What about the final stages of CJD disease?

As you are at the end stage, you are aware that few live longer than a year with this disease.
I would suggest hospice and medication, but having dealt with this disasterous disease you will have medical personnel involved, and that is who you should be discussing this with.

I am so sorry.
