Asperger syndrome (AS), also known as Asperger's syndrome, formerly described a neurodevelopmental condition characterized by significant difficulties in social interaction and nonverbal communication combined with restricted and repetitive patterns of behavior and interests. The syndrome has been merged with other conditions into autism spectrum disorder (ASD) and is no longer considered a stand-alone diagnosis. It was considered to differ from other diagnoses that were merged into ASD by relatively unimpaired spoken language and intelligence.
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).
Relationship Development Intervention (RDI) is a trademarked proprietary treatment program for autism spectrum disorders (ASD), based on the belief that the development of dynamic intelligence is the key to improving the quality of life for autistic people. The program's core philosophy is that autistic people can participate in authentic emotional relationships if they are exposed to them in a gradual, systematic way. The goal of treatment is to systematically build up the motivation and tools for successfully interacting in social relationships, to correct deficits in this area that are thought to be common to all autistic people.
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).
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 disorders (ASD) are neurodevelopmental disorders that begin in early childhood, persist throughout adulthood, and affect three crucial areas of development: communication, social interaction and restricted patterns of behavior. There are many conditions comorbid to autism spectrum disorders such as attention-deficit hyperactivity disorder and epilepsy.
Bernard Rimland was an American research psychologist, writer, lecturer, and influential person in the field of developmental disorders. Rimland's first book, Infantile Autism, sparked by the birth of a son who had autism, was instrumental in changing attitudes toward the disorder. Rimland founded and directed two advocacy groups: the Autism Society of America (ASA) and the Autism Research Institute. He promoted several since disproven theories about the causes and treatment of autism, including vaccine denial, facilitated communication, chelation therapy, and false claims of a link between secretin and autism. He also supported the ethically controversial practice of using aversives on autistic children.
The following outline is provided as an overview of and topical guide to autism:
The epidemiology of autism is the study of the incidence and distribution of autism spectrum disorders (ASD). A 2022 systematic review of global prevalence of autism spectrum disorders found a median prevalence of 1% in children in studies published from 2012 to 2021, with a trend of increasing prevalence over time. However, the study's 1% figure may reflect an underestimate of prevalence in low- and middle-income countries.
Peter Szatmari is a Canadian researcher of autism and Asperger syndrome.
Social Stories were devised as a tool to help individuals with ASD better understand the nuances of interpersonal communication so that they could "interact in an effective and appropriate manner". Although the prescribed format was meant for high functioning people with basic communication skills, the format was adapted substantially to suit individuals with poor communication skills and low level functioning. The evidence shows that there has been minimal improvement in social interaction skills. However, it is difficult to assess whether the concept would have been successful if it had been carried out as designed.
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, formally called autism spectrum disorder (ASD) or autism spectrum condition (ASC), is a neurodevelopmental disorder characterized by deficits in social communication and social interaction, and repetitive or restricted patterns of behaviors, interests, or activities, which can include hyper- and hyporeactivity to sensory input. Autism is 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.
This relationship between autism and memory, specifically memory functions in relation to Autism Spectrum Disorder (ASD), has been an ongoing topic of research. ASD is a neurodevelopmental disorder characterised by social communication and interaction impairments, along with restricted and repetitive patterns of behavior. In this article, the word autism is used to refer to the whole range of conditions on the autism spectrum, which are not uncommon.
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.
Sex and gender differences in autism exist regarding prevalence, presentation, and diagnosis.
Nonverbal autism is a subset of autism spectrum where the person does not learn how to speak. It is estimated that 25% to 50% of children diagnosed with autism spectrum never develop spoken language beyond a few words or utterances.
Social (pragmatic) communication disorder (SPCD), also known as pragmatic language impairment (PLI), is a neurodevelopmental disorder characterized by significant difficulties in the social use of verbal and nonverbal communication. Individuals with SPCD struggle to effectively engage in social interactions, interpret social cues, and use language appropriately in social contexts. This disorder can have a profound impact on an individual's ability to establish and maintain relationships, navigate social situations, and participate in academic and professional settings. Although SPCD shares similarities with other communication disorders, such as autism spectrum disorder (ASD), it is recognized as a distinct diagnostic category with its own set of diagnostic criteria and features.
