Autism, also referred to as Autism Spectrum Disorder (ASD), is a neurodevelopmental disorder characterised by a range of characteristics, traits and challenges related to social interaction, communication, and repetitive behaviours. It is called a "spectrum" disorder because it manifests in a variety of ways and to varying degrees of severity. Each individual with autism is unique, and the term "spectrum" reflects the diversity of symptoms and strengths within the autistic population.

It's important to remember that the presentation of autism can vary widely, and each individual may experience a unique combination of strengths and challenges. Diagnosis is typically made based on behavioural observations and assessments, and early intervention and support can significantly improve outcomes.
