That's a pretty accurate description of what happens with my MIL. At least
my MIL doesn't seem to get too upset about things but often she is
incredulous at what we tell her. A couple nights ago she wanted the address
of her old boyfriend who died 8-9 years ago. She just couldn't believe he
was dead and had been dead for so long. She often thinks she is just
visiting.

I'm now dealing with dementia with both my MIL and my father. Both have some
AD along with some dementia from other causes. My father has spent 5 months
of the past year in a nursing home and will probably get out the end of Jan.
Then he will return to their tri-level house where I am betting he doesn't
last 6 weeks before falling again and breaking something.

My new rant is that my father bought long term care ins. 13 years ago and
recently when my mother turned in the first claim, the ins. company made one
payment then told her the original salesman had made an error and sold them
the wrong policy and no further payments would be forthcoming. I am
astounded that every person I've met who has bought long term care ins.
seemingly gets screwed by the ins. co. when they finally need the coverage
they purchased. My MIL's boyfriend who died at 89 paid for 38 years - 8
years past having a fully paid up policy and he was talked out of accepting
the care when he really needed it. After he got old and goofy the ins.
company started feeding his fears about going into a nursing home and so not
only did they get away with taking 8 years of extra payments but they also
avoided providing the care he had paid for.  AW
