So am I, new to the forum. I also have just started this journey, as an only child and also having to work, staying with Papi is not an option for me.
I'll tell you my story but if I were you definitely a new doc, a good primary physician, geriatric preferably; I know this is not easy but you need to try. It sounds like Dementia, or the dreaded Alzheimer's. She needs to be properly diagnosed. Papi had a bad fall, leading to sudural hematoma and surgery, during this event my Mom uped and died, just like that. He went to Rehab, doc insists it's not Alz, I am no Dr. but I know my Dad, and that wasn't him, his recovery from the surgery was short of miraculous, he is 80 years old. His memory is shot, he has terrible imbalance due to fall and incontinence. He never had to deal with any of this before, believe me recoup at home wasn't pretty. Apparently he had many mini strokes, leading to the fall. So, he recuperates at home with me (I was away from work for 2 months, I work for SAINTS). I contacted Aging Services in my State and voila found a PCH, in my heart I knew this was not what he needed but I had to get him to the States ASAP, no one else to take care of him but me, so on the plane we get. The PCH is 1 hour from my home sans traffic, so I immediately tell the owner, this is temporary, until I find something more appropriate and get him diagnosed. I lucked out and found a wonderful primary care physician, and I found this web site, the doc has diagnosed him with Alz and are working on proper meds to assist. And this web site provided numerous ALF and I found one that deals exclusively with Memory Care, he moved yesterday. He hasn't had the violent reaction yet, but yes the paranoia and extreme anxiety to go HOME to his home, he constantly forgets where he is, yet he seems to be acclimating OK so far, so it's in God's hands.
Please find a new doc. I hope this helps, I know this is going to be a very long road for you and me, many in this industry have been very kind to me, and insist as her care giver YOU must TAKE CARE OF YOU. I've been reading quite a bit about this unforgiving disease, and it does help to understand it better even though all patients have different issues. Blessings for you and your Mom. Be patient, this ride is just beginning. So, be persistent and vigilant. God Bless.
