29 CFR Part 1630, Regulations to Implement the Equal Employment Provisions of the ADA (Title I Regulations with amendments issued through May 2016)

(ii) Applying the principles set forth in paragraphs (j)(1)(i) through (ix) of this section, the individualized assessment of some types of impairments will, in virtually all cases, result in a determination of coverage under paragraphs (g)(1)(i) (the “actual disability” prong) or (g)(1)(ii) (the “record of” prong) of this section. Given their inherent nature, these types of impairments will, as a factual matter, virtually always be found to impose a substantial limitation on a major life activity. Therefore, with respect to these types of impairments, the necessary individualized assessment should be particularly simple and straightforward.
