Actually, what you describe is not really abuse when it comes to elder abuse and it sounds more like he is frustrated dealing with her and is being more of the latter of your claims. While he may be controlling her, if you complain he is withholding cigarettes from someone who is having a hard time breathing or yelling at her (even cursing) to call when she needed something, Family Services is likely not going to do much other than create hard feelings with your brother and maybe even your mom.
