My wife has tried EEG neurofeedback a few times now. The first time she tried it, they used an SMR entraintment protocol. It took about 5-6 months before we saw results, but when they kicked in, she enjoyed the next 4 years seizure free and med free. She sipped from the Holy Grail.
Unfortunately, her hormone system went Helter Skelter after delivering our first child and she started having a lot of seizure activity again. Things got progressively worse for her with successive pregnancies.
We tried LENS neurofeedback and briefly, QEEG guided neurofeedback at various points, but it was hard to determine if she realized any therapeutic results from them. There was a lot going on at the time.
I would love to give EEG neurofeedback another try now that she is somewhat stabilized with her seizure control (on meds). It's just not feasible for us right now.
She never tried acupuncture, but she did experiment with acupressure years ago. I don't think it offered her any therapeutic benefit with respect to seizure control.
YMMV.
