Intellectual disability, also known as cognitive disability or mental retardation (historically termed as such), refers to a developmental condition characterized by limitations in intellectual functioning and adaptive behavior. This condition originates before the age of 18 and impacts various aspects of an individual’s daily life, including communication, learning, social interaction, and independent living skills.
Causes and Types
Intellectual disability can result from various factors, including genetic conditions, prenatal exposure to toxins or infections, complications during birth, and postnatal factors such as brain injury or illness. It can be categorized into different types based on its severity and underlying causes:
-
Mild Intellectual Disability: Individuals with mild intellectual disability often have IQ scores between 50-70. They may face challenges in academic settings, require support in certain tasks, and may function well in structured environments with assistance.
-
Moderate Intellectual Disability: This type involves IQ scores between 35-49. Individuals with moderate intellectual disability typically require more support in areas such as communication, social skills, and daily living activities. They may benefit from special education programs and supervised living arrangements.
-
Severe Intellectual Disability: IQ scores in the range of 20-34 are characteristic of severe intellectual disability. Individuals in this category often require significant assistance and supervision in all aspects of daily life, including personal care, safety, and communication.
-
Profound Intellectual Disability: This is the most severe form, with IQ scores below 20. Individuals with profound intellectual disability have profound limitations in cognitive functioning and often require intensive support and care throughout their lives.
Diagnosis and Assessment
Diagnosing intellectual disability involves comprehensive assessments that evaluate intellectual functioning, adaptive behavior, and the individual’s developmental history. Professionals such as psychologists, psychiatrists, and developmental pediatricians may conduct standardized tests, observe behavior, and gather information from caregivers and educators to make an accurate diagnosis.
The Diagnostic and Statistical Manual of Mental Disorders (DSM-5) provides criteria for diagnosing intellectual disability, considering factors such as IQ scores, adaptive functioning across multiple domains, and the onset of symptoms during childhood.
