I presently live with my aging parents, along with my husband and young son. My parents are slipping mentally, but I'm not sure if it's age or something more. Last night, my dad yelled at me for getting off work late, for my husband working late, and for our son being cranky. I hadn't even gotten my shoes off (required in the house) before I was thoroughly cussed out. My parents presently babysit part time for us, but I think that's going to be changing really soon - as is our living arrangements if I can get my in-laws to agree. Anyway, I'm the only child and I don't have power of attorney (my parents have refused to give me that). Is there any way I can talk to their doctors, particularly my dad's, to see about a mental evaluation? My dad is supposed to be on oxygen 24/7, but refuses and mostly uses it at night for his sleep apnea. My dad is normally grumpy, but last night he was significantly more aggressive than usual. Today and tomorrow our son is at my in-laws house, and I'm working on getting other arrangements made for the 3 of us.
Secondly, I appreciate the suggestions of writing to the doctor and seeing about an eval. I'm not allowed to attend any doctor appointments, probably for the same reason I'm not POA. But I will definitely call and/or write.
In that case, I would send a letter to his PCP or neurologist (preferably) and share your concerns, and perhaps suggesting that they schedule your father for an evaluation.
That doesn't address the issue of knowing what the eval might show, but you might want to raise that in the letter to the doctor, indicating you're planning for future arrangements and it would be helpful to know what kind of facility might be appropriate.
You're wise to remove your family from the unhealthy environment, especially since your father won't adhere to medical recommendations for oxygen use. The shortness of breath he probably experiences might be contributing to his nasty moods.
But I would definitely get out of there, not only for you, your husband and son's protection, but I suspect that conditions are only going to worsen until your father ends up in the hospital with respiratory complications.
And the babysitting arrangement needs to change; that's too much for an elderly couple to handle, and might be why your father's hostile to you and your family.
If you are able to go with him, I'd ask the doctor if he could refer him to a neurologist and a geriatric psychiatrist for evaluation.
