"Accident and Emergency - Patients with Alzheimer's"

I had to attend the hospital on Saturday evening with my father who is in a wheelchair, has COPD, Alzheimer's and vascular dementia. My father, who lives in Res Care, had an infected finger and we were advised by the nurses who were called to the home to take him to hospital. We waited 3 hours to be seen by a doctor who gave my father some antibiotics. My concern is that there is no consideration given to elderly patients, my father is 86, who have Alzheimer's, he sat for 3 hours in a wheel chair. Could patients with Alzheimer's be treated earlier than other patients with minor complaints? Over a year ago I attended with my mother who also had Alzheimer's, she was mobile and needed to walk all the time, luckily we were accompanied by a carer from her home. My mother had Lewey Bodies so she could be disruptive. It was late at night and my mother kept asking for something to eat and I eventually had to ask other people waiting if they had anything, luckily one woman had some biscuits. I am sure that my mother's behaviour must have irritated some people who were feeling ill. My mother at that time looked very old, and frail she must have weighed about 6 stone - again could elderly people please be seen before those with minor complaints?
