Is 'Down syndrome' capitalized?

Yes, 'Down' is always capitalized as it is derived from a person's name (Dr. John Langdon Down).

What is the preferred way to refer to someone with this condition?

Person-first language is widely preferred: 'a person/child/individual with Down syndrome'. This puts the person before the diagnosis.

Are 'Down syndrome' and 'Trisomy 21' the same thing?

Essentially, yes. Trisomy 21 is the specific genetic diagnosis (three copies of chromosome 21), which is the cause of Down syndrome.

Is the term 'mongoloid' acceptable?

No. This is an archaic and offensive term that is no longer used in medical or respectful discourse.

My Flashcards

Definition

Meaning

A genetic condition caused by the presence of an extra chromosome 21, typically resulting in developmental delays, characteristic physical features, and often some degree of intellectual disability.

The term also refers to the medical, social, and educational field associated with the study, support, and inclusion of individuals with this condition.

Linguistics

Semantic Notes

The term is a proper noun, derived from John Langdon Down, the physician who described the syndrome. Modern usage strongly prefers person-first language (e.g., 'a person with Down syndrome' or 'an individual who has Down syndrome') to emphasize the person before the diagnosis. The spelling 'Down's syndrome' (with an apostrophe) is also common, particularly in British English.

Dialectal Variation

British vs American Usage

Differences

UK English more commonly uses 'Down's syndrome' with the possessive apostrophe-s. US English predominantly uses 'Down syndrome' without the apostrophe.

Connotations

Identical in both varieties. The connotations are purely medical/social. Both varieties observe the shift towards person-first language.

Frequency

Equally frequent in relevant medical, educational, and social discourse in both regions.

Learning

Memory Aids

Mnemonic

Think of the **D** in Down for the extra **D**ose of chromosome 21 (three instead of the typical two).

Conceptual Metaphor

Often framed through a 'journey' metaphor ('navigating life with Down syndrome') or a 'spectrum' metaphor (referring to the wide range of abilities).

Watch out

Common Pitfalls

Translation Traps (for Russian speakers)

Avoid direct translation like 'синдром вниз' which is meaningless. The standard Russian term is 'синдром Дауна'.
Be aware that outdated and offensive terms like 'монголизм' or 'даунизм' are unacceptable in modern English and most professional Russian.

Common Mistakes

Using 'Down' as an adjective to describe a person (e.g., 'a Down child' is offensive; use 'a child with Down syndrome').
Omitting the capital 'D' in 'Down'.
Using outdated terms like 'mongoloid'.
