Age-Related Impairment

Functional limitations that commonly develop with advancing age, often involving multiple interacting mild impairments rather than a single major disability. Age-related impairments may affect vision (presbyopia, reduced contrast sensitivity, cataracts), hearing (presbycusis), motor control (tremor, reduced dexterity, slowed reaction time), and cognition (memory, attention, processing speed). Unlike traditional assistive technology users who may have adapted to a single major impairment, older adults often experience gradual, cumulative decline across multiple functions. This makes traditional accessibility solutions—which assume compensatory abilities in unaffected domains—less effective and requires holistic, multi-modal design approaches.
