  • The latest prevalence studies of autism indicate that 1.1% of the population in the UK may have autism. This means that over 695,000 people in the UK may have autism, an estimate derived from the 1.1% prevalence rate applied to the 2011 UK census figures.
  • Emerson and Baines (2010) in their meta-analysis of prevalence studies found a range of people with learning disabilities and autism from 15% to 84%, with a mean of 52.6%.
  • Around a third of people with a learning disability may also have autism.
  • ...19 more annotations...
  • The NHS Information Centre, Community and Mental Health Team, Brugha et al.(2012), found between 31% and 35.4% of people with a learning disability have autism.
  • Baird et al (2006) found a male to female ratio of 3.3:1 for the whole spectrum in their sample.  The Adult Psychiatric Morbidity Survey looked at people in private households, and found a prevalence rate of 1.8% male compared with 0.2% female, (Brugha et al, 2009). However, when they extended the study to include those people with learning disabilities who had been unable to take part in the APMS in 2007 and those in communal residential settings, they found that the rates for females were much closer to those of the males in the learning disabled population, (The NHS Information Centre, Community and Mental Health Team, Brugha et al., 2012).
  • For over 30 years, Sula Wolff, in Edinburgh, has studied children of average or high ability who are impaired in their social interaction but who do not have the full picture of the triad of impairments
  • more than 50 years since Leo Kanner first described his classic autistic syndrome
  • The specific pattern of abnormal behaviour first described by Leo Kanner is also known as 'early infantile autism'. Kanner made no estimate of the possible numbers of people with this condition but he thought that it was rare (Kanner, 1943).
  • autism spectrum disorders are under-diagnosed in females, and therefore the male to female ratio of those who have autism may be closer than is indicated by the figure of 5:1. The under recognition of autism spectrum disorders in females is discussed in Gould and Ashton-Smith (2011)
  • the clinical picture overlaps with Asperger syndrome to a large extent. However, these children represent the most subtle and most able end of the autism spectrum. The majority become independent as adults, many marry and some display exceptional gifts, though retaining the unusual quality of their social interactions
  • they often have a difficult time at school and they need recognition, understanding and acceptance from their parents and teachers. The approach that suits them best is the same as that which is recommended for children with Asperger syndrome and high-functioning autism.

      http://www.autism.org.uk/about-autism/myths-facts-and-statistics/statistics-how-many-people-have-autism-spectrum-disorders.aspx The word 'autism' was first used by Leo Kanner in the term 'early infantile autism' which was used to describe a specific pattern of abnormal behaviour. 
  • The Autism and Developmental Disabilities Monitoring Network in the USA looked at 8 year old children in 14 states in 2008, and found a prevalence rate of autism spectrum disorders within those states overall of  1 in 88, with around five times as many boys as girls affected (Autism and Developmental Disabilities Monitoring Network Surveillance Year 2008 Principal Investigators, 2012).
  • The National Center for Health Statistics in the USA published findings from telephone surveys of parents of children aged 6-17 undertaken in 2011-12. The report showed a prevalence rate for ASD of 1 in 50, (Blumberg, S .J. et al, 2013).
  • 2.64% was found in a study done in South Korea, where the researchers found two thirds of the ASD cases were in the mainstream school population, and had never been diagnosed before., (Kim et al, 2011).
  • both the increase in estimates over time and the variability between countries and regions are likely to be because of broadening diagnostic criteria, diagnostic switching, service availability and awareness of ASD among professionals and the public, (Elsabbagh M. et al, 2012).
  • The Department of Health then funded a project to build on the APMS study and look more closely at the numbers of adults with autism that could not have been included in the original study. This included people in residential care settings and those with a more severe learning disability. The study was led by Professor Terry Brugha of the University of Leicester, who also led on autism research for the APMS 2007.  Combining its findings with the original APMS, it found that the actual prevalence of autism is approximately 1.1% of the English population, (The NHS Information Centre, Community and Mental Health Team, Brugha, T. et al., 2012)

  • Autistic Spectrum Disorder (ASD) is a term used to describe a number of symptoms and behaviours which affect the way in which a group of people understand and react to the world around them. It's an umbrella term which includes autism, Asperger syndrome and pervasive developmental disorders. All of these autistic spectrum disorders have an onset before the age of three
  • Recent research by the Learning Disabilities Observatory indicates that around 20-30% of people with learning disabilities have an ASD.
  • Being diagnosed with Asperger syndrome does not constitute having a learning disability.
  • ...6 more annotations...
  • All children and adults with an ASD will have the following core symptoms in what is known as the ‘triad’ of impairments:
  • 1. Non-verbal and verbal communication People with an ASD have difficulty in understanding the communication and language of others, and in communicating themselves. Many children are delayed in learning to speak and a small minority do not develop much functional speech. This does not mean they cannot communicate, as they use other methods to communicate their needs. People with an ASD tend to have a literal understanding of language, so the use of metaphors such as ‘it’s raining cats and dogs’ should be avoided.
  • 2. Social understanding and social behaviour People with an ASD have difficulty understanding the social behaviour of others and can behave in socially inappropriate ways. People with an ASD have difficulty empathising with others, and as a result are unable to read social contexts. Children with an ASD often find it hard to play and communicate with other children, because of their difficulties with empathy.

      60-70% of ppl with ASD will have LD 20-30% of ppl with LD also have ASD
  • 3. Imagining and thinking/behaving flexibly Children with an ASD find it difficult to engage in imaginative play, so they tend to spend more time in solitary play. Children with an ASD can have an excellent memory concerning toys or activities they are passionate about. People with an ASD tend to have particular interests in specific topics or activities, which they may pursue obsessively. People with an ASD often find change difficult to cope with, and have a preference for routine. They may also struggle to transfer skills to other activities.
  • Approximately 1% of the population has an autistic spectrum condition. The prevalence rate of autistic spectrum conditions is higher in men than it is in women (1.8% vs. 0.2%). 60-70% of people who have an autistic spectrum condition will also have a learning disability.

  • investigators compared autism prevalence using DSM-IV and DSM-5 criteria for ASD. They also re-evaluated school children previously diagnosed with ASD for the newly created diagnosis of social communication disorder (SCD).
  • the estimated prevalence of autism under the new DSM-5 criteria would decrease only to the extent that some children would receive the new diagnosis of social communication disorder (SCD)
  • 83 percent of children who received a diagnosis of autism under the DSM-IV would still receive the diagnosis under DSM-5

  • Recalling the Convention on the Rights of the Child and the Convention on the Rights of Persons with Disabilities as well as resolutions adopted by other forums, in particular the United Nations General Assembly on autism
  • Reiterating the provisions of Constitutions of our respective countries safeguarding against discrimination and social exclusion of people on grounds of any disability or condition, and securing the provision of the basic necessities of life, in particular education and medical care, and the right to social security to public assistance in cases of undeserved want arising from illness and disabilities,
  • Noting that developmental disorders are being increasingly recognized all over the world as disabling conditions which seriously influence everyday functioning of affected children, severely interfere with their developmental, educational and social attainments, and bring significant economic costs to families and societies
  • ...21 more annotations...
  • Aware that autism is a lifelong developmental disability that affects the functioning of the brain, and characterised by impairments in social interaction, problems with verbal and non-verbal communication and restricted, repetitive behaviour, interests and activities,
  • Concerned that, despite increasing evidence documenting the effectiveness of early interventions in improving the overall functioning of the child and long-term outcomes, children and families in need often have poor access to services and do not receive adequate treatment and care
  • Deeply concerned at the prevalence and high rate of autism in all societies and regions and its consequent developmental challenges to long-term health care, education and training as well as its tremendous impact on communities and societies
  • Recalling that children with developmental disorders and their families often face major challenges associated with stigma, isolation and discrimination as well as a lack of access to health care and education facilities
  • Recalling further that even the basic human rights of children and adults with developmental disorders are often abused, in many cases in flagrant violation of existing UN declarations and treaties
  • Recognising the public health importance to address mental and developmental disorders and autism in children, based on their prevalence, disability burden, long-term health consequences and the associated human rights violations
  • Recognising further that attention received by policy makers and public health experts and consequent allocation of resources have so far been inadequate to address the treatment gap for developmental disorders, and stronger concerted efforts are required
  • Acknowledging efforts undertaken by governments and international global health actors to tackle the problem, including the commemoration of the UN World Autism Awareness Day, which led to increased international public concerns for autism and other developmental disorders
  • Inspired further by a vision that all individuals with autism and developmental disorders ought to receive adequate and equal opportunities to enjoy health, achieve their optimal developmental potential and quality of life, and participate in society

  • Federal Register, vol. 71, no. 156, 2006, Rules and Regulations, p. 46756 a, 2006.
  • examined the definition of autism published by state education agencies (SEAs), as well as SEA-indicated evaluation procedures for determining student qualification for autism
  • compared components of each SEA definition to aspects of autism from two authoritative sources: Diagnostic and Statistical Manual of Mental Disorders (DSM-IV-TR) and Individuals with Disabilities Education Improvement Act (IDEA-2004)
  • ...10 more annotations...
  • also compared SEA-indicated evaluation procedures across SEAs to evaluation procedures noted in IDEA-2004
  • many more SEA definitions incorporate IDEA-2004 features than DSM-IV-TR features. However, despite similar foundations, SEA definitions of autism displayed considerable variability
  • The federal definition of autism preceded the fourth edition of the Diagnostic and Statistical Manual (DSM-IV) [8], and it is essentially unchanged since 1990.
  • The federal definition is generally compatible with both the category of Pervasive Developmental Disorder (PDD) as described in DSM-IV and Autism Spectrum Disorder as described in DSM-5 [9], but it does not match any specific variety of PDD (see below). Within public school systems, students who have been clinically diagnosed with either a DSM-IV PDD or with DSM-5 Autism Spectrum Disorder are likely to be identified under the federal category of autism for the purpose of receiving special education services
  • In contrast to the IDEA-2004 definition, criteria for autism are more specific in the DSM-IV clinical diagnostic criteria
  • DSM-IV was superseded by DSM-5 [9]. The disorders comprising PDD in DSM-IV are largely addressed in DSM-5 by the Autism Spectrum Disorders category, which—unlike DSM-IV’s PDD—has no subcategories.
  • identification criteria still include substantial social problems (social initiations and responses, nonverbal social communication, and social relationships) and restricted, repetitive behaviors or interests (deviant speech or movements, rituals and resistance to change, preoccupations, and sensory reactivity). State education agencies (SEAs) have not yet incorporated DSM-5 information into their policies, procedures, and practices related to students with autism, and the DSM-5 definition was not involved in the present study.
  • State education agency (SEA) definitions of a disability do not have to match the federal definition but must substantially address its elements or lose federal financial support for special education.
  • No doubt the prevalence of ASD naturally varies somewhat with geography [4] but probably not by such a large factor, greater than tenfold in adjacent states. Conceivably, some state-by-state variation might be attributable to the content of SEA definitions of autism and perhaps the evaluation procedures required to accurately measure the concepts presented in definitions.
  • In a study of SEA definitions of autism, MacFarlane and Kanaya [10] found substantial variation in the eligibility criteria used by different states. By their analysis, 35% of SEAs based autism eligibility solely on the federal definition of autism, while 65% used diverse other criteria including symptoms of autism from the DSM-IV-TR
