Re: abusive elderly father
So sorry to hear of your family problem. There could be many issues causing your fathers behaviour...frustration at not being in control of his life. There could also be underlying health issues. He might have had a mild stroke, he could have a tumor. All these are things that can bring out aggression, and if he has a predisposition to being aggressive, then this would only increase it.
Have you had him checked for any of the conditions I mentioned?
If he is just being mean and taking it out on your Mother (because he can), then as a family you must step in and help her. Let him know he is on notice to clean up his act, and if not then he has you to answer to. At your Mother's age she should not be put through this kind of stress. But please look into the possible health issues too. If we are not part of the solution...then we are part of the problem. GOOD LUCK.
