Hi tos8,
Your sz. sound very similar to mine. I'm no neuro but what you are describing sounds a lot like my clonic sz. when you're in and out of it and can't do a thing what concerns me is when they last over 10 min. this is known as a status sz. and can cause more brain damage. I started to have absence status sz. a few yrs. ago when I was put on the drug neurontin for headaches from a concussion I got when I was in an auto accident. After I went off the neurontin the status sz. stopped completely. What I find interesting is how your mom can bring you out of these sz. with her voice, this may happen do to the sound of her voice. Some people with epilepsy have audio and visual sz. and that's when certain sound or lights can trigger sz. but in your case it's stopping the sz. be sure to mention this to your neuro and I would also look into taking keppra to see if it helps you.

I wish you only the best and May God Bless You!

Sue
