For the brain surgery, It's not so much the type of seizures. It's where in the brain they are located and whether or not , it's worth doing.

Surgeries like the VNS is for anyone willing to try and reduce the seizures ( for some people it helps and others not so well ) .

VNS stands for Vagus Nerve Stimulator.

what does vns stand for?

I had brain surgery. I had a spot removed from mine though from a car accident. I had a closed head condition.
