Intellectual Disabilities in Children

Intellectual Disability (ID) is a condition characterised by significant limitations in both intellectual functioning and adaptive behaviour, which covers many everyday social and practical skills. This condition is usually evident before the age of 18 and impacts the individual’s cognitive abilities, making it challenging to learn and apply new skills. 

Intellectual Disabilities vary widely in severity and can affect anyone, regardless of ethnicity, background, or socioeconomic status.

For parents, learning that their child has an ID can be overwhelming and emotionally challenging. However, with the right support and resources, families can work together to nurture and support their child’s development. 

We’re here to help parents to understand ID, recognise early indicators, navigate the diagnostic process, and find ways to manage as a family.

What is the Definition of Intellectual Disability?

Intellectual Disability (ID) is a developmental condition that emerges before the age of 18 and is characterised by significant limitations in both Intellectual Functioning and adaptive behaviour. Intellectual functioning refers to general mental capabilities, including reasoning, problem-solving, planning, abstract thinking, and learning from experience. 

It is often quantified using standardised IQ tests, with scores below 70-75 typically indicating limitations in intellectual functioning.

Adaptive behaviour encompasses a range of practical, social, and conceptual skills that people learn and perform in their daily lives. These skills include communication, self-care, social skills, leisure activities, and work. Limitations in adaptive behaviour mean that individuals with ID may struggle with everyday tasks and require support to achieve a level of independence.

The diagnosis of ID is not solely based on IQ scores. A comprehensive assessment of adaptive behaviour, cultural and linguistic background, community environment, and any coexisting conditions is essential for an accurate diagnosis. Professionals use standardised tools to evaluate adaptive behaviours in real-life settings, ensuring that the diagnosis reflects the individual’s abilities and needs.

ID varies widely in severity, ranging from mild to profound. Individuals with mild ID may achieve a certain degree of independence and success in education and employment with appropriate support. In contrast, those with severe or profound ID often require more extensive and ongoing assistance throughout their lives.

Understanding ID involves recognising that it is a multifaceted condition affecting various aspects of an individual’s life. With early intervention, specialised education, and support services, individuals with ID can lead meaningful, productive lives and contribute positively to their communities. 

The goal is to provide the necessary resources and support to help them reach their full potential and enhance their quality of life.

Resources and Support for Intellectual Disabilities

What Causes Intellectual Disabilities?

The causes of Intellectual Disabilities are varied and can be attributed to numerous factors, including:

  • Genetic Conditions: Certain genetic conditions, such as Down syndrome and Fragile X syndrome, are known to cause Intellectual Disabilities.
  • Complications During Pregnancy: Problems during pregnancy, such as infections, malnutrition, exposure to toxins, or lack of oxygen, can lead to Intellectual Disabilities.
  • Birth Complications: Premature birth, low birth weight, and lack of oxygen during delivery can contribute to Intellectual Disabilities.
  • Illness or Injury: Childhood diseases, lead poisoning, severe malnutrition, and head injuries can also result in Intellectual Disabilities.

What Are The Primary Indicators of Intellectual Disabilities?

Primary Early Indicators of Infants with Intellectual Disability

  • Delayed developmental milestones (e.g., sitting up, crawling, walking)
  • Difficulty feeding or sucking
  • Limited response to their environment
  • Lack of curiosity or interest in surroundings

Primary Early Indicators of Children with Intellectual Disability

  • Delays in speech and language development
  • Difficulty with learning basic concepts (e.g. numbers, colours)
  • Problems with social interactions and understanding social cues
  • Struggles with problem-solving and logical thinking

  • Difficulty in making and maintaining friendships
  • Limited practical and daily living skills
  • Struggles with decision-making and independent living tasks

Diagnostic Criteria of Intellectual Disability and How To Get a Diagnosis

Diagnostic Criteria

ID is typically diagnosed using a combination of standardised tests that assess intellectual functioning (IQ tests) and adaptive behaviour. Key criteria include:

  • Intellectual Functioning: An IQ score of approximately 70 or below.
  • Adaptive Behaviour: Significant limitations in adaptive skills, such as communication, self-care, social skills, and daily living activities.
  • Onset During Developmental Period: The condition must manifest before the age of 18.

How To Get a Diagnosis:

Initial Concerns and Observations 

Parents or caregivers noticing developmental delays or behavioural issues should consult with a general practitioner (GP) or paediatrician.

Referral to Specialists

The GP may refer the child to specialists, such as a developmental paediatrician, child psychologist, or psychiatrist, for a comprehensive assessment.

Assessment and Testing 

The specialist will conduct a thorough evaluation, including:

  • Detailed medical and family history
  • Physical examination to rule out other conditions
  • Standardised IQ tests and assessments of adaptive behaviour
  • Observations and reports from parents, teachers, and other caregivers

Diagnosis and Support Plan

If an ID is diagnosed, the specialist will work with the family to develop a tailored support plan, which may include:

  • Early intervention programs
  • Special education services
  • Therapies (e.g. Speech Therapy, Occupational Therapy)
  • Support groups and resources for parents

What Other Disorders Are Associated With Intellectual Disability?

ID often coexists with other developmental, medical, and psychiatric conditions, which can complicate diagnosis and management. Understanding these associated disorders is essential for providing comprehensive care and support.

  • Autism Spectrum Disorder (ASD): Many individuals with ID also have Autism Spectrum Disorder, characterised by challenges in social communication and repetitive behaviours. The overlap between ID and ASD requires tailored interventions that address both cognitive and social-emotional needs.
  • Attention-Deficit/Hyperactivity Disorder (ADHD): ADHD is another common co-occurring condition. Children with both ID and ADHD may exhibit hyperactivity, impulsivity, and difficulty maintaining attention, necessitating specialised behavioural and educational strategies.
  • Seizure Disorders: Epilepsy and other seizure disorders are more prevalent in individuals with ID. Regular monitoring and appropriate medical management are essential to control seizures and minimise their impact on daily life.
  • Sensory Processing Issues: Many people with ID experience difficulties in processing sensory information, leading to hypersensitivity or hypersensitivity to stimuli like sound, light, and touch. Occupational therapy can help manage these sensory challenges.
  • Behavioural and Emotional Disorders: Anxiety, depression, and other mood disorders are also common among individuals with ID. These conditions can exacerbate the challenges associated with ID, making mental health support an integral part of comprehensive care.

Recognising and addressing these associated disorders is vital for creating effective, individualised care plans that improve the overall well-being and quality of life for individuals with ID.

Child Intellectual Disability Therapy

What Support Does A Child With Intellectual Disability Need?

Children with ID benefit immensely from a range of support services designed to address their unique needs and help them achieve their full potential. 

These services aim to enhance their cognitive, social, emotional, and practical skills, enabling them to participate more fully in everyday life. Here are some key support services and how they help:

  • Early Intervention Programs: These programs provide specialised therapies and educational support for young children showing signs of developmental delays. Early intervention is crucial as it can significantly improve a child’s developmental trajectory and outcomes. These programs often include a combination of physical, speech, and occupational therapies tailored to the child’s specific needs.
  • Special Education Services: Tailored educational programs and resources accommodate the learning needs of children with ID. Special education teachers use individualised education plans (IEPs) to set achievable goals and provide the necessary support for academic progress. This might include modified curricula, one-on-one teaching, and adaptive learning technologies.
  • Speech Pathology: Speech Pathologists work with children to improve their communication skills, which can be a significant challenge for those with ID. They help with speech clarity, language development, social communication, and alternative communication methods (e.g. sign language or communication devices). Effective communication enhances a child’s ability to express needs, interact socially, and perform better academically.
  • Occupational Therapy: Occupational Therapists help children develop the skills needed for daily living. These include fine motor skills (like writing and buttoning clothes), sensory processing, self-care (e.g. dressing, eating), and play skills. By focusing on practical activities, Occupational Therapy promotes greater independence and participation in various aspects of life.
  • Social Skills Training: Programs designed to enhance social interactions teach children how to communicate effectively, understand social cues, and develop relationships. These skills are essential for making friends, succeeding in school, and participating in community activities.
  • Behavioural Therapy: Behavioural therapists work with children to manage and reduce challenging behaviours, such as aggression or self-injury. They use techniques like positive reinforcement, structured routines, and behaviour modification plans to promote appropriate behaviours and improve emotional regulation.
  • Medical Care: Regular medical check-ups and management of any associated health conditions, such as epilepsy or ADHD, are vital. Paediatricians and specialists ensure that the child’s physical health needs are met and that any medications are appropriately managed.
  • Assistive Technology: Various devices and technologies can support children with ID. These include communication devices, adaptive tools for learning and daily activities, and sensory aids to help manage sensory processing issues. Assistive technology enhances independence and accessibility.
  • Family Support and Training: Educating and training family members on how to support their child’s development is essential. Workshops, counselling, and informational resources empower parents and caregivers to implement effective strategies at home and advocate for their child’s needs.

By utilising these support services, children with ID can develop their skills, gain independence, and participate more fully in everyday life. 

Each service plays a critical role in addressing different aspects of the child’s development, ensuring a holistic approach to their care and growth.
