Autism Spectrum Disorder (ASD) can vary in severity of symptoms, age of onset, and the presence of various features such as language and intellectual ability. The manifestations of ASD can differ considerably across individuals. Even though there are strong and consistent commonalities, especially in social deficits, there is no single behavior that is always present in every individual with ASD and no behavior that would automatically exclude an individual from diagnosis of ASD.
Autism Spectrum Disorder affects each individual differently and at varying degrees – this is why early diagnosis is so crucial. ASD is a lifelong condition, but early intervention contributes to lifelong positive outcomes.
