Criteria for Diagnosing Intellectual Disability (Formerly Mental Retardation)

Intellectual disability is a neurodevelopmental disorder characterized by limitations in intellectual functioning and adaptive behavior, originating before the age of 18. Diagnosis involves assessing several key criteria:

1. Intellectual Functioning: Intellectual functioning is measured using standardized intelligence quotient (IQ) tests. A score below 70 typically indicates significant limitations in intellectual functioning, although this may vary based on cultural and contextual factors.

2. Adaptive Behavior: Adaptive behavior refers to the individual's ability to effectively navigate daily life tasks and adapt to social and environmental demands. This includes communication, self-care, social skills, and problem-solving abilities. Significant deficits in adaptive behavior must be evident relative to the individual's age and cultural background.

3. Onset During Developmental Period: Intellectual disability manifests during childhood or adolescence. The impairments in intellectual functioning and adaptive behavior become apparent before the age of 18, distinguishing it from conditions that arise later in life.

4. Severity Levels: Intellectual disability is categorized into severity levels based on the degree of impairment in intellectual functioning and adaptive behavior. These levels include mild, moderate, severe, and profound, each reflecting varying degrees of support needed for daily functioning.

5. Functional Limitations: Intellectual disability results in limitations that affect various aspects of life, such as academic achievement, employment, social interactions, and independent living skills. The extent of these functional limitations is assessed to determine the individual's support needs and intervention strategies.

6. Exclusionary Criteria: Diagnosis of intellectual disability involves ruling out other medical, neurological, or psychiatric conditions that could account for the observed impairments. Additionally, environmental factors like socio-economic disadvantage or cultural differences are considered to ensure accurate diagnosis and appropriate intervention.

Overall, diagnosing intellectual disability requires a thorough assessment of intellectual functioning, adaptive behavior, onset during the developmental period, severity levels, functional limitations, and exclusionary criteria. This comprehensive evaluation guides intervention planning to support individuals with intellectual disability in achieving their full potential and enhancing their quality of life.
