I'm fed up of hearing people discussing these disorders saying they are made up labels for naughty children. Clearly these people have not had to fight for a diagnosis else they would know such diagnoses aren't handed out willy nilly after meeting a child for 5 minutes but can take years of assessments!
If your child has one of these disorders do they also have AS, Autism, ADHD etc or is it possible to have one of these disorders on it's own IYSWIM.
