Hearing a diagnosis of Alzheimer's

I haven't been keeping up this blog as regularly as I had been since the neurologist said to my husband, "You definitely have dementia, and it's probably Alzheimer's."

Getting such news is always a shock, certainly to the patient.  But I was shocked as well, even though I had seen more and more evidence over the past few years to confirm this diagnosis.  I was pretty sure Adrian had dementia, but the word "Alzheimer's" was much scarier. 

Neither of us has done well emotionally with this news.  Adrian denies he has Alzheimer's, and I feel isolated and lonely, as if I am dealing with the problem by myself. 

What is the best way to cope with this?  Do I pretend he's fine?  Do I write up an argument of proof and show it to him whenever he denies the truth?  I wonder if other couples have had this issue and how they've handled it?

I promise to update more regularly, and to fill in the missing pieces.
