Good topic but don't expect much from the discussion here. My mother has middle stage dementia. Certainly don't talk much about it here with all the thread trashers.
This reminds me of a moment long past..
When I was in my twenties, my dad passed after a long battle illness. At the time, my grandmother, his mom, was in her eighties. Long twilighting from dementia, rarely present if at all.
On the day of his funeral, I'm a wreck, etc.. a d my aunt's bring her to the coffin to say goodbye. She had been very distanced from the events leading up to this...
In a moment I'll never forget.... It was as though she willed herself back in to the now. You could see it...in her face, her eyes..a sheer force of will back to lucidity.. in the moment she turns to the family and says... It's is the greatest sadness for a mother to bury her own child. The greatest sadness..
Then....like it took all of her energy....poof....gone again. Never really returned after that.
FWIW, I carry with me to this day that memory of the power of love manifest...which I took to mean that those we love are always still there, to the last and deserving of every compassion to the end
FWIW.
