That's incorrect.

Federal legislation includes specific definitions of a person with a disability.

Section 504 of the 1973 Rehabilitation Act defines an individual with a disability as:

• a person who has a physical or mental impairment which substantially limits one or more major life activities such as walking, talking, seeing, hearing, speaking, breathing, working, and learning; or
  
• a person who has a record of such an impairment; or
  
• a person who is regarded as having such an impairment.
  
  

The law grants protection against discrimination to anyone who meets this definition.
