Intellectual Disability

A condition characterized by significant limitations in both intellectual functioning (reasoning, learning, problem-solving) and adaptive behavior (conceptual, social, and practical skills) that originates before age 22. The DSM-5 and ICD-11 classify severity levels based on adaptive functioning and support needs rather than IQ scores alone. For digital accessibility, intellectual disability requires consideration of cognitive load, plain language, consistent navigation, and appropriate pacing of content to support comprehension and independent use of technology.
