The definition of disability set forth in the Americans with Disabilities Act of 1990 (ADA) does not distinguish between type, severity, or duration of the disability. It states that the term ‘disability’ means, with respect to an individual, refers to:
a) a physical or mental impairment that substantially limits one or more of the major life activities of such an individual;
b) a record of such impairment; or
c) being regarded as having such an impairment.
