Re: Daily!?! RFC begs to differ
Sorry to hear that you're going through this. Regardless of what the reason is for you mother's cognitive decline, it's not fun seeing someone you care about deeply deteriorate over time.
I would urge you (and anyone else reading this) to arrange for powers of attorney for your parents and other loved ones BEFORE you end up in a situation when they are no longer competent to fend for themselves or look out for their own interests. I don't know if this document has a particular name in English, but in my language there's a specific form of PoA that you can issue that allows named relatives, family members or other appointed guardians to step in and help a person make decisions if they are no longer able to take care of themselves. This will allow you to step in and help your mother when she can no longer make the appropriate decisions for herself.
To be brought up, discussed and executed with the tenderest care and understanding for your mother's wishes, of course.
