Mom has advanced PD and is becoming more and more 'confused' or mixed up -- the nice words for impending dementia. Problem is I'm the only one who gets a ring side view of this. I here 98% of the time so I see all the crazy crap. She's sweet as pie for her phys therapist who comes 2X a wk for an hour and for the home care person who comes only 2X a wk for 4 hrs. She never unravels for them and is sweet as pie. I'm noticing more and more that mom's episodes of confusion are becoming to the point where I can't say anything without being accused of being mean and horrible when all I'm doing is trying to explain myself. Can these seniors turn it on and off like a faucet or am I being paranoid?
