Child to parent abuse

[complicatedsitu]

I have searched through threads on this and can find a lot of threads of experiences of teenager - parent abuse. Unfortunately my brother is 32. He is violent, aggressive and manipulative towards my mother. They live close to each other and I live a 10 hour drive away. I'm lost. I think it's been going on for a while but I've only just found out. Her GP knows and she is being supported. But I'm worried for her. What can I do?

Thread is from last year @Mrssnips. I didn’t say it was. I said the person being abused needed to be the one to act. And asked how they were being abused given this person doesn’t live with them. Eg do they have access to bank accounts? Are they using emotional blackmail?

Didn't know it was from last year, - but there is a known phenomenon of Elder Abuse, and it is certainly a safeguarding issue. Other thing is - the post is still up there and others might be searching for advice and information and come across the thread and get something from everyone's answers don't you think?
