a 'caretaker'. Why? Becuz, you spend More time w/ the child then the parents do. Maybe there is Something they are Missing. Yes, she isn't/shouldn't be held accountable/ responsible for 'seizure activity'. But, she should have Help w/ any Behavioral Issues!
One of our Mottos (And I'm sure it's yours, too) Education IS Power!

P.S. You deserve Support, too. So feel free to Vent anytime.
