People with senile dementia, presenile dementia and bona fide Alzheimer's Disease will take on personality changes that cause them to act in ways that they would never have acted if they were their normal selves. I know of a wonderful pastor who developed Alzheimer's in his senior years and when the disease took full hold, he changed into a foul-mouthed and angry man, saying words that he would never let pass his lips before.
If you understood that the changes that these brain diseases cause in a personality, perhaps you would have more compassion for her. In her normal state in the pat, she may have been a perfectly lovely person to know. Perhaps it would behoove you to do some research on her life to give yourself some perspective.
It is a good thing that you work with partners. My oldest daughter worked nights in the lock down unit of an Alzheimer's wing of a large nursing home facility. She worked alone with the registered nurse of the entire floor including her wing outside of the locked area. They were once outfitted with cell phones to be used as an alarm call in case something happened. She would often be battered or kicked, but one night less than a year ago, she caught a large male patient wandering into a room where two women were asleep and so as usual, she went to distract him and to get him to come with her. He grabbed her arm tightly and she could not break free. he began to slam her head against the wall and for twenty minutes he did that continually, while she flailed and screamed, to no avail. The facility's administration had recently removed the cell phones from the staff saying they could no longer afford them. Finally my daughter broke free and ran for her life with him chasing her.
She was off work immediately for a serious concussion and continues now to be off work with a neck injury requiring injections into the occipital nerve, vestibular ear, which is permanent, fibromyalgia and PTSD, as well as nystagmus of the eyes. She is not the young woman I know any more, and her professionals say she will most likely never be able to work in the care giving field again...if anywhere. We are praying for healing!
So, these patients are merely a shell of their former selves, and you need to take every precaution against being injured, but at the same time be compassionate for the people they once were. In the past, I have also worked in the chronic care of a major hospital as a nurse, and have had these types of patients to deal with.
When these patients begin to act out, it cannot do harm to take spiritual authority over them and anything that may be driving them.
