My 13 y/o daughter recently had an incident on a trip to Australia where she was unconscious with drooling and twitching for a very short time and was seriously altered for about 15 minutes afterward. She had an EEG, which we just learned was abnormal -- she has sharp waves. She is having an MRI this week, but we can't see a pediatric neurologist for several more weeks. The circumstances of the likely seizure is that she was jet lagged, got little sleep the night before, spent the day on a river in a small boat, and it was very sunny tho cool and very windy, had little to drink, and was menstruating. My general questions are: do sharp waves always indicate a seizure disorder; can other stresses on the body (dehydration, menstruation, etc.) make one more vulnerable to a seizure; does a seizure of this short duration (2 minutes or less) cause damage to the brain; is it uncommon for a child of her age to develop a seizure disorder and are there specific types of seizure disorders that pop up at her age? I am very worried and a bit short on answers right now. Thanks for any general info you can provide.
