Mongolism definition - Medical Dictionary definitions of popular medical terms easily defined on MedTerms
Down syndrome refers to the 19th century English physician J. Langdon Down who described the condition in 1866. In great error, Langdon Down attributed the condition to a "reversion" to the "mongoloid race." He held that evolution had been reversed and there had been a sort of backslide from the superior Caucasian to the inferior Oriental race. The misnomer "mongolism" is incorrect and racist and is to be avoided.

If "caucasian" was supposed to be the more intellectually advanced race, they sure go/went to great lengths to make sure any mistake that effects all humans is blamed on other races. Old racist Caucasian medical diagnoses are very interesting.
