Has your daughter had any heart tests to see if the seizures are heart related? I simple ECG will show up usually if this is the case.Have you heard of LONG QT SYNDROME? Maybe this could what is causing the seizures with your daughter if all EEGS have come back clear, my daugter was diagnosed as having some kind of seizure disorder even though EEGS were clear because they couldn't think of any other reason why a fit and healthy young girl would faint/seizure. Please visit our website about this condition to find more information. www.sads.org.au All the best with finding the cause of whatever it is with your daughter. Does anyone else in the family ahve similar things happen, like fainting? Long QT Syndrome is genetic so if this is the cause, then the whole family will need to be checked also, with treatmenst the outlook is very good for a pretty normal lifespan.
