Are you POA for either of them? When my mother-in-law starting showing signs of memory loss and confusion, I took her to her doctor (she’d been scammed over the phone, checked out by the county sheriff office for a wellness visit, so I convinced her we needed to go ‘to make sure you don’t have a UTI, that can cause confusion’). Within a few minutes convo, doc looked at me, said she has beginning dementia, I will write a letter giving you the right to invoke POA at once to keep her safe. 1/2
