Agree, I've seen and heard that also and it was not true at all. Trusting medical care staff to give proper medical care for a loved relative is dangerous, imho for heart and soul. We need to advocate for our loved ones.
I have a loved one in Alzheimer care and am very impressed with the care they give all of the residents. Many of the caregivers are young people who sought this as their life’s calling and they are doing amazing work with these people... many who have no family or friends to even give an hour of their time in a month.
