Intellectual functioning

Last updated

Intellectual functioning refers to the "general mental ability that includes reasoning, planning, problem solving, abstract thinking, comprehending complex ideas, learning quickly and learning from experience". Significantly limited or impaired intellectual functioning characterizes intellectual disabilities. [1] [2]

Ageing has been shown to cause a decline in intellectual functioning. [3]

High-functioning autism (HFA) was historically an autism classification to describe a person who exhibited no intellectual disability but otherwise showed autistic traits, such as difficulty in social interaction and communication, as well as repetitive, restricted patterns of behavior. The term is often applied to autistic people who are fluently verbal and of at least average intelligence. However, many in medical and autistic communities have called to stop using the term, finding it simplistic and unindicative of the difficulties some autistic people face.

Developmental disability is a diverse group of chronic conditions, comprising mental or physical impairments that arise before adulthood. Developmental disabilities cause individuals living with them many difficulties in certain areas of life, especially in "language, mobility, learning, self-help, and independent living". Developmental disabilities can be detected early on and persist throughout an individual's lifespan. Developmental disability that affects all areas of a child's development is sometimes referred to as global developmental delay.

Specific developmental disorders (SDD) was a classification of disorders characterized by delayed development in one specific area or areas. Specific developmental disorders were contrasted to pervasive developmental disorders which were characterized by delays in the development of multiple basic functions including socialization and communication.

Neurodevelopmental disorders are a group of mental conditions affecting the development of the nervous system, which includes the brain and spinal cord. According to the American Psychiatric Association Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, (DSM-5) published in 2013, these conditions generally appear in early childhood, usually before children start school, and can persist into adulthood. The key characteristic of all these disorders is that they negatively impact a person's functioning in one or more domains of life depending on the disorder and deficits it has caused. All of these disorders and their levels of impairment exist on a spectrum, and affected individuals can experience varying degrees of symptoms and deficits, despite having the same diagnosis.

"The normalization principle means making available to all people with disabilities patterns of life and conditions of everyday living which are as close as possible to the regular circumstances and ways of life or society." Normalization is a rigorous theory of human services that can be applied to disability services. Normalization theory arose in the early 1970s, towards the end of the institutionalisation period in the US; it is one of the strongest and long lasting integration theories for people with severe disabilities.

The American Association on Intellectual and Developmental Disabilities (AAIDD) is an American non-profit organization focusing on intellectual disability and related developmental disabilities. AAIDD has members in the United States and more than 50 other countries.

Supported living or supportive living refers to a range of services and community living arrangements (CLAs) designed with individuals with disabilities and their families to support citizens with disabilities to attain or retain their independence or interdependence in their local communities. Supported living is recorded in the history of the NASDDDS, celebrating its 50th anniversary. Community Supported Living Arrangements (CSLA) was a landmark federal multi-state demonstration to illustrate the federal role in community living in the US. Supported living is considered a core service or program of community living programs funded through federal-state-local partnerships.

A group home, congregate living facility, care home, adult family home, etc., is a structured and supervised residence model that provides assisted living and medical care for those with complex health needs. Traditionally, the model has been used for children or young people who cannot live with their families or afford their own homes, people with chronic disabilities who may be adults or seniors, or people with dementia and related aged illnesses. Typically, there are no more than six residents, and there is at least one trained caregiver there 24 hours a day. In some early "model programs", a house manager, night manager, weekend activity coordinator, and four part-time skill teachers were reported. Originally, the term group home referred to homes of 8 to 16 individuals, which was a state-mandated size during deinstitutionalization. Residential nursing facilities, also included in this article, may be as large as 100 individuals in 2015, which is no longer the case in fields such as intellectual and developmental disabilities. Depending on the severity of the condition requiring one to need to live in a group home, some clients are able to attend day programs and most clients are able to live normal lifestyles.

<span class="mw-page-title-main">Learning disability</span> Range of neurodevelopmental conditions

Learning disability, learning disorder, or learning difficulty is a condition in the brain that causes difficulties comprehending or processing information and can be caused by several different factors. Given the "difficulty learning in a typical manner", this does not exclude the ability to learn in a different manner. Therefore, some people can be more accurately described as having a "learning difference", thus avoiding any misconception of being disabled with a possible lack of an ability to learn and possible negative stereotyping. In the United Kingdom, the term "learning disability" generally refers to an intellectual disability, while conditions such as dyslexia and dyspraxia are usually referred to as "learning difficulties".

<span class="mw-page-title-main">Intellectual disability</span> Generalized neurodevelopmental disorder

Intellectual disability (ID), also known as general learning disability, and formerly mental retardation, is a generalized neurodevelopmental disorder characterized by significant impairment in intellectual and adaptive functioning that is first apparent during childhood. Children with intellectual disabilities typically have an intelligence quotient (IQ) below 70 and deficits in at least two adaptive behaviors that affect everyday living. According to the DSM-5, intellectual functions include reasoning, problem solving, planning, abstract thinking, judgment, academic learning, and learning from experience. Deficits in these functions must be confirmed by clinical evaluation and individualized standard IQ testing. On the other hand, adaptive behaviors include the social, developmental, and practical skills people learn to perform tasks in their everyday lives. Deficits in adaptive functioning often compromise an individual's independence and ability to meet their social responsibility.

Mental disorders diagnosed in childhood can be neurodevelopmental, emotional, or behavioral disorders. These disorders negatively impact the mental and social wellbeing of a child, and children with these disorders require support from their families and schools. Childhood mental disorders often persist into adulthood. These disorders are usually first diagnosed in infancy, childhood, or adolescence, as laid out in the DSM-5 and in the ICD-11.

Research published from 2000 to 2020 illustrates increased prevalence rates of sexual violence against people with intellectual disabilities, compared to the general population.:61 The World Health Organization (WHO) funded a study which concluded that 15% of the adult population worldwide in 2012 had a disability, putting them at increased risk of physical, sexual, and intimate partner violence. Of that 15%, 6.1% had intellectual disability with 5.5% experiencing sexual violence. In another 2012 report, the WHO found that worldwide, children with intellectual disabilities experienced a 4.6 times greater risk of sexual violence than those without disability.

There are a variety of disabilities affecting cognitive ability. This is a broad concept encompassing various intellectual or cognitive deficits, including intellectual disability, deficits too mild to properly qualify as intellectual disability, various specific conditions, and problems acquired later in life through acquired brain injuries or neurodegenerative diseases like dementia.

Michael Lee Wehmeyer is Distinguished Professor Emeritus in and former chairperson of the Department of Special Education at the University of Kansas. His research focused on self-determination and self-determined learning, the application of positive psychology and strengths-based approaches to disability, and the education of students with intellectual or developmental disabilities. He is past Director and Senior Scientist at Kansas University's Beach Center on Disability. He also formerly directed the Kansas University Center on Developmental Disabilities.

Family support is the support of families with a member with a disability, which may include a child, an adult, or even the parent in the family. In the United States, family support includes "unpaid" or "informal" support by neighbors, families, and friends, "paid services" through specialist agencies providing an array of services termed "family support services", school or parent services for special needs such as respite care, specialized child care or peer companions, or cash subsidies, tax deductions or other financial subsidies. Family support has been extended to different population groups in the US and worldwide. Family support services are currently a "community services and funding" stream in New York and the US which has had variable "application" based on disability groups, administrating agencies, and even, regulatory and legislative intent.

Gunnar Dybwad (1909–2001) was an American professor and advocate for the rights of people with disabilities, particularly developmental disabilities. He is best known for his support for the social model of disability, reframing disability accommodations as a matter of civil rights, not medical treatment. The American Association on Intellectual and Developmental Disabilities gives out the Dybwad Humanitarian Award annually in his honor.

For many elderly carers of a relative who has a learning or other disability, future planning is an issue. The population of older parents who have children with a learning disability is growing and many of their children are likely to outlive them. In many cases the caring role can span up to seven decades, ending only with their death. Governments and other service providers cannot ignore the pressing needs of this population and their parent and sibling carers. In most countries, family carers provide inexpensive care for a person with a learning disability and other disabilities. This trend is set to continue in England. Demographic changes and the health needs of these two growing populations must be considered against government policy constraints and limited in-home and external care options in order to avoid a crisis. The consequences of not supporting these family carers will lead to crisis management, increase in distress and care giving burdens, and increased spending on unsuitable crisis placements. Housing and financial guidance are issues for caregivers.

Hall v. Florida, 572 U.S. 701 (2014), was a United States Supreme Court case in which the Court held that a bright-line IQ threshold requirement for determining whether someone has an intellectual disability is unconstitutional in deciding whether they are eligible for the death penalty.
