Pp here (hit send too soon). Also, I'd talk to the audiologist about hearing aids that are, I guess, easier for people with dementia/limited dexterity. My dad currently has those tiny, in ear ones with different settings and he is CONSTANTLY having issues with them.
He doesn't have the hand capabilities to get them in well, they fall out, he plays with the settings and renders them useless (he has Parkinsons and related dementia). He is going to the VA soon (I just got him in) for new ones and I am going with him and will ask for simple ones, hopefully over ear ones (harder to lose). Hopefully they have 'plug and play' ones for folks like our dads LOL
