Cognitive functioning refers to the ability to learn, reason, problem-solve, and remember. Adaptive skills are the practical and social skills that people need to function in everyday life, such as communication, self-care, social interaction, and work.

In this blog post, I will explain more about what intellectual disability is, what causes it, how it is diagnosed, and how it can be treated and managed. I hope this post will help you understand more about this condition and the people who live with it.


What is intellectual disability?


According to the American Psychiatric Association (APA), intellectual disability is a neurodevelopmental disorder that involves significant limitations in intellectual functioning and adaptive behavior. Intellectual functioning refers to the ability to reason, problem-solve, plan, learn, and understand complex ideas. Adaptive behavior refers to the skills needed to perform everyday tasks, such as communication, social interaction, self-care, and work.

Intellectual disability is not a disease or a mental illness. It is a condition that affects how the brain develops and works. It usually starts before the age of 18 and lasts throughout a person's life.

People with intellectual disability may have difficulties in some or all of these areas, depending on the severity of their condition and the support they receive. Intellectual disability is not a disease or a mental illness. It is a developmental disorder that usually occurs before birth or during childhood due to genetic factors, environmental influences, or health problems.

The term intellectual disability has replaced other terms that were previously used, such as mental retardation or mental handicap. These terms are considered outdated and offensive, as they imply that people with intellectual disability are less valuable or capable than others. Intellectual disability is not a label that defines a person's identity or worth. It is a description of a condition that affects how a person learns and interacts with the world.

People with intellectual disability are diverse and unique individuals who have their own strengths, interests, preferences, and goals. They can learn new skills and achieve their potential with appropriate support and opportunities. They can also contribute to society in meaningful ways and enjoy fulfilling lives.

Some of the ways that we can support people with intellectual disability are:
  • Respect their dignity and human rights. Treat them as equal members of society who deserve respect, inclusion, and participation.
  • Recognize their abilities and potential. Provide them with opportunities to learn, grow, and express themselves according to their interests and talents.
  • Provide them with individualized support. Understand their needs and preferences and tailor the support accordingly. Use positive and person-centered approaches that focus on their strengths and goals.
  • Promote their independence and self-determination. Encourage them to make choices and decisions about their own lives. Support them to develop skills and confidence to manage their own affairs.
  • Foster their social inclusion and belonging. Help them to build relationships and networks with family, friends, peers, and community members. Support them to access education, employment, health care, recreation, and other services that they need and want.
  • Advocate for their rights and interests. Speak up for them when they face discrimination, abuse, or neglect. Support them to access justice and legal protection when needed.
Intellectual disability is a condition that affects how a person thinks and learns. It does not define who they are or what they can do. People with intellectual disability are valuable members of society who deserve respect, support, and opportunities to live fulfilling lives.


Tipes of intellectual disability


The severity of intellectual disability can vary from person to person. The APA uses four levels of severity to describe intellectual disability: mild, moderate, severe, and profound. These levels are based on the degree of impairment in intellectual functioning and adaptive behavior, as well as the level of support needed by the person.

1. Mild intellectual disability: 

This is the most common level of severity, affecting about 85% of people with intellectual disability. People with mild intellectual disability can learn academic and practical skills with appropriate support and guidance. They can also live independently or with minimal assistance in adulthood. However, they may have difficulties with abstract thinking, complex reasoning, and social judgment. They may also need more time and repetition to learn new things.

2. Moderate intellectual disability: 

This level of severity affects about 10% of people with intellectual disability. People with moderate intellectual disability can learn basic academic and practical skills with moderate support and supervision. They can also perform some work and self-care tasks with assistance. However, they may have significant delays in language development, memory, and problem-solving skills. They may also need ongoing support to cope with daily challenges and changes.

3. Severe intellectual disability: 

This level of severity affects about 3-4% of people with intellectual disability. People with severe intellectual disability can learn some communication and self-care skills with intensive support and training. They can also participate in some simple activities at home or in the community with supervision. However, they may have very limited language abilities, cognitive skills, and motor coordination. They may also need constant care and protection throughout their lives.

4. Profound intellectual disability: 

This level of severity affects about 1-2% of people with intellectual disability. People with profound intellectual disability can learn some basic sensory and motor skills with extensive support and stimulation. They can also express some emotions and preferences through nonverbal communication. However, they may have very minimal awareness of their surroundings, cognitive abilities, and physical capacities. They may also depend on others for all aspects of their care and well-being.


What are the characteristics of intellectual disability?


Intellectual disability is a term that refers to a condition in which a person has significant limitations in cognitive functioning and adaptive skills. Cognitive functioning includes reasoning, problem-solving, learning, and memory. Adaptive skills include communication, social, and practical skills that enable a person to function independently in daily life.

According to the American Association on Intellectual and Developmental Disabilities (AAIDD), intellectual disability is characterized by:
  • An IQ score below 70 on a standardized test of intelligence
  • Significant limitations in at least two areas of adaptive skills, such as communication, self-care, social skills, home living, health and safety, functional academics, leisure, and work
  • Onset before the age of 18
The degree of intellectual disability can vary from mild to profound, depending on the level of cognitive and adaptive functioning. People with mild intellectual disability may be able to live independently with minimal support, while people with profound intellectual disability may require constant supervision and care.

The causes of intellectual disability can be genetic, environmental, or unknown. Some examples of genetic causes are Down syndrome, fragile X syndrome, and phenylketonuria (PKU). Some examples of environmental causes are prenatal exposure to alcohol or drugs, infections, malnutrition, or brain injury.

Intellectual disability is not a disease or a mental illness. It is a lifelong condition that affects how a person learns, communicates, and interacts with others. People with intellectual disability can have strengths and abilities, as well as challenges and needs. They can learn new skills and achieve their goals with appropriate support and opportunities.

The diagnosis of intellectual disability is based on a comprehensive assessment that includes intelligence testing, adaptive behavior assessment, developmental history, medical evaluation, and observation. The assessment should be conducted by a qualified professional who is familiar with the person's cultural and linguistic background.

The treatment of intellectual disability involves providing individualized supports and services that enhance the person's functioning and quality of life. Supports and services may include education, therapy, vocational training, health care, social activities, and advocacy. The type and intensity of supports and services depend on the person's needs and preferences.

People with intellectual disability have the same human rights as everyone else. They deserve respect, dignity, inclusion, and equality. They can contribute to society in meaningful ways if they are given the opportunity and support. They can also enjoy fulfilling relationships with their family, friends, and community.


What You Need to Know About Intellectual Disability?

Intellectual disability is a term that describes a condition in which a person has limitations in their cognitive and adaptive abilities. 

Cognitive abilities include skills such as learning, reasoning, problem-solving, and memory. Adaptive abilities include skills such as communication, self-care, social interaction, and daily living. 

People with intellectual disability may need more support than others to achieve their goals and participate in their communities.
 
Intellectual disability can have different causes and levels of severity. Some of the causes may occur before, during, or after birth. Some of the causes may be genetic, such as Down syndrome or fragile X syndrome. 

Some of the causes may be environmental, such as exposure to alcohol, infections, or toxins during pregnancy or early childhood. Some of the causes may be unknown.

The level of intellectual disability can vary from mild to profound, depending on the person's IQ score and adaptive functioning. IQ score is a measure of intellectual potential that is based on standardized tests. 

The average IQ score is 100, and most people score between 85 and 115. People with intellectual disability typically score below 70 on IQ tests. Adaptive functioning is a measure of how well a person can perform everyday tasks and cope with challenges. 

People with intellectual disability may have difficulties in one or more areas of adaptive functioning, such as communication, self-care, social skills, academic skills, work skills, safety skills, or leisure skills.

Intellectual disability is not a disease or a mental illness. It is not contagious or curable. It is not something that a person can outgrow or overcome with effort. It is a lifelong condition that affects how a person thinks, learns, and behaves.

However, intellectual disability does not define a person's identity or potential. People with intellectual disability have strengths, talents, interests, and dreams. 

They can learn new skills and achieve their goals with appropriate support and opportunities. They can contribute to society and enjoy meaningful relationships with others.

The best way to support people with intellectual disability is to respect their dignity and human rights, recognize their individuality and diversity, and promote their inclusion and participation in all aspects of life. 

This requires collaboration among families, professionals, educators, employers, policymakers, and advocates to create accessible and supportive environments that enable people with intellectual disability to thrive.
