Autistic Children and young people (CYP) experience higher rates of mental health problems, including anxiety and depression, than their neurotypical peers. Yet, often mental health assessment and support is lacking for autistic CYP as assessment tools and evidence-based interventions have typically been developed with neurotypical population needs in mind. Following a narrative matters style, this article outlines the lack of recognition given in mental health services towards autistic CYP attempting to access support, highlighting some future priorities in service delivery. Issues relating to health professionals misinterpreting and mis-labelling autistic CYP experiences, the impact that this has upon those attempting to gain mental health support and possible changes that can be implemented at minimal cost both financially and to service delivery design and implementation are highlighted.
