Before I started Nerofeedback I would have one or two episodes per month followed by 45 minutes of phycosis. ! tryed all the medications over a 25 year period,even surgery. After six months of treatments twice per week. Thats about 400 treatments at one hundred per treatment. All seizures stoped! no parcipitation is requried. the only side effects I noticed were more energy,more clairity less depression and a sence of well being.
