Thanks for the great idea, @colleenyoung. I think a specific discussion is warranted given the challenges dementia can present to caregivers.
My mother-in-law (MIL) had what was finally determined to be frontal temporal dementia. She had the disease from her 60s until she passed away at 86. My wife was especially involved in her mom's caregiving due to some serious denial in other family members and a GP who refused to diagnose, even when significant deficits were obvious (mistaking the UPS deliveryman for her husband and not knowing the difference between roads and sidewalks). The most unfortunate result of this, to me, was the lost time when my MIL and her family could have been having meaningful and important discussions about significant matters of importance to her and them.
In my wife's years of fighting her brain cancer, she, too, exhibited many of the aspects of mental degradation and physical losses one would affiliate with a dementia patient.
As an aside, for several years I worked for the national Alzheimer's Association raising money for their research programs nationwide.
I wish everyone struggling with this disease and their caregivers and families strength and peace.
