Elder Abuse?

[NoahsMommy]

I know this is totally off subject...but this has been bothering me for quite awhile and I wanted to know if anyone had some advice on the subject.

I know someone who cares for her 90-something mother. I constantly hear her saying unkind things about her. When she is on the phone with the day-time caretaker (family member) they constanly are laughing (meanly) at what stupid thing the mother did that day. They are always complaining about her actions, needs, etc. Her mother has dementia so badly that she is on anti-psychotic drugs. Now, it's to the point of abuse, I feel. She needs to be in a facility where the mother-daughter line isn't crossed and she wont be given a hostile attitude when she needs help.

What can I do? The person knows her mother needs to be in a home, but makes excuses as to why she's not in one.
