The amendments make several important changes to the ADA. First, although the definition of disability is unchanged, Congress makes clear that it is "reinstating a broad scope of protection to be available under the ADA" (Sec. 2(b)(1)). This is to counter the cramped reading of disability by the courts that led to this legislation. Second, Congress expands the definition of major life activities to include two types of examples (Sec. 4(a)(2)). Major life activities now "include, but are not limited to, caring for oneself, performing manual tasks, seeing, hearing, eating, sleeping, walking, standing, lifting, bending, speaking, breathing, learning, reading, concentrating, thinking, communicating, and working." In addition, a new category of major life activities called "major bodily functions" has been added and is defined as "the operation of a major bodily function, including but not limited to, functions of the immune system, normal cell growth, digestive, bowel, bladder, neurological, brain, respiratory, circulatory, endocrine, and reproductive functions." In perhaps the most significant change, the amendments state that the determination of whether an impairment substantially limits a major life activity is to be made "without regard to the ameliorative effects of mitigating measures." The amendments then list a number of examples that are not to be considered mitigating measures, including medication, medical supplies, prosthetics, hearing aids, and other measures (Sec. 4(a)(3)(E)(i)-(iii)).
