I've had an EEG. They were checking for seizures. Came back negative for seizures, but they noted in it that I had increased theta activity.
I was already diagnosed, and they didn't tell me anything about whether this was associated with autism.
I didn't know what theta activity was, so I looked it up and found this:
Quote:
The theta rhythm is an oscillatory pattern in EEG signals recorded either from inside the brain or from electrodes glued to the scalp. Two types of theta rhythm have been described. The "hippocampal theta rhythm" is a strong oscillation that can be observed in the hippocampus and other brain structures in numerous species of mammals including rodents, rabbits, dogs, cats, bats, and marsupials. "Cortical theta rhythms" are low-frequency components of scalp EEG, usually recorded from humans.
As it says oscillatory pattern, I'm unclear whether this is the same thing as the sharp wave activity I had or whether it simply means that it goes up and down, but not necessarily sharply. I mean don't all brain waves go up and down anyway?
Interesting.
