I had these as a kid----even, up into my twenties (and, while driving)----but, I was never told it was related to my Autism, because I wasn't diagnosed an Aspie, until I was 47 (or 48).
To me, they're like..... Say you were working on a special interest, and had to stop and answer the door, and when you got back to your project, you might say: "Now, where was I?"----that's the way I've always experienced them; when, I "get back", I'm like "Now, where was I", and it's always been more than "zoning-out", to me; cuz, zoning-out seems almost to be a choice (like, when you choose to tune-out someone who is droning on-and-on, about something), and lasts alot longer.
I have had "regular" seizures", as well, my entire life (and they run in my family)----but, with regular seizures I am aware of everything that's going-on around me, but can't "participate". I have described it to a few people, as it being like I'm out in a large field, somewhere, and everybody is on the road, and I can see them, and know what they're doing, but I can't call to them, to help me.
My neurologist confirmed that I have seizures, but I haven't been diagnosed with Epilepsy----it seems to me that one has to have so many, in a certain timeframe, or something.
