Our mother began showing signs of dementia two years ago but our father became ill throughout the year and then passed away. Because of my Dad's condition, my Mom's mental decline was put on the back burner because my Dad was the best one to talk to her about it and we were waiting for his health to improve to do so. Now, no one has approached our Mom with her obvious decline because of her hostile moods and withdrawal when it's brought up. We had her scheduled to see a geriatric psychiatrist to make a diagnosis and hopefully, use some meds to slow her progression, but Mom refused to keep her appointment. Now, it's not safe for her to be driving and we're concerned about her safety with living alone. Is there someone available to give us some professional advice about how to handle this situation and what would work best?
