Autism, now called autism spectrum disorder (ASD), is a neurodevelopmental disorder. ASD is a developmental disability caused by differences in your child's brain. People with ASD may behave, interact and learn in ways that are different from other people.
Spectrum model
Before the DSM-5 (2013) and ICD-11 (2022) diagnostic manuals were adopted, what is now called ASD was found under the diagnostic category pervasive developmental disorder. The previous system relied on a set of closely related and overlapping diagnoses such as Asperger syndrome and Kanner syndrome.
In the autism community, many self-advocates and their allies prefer terminology such as “Autistic,” “Autistic person,” or “Autistic individual” because we understand autism as an inherent part of an individual's identity — the same way one refers to “Muslims,” “African-Americans,” “Lesbian/Gay/Bisexual/Transgender/ ...
Autism is now understood as a complex, invisible condition that a person is born with. It is a developmental condition which means that the way a person communicates, interacts and understands other people, and the world, is different to those who do not have the condition.
Autism is highly variable – the word 'spectrum' refers to how autism is experienced differently by different people. Autism is considered a spectrum because it's different for every autistic person – some autistic people might need more support than others to live the lives they want to lead.
The diagnosis was retired in the next editions of these publications, the DSM-5 in 2013 and the ICD11 in 2019, when it was folded into the diagnosis of 'autism spectrum disorder'. As a result of these changes, Asperger syndrome should no longer be given as a diagnosis.
The name for Asperger's Syndrome has officially changed, but many still use the term Asperger's Syndrome when talking about their condition. The symptoms of Asperger's Syndrome are now included in a condition called Autism Spectrum Disorder (ASD).
Explain the Basics
You can explain that autism is usually associated with difficulty in social and communication skills, repetitive behaviors, and adherence to routine. It also can be accompanied by sensory sensitivities and challenges with paying attention.
Autism is very distinct from ADHD, but the core symptoms of ADHD-Combined type, i.e., attention deficit, impulsivity, and hyperactivity, would appear to also be features of autism. ASD and ADHD are neurobiological disorders characterized by similar underlying neuropsychological “deficits”.
Autism Spectrum Disorder (ASD) is a developmental disability that affects a person's ability to engage and interact with the world around them. ASD is a common developmental disability that affects around 1 in every 100 to 110 people.
Starting in the 1990s, milder forms were recognized, including Asperger's syndrome (now called high-functioning autism). Then in 2013, the American Psychiatric Association grouped all autism-related disorders together as ASD. Still, you may hear some people who aren't doctors continue to use terms like Asperger's.
ASD and OCD can sometimes have similar symptoms. However, they are different conditions. Research from 2015 found that 17% of people with ASD also have OCD. This is higher than the percentage of people with OCD in the general population.
Some developmental health professionals refer to PDD-NOS as “subthreshold autism." In other words, it's the diagnosis they use for someone who has some but not all characteristics of autism or who has relatively mild symptoms.
The principal difference between autism and what was once diagnosed as Asperger's is that the latter features milder symptoms and an absence of language delays. Most children who were previously diagnosed with Asperger's have good language skills but may have difficulty “fitting in” with their peers.
Autism is not an illness
It means your brain works in a different way from other people. It's something you're born with. Signs of autism might be noticed when you're very young, or not until you're older. If you're autistic, you're autistic your whole life.
There is not just one cause of ASD. There are many different factors that have been identified that may make a child more likely to have ASD, including environmental, biologic, and genetic factors.
Someone who is considered a savant may be especially skilled in art, math, music, memory recall, or another subject. Savant syndrome is commonly associated with autism but can occur alongside other conditions.
Asperger's syndrome.
This is on the milder end of the autism spectrum. A person with Asperger's may be very intelligent and able to handle their daily life. They may be really focused on topics that interest them and discuss them nonstop. But they have a much harder time socially.
About stimming and autism
Stimming might include: hand and finger mannerisms – for example, finger-flicking and hand-flapping. unusual body movements – for example, rocking back and forth while sitting or standing. posturing – for example, holding hands or fingers out at an angle or arching the back while sitting.
Asperger's Syndrome is a form of autism, which is a lifelong disability that affects how a person makes sense of the world, processes information and relates to other people. Autism is often described as a spectrum because the condition affects people in many different ways and to varying degrees.
If someone in your family has autism spectrum disorder (ASD), you may be more likely to have a child with ASD. ASD can look very different from person to person, so taking a careful family health history can be important for early diagnosis.
