ALS-please help!

My mother was diagnosed with ALS in March of 08. July of 06 she suffered from a subarachnoid hemorrhage and shortly after that was diagnosed with primary progressive aphasia. None of her doctors had ever seen a patient with ALS and a stroke, there aren't any cases linking the two. We have been searching for the root cause of her illness. We believe that maybe it's parasites that have lead to the ALS, but have not been able to find them.

The last couple months she has seriously declined. Her condition is very aggressive. She can no longer talk or walk, has a feeding tube, and her breathing is severely compromised. Her pulmonologist said she could not survive any kind of a cold. She is extremely weak. The zapper has been ordered and we are planning on trying it on her. My concern is that it could be too strong for her. Maybe in her compromised and weakened condition there could be negative side effects? Is there a possibility that she is too weak and using the zapper could be the wrong thing to do? I welcome any and all advice. I thank you in advance for any help!
