Regarding neurofeedback, a good book to read is "A Symphony in the Brain" by Robbins. It's a good place to start.
As a long time meditator, I'm a firm believer in that whole "mind over matter" business, but I then I only tried it once I lost too much weight on Topamax. As a chemist and someone who worked for a small pharma out of college, I'm not opposed to drugs per se, they do save lives but aren't always necessary and definitely over-used here on this side of the pond. Essentially, I went on Topamax reluctantly so I would be allowed to drive again, and then went off of it when my weight got down to 105, skeptical that it was hurting me more than helping. My neurologist was very helpful and supportive of any alternative therapies I wanted to try, and he helped me taper off slowly once I started my neurofeedback sessions. I spent many months going to weekly sessions and lots of cash too. It was worth it because it helped me. I'm not sure everyone is a candidate. I don't believe in any one particular miracle cure (for any particular disease, for that matter).
The mom with the daughter also tried it after the high-fat, ketogenic diet did not work. I helped her pay for it because I was certain it would work. It didn't. they are back to her taking Phenobarbital but at least her seizures are under control.
