[Done] Scott is 7 years old. Within the first five years of his life, he would display outbursts of behaviour that challenges, would fidget, and would not give eye contact or listen. He would place himself in very harmful situations and be forgetful. He was when his parents took him to see the GP and after a series of tests it was confirmed that he had ADHD. At the age of 7, he was put on Dexamphetamine, which initially had some positive impact. When he turned 8, the medication appeared to stop having any impact on Scott's behaviour, so his parents were referred to see a psychiatrist who prescribed Ritalin. One day, whilst Scott was at school, his mum received a phone call from the headteacher informing her that he couldn't catch Scott, so she asked him what he was doing and he said, "Chasing Scott to get him inside". Mrs Hanson, Scott's mum, explained to the headteacher that by chasing her son he was getting a buzz out of all of the attention he was receiving and suggested to the head that he went inside and waited for Scott to return to class. Upon his return Scott sat under the headteacher's table playing with a paperclip. Within ten minutes Scott returned to his classroom with his 1-1 support worker and continued to complete his schoolwork. On one occasion whilst at home, Mrs Hanson could hear shouting. Upon inspection she found Scott sat on the roof of their house shouting out at a neighbour. She asked Scott to get down and sent her husband up to help him down. On another occasion, Mrs Hanson grounded Scott and told him he wasn't allowed to go to Scouts, so he jumped out of the bedroom window and ran off to Scouts. Mrs Hanson did not chase him, as she knew she would be putting her son in more danger by doing so. She walked some yards behind him and once she saw he was safe in the Scouts hut, she returned home. When Scott returned home, his parents spoke to him and asked Scott to explain his feelings and actions. Explain how to maintain a supportive environment for a child or young person.
