a person with especially a profound intellectual disability

Note: While the terms idiot, imbecile, and moron survive in many state codes and statutes, they are generally no longer used in both medical and legal contexts. The modern terminology distinguishes between mild, moderate, severe, and profound levels of disability. Historically persons with intellectual disabilities have been deprived of certain rights (as in not being allowed to vote). Generally today, an adult with an intellectual disability who is his or her own guardian is not deprived of these rights.
