So, if you've been following me, things have taken a turn for the worse... Dad (91, Parkinson's, depression, moderate cognitive issues) has been in assisted living since March (after going to the hospital with blood clots), while stepmom (88, cancer) has continued living at home. Dad has become increasingly concerned that stepmom has been having an affair. He passed out after dinner out at a restaurant last week, and went back to the hospital, diagnosed with low blood pressure and irregular heartbeat. Medical issues stabilized, but mental issues increased dramatically. Now says strangers are living in the house, and called the police to report as such. Became increasingly hostile towards staff (and myself, my brother, stepmom, and stepsister), and is now in a geriatric psych ward (the best in Massachusetts, I'm told--and I'm in Michigan) being diagnosed. Most recent conversations involved him disowning me and requesting I never speak to him or see him again. I know it's the dementia talking--but, of course, despite saying, "I'll remember everything and fix my will" he called again today. Should I even talk to him? Don't think he's seen a psychiatrist yet, and wondering if I should wait for his guidance. Fortunately, I have health care proxy and power of attorney. I have told him he is not 100% physically healthy, and he is there under doctor's orders. I reminded him we had the same conversation three hours earlier. Social worker has said they will look at cutting back his antidepressants and adding anti-anxiety meds, and that there will be more tests. What else can/should I do?
