A diagnosis  provides a meaningful understanding of an individual's profile of strengths, differences, and support needs. A diagnosis is not intended to define the person or limit their potential. Rather, it helps explain patterns of behaviour, communication, sensory experiences, and emotional responses that may have been present throughout development.

A diagnosis can guide appropriate interventions, inform educational and therapeutic planning, facilitate access to supports and accommodations where appropriate, and help individuals, families, and professionals develop a shared understanding of the person's needs.

Within a neuro-affirming framework, a diagnosis recognises neurodevelopmental differences rather than viewing them as deficits. It provides a foundation for promoting self-understanding, reducing unnecessary barriers, and supporting individuals to thrive in environments that recognise and value neurodiversity.
