The most recentĮstimates of intellectual ability among youth with ASD suggest that approximately 31 per cent also have an intellectual disability, 25 per cent have low levels of cognitive functioning Andīecause the DSM-5 classifies autism on a spectrum of wide variation in skills, it also includes specifiers such as “with or without accompanying intellectual impairment” and severity level to better address the needs for support. The communication and behavioural difficulties vary widely in severity and developmental course, resulting in great diversity in how ASD presents in each individual.įor example, language impairment, which has been linked to autism disorder diagnosis in the past, is now classified as a co-occurring condition, since a wide variation in language is seen among individuals on different ends of the autism spectrum. Though these symptoms appear in the first few years of life, they can often go unnoticed until later in life when demands upon the child increase - for instance, upon entry into school. Responses to sensory stimulation (e.g., touch and tactile sensations). In addition, 45–90 per cent of children with ASD have sensory sensitivity, such as avoidance of sensory stimuli (e.g., noise) and more extreme (lower or higher) Interaction, as well as restricted, repetitive patterns of behaviour, interests or activities. The DSM-5 defines autism spectrum disorder as a set of atypical neurodevelopmental conditions (as opposed to the “neurotypical” conditions present in the general population) characterized by persistent impairment in social communication and In the DSM-IV (impairments in social interaction impairments in communication and restricted, repetitive, and stereotyped behaviour, interests and activities), to two in the fifth edition. With this change, there was also a shift from three diagnostic criteria The fifth edition of the DSM (published in 2013), made significant changes to the diagnostic criteria of autism, adopting the umbrella term autism spectrum disorder to describe three previously separate disorders: autistic disorder (also referred to as classic autism) Īsperger syndrome (also known as Asperger’s syndrome or simply Asperger’s) and pervasive developmental disorder not otherwise specified (PDD-NOS, also referred to as atypical autism). The concept of autism has evolved over the subsequent decades, with its changing criteria outlined in the different editions of the DSM and the World Health Organization’s International Classification of Diseases. This was an important shift in conceiving autism as a developmental, rather than psychotic, disorder.

In North America when it was included in the American Psychiatric Association’s Diagnostic and Statistical Manual of Mental Disorders, 3rd Edition ( DSM-III) under a form of childhood onset disorders called pervasive developmental disorders Finally, in 1980, autism became an officially recognized diagnosis More than 20 years later, despite these efforts to define autism, infantile autism was first incorporated into an international diagnostic classification system as a subtype of schizophrenia. Interactions driven by feelings) present by 24 months of age, and (2) elaborate, repetitive routines with intense resistance to change.

In 1956, Leo Kanner and a colleague, Leon Eisenberg, proposed two essential criteria for the diagnosis of infantile autism: (1) a profound lack of affective contact (i.e., In 1944, Austrian pediatrician Hans Asperger also described behaviours in children who showed inappropriate social interactions but had good language skills, which they used to talk only about a narrow range of topics of interest to them.įor over a decade, autism remained poorly understood and its concept was disputed. This assertion remained highlyĬontentious for years and was eventually discredited. That early infantile autism may be genetic in origin, he also noted that unaffectionate, detached and obsessive parents may be to blame for the condition. Kanner suggested that infantile autism differed from schizophrenia because of its early onset. However, it was not until 1943 that Austrian-American psychiatrist Leo Kanner recognized autism as a separate disorder with a pattern of behaviours that he called “early infantileĪutism.” He described individuals with autism as having difficulties with social interaction and communication and a great resistance to change. History of Autism Spectrum Disorder: Evolving ConceptsĪutism as a concept first emerged in 1911, when Swiss psychiatrist Eugen Bleuler coined this term to refer to particular behaviours (e.g., detachment from others) that he observed in adults with schizophrenia.
