Is this EEG Really normal?

[davidmc]

I had a 48 hourambulatory EEG test in November.
I still hadn't received the results this month, so asked the secretary of the neurologist what was happening. She called back and said he had given permission to tell me the results over the phone - I always thought that was illegal in the UK?!
Anyway, she said they were normal.

Today I recieved the results which say:

"The patient had a 48 hourambulatory EEG on the 15th November 2011.
The patient reported 14 partial seizures and ten auras.

There were no cortical correlates seen during these events. The patient has a background EEG of defuse low voltage bilateral activity. predominatly fronto temporal zones.

There was no diagnostic epileptiform activity seen."

What does all this mean? Why would it say the above if it was normal? This is confusing.

<There were no cortical correlates seen during these events.>

it sounds like there was no neuroelectro data picked up by the EEG that classifies as seizure activity based on where they were focusing and at what Hertz

if results are normal there may not be as strict of guidelines regarding what sort of data can be conveyed over the phone

Thanks. So they were dfinately normal then. Sorry, it's just I've been told results have been normal before for other tests that weren't at this hospital.
They weren't really focusing anywhere, the wires were all over my scalp and a couple on my forehead.

I think it has more to do with the Hertz/frequency they target than the brain area
more electrodes= more distinct signal, not necessarily the area of the brain

Not quit sure what it all means but they weren't looking for anything in a specific part of the brain anyway, we didn't know what could be causing the seizures or where.

I don't know
