The following outline is provided as an overview of and topical guide to autism:
Autism spectrum disorder – a neurodevelopmental disorder that affects social interaction and communication, and involves restricted and repetitive behavior.
Autism can be described as all of the following:
Signs of autism are highly variable, and different individuals will have a different mix of traits. Some more common traits include:

These are conditions that people on the autism spectrum may experience more often than is typical.
Disorders formerly considered distinct, but now diagnosed as autism spectrum disorder, include:
Asperger syndrome (AS), also known as Asperger's syndrome or Asperger's, is a term formerly used to describe a neurodevelopmental condition characterized by significant difficulties in social interaction and nonverbal communication, along with restricted, repetitive patterns of behavior and interests. Asperger syndrome has been merged with other conditions into autism spectrum disorder (ASD) and is no longer considered a stand-alone diagnosis. It was considered milder than other diagnoses which were merged into ASD due to relatively unimpaired spoken language and intelligence.
A gluten-free casein-free diet, also known as a gluten-free dairy-free diet, is a diet that does not include gluten, and casein. Despite an absence of scientific evidence, there have been advocates for the use of this diet as a treatment for autism and related conditions.
The diagnostic category pervasive developmental disorders (PDD), as opposed to specific developmental disorders (SDD), was a group of disorders characterized by delays in the development of multiple basic functions including socialization and communication. It was defined by the Diagnostic and Statistical Manual of Mental Disorders (DSM), and the International Classification of Diseases (ICD).
Developmental disorders comprise a group of psychiatric conditions originating in childhood that involve serious impairment in different areas. There are several ways of using this term. The most narrow concept is used in the category "Specific Disorders of Psychological Development" in the ICD-10. These disorders comprise developmental language disorder, learning disorders, developmental coordination disorders, and autism spectrum disorders (ASD). In broader definitions, attention deficit hyperactivity disorder (ADHD) is included, and the term used is neurodevelopmental disorders. Yet others include antisocial behavior and schizophrenia that begins in childhood and continues through life. However, these two latter conditions are not as stable as the other developmental disorders, and there is not the same evidence of a shared genetic liability.
Pervasive developmental disorder not otherwise specified (PDD-NOS) is a historic psychiatric diagnosis first defined in 1980 that has since been incorporated into autism spectrum disorder in the DSM-5 (2013).
Childhood disintegrative disorder (CDD), also known as Heller's syndrome and disintegrative psychosis, is a rare condition characterized by late onset of developmental delays—or severe and sudden reversals—in language, social engagement, bowel and bladder, play and motor skills. Researchers have not been successful in finding a cause for the disorder. CDD has some similarities to autism and is sometimes considered a low-functioning form of it. In May 2013, CDD, along with other sub-types of PDD, was fused into a single diagnostic term called "autism spectrum disorder" under the new DSM-5 manual.
Diagnoses of autism have become more frequent since the 1980s, which has led to various controversies about both the cause of autism and the nature of the diagnoses themselves. Whether autism has mainly a genetic or developmental cause, and the degree of coincidence between autism and intellectual disability, are all matters of current scientific controversy as well as inquiry. There is also more sociopolitical debate as to whether autism should be considered a disability on its own.
Autism spectrum disorder (ASD) is a neurodevelopmental disorder that begins in early childhood, persists throughout adulthood, and affects two crucial areas of development: social communication and restricted, repetitive patterns of behavior. There are many conditions comorbid to autism spectrum disorder such as attention-deficit hyperactivity disorder and epilepsy.
Neurodiversity is a framework for understanding human brain function that recognizes the diversity within sensory processing, motor abilities, social comfort, cognition, and focus as neurobiological differences. The neurodiversity paradigm argues that diversity in human cognition is normal and that some conditions generally classified as disorders, such as autism, are differences and disabilities that are not necessarily pathological.
The autism rights movement, also known as the autistic acceptance movement, is a social movement allied with disability rights that emphasizes a neurodiversity paradigm, viewing autism as a disability with variations in the human brain rather than as a disease to be cured. The movement advocates for several goals, including greater acceptance of autistic traits and behaviors; reforms of services – i.e. services that focus on improving quality of life and well-being instead of suppression and masking of autistic traits that are adaptive or not harmful or imitations of social behaviors of allistic (non-autistic) peers ; the creation of social networks and events that allow autistic people to socialize on their own terms; and the recognition of the autistic community as a minority group.
High-functioning autism (HFA) was historically an autism classification where a person exhibits no intellectual disability, but may experience difficulty in communication, emotion recognition, expression, and social interaction.
Autism therapies include a wide variety of therapies that help people with autism, or their families. Such methods of therapy seek to aid autistic people in dealing with difficulties and increase their functional independence.
Societal and cultural aspects of autism or sociology of autism come into play with recognition of autism, approaches to its support services and therapies, and how autism affects the definition of personhood. The autistic community is divided primarily into two camps; the autism rights movement and the pathology paradigm. The pathology paradigm advocates for supporting research into therapies, treatments, and/or a cure to help minimize or remove autistic traits, seeing treatment as vital to help individuals with autism, while the neurodiversity movement believes autism should be seen as a different way of being and advocates against a cure and interventions that focus on normalization, seeing it as trying to exterminate autistic people and their individuality. Both are controversial in autism communities and advocacy which has led to significant infighting between these two camps. While the dominant paradigm is the pathology paradigm and is followed largely by autism research and scientific communities, the neurodiversity movement is highly popular among most autistic people, within autism advocacy, autism rights organizations, and related neurodiversity approaches have been rapidly growing and applied in the autism research field in the last few years.
Classic autism, also known as childhood autism, autistic disorder, (early) infantile autism, infantile psychosis, Kanner's autism, Kanner's syndrome, or (formerly) just autism, is a neurodevelopmental condition first described by Leo Kanner in 1943. It is characterized by atypical and impaired development in social interaction and communication as well as restricted, repetitive behaviors, activities, and interests. These symptoms first appear in early childhood and persist throughout life.
Autism, also called autism spectrum disorder (ASD) or autism spectrum condition (ASC), is a neurodevelopmental disorder characterized by symptoms of deficient reciprocal social communication and the presence of restricted, repetitive, and inflexible patterns of behavior that are impairing in multiple contexts and excessive or atypical to be developmentally and socioculturally inappropriate. Other common signs include difficulty with social interaction, verbal and nonverbal communication, along with perseverative interests, stereotypic body movements, rigid routines, and hyper- or hypo-reactivity to sensory input. Autism is clinically regarded as a spectrum disorder, meaning that it can manifest very differently in each person. For example, some are nonspeaking, while others have proficient spoken language. Because of this, there is wide variation in the support needs of people across the autism spectrum.
Autism-friendly means being aware of social engagement and environmental factors affecting people on the autism spectrum, with modifications to communication methods and physical space to better suit individual's unique and special needs.
Gunilla Gerland is a Swedish author and lecturer on the topic of autism. Her written works include Secrets to Success for Professionals in the Autism Field: An Insider's Guide to Understanding the Autism Spectrum, the Environment and Your Role and her autobiography A Real Person: Life on the Outside.
The history of autism spans over a century; autism has been subject to varying treatments, being pathologized or being viewed as a beneficial part of human neurodiversity. The understanding of autism has been shaped by cultural, scientific, and societal factors, and its perception and treatment change over time as scientific understanding of autism develops.
Nonverbal autism, also called nonspeaking autism, is a subset of autism spectrum disorder where the person does not learn how to speak. One study has shown that 64% of autistic children who are nonverbal at age 5 are still nonverbal 10 years later.
Social (pragmatic) communication disorder (SPCD), also known as pragmatic language impairment (PLI), is a neurodevelopmental disorder characterized by difficulties in the social use of verbal and nonverbal communication. Individuals who are defined by the acronym "SPCD" struggle to effectively indulge in social interactions, interpret social cues, and may struggle to use words appropriately in social contexts.
