Good news, Elijah does not show any seizure activity. Andy was the one who talked to our neurologist and he thought the doctor actually seemed a bit surprised on how "normal" parts of the EEG looked.
The only strange thing he mentioned was that Elijah has "extra electrical activity" on the back right side of his brain when he is sleepy and asleep. It's not seizures and there isn't anything we should do about it, but it's something they see when a person is more susceptible to seizures. With Elijah's seizures shortly after birth and the massive injury to his brain, he'll probably always be at a high risk for developing seizures. We just need to do what we've always done - watch Elijah closely. The neurologist didn't seem concerned about it, but thought it was worth mentioning.
The test did reassure us that Elijah isn't having any seizures, though. Our doc mentioned that the brain waves of kids who have infantile spasms look different than Elijah's brain waves. He reassured us that what we saw in March was most likely not seizure activity. Phew.
All in all, I think the test put our minds at ease a bit and we can go back to watching Elijah like hawks and um, relaxing (wait, what's that?)...
