Developmental disability is a diverse group of chronic conditions that are due to 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".Center for Disease Control and Prevention.

Causes

The causes of developmental disabilities are varied and remain unknown in a large proportion of cases. Even in cases of known etiology the line between "cause" and "effect" is not always clear, leading to difficulty in categorizing causes. Genetic factors have long been implicated in the causation of developmental disabilities. There is also a large environmental component to these conditions, and the relative contributions of
nature versus nurture The nature versus nurture debate involves whether human behavior is determined by the environment, either prenatal or during a person's life, or by a person's genes. The alliterative expression "nature and nurture" in English has been in use since ...

Preterm birth
is known to be a predictor for potential developmental disabilities later in childhood, which further complicates the question of nature versus nurture, as Current theories on causation focus on genetic factors, and over 1,000 known genetic conditions include developmental disabilities as a symptom. Developmental disabilities affect between 1 and 2% of the population in most western countries, although many government sources acknowledge that statistics are flawed in this area. The worldwide proportion of people with developmental disabilities is believed to be approximately 1.4%. It is twice as common in males as in females, and some researchers have found that the prevalence of mild developmental disabilities is likely to be higher in areas of poverty and deprivation, and among people of certain ethnicities.

Associated issues


Physical health issues

There are many physical health factors associated with developmental disabilities. For some specific syndromes and diagnoses, these are inherent, such as poor heart function in people with Down syndrome. People with severe communication difficulties find it difficult to articulate their health needs, and without adequate support and education might not recognize ill health.

With consistent visits to health care providers more people with developmental disabilities are likely to receive appropriate treatment than the general population that is not required to visit various health care providers. These problems are exacerbated by difficulties in diagnosis of mental health issues, and in appropriate treatment and medication, as for physical health issues.

Failings in care have been identified in one in eight deaths of people with learning difficulties under NHS England.


Challenging behavior

Some people with developmental disabilities (particularly Autism) exhibit challenging behavior, defined as "culturally abnormal behaviour(s) of such intensity, frequency or duration that the physical safety of the person or others is placed in serious jeopardy, or behaviour which is likely to seriously limit or deny access to the use of ordinary community facilities". Common types of challenging behavior include self-injurious behavior (such as hitting, headbutting, biting), aggressive behavior (such as hitting others, shouting, screaming, spitting, kicking, swearing, hairpulling), inappropriate sexualized behavior (such as public masturbation or groping), behavior directed at property (such as throwing objects and stealing) and stereotyped behaviors (such as repetitive rocking, [[echolalia or elective incontinence). Such behaviors can be assessed to suggest areas of further improvement, using assessment tools such as the [[Nisonger Child Behavior Rating Form (NCBRF). Challenging behavior in people with developmental disabilities may be caused by a number of factors, including biological (pain, medication, the need for sensory stimulation), social (boredom, seeking social interaction, the need for an element of control, lack of knowledge of community norms, insensitivity of staff and services to the person's wishes and needs), environmental (physical aspects such as noise and lighting, or gaining access to preferred objects or activities), psychological (feeling excluded, lonely, devalued, labelled, disempowered, living up to people's negative expectations) or simply a means of communication. A lot of the time, challenging behavior is learned and brings rewards and it is very often possible to teach people new behaviors to achieve the same aims. Challenging behavior in people with developmental disabilities can often be associated with specific mental health problems. Experience and research suggests that what professionals call "challenging behavior" is often a reaction to the challenging environments that those providing services create around people with developmental disabilities. "Challenging behavior" in this context is a method of communicating dissatisfaction with the failure of those providing services to focus on what kind of life makes most sense to the person, and is often the only recourse a developmentally disabled person has against unsatisfactory services or treatment and the lack of opportunities made available to the person. This is especially the case where the services deliver lifestyles and ways of working that are centered on what suits the service provider and its staff, rather than what best suits the person. In general, behavioral interventions or what has been termed [[applied behavior analysis has been found to be effective in reducing specific challenging behavior. Recently, efforts have been placed on developing a developmental pathway model in the behavior analysis literature to prevent challenging behavior from occurring. This method is controversial according to the [[Autistic Self Advocacy Network, saying that this type of therapy can lead to the development of [[Post-traumatic stress disorder|Post Traumatic Stress Disorder and worsening of symptoms later in life.


Societal attitudes

Throughout history, people with developmental disabilities have been viewed as incapable and incompetent in their capacity for decision-making and development. Until the [[Age of Enlightenment|Enlightenment in Europe, care and asylum was provided by families and the Church (in monasteries and other religious communities), focusing on the provision of [[Maslow's hierarchy|basic physical needs such as food, shelter and clothing. Stereotypes such as the dimwitted [[village idiot, and potentially harmful characterizations (such as [[demonic possession for people with epilepsy) were prominent in social attitudes of the time. Early in the twentieth century, the [[eugenics movement became popular throughout the world. This led to the [[forced sterilization and prohibition of [[marriage for the developmentally disabled in most of the developed world and was later used by [[Hitler as rationale for the mass murder of mentally challenged individuals during the [[Holocaust. The eugenics movement was later thought to be seriously flawed and in violation of human rights and the practice of forced sterilization and prohibition from marriage was discontinued by most of the developed world by the mid 20th century. The movement towards individualism in the 18th and 19th centuries, and the opportunities afforded by the [[Industrial Revolution, led to housing and care using the asylum model. People were placed by, or removed from, their families (usually in infancy) and housed in large institutions (of up to 3,000 people, although some institutions were home to many more, such as the [[Philadelphia State Hospital in Pennsylvania which housed 7,000 people through the 1960s), many of which were self-sufficient through the labor of the residents. Some of these institutions provided a very basic level of education (such as differentiation between colors and basic word recognition and numeracy), but most continued to focus solely on the provision of basic needs. Conditions in such institutions varied widely, but the support provided was generally non-individualized, with aberrant behavior and low levels of economic productivity regarded as a burden to society. Heavy tranquilization and assembly line methods of support (such as "birdfeeding" and cattle herding) were the norm, and the [[medical model of disability prevailed. Services were provided based on the relative ease to the provider, not based on the human needs of the individual. Ignoring the prevailing attitude, [[Civitan International|Civitans adopted service to the developmentally disabled as a major organizational emphasis in 1952. Their earliest efforts included workshops for special education teachers and daycamps for disabled children, all at a time when such training and programs were almost nonexistent. In the United States, the segregation of people with developmental disabilities wasn't widely questioned by academics or policy-makers until the 1969 publication of [[Wolf Wolfensberger's seminal work "The Origin and Nature of Our Institutional Models", drawing on some of the ideas proposed by SG Howe 100 years earlier. This book posited that society characterizes people with disabilities as [[deviant, sub-human and burdens of charity, resulting in the adoption of that "deviant" role. Wolfensberger argued that this dehumanization, and the segregated institutions that result from it, ignored the potential productive contributions that all people can make to society. He pushed for a shift in policy and practice that recognized the human needs of "retardates" and provided the same basic human rights as for the rest of the population. The publication of this book may be regarded as the first move towards the widespread adoption of the [[social model of disability in regard to these types of disabilities, and was the impetus for the development of government strategies for desegregation.Successful [[lawsuits against governments and an increasing awareness of human rights and self-advocacy also contributed to this process, resulting in the passing in the U.S. of the [[Civil Rights of Institutionalized Persons Act in 1980. From the 1960s to the present, most U.S. states have moved towards the elimination of segregated institutions. Along with the work of Wolfensberger and others including [[Gunnar Dybwad|Gunnar and [[Rosemary Ferguson Dybwad|Rosemary Dybwad, a number of scandalous revelations around the horrific conditions within state institutions created public outrage that led to change to a more community-based method of providing services. By the mid-1970s, most governments had committed to de-institutionalization, and had started preparing for the wholesale movement of people into the general community, in line with the principles of [[normalisation (people with disabilities)|normalization. In most countries, this was essentially complete by the late 1990s, although the debate over whether or not to close institutions persists in some states, including Massachusetts. Individuals with developmental disabilities are not fully integrated into society. Person Centered Planning and Person Centered Approaches are seen as methods of addressing the continued labeling and exclusion of socially devalued people, such as people with a developmental disability label, encouraging a focus on the person as someone with capacities and gifts, as well as support needs.


Services and support

Today, support services are provided by government agencies, [[non-governmental organizations and by [[private sector providers. Support services address most aspects of life for people with developmental disabilities, and are usually theoretically based in community inclusion, using concepts such as [[social role valorization and increased self-determination (using models such as [[Person Centred Planning). Support services are funded through government block funding (paid directly to service providers by the government), through individualized funding packages (paid directly to the individual by the government, specifically for the purchase of services) or privately by the individual (although they may receive certain subsidies or discounts, paid by the government). There also are a number of non-profit agencies dedicated to enriching the lives of people living with developmental disabilities and erasing the barriers they have to being included in their community.


Education and training

Education and training opportunities for people with developmental disabilities have expanded greatly in recent times, with many governments mandating universal access to educational facilities, and more students moving out of [[special schools and into [[mainstreaming in education|mainstream classrooms with support. [[Post-secondary education and [[vocational education|vocational training is also increasing for people with these types of disabilities, although many programs offer only segregated "access" courses in areas such as [[literacy, [[numeracy and other basic skills. Legislation (such as the UK's [[Disability Discrimination Act 1995) requires educational institutions and training providers to make "reasonable adjustments" to curriculum and teaching methods in order to accommodate the learning needs of students with disabilities, wherever possible. There are also some vocational training centers that cater specifically to people with disabilities, providing the skills necessary to work in integrated settings, one of the largest being [[Dale Rogers Training Center in [[Oklahoma City. (See also [[Intensive interaction)


At-home and community support

Many people with developmental disabilities live in the general community, either with family members, in supervised-group homes or in their own homes (that they rent or own, living alone or with [[flatmates). At-home and community supports range from one-to-one assistance from a support worker with identified aspects of daily living (such as [[budgeting, [[shopping or paying bills) to full 24-hour support (including assistance with household tasks, such as [[cooking and [[Housekeeping|cleaning, and personal care such as showering, dressing and the administration of medication). The need for full 24-hour support is usually associated with difficulties recognizing safety issues (such as responding to a fire or using a telephone) or for people with potentially dangerous medical conditions (such as asthma or diabetes) who are unable to manage their conditions without assistance. In the [[United States, a support worker is known as a [[Direct Support Professional (DSP). The DSP works in assisting the individual with their ADLs and also acts as an [[advocate for the individual with a developmental disability, in communicating their needs, self-expression and [[objective (goal)|goals. Supports of this type also include assistance to identify and undertake new hobbies or to access community services (such as education), learning appropriate behavior or recognition of community norms, or with relationships and expanding circles of friends. Most programs offering at-home and community support are designed with the goal of increasing the individual's independence, although it is recognized that people with more severe disabilities may never be able to achieve full independence in some areas of daily life.


Residential accommodation

Some people with developmental disabilities live in residential accommodation (also known as group homes) with other people with similar assessed needs. These homes are usually staffed around the clock, and usually house between 3 and 15 residents. The prevalence of this type of support is gradually decreasing, however, as residential accommodation is replaced by at-home and community support, which can offer increased choice and self-determination for individuals. Some U.S. states still provide institutional care, such as the [[Texas State Schools. The type of residential accommodation is usually determined by the level of developmental disability and mental health needs.


Employment support

Employment support usually consists of two types of support: * Support to access or participate in integrated employment, in a workplace in the general community. This may include specific programs to increase the skills needed for successful employment (work preparation), one-to-one or small group support for on-the-job training, or one-to-one or small group support after a transition period (such as advocacy when dealing with an employer or a bullying colleague, or assistance to complete an application for a promotion). * The provision of specific employment opportunities within segregated business services. Although these are designed as "transitional" services (teaching work skills needed to move into integrated employment), many people remain in such services for the duration of their working life. The types of work performed in business services include mailing and packaging services, cleaning, gardening and landscaping, timberwork, metal fabrication, farming, and sewing. Workers with developmental disabilities have historically been paid less for their labor than those in the general workforce, although this is gradually changing with government initiatives, the enforcement of anti-discrimination legislation and changes in perceptions of capability in the general community. In the United States, a variety of initiatives have been launched in the past decade to reduce unemployment among workers with disabilities—estimated by researchers at over 60%. Most of these initiatives are directed at employment in mainstream businesses. They include heightened placement efforts by the community agencies serving people with developmental disabilities, as well as by government agencies. Additionally, state-level initiatives are being launched to increase employment among workers with disabilities. In California, the state senate in 2009 created the Senate Select Committee on Autism and Related Disorders. The Committee has been examining additions to existing community employment services, and also new employment approaches. Committee member Lou Vismara, chairman of the MIND Institute at [[University of California, Davis, is pursuing the development of a planned community for persons with autism and related disorders in the [[Sacramento region. Another committee member, [[Michael S. Bernick|Michael Bernick, the former director of the state labor department, has established a program at the California state university system, starting at [[California State University East Bay, to support students with autism on the college level. Other Committee efforts include mutual support employment efforts, such as disability job networks, job boards, and identifying business lines that build on the strengths of persons with disabilities. Though efforts are being made to integrate individuals with developmental disabilities into the workforce, businesses are still reluctant to employ individuals with IDD because of their poor communication skills and emotional intelligence. High functioning individuals with developmental disabilities can find it difficult to work in an environment that requires teamwork and direct communication due to their lack of social awareness. Working with employers to better understand the disorders and barriers that may come from the struggles associated with them, can greatly impact the quality of life for these individuals.


Day services

Non-vocational day services are usually known as day centers, and are traditionally segregated services offering training in life skills (such as meal preparation and basic literacy), center-based activities (such as crafts, games and music classes) and external activities (such as day trips). Some more progressive day centers also support people to access vocational training opportunities (such as college courses), and offer individualized outreach services (planning and undertaking activities with the individual, with support offered one-to-one or in small groups). Traditional day centers were based on the principles of [[occupational therapy, and were created as [[respite care|respite for family members caring for their loved ones with disabilities. This is slowly changing, however, as programs offered become more skills-based and focused on increasing independence.


Advocacy

[[Advocacy is a burgeoning support field for people with developmental disabilities. Advocacy groups now exist in most jurisdictions, working collaboratively with people with disabilities for systemic change (such as changes in policy and legislation) and for changes for individuals (such as claiming welfare benefits or when responding to abuse). Most advocacy groups also work to support people, throughout the world, to increase their capacity for [[self-advocacy, teaching the skills necessary for people to advocate for their own needs.


Other types of support

Other types of support for people with developmental disabilities may include: * Therapeutic services, such as speech therapy, occupational therapy, physical therapy, massage, aromatherapy, art, dance/movement or music therapy * Supported holidays * Short-stay respite services (for people who live with family members or other unpaid carers) * Transport services, such as dial-a-ride or free bus passes * Specialist behavior support services, such as high-security services for people with high-level, high-risk challenging behaviors * Specialist relationships and sex education. Programs are set up around the country in hopes to educate individuals with and without developmental disabilities. Studies have been done testing specific scenarios on how what is the most beneficial way to educate people. Interventions are a great way to educate people, but also the most time consuming. With the busy schedules that everybody has, it is found to be difficult to go about the intervention approach. Another scenario that was found to be not as beneficial, but more realistic in the time sense was Psychoeducational approach. They focus on informing people on what abuse is, how to spot abuse, and what to do when spotted. Individuals with developmental disabilities don't only need the support programs to keep them safe, but everybody in society needs to be aware of what is happening and how to help everybody prosper.Lund, Emily.
