I've already e-mailed the neurologist that helped me so much with my Portia that I lost to epilepsy in March and told him what happened, and that I work with for my Aiyana, who's also epileptic. I got an automated response saying he was out of the office until this coming Tuesday, so hopefully when he returns to his office he'll get back to me and let me know his thoughts, but I know him well enough to know the first thing he's going to suggest is a full cardiac workup in addition to the lab work we've already done. If that shows nothing, I'll see what he suggests, be it just watch him and see if it happens again, do an MRI, whatever, I don't care. Thankfully he's almost never alone - and now he's never alone, if for whatever reason I can't be with him myself I take him to a very close friends how, even if I'll only be gone an hour or two, I'm to scared to ever leave him alone after that
The horror of epilepsy with Portia forever made me paranoid, watching it worsen and progress with her was heart wrenching. It may have been a one time fluke, but I won't chance it!
I'll be sure to update once he sees the cardiologist with what if anything he finds.
