Understanding autism
Autism is a neurodevelopmental condition that is present from birth, although autistic traits can be recognised at any age.
Autism represents a spectrum of differences, which means that autistic people all have different strengths and can face different challenges. However, there are some common signs of autism and particular traits which are recognised during the diagnosis process.
Autism spectrum disorder (ASD) or autism spectrum condition (ASC) are the medical terms used to describe autism. The term Asperger syndrome was historically used to describe a particular form of autism – usually in people who do not have significant language developmental delay or a learning disability – but it is no longer given as a distinct diagnosis, and is now considered to be part of the different autism profiles that exist within the overarching diagnosis of ASC. The name Asperger syndrome is also avoided by many now due to what is known about Hans Asperger’s history (read more about the term Asperger syndrome on the National Autistic Society website).
It is estimated that at least 1 in 100 people are autistic, although more recent studies indicate that autism may be much more common than this.
Autism support
A range of support is available for autistic children, young people and adults. This includes local specialist organisations, peer support groups, autism charities, advocacy services, emotional health support services and more. Help is also available for family members who need it, with a range of peer-led groups and organisations available in the Dorset community.

Autistic traits
Autism is a spectrum condition that affects people in different ways. It is not linear, and the strengths and challenges that exist as part of someone’s autism can change over their lifetime.
To learn more about the signs of autism in children, young people and adults visit Signs of autism (NHS) or What is autism? (National Autistic Society).
How is autism diagnosed?
The formal diagnostic criteria for autism look at two key sets of behaviours (to include social, emotional, cognitive and sensory behaviours):
- Cluster A – Differences in social communication, social motivation and social interaction (which can create challenges)
- Cluster B – Repetitive and restrictive patterns of behaviours or interests (which include sensory experiences).
If you believe that you or your child are displaying signs of autism and you want to find out more, you can learn more about autistic traits on this page. If you would like to talk to someone about it, you can also speak to the following professionals:
- Your health visitor for children under five
- The Special Educational Needs Coordinator (SENCO) for children in school – if you don’t know who that is, the school’s office will be able to help
- Your GP or another healthcare professional.
They may suggest an autism assessment.
Some people may recognise signs of autism in themselves but choose not to pursue a diagnosis. If you feel you may be autistic but don’t want a diagnosis, there is plenty of autism support still available should you need it. Read more about autism support in the support and advice section of this website.
The Community Adult Aspergers Service (CAAS) oversees the diagnosis process for adults. Find out more about CAAS services on the Dorset HealthCare website.
If you are under the care of the Community Mental Health Team (CMHT) a diagnosis will be overseen by a professional within that team.

About autism assessments
An autism assessment will be carried out by autism specialists. You may need to wait several months for an appointment, and it can take some time for the assessment to be completed, as a range of professionals need to be involved.
If you need support whilst you’re waiting for an appointment, or for an assessment to be completed, you can talk to a healthcare professional about accessing support, or find out more about help available in Dorset in the support and advice section of this website.
All autism assessments are carried out using a set of criteria for autism, found in diagnostic manuals called the ICD-10 and the DSM-5. You can read more about these in the National Autistic Society’s guide to diagnostic criteria.
