My mother is 99 and my brother lives with her. We/I know he is verbally abusing her. He makes her sit in the kitchen all day with all the doors and windows open. We don’t want her going in a home and she forgets within seconds how he shouts and swears at her. He has taken complete control of her . The only thing she does now is go to the loo on her own. Apparently she does idolise him and won’t hear anything said against him. But this shouting at her all the time upsets us.
