What should I do?

It is brutal, and more so for loving caregivers. You might want to see if his physician might try a change of medication as a possible interim step.

How does your mom react to his outbursts? Would he attempt to assault her physically? Her safety and comfort are something you can focus on, since you can develop strategies to protect her. As you know, you can’t reason with your father.

If you decide you must have him removed, you will probably find that both he and your mom will be upset with the change.

Remember as you attempt to address these painful circumstances that your job is to make a choice from a group of less than satisfactory options. Your job is just todo the best you can.

It sounds like you need to protect your mother. It's possible they can figure out the right balance of medication or find some infection contributing to this behavior in the hospital but let the professionals figure that out. No doubt if your father were in his right mind he would want you to to protect your mother from this abuse and possible danger. I can only imagine how hard this is for you, sending strength your way.

If you can get him help to stop the nonsense with your mom by all means do it.

This is an awful disease and causes us to do many things we never dreamed we would do or need to do.

Best of luck. It is a horrible journey for everyone. Hugs!

I would ASAP! This is abuse on both parts.
