My mother moved from an Assisted Living facility to long-term care on Feb 1. When she moved in, she had memory problems associated with dementia but she was a good walker and pleasant to be around. Since she moved, she was confined to her room for a couple of weeks due to a flu outbreak in her unit. She has had UTI's, a cold and pneumonia and was diagnosed with depression at the end of March. She has been on antidepressants since March 25. In the last week, she has been disruptive and combative with other residents and staff and her personality has changed so dramatically that she is being moved to a more secure unit. I don't know how to handle her outbursts and what I should be advocating for on her behalf.
