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. [1]
Autism research conducted in Africa has been infrequent and unrepresentative of all African countries, making the prevalence of autism in Africa difficult to estimate. [2] Prevalence may be underestimated because reported cases are skewed toward more severe, and thus more recognizable, cases of autism. [3] In Africa, an autism diagnosis often co-occurs with epilepsy or intellectual disability. [3]
Possible reasons for the fact that many reported cases of autism in Africa are nonverbal cases include difficulty finding services even when a diagnosis is given. Educational and behavioral interventions for children with autism are largely unavailable, mental health care facilities are few, and there are too few facilities and personnel trained to work with autistic children in reference to the estimated number of autism cases in Africa.[ non-primary source needed ] [4] Bakare and Munir found that health care workers had low to average knowledge and awareness of autism spectrum disorder. In particular, psychiatric health care workers recognized symptoms of ASD better than pediatric health care workers, which implies that early recognition and intervention for children with autism in Africa is infrequent.[ non-primary source needed ] [4] Supernatural explanations of autism can influence treatment seeking by encouraging people to first seek help from spiritualists and traditional healers.[ non-primary source needed ] [4]
Studies have not elucidated the clinical presentation of autism in African nations. [5] Autism awareness is low, particularly in sub-Saharan Africa. Bakare and Munir suggest that education for the public and for health care workers is crucial for early diagnosis of ASD so that early intervention can be effective for African children. [3]
Autism was not recognized until the 1980s in China. The estimated prevalence of autism is 11.8 per 10,000 people while the estimated prevalence of autism spectrum conditions is 26.6 per 10,000 people. In Japan, recent estimates of autism spectrum are as high as 13 per 10,000 people. This suggests that autism is more common in Asia than previously thought.[ needs update ] [6] [7] The Childhood Autism Rating Scale (CARS), Clancy Autism Behavior Scale (CABS), Autism Behavior Checklist (ABC), and Checklist for Autism in Toddlers (CHAT) are frequently used as diagnostic instruments in China. [7] (see Autism in China)
In 2013, eight South Asian countries adopted a charter at the South Asian Autism Network's first meeting. The nations plan on working with each other's ministries, and SAAN is advocating long-term health care as well as intervention programs for people with autism. [8]
In certain areas, diagnosis and treatment of autism may be difficult because of the lack of facilities or physicians capable of autism recognition. Some families must travel for hours or days to reach an area in which diagnostic facilities are available. Stigma is also a salient issue. Families of children with autism in Hong Kong and China may experience stigmatization from others, which can lead to self-stigmatization in cultures where people focus on their social identity rather than their individual identity. This suggests that parents in China and Hong Kong may experience more stress from raising a child with autism than parents in other areas. Support from friends, families, and professionals is critical to enhance the psychological well-being of parents experiencing stigma. Autism may be of particular significance in India because of its characteristic abnormalities in social relationships, which may cause particular concern due to the value of social relatedness and conformity to social norms in India.[ medical citation needed ]
Questions about a potential cause of the Hikikomori phenomenon in Japan have been hypothesized. Because Hikikomori is similar to the social withdrawal exhibited by some people with autism spectrum disorders, some psychiatrists suggest that it may be related to autism spectrum disorders and other disorders that may affect social integration, but that their disorders are altered from their typical Western presentation because of Japanese sociocultural pressures. [9]
As recently as 1984, researchers questioned whether autism was a universal phenomenon. Some scientists believed that autism was a condition limited to Western and technologically developed nations; however, now there is evidence of increased prevalence of and knowledge about ASD cross-culturally and internationally. [3] Although autism has a biological basis and there are clear criteria for an autism diagnosis, its symptoms may be viewed differently across cultures. These differences may extend to the perception of autism in different cultures and perceptions of the most effective treatment options. [10] [11]
The median prevalence rate of autism spectrum disorders in Europe is 59 per 10,000 people, while the median prevalence estimated in North America is 86 per 10,000. [12] In western nations, children who show developmental problems are referred for evaluation by a pediatrician. Preliminary screening instruments include the Modified Checklist for Autism in Toddlers (M-CHAT), Social Communication Questionnaire (SCQ), and Autism Spectrum Screening Questionnaire (ASSQ). [13] Autism spectrum evaluations are typically conducted by professionals who specialize in developmental disorders, such as psychologists, psychiatrists, or neurologists. [13] Diagnostic instruments that assessing clinicians may use include the Autism Diagnostic Interview-Revised, Autism Diagnostic Observation Schedule, and Childhood Autism Rating Scale, as well as clinical judgment using criteria from the Diagnostic and Statistical Manual. [14]
Behavioral intervention and medications are frequently used to manage the symptoms of autism. Early intervention programs can improve cognitive and language skills in children who have been diagnosed with autism spectrum disorder. [13] Behavioral interventions include Applied Behavioral Analysis, Developmental, Individual Difference, Relationship-based (DIR)/Floortime Model, and Treatment and Education of Autistic and Related Communication Handicapped Children (TEACCH). [13]
There are no medications that have been approved to treat autism spectrum disorder, but some medications may be prescribed off-label to treat symptoms of ASD. [13] Antipsychotic medications may be used to reduce irritability and aggression in children with autism. Stimulant medications are used to treat symptoms of hyperactivity and inattentiveness. Antidepressant medications are occasionally prescribed to reduce the restricted and repetitive behaviors associated with autism. [13] More research is needed to determine if the safety and effectiveness of medications. [15]
The estimated lifetime cost of caring for an individual with autism as of 2013 is between $1.4 million and $2.4 million, using data from the United Kingdom and the United States. [16] While some of these costs are incurred for diagnosis and treatment costs, the problem is exacerbated by reduced family earnings when a family member may forgo working in order to care for a family member with autism. [16]
Researchers who aim to obtain reliable data about autism around the world are challenged by many factors. Awareness about autism differs from nation to nation. Services for people with autism and their families differs in availability. The behavior of people with autism may differ cross-culturally, and the capacity to do autism research can be impeded because of these differences. [1] [11] A further challenge is that caregivers and professionals must have knowledge that certain symptoms are associated with autism, and they must perceive these symptoms as problematic. In a certain culture, for example, if language delays are not seen as uncommon until a child is four or five, a professional may not see the delay as symptomatic of autism.[ medical citation needed ] In some nations, such as South Korea, the stigma surrounding autism is so high that families may avoid getting their child tested for autism even when the child has noticeable developmental delays. [1]
Elsabbagh and colleagues (2012) cite multiple challenges for researchers, including lack of funding for research. The 10/90 gap means that only 10 percent of global spending on health goes toward funding for problems that affect the poorest 90 percent of the world. [5] They also discuss the lack of accessibility or availability of autism services, the expensive cost of resources for epidemiological studies, and variation in diagnosis because clinical judgment is often used for diagnosis. [5]
Autism research is further complicated by the fact that families often have different perceptions of autism's etiology. Beliefs include the child being a product of witchcraft or parental misdeed or sin. Positive appraisals include parents' beliefs that the child is a blessing to show that the parents are worthy of taking care of such a child. Negative appraisals of what autism means and its etiology can cause increased stress in families of children with autism.[ medical citation needed ]
An autistic culture has emerged, accompanied by a number of movements and events that encourage greater tolerance of those with autism. Prominent movements include the autistic rights movement and neurodiversity movement which seek to promote the idea that autism is a difference rather than a disease. [17] [18] Events include World Autism Awareness Day, Autism Sunday, Autistic Pride Day, Autreat, and others. [19] [20] [21] [22]
The autism rights movement, also known as the autistic culture movement or the neurodiversity movement, is a social movement within the context of disability rights that emphasizes the concept of neurodiversity, viewing the autism spectrum as a result of natural variations in the human brain rather than a disorder to be cured. [23] The autism rights movement advocates a variety of goals, including greater acceptance of autistic behaviors; [24] therapies that focus on coping skills rather than imitating the behaviors of neurotypical peers; [25] the creation of social networks and events that allow autistic people to socialize on their own terms; [26] and the recognition of the autistic community as a minority group. [27]
Autism rights or neurodiversity advocates believe that the autism spectrum should be accepted as a natural expression of the human genome.[ citation needed ] This perspective is distinct from two other likewise distinct views: the medical perspective, that autism is caused by a genetic defect and should be addressed by targeting the autism gene(s), and fringe theories that autism is caused by environmental factors such as vaccines. [23]
The movement is controversial in autism advocacy and research groups. A common criticism leveled against autistic activists is that the majority of them are "high-functioning" or have Asperger syndrome and do not represent the views of "low-functioning" autistic people and does not represent the wishes of autism community as a whole. With certain individuals emphasizing their desire to be treated. [28]
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.
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).
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.
The following outline is provided as an overview of and topical guide to autism:
The Autism Diagnostic Observation Schedule (ADOS) is a standardized diagnostic test for assessing autism spectrum disorder. The protocol consists of a series of structured and semi-structured tasks that involve social interaction between the examiner and the person under assessment. The examiner observes and identifies aspects of the subject's behavior, assigns these to predetermined categories, and combines these categorized observations to produce quantitative scores for analysis. Research-determined cut-offs identify the potential diagnosis of autism spectrum disorder, allowing a standardized assessment of autistic symptoms.
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.
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 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.
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.
Sex and gender differences in autism exist regarding prevalence, presentation, and diagnosis.
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 sexual orientation, gender dysphoria and autism. Alternatively, autistic people may be less reliant on social norms and thus are 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 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.
