She was diagnosed with Alzheimer's in 2013. She was fine for a long time, but ended up having to have her left knee and hip replaced in 2015. Before that, the orthopedic surgeon had given her steroids to try to help and it seemingly caused an abrupt deterioration in her cognitive state and increased confusion and disoriention. Afterward, she largely recovered. Then in early 2016 she abruptly became incontinent and lost her ability to even so much as stand up or sit up. She had been able to walk with a walker before. I realize, of course, that this isn't a medical site, but the background seemed necessary before getting to the actual problem I need help with and advice on. I had to have her taken to the ER this Sunday because she abruptly projectile vomited and I was afraid she might have aspirated some of her food, which of course would cause Pneumonia, and I wanted to stop that from happening if I could. The right side of her face was sagging very slightly and I asked them to check to see if she'd been having one or more mini strokes. So, they did a CT scan, which showed she had enlarged ventricles in her brain. The doctor wanted to do an MRI to verify if she had normal pressure hydrocephalus, which is a treatable condition, unlike Alzheimer's. They did the MRI, and had a neurologist teleconference with me in the hospital room yesterday. He said that while there are no guarantees, of course, it was possible that at least SOME of her dementia might actually be from the NPH, and that if so, relieving the pressure could help alleviate at least some of her dementia. Obviously I'm not expecting it to do a thing about any symptoms caused by Alzheimer's, nor to affect the progression of Alzheimer's, either. He said that instead of immediately doing brain surgery to install a shunt, that he'd recommend we have a spinal tap done, where they'd withdraw a bit more CSF than is normally done with spinal taps, so as to temporarily relieve some of the pressure in her ventricles. He said he'd want to have physical therapy do an evaluation BEFORE the tap, and then do another a few hours afterward, so as to have demonstrable evidence that it did or did not improve her cognitive state. My a**hole of an excuse for a brother has POA and he refuses to allow the tap. He claims the doctor is trying to run up unnecessary charges and that there's no reason to believe it would be of any medical benefit, and that it would just be causing her unnecessary pain and stress. It's ridiculous. Plus, the neurologist wouldn't even be doing the tap, he was just a consultant. He'd even said that with respects to the actual surgery, to install a shunt to drain the excess fluid, he would not go that route unless there was some very convincing evidence or reason to believe that it would be of great benefit to her. That doesn't sound like a scam to me. Is there anything that can be done to get him overruled so she can get the tap that would let us know if she could be helped? I'm honestly just utterly stunned and in disbelief that he wouldn't try to get his elderly mother any help that would possibly relieve her suffering a little bit for a while. Blows my mind.
