"Death sentence" Well in Christine's case (at 46yrs) compared to e.g. an 80 year old person just recently diagnosed with dementia/alzheimer's I assume it is more often a slow progression, where as in the case of an ~80yr old it is most commonly closer to the time frame she mentions of 8 years or as I have found the research suggests ~4 years. I can only guess that her being told 8 years was very likely yet worse case scenario and she was being told that so she could be prepared for that to be a likely outcome rather than living in false hope of an unreasonable expectation of the years she has ended up having.
