Autism is a lifelong developmental disability that affects how people perceive the world and interact with others.
Autistic people see, hear and feel the world differently to other people. If you are autistic, you are autistic for life; autism is not an illness or disease and cannot be ‘cured’. Often people feel being autistic is a fundamental aspect of their identity.
Autism is a spectrum condition or a continuum. All autistic people share certain difficulties, but being autistic will affect them in different ways. Some autistic people also have learning disabilities, mental health issues or other conditions, meaning people need different levels of support. All people on the autism spectrum learn and develop. With the right sort of support, all can be helped to live a more fulfilling life of their own choosing.
The characteristics of autism vary from one person to another, but in order for a diagnosis to be made, a person will usually be assessed as having had persistent difficulties with social communication and social interaction and restricted and repetitive patterns of behaviours, activities or interests since early childhood, to the extent that these “limit and impair everyday functioning”.
Over the years, different diagnostic labels have been used, such as autism, autism spectrum disorder (ASD), autism spectrum condition (ASC), classic autism, Kanner autism, pervasive developmental disorder (PDD), high-functioning autism (HFA), Asperger syndrome and Pathological Demand Avoidance (PDA). This reflects the different diagnostic manuals and tools used, and the different autism profiles presented by individuals. Because of recent and upcoming changes to the main diagnostic manuals, ‘autism spectrum disorder’ (ASD) is now likely to become the most commonly given diagnostic term.
The exact cause of autism is still being investigated. Research into causes suggests that a combination of factors – genetic and environmental – may account for differences in development. Autism is not caused by a person’s upbringing, their social circumstances and is not the fault of the individual with the condition.
Here is a helpful video explaining what ASD is and what causes it.
