Cognitive Dysfunction

A broad term encompassing conditions that affect cognitive functions such as memory, attention, problem-solving, learning, language, and executive function. Cognitive dysfunction ranges from mild impairments (age-related memory decline, mild cognitive impairment) to major conditions (dementia, intellectual disabilities, acquired brain injury). In digital accessibility, cognitive dysfunction is often underserved relative to sensory and motor disabilities despite affecting a larger proportion of the population. Design considerations include simplified interfaces, consistent navigation, memory aids, reduced cognitive load, plain language, and tolerance for errors.
