Asperger syndrome (AS), also known as Asperger's syndrome, formerly described a neurodevelopmental disorder characterized by significant difficulties in social interaction and nonverbal communication, along with restricted and repetitive patterns of behavior, interests, and activities. The syndrome has been merged with other disorders into autism spectrum disorder (ASD) and is no longer considered a stand-alone diagnosis. It was considered milder than other diagnoses that were merged into ASD due to 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).
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, motor disorders, and autism spectrum disorders. In broader definitions 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.
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.
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.
The following outline is provided as an overview of and topical guide to autism:
Thiomersal is a mercury compound which is used as a preservative in some vaccines. Anti-vaccination activists promoting the incorrect claim that vaccination causes autism have asserted that the mercury in thiomersal is the cause. There is no scientific evidence to support this claim. The idea that thiomersal in vaccines might have detrimental effects originated with anti-vaccination activists and was sustained by them and especially through the action of plaintiffs' lawyers.
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.
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.
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.
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.
Autism Speaks Inc. is an American non-profit autism awareness organization and the largest autism research organization in the United States. It sponsors autism research and conducts awareness and outreach activities aimed at families, governments, and the public. It was founded in February 2005 by Bob Wright and his wife Suzanne, a year after their grandson Christian was diagnosed with autism. The same year as its founding, the organization merged with Autism Coalition for Research and Education. It then merged with the National Alliance for Autism Research in 2006 and Cure Autism Now in 2007.
The Kennedy Krieger Institute is a nonprofit, 501(c)(3) tax-exempt, Johns Hopkins affiliate located in Baltimore, Maryland, that provides in-patient and out-patient medical care, community services, and school-based programs for children and adolescents with learning disabilities, as well as disorders of the brain, spinal cord, and musculoskeletal system. The Institute provides services for children with developmental concerns mild to severe and is involved in research of various disorders, including new interventions and earlier diagnosis.
Autism, formally called autism spectrum disorder (ASD) or autism spectrum condition (ASC), is a neurodevelopmental disorder marked by deficits in reciprocal social communication and the presence of restricted and repetitive patterns of behavior. Other common signs include difficulties with social interaction, verbal and nonverbal communication, along with perseverative interests, stereotypic body movements, rigid routines, and hyper- or hyporeactivity 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 spectrum disorder (ASD) refers to a variety of conditions typically identified by challenges with social skills, communication, speech, and repetitive sensory-motor behaviors. The 11th International Classification of Diseases (ICD-11), released in January 2021, characterizes ASD by the associated deficits in the ability to initiate and sustain two-way social communication and restricted or repetitive behavior unusual for the individual's age or situation. Although linked with early childhood, the symptoms can appear later as well. Symptoms can be detected before the age of two and experienced practitioners can give a reliable diagnosis by that age. However, official diagnosis may not occur until much older, even well into adulthood. There is a large degree of variation in how much support a person with ASD needs in day-to-day life. This can be classified by a further diagnosis of ASD level 1, level 2, or level 3. Of these, ASD level 3 describes people requiring very substantial support and who experience more severe symptoms. ASD-related deficits in nonverbal and verbal social skills can result in impediments in personal, family, social, educational, and occupational situations. This disorder tends to have a strong correlation with genetics along with other factors. More research is identifying ways in which epigenetics is linked to autism. Epigenetics generally refers to the ways in which chromatin structure is altered to affect gene expression. Mechanisms such as cytosine regulation and post-translational modifications of histones. Of the 215 genes contributing, to some extent in ASD, 42 have been found to be involved in epigenetic modification of gene expression. Some examples of ASD signs are specific or repeated behaviors, enhanced sensitivity to materials, being upset by changes in routine, appearing to show reduced interest in others, avoiding eye contact and limitations in social situations, as well as verbal communication. When social interaction becomes more important, some whose condition might have been overlooked suffer social and other exclusion and are more likely to have coexisting mental and physical conditions. Long-term problems include difficulties in daily living such as managing schedules, hypersensitivities, initiating and sustaining relationships, and maintaining jobs.
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.
The National Database for Autism Research (NDAR) is a secure research data repository promoting scientific data sharing and collaboration among autism spectrum disorder (ASD) investigators. The project was launched in 2006 as a joint effort between five institutes and centers at the National Institutes of Health (NIH): the National Institute of Mental Health (NIMH), the National Institute of Child Health and Human Development (NICHD), the National Institute of Neurological Disorders and Stroke (NINDS), the National Institute of Environmental Health Sciences (NIEHS), and the Center for Information Technology (CIT). The goal of NDAR is to provide a shared common platform for data collection, retrieval, and archiving to accelerate the advancement of research on autism spectrum disorders. The largest repository of its kind, NDAR makes available data at all levels of biological and behavioral organization for all data types. As of November 2013, data from over 90,000 research participants are available to qualified investigators through the NDAR portal. Summary information about the available data is accessible through the NDAR public website.
Discrimination against autistic people is the discrimination, persecution, and oppression that autistic people have been subjected to. Discrimination against autistic people is a form of ableism.
The Interagency Autism Coordinating Committee (IACC) is a United States federal advisory panel within the Department of Health and Human Services (HHS). It coordinates all efforts within HHS concerning autism spectrum disorder (ASD).
