    My mother is 85 in nursing home for dementia and Alzheimer’s. Suddenly she is acting out angrily and aggressively. Now they want to move her to a lock down unit. I believe this is being too hasty by Director of nurses and meet with her today at 1. I just came across your video and am now concerned she is having delirium. I don’t know what to do next. Thank u.
