Dementia spouse won't go to dr. unless I lie to the them about his late-stage symptoms. Any advice?

The doc not responding to my email with symptom list.
My husband is, unfortunately, one of those dementia sufferers that use deceit, denial, anger and verbally aggressive behavior to hide their fear of what is happening to them. I am convinced he has vascular dementia. He retains a good memory level - although his cognitive function is horrible and his mobility has declined to the point of making him house-bound. In a few short months, he has declined drastically from several mini-strokes brought on from a long history of heart-attacks, strokes and hypertension related issues. He also suffers from OCD, anxiety and depression.

Since his first stroke and heart-attack 10 years ago, I have been trying to get his doctors to listen to me about possible dementia symptoms, but he lies to them at each visit; turns on his polished charm and convinces them that I am making up everything I say. During his last hospital visit, a neurologist officially diagnosed him with dementia. Then, as his mobility declined and medicare told me I needed him to go get a mobility function eval from his GP. He refused to go to any doctor. This forced me to pay the full price of all safety and mobility equipment, which has been tough, since I had to close my 18yr old business to care for him full-time leaving us with just his retirement income. And this is juuust enough that we don't qualify for any aide programs.

Now...he has fallen so many times (always trying to prove he doesn't need to use the 'cripple' equipment as he puts it), he finally relented and told me I could make a doc apt. However, he refuses to go - if I tell the doctor the truth about his symptoms - other than those obvious to the doctor. So, I signed up for the doctor's patient portal; wrote a letter containing all the cognitive/mobility symptoms and then asked the doctor if I could count on him to work with me 'behind the scenes' - in order, to get my husband the medical care he needs. I explained to the doctor that this was necessary, because my husband said he would never go again, if I told any doctor "just how bad it is now".

2 weeks later...no response. I called his office asked his staff to simply have the doctor give me a yes or no answer to whether he was willing to not tell my husband that I shared the symptom list. They promised a call but I never got one and that was 2 months ago.

Now his paranoia, suspicions and fear are off the charts and he accuses me of wanting him to be declared incompetent; committed to a home and even die, during his anxiety attacks. After the episode, he is the sweetest thing and thinks I take great care of him. I know not to argue and smile a lot, but now he has been calling his two estranged adult children during these fear attacks, while i'm in the shower, etc., complaining about me. They tried to gain custody of my husband 10 years ago, while he was undergoing quintuple open-heart surgery following a stroke and corodidendorectomy. They said, "she only convinced the surgeon to do the surgery, so she could get attention!" (they are close to their mother and resent their father's remarriage) That would have been funny, except...they tried to beat down the Cardiac ICU door; called social services on me; made me leave my husband's critical care bedside to meet with the hospital administration and caused a ruckus that ended up with them banded from the hospital and further contact with my husband during his stay. My husband harbored deep resentment and anger over it - up until his recent cognitive decline. My relationship with them ended by their choice immediately after and my husbands relationship with them has been a once-a-month obligatory phone call, at best.

We both made POA, DPOA and Wills after that. Now, I am worried about how I can get my husband the best care and protect him from himself and others. All the while, fighting the same war with getting his doctors to even work with me. I'm so frustrated. LO wont let me attain any outside assistance; tell anyone he has dementia and even get the safety equipment he needs. What I HAVE gotten, I just bought using our retirement savings without telling him and I get yelled at for it almost every day. (But he IS using it and that's all that matters to me.)

Does anyone have any advice? I want to make the doc apt - even if he changes his mind and makes me cancel (which he does), but this is the ONLY doc he will go to, so switching to a new one probably isn't an option. What an I do?
