I agree with ItrHate to be so blunt, but only you and those around you can answer that question.
Remember, surgery ISN'T 100% able to stop seizures, though the odds are good, hence why I decided to go ahead with mine.
I had this done, too. But I didn't really consider the electrodes being placed on my brain as "brain surgery".I've had 2 brain surgeries myself the first one was a video e.e.g. where they put the electrodes directly on my brain and my surgeon told me that was more dangerous than the ultrasound surgery I had done to reduce my seizures.
