Before the brain surgery they did many pre test. I went thru the Neuro Psych Test, 4 hr EEG, MRI, and the WADDA Test as Courtney explain above, th week of my brain surgery, they prepped me for The GRID Test/ EEG. The Grid is a a flat plastic panel with electrodes in it. They open the skull, where the seizures are active and place the Grid on that part of the brain. The grid will work with the EEG and map where your seizures are located. Once they have that mapped out, they will do your surgery next.

Hi there I had temporal lobe resection surgery two years ago!! What they do is take a piece of tissue that is causing the seizures!! It's usually no bigger than the size of your thumb!! Before the surgery they might do a WADDA test!! Paralyzing each side of your brain to make sure that they have the right side that they're going to operate on!! Please ask your doctor about a WADDA test you can google it I did and it's not as scary as it seems!!
My recovery time was six weeks I was in the hospital for four days!!! I've been seizure free for two years I think better I don't get is mad!! I came out of that surgery literally a whole new person!!

Gutted to read this I suffer temporal lobe but it's too deep in the brain to be operated 😥 so had to settle for VNS x
