"Asperger's Syndome & mental health"

Our son suffers with Asperger's Syndrome and has depression. He visited the A&E with his father after a self harming incident. He was initially cleaned up and left in the waiting room for over five hours. His blood pressure and temperature was not taken or was he reviewed to his distress levels. Thankfully, his father has a calming influence and was able to reassure him but I feel so angry that he had to wait for over five hours before treatment. Isn't there a procedure whereby when a person comes into A&E with mental health problems that the crisis team is alerted? When he eventually saw the doctor it was only then was my son asked if he wanted to see the crisis team. He was treated very well by the doctor and nurse but this doesn't stop the concern that we feel towards his initial treatment. Naturally, our son made a decision to leave the A&E and come home simply because he was so exhausted and distressed over his experience. People who have mental health problems or multiple disabilities deserve better treatment. As a family we feel disappointed and reluctant to give a higher rating we hope that situations like ours doesn't happen to other families.
