Just interested in comparing results. Mine was in childhood, at the age of 12 following some epileptiform attacks.

The result was abnormal (they didn't find a brain LOL :lol: :lol: :lol: ). Seriously, I had some abnormal activity, stated as "paroxysmal sharp wave activity" (which may have been in the post-central brain area).

I have found some links about how EEGs relate to autism amongst other things:
http://medical.med.tokushima-u.ac.jp/jm ... _p175.html
http://asdresearchinitiative.wordpress. ... -epilepsy/
http://neuro.psychiatryonline.org/artic ... eID=103257

...and there was also the http://www.bbc.co.uk/news/health-18577327 article about the EEG brain trace and autism research which had 90% reliability in picking up the differences in autistic brain activity.

My results may or may not correlate, because I'm not 100% clear which part of the brain my trace was from and it may be that there are specific areas of the brain where the activity has been shown to correlate, that differ from mine. Having said that, the science is far from exact in this area yet.

What I'm interested in, is if anyone else has had an EEG and do you know your results? If so, what were they? Did your Dr tell you anything about your results that indicated autism? Did you have an EEG and get diagnosed later on, or were you already diagnosed and the EEG confirmed your clinical status?

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.

Yes. I have absence seizures of the frontal lobe. I have not yet been diagnosed with autism; the test results are still pending.

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.

Same. Unlike you, it was pre-diagnosis.

I suspect I had a stroke at 12 i had an EEG my mother never shared the results. I was supposed to get one a few years back when i started having seizure-like episodes (weird ones because sometimes I was awake while my body was being stupid) but I never did.

I had two a couple of years ago, nothing out of the ordinary.
