The Americans with Disabilities Act (ADA) has a three-part definition of disability. An individual with a disability is a person who has a physical or mental impairment that substantially limits one or more major life activities, or has a record of such an impairment, or is regarded as having such an impairment. ADA defines physical impairment as “any physiological disorder or condition, cosmetic disfigurement, or anatomical loss affecting one or more of the following body systems: neurological, musculoskeletal, special sense organs, respiratory (including speech organs), cardiovascular, reproductive, digestive, genitourinary, hemic and lymphatic, skin, and endocrine.” ADA does not list all the diseases or conditions that are covered because it is impossible to document every possible impairment.
