Disability

Disability is defined by the Americans with Disabilities Act of 1990 as "a physical or mental impairment that substantially limits one or more major life activities." An individual may also qualify as disabled if he/she has had an impairment in the past or is seen as disabled based on a personal or group standard or norm. Such impairments may include physical, sensory, and cognitive or intellectual impairments. Mental disorders (also known as psychiatric or psychosocial disability) and various types of chronic disease may also be considered qualifying disabilities.

A disability may occur during a person's lifetime or may be present from birth.
