TYPES OF INTELLECTUAL DISABILITY


Intellectual disability, also known as intellectual developmental disorder (IDD), is a condition characterized by limitations in cognitive functioning and adaptive skills. The severity of intellectual disability can vary widely, and individuals with intellectual disabilities may require varying degrees of support in their daily lives. Here are some types of intellectual disabilities:



  • Mild Intellectual Disability:
Individuals with mild intellectual disability typically have an IQ range of 50-70. They may experience delays in childhood development, particularly in areas such as language and motor skills. During school years, they often benefit from specialized support and interventions. With appropriate assistance and accommodations, individuals with mild intellectual disability can achieve a degree of independence and often function well in a supportive environment.

  • Moderate Intellectual Disability:
Moderate intellectual disability is characterized by an IQ range of 35-50. Individuals with this level of disability may experience delays in multiple areas of development, including communication and self-care skills. They often require more substantial support in their daily lives and may benefit from structured environments, specialized education, and vocational training to develop practical skills and maximize their potential for independence.

  • Severe Intellectual Disability:
Severe intellectual disability is characterized by an IQ range of 20-35. Individuals with severe intellectual disability typically have significant impairments in cognitive functioning and adaptive behavior. They often experience delays in all developmental domains and may have difficulties with communication, mobility, and self-care skills. They usually require ongoing support and assistance throughout their lives, including specialized educational programs, therapies, and residential care.

  • Profound Intellectual Disability:
Profound intellectual disability refers to the most severe level of impairment, with an IQ below 20. Individuals with profound intellectual disability have very limited cognitive functioning and significant challenges in adaptive behavior. They often have multiple physical and sensory impairments as well. They require extensive support and care, including specialized education, therapies, and assistance with daily activities.


It's important to remember that intellectual disability is a complex and diverse condition, and each individual's abilities and challenges can vary widely, even within the same type or level of disability. A comprehensive assessment conducted by healthcare professionals can help determine the specific type and level of intellectual disability in an individual, enabling appropriate support and interventions to be implemented.
