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 by relatively unimpaired spoken language and intelligence.
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.
Neurodiversity is a framework for understanding human brain function and mental illness. It argues that diversity in human cognition is normal and that some conditions classified as mental disorders 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 neurotypical (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.
Ole Ivar Løvaas was a Norwegian-American clinical psychologist and professor at the University of California, Los Angeles. He is most well known for his research on what is now called applied behavior analysis (ABA) to teach autistic children through prompts, modeling, and positive reinforcement. The therapy is also noted for its use of aversives (punishment) to reduce undesired behavior, however these are now used less commonly than in the past.
Mind-blindness, mindblindness or mind blindness is a theory initially proposed in 1990 that claims that all autistic people have a lack or developmental delay of theory of mind (ToM), meaning they are unable to attribute mental states to others. According to the theory, a lack of ToM is considered equivalent to a lack of both cognitive and affective empathy. In the context of the theory, mind-blindness implies being unable to predict behavior and attribute mental states including beliefs, desires, emotions, or intentions of other people. The mind-blindness theory asserts that children who delay in this development will often develop autism.
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.
Self-stimulatory behavior, also known as "stimming" and self-stimulation, is the repetition of physical movements, sounds, words, moving objects, or other repetitive behaviors. Such behaviors are found to some degree in all people, especially those with developmental disabilities such as ADHD, and are also frequent in people on the autism spectrum. People diagnosed with sensory processing disorder are also known to potentially exhibit stimming behaviors.
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.
Asociality refers to the lack of motivation to engage in social interaction, or a preference for solitary activities. Asociality may be associated with avolition, but it can, moreover, be a manifestation of limited opportunities for social relationships. Developmental psychologists use the synonyms nonsocial, unsocial, and social uninterest. Asociality is distinct from, but not mutually exclusive to, anti-social behavior. A degree of asociality is routinely observed in introverts, while extreme asociality is observed in people with a variety of clinical conditions.
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 difficulty 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-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.
Diagnosis, treatment, and experiences of autism varies globally. Although the diagnosis of autism is rising in post-industrial nations, diagnosis rates are much lower in developing nations.
Sex and gender differences in autism exist regarding prevalence, presentation, and diagnosis.
Marian Diamond Sigman (1941–2012) was a developmental and child clinical psychologist known for her research on autism spectrum disorder (ASD). At the time of her death, she was Professor Emeritus of Psychiatry and Biobehavioral Sciences and Psychology at the University of California, Los Angeles (UCLA).
Autistic masking, also referred to as camouflaging or neurodivergent masking, is the conscious or subconscious suppression of autistic behaviors and compensation of difficulties in social interaction by autistic people with the goal of being perceived as neurotypical. Masking is a learned coping strategy that can be successful from the perspective of autistic people, but can also lead to adverse mental health outcomes.
Current research indicates that autistic people have higher rates of LGBT identities and feelings than the general population. A variety of explanations for this have been proposed, such as prenatal hormonal exposure, which has been linked with both sexual orientation, gender dysphoria and autism. Alternatively, autistic people may be less reliant on social norms and thus more open about their orientation or gender identity. A narrative review published in 2016 stated that while various hypotheses have been proposed for an association between autism and gender dysphoria, they lack strong evidence.
The theory of the double empathy problem is a psychological and sociological theory first coined in 2012 by Damian Milton, an autistic autism researcher. This theory proposes that many of the difficulties autistic individuals face when socializing with non-autistic individuals are due, in part, to a lack of mutual understanding between the two groups, meaning that most autistic people struggle to understand and empathize with non-autistic people, whereas most non-autistic people also struggle to understand and empathize with autistic people. This lack of understanding may stem from bidirectional differences in communication style, social-cognitive characteristics, and experiences between autistic and non-autistic individuals, but not necessarily an inherent deficiency. Recent studies have shown that most autistic individuals are able to socialize, communicate effectively, empathize well, and display social reciprocity with most other autistic individuals. This theory and subsequent findings challenge the commonly held belief that the social skills of autistic individuals are inherently impaired, as well as the theory of "mind-blindness" proposed by prominent autism researcher Simon Baron-Cohen in the mid-1980s, which suggested that empathy and theory of mind are universally impaired in autistic individuals.
The diagnosis of autism is based on a person's reported and directly observed behavior. There are no known biomarkers for autism spectrum conditions that allow for a conclusive diagnosis.
