I to have NES's. Mine were debilitating, and I eventually was treated with ECT (Electro-convulsive Therapy) It help TREMENDOUSLY. I went from several "grand-ma like" seizures lasting 12 or more hours a week, to one in about 9 months. Its not a common treatment though, and I did suffer memory loss. If they are true NES, anti-convulsants DO NOT HELP. Sometiems though, Valuim does limit the longevity and severness.
Do not let doctors tell you she is faking though. Sometimes as soon as they hear or even think the word "pseudo" they think "fake".
I also could hear during part of my seizure. It is a very frustrating experience. I suggest crarring sometime in her purse that explains her seizures are Non Epileptic so they don't load her with meds that dont help. One time i had a seizure in the mall by myself and nobody new what to do, and once in an ambulance they drilled a hole in my leg bone and put an IV in called an IO so they could rush the anti-convulants in and they did no good.
if you see a Psychologist or Psyciatrist, make sure you get one that has experience with NES. If you live close to TN there is a Dr. Rice and Dr. Varma that work with St. Francis Hospital in Memphis TN. ( I like Dr. Varma better).
I really hope these things go away completely for your daughter. I know that they are hell to live with.
Best to you and feel free to ask any questions.
