Quick Question about seizures, very important...

My father has had two incidents in the past year and a half which have had us baffled. He basically passes out, after a dizzy-spell or a bout of vertigo, then collapses and seizures. Both incidents occurred in grocery type stores under fluorescent lighting. This last one, was luckily caught on video. Since none of the family was with him at the time, my mother and sister got to see what happened. They describe seeing him jerk his head to one side, while walking, and then begin to do a series of spins (still while walking). He then fell, and proceeded to have a grand-mal seizure. My question is has anyone had similar pre-seizure experiences where you continue to walk/stagger, or spin around while walking? We were thinking it was vertigo and first but something doesn't seem right about spinning around, most people would stop and steady themselves. And he's no help, he doesn't remember anything but waking up in the hospital. Okay, i know i said the question would be quick! Guess I lied :) Anyway, any input/ideas would be appreciated, as they are still doing tests today and my concern and curiosity are growing. Thanks, Kerin

Thanks for all the info. We still have no idea what's going on with him. The doctor is never around so all the tests he's had (the EEG, bloodwork,heart monitor, and MRI to name a few) we haven't the foggiest notion what the results are. He's on Dilantin right now. We are not convinced that this was simply a seizure, but it's so hard to know for sure. When this happened a year and a half ago (the first incident), he was diagnosed with BPPV (Benign Paroxysmal Positional Vertigo) but this time the doc just thinks it was a seizure. My mom says the seizure happened AFTER he fell and hit his head, but I just wanted to know if this type of activity could be part of a seizure somehow. Thanks! Kerin
