I have seizures that cannot be seen from a surface EEG. They were sure I had epilepsy when I was diagnosed with it but they couldn’t prove it. I was referred where they surgically implanted depth electrodes into my brain. They drilled holes in my skill and implanted electrodes into the brain. Then they found the seizure focus. The seizures come from deep within the brain. I’ve never known or heard of anyone having this. Has anyone else ever had this done?
