Is Cushing's disease the same as Cushing's syndrome?

No. Cushing's syndrome is the general term for the state of excess cortisol. Cushing's disease is a specific type, accounting for about 70% of cases, caused by a pituitary tumour secreting ACTH.

Can Cushing's disease be cured?

Yes, it can often be cured, especially if the causative pituitary tumour is successfully removed via surgery. However, treatment can be complex and may involve long-term management.

What is the most common symptom of Cushing's disease?

Central weight gain, particularly in the face (moon face) and abdomen, with slender limbs, is one of the most recognisable symptoms.

Who gets Cushing's disease?

It is more common in women than men and most frequently diagnosed in adults aged 20-50, though it can occur at any age.

My Flashcards

Definition

Meaning

A medical condition caused by prolonged exposure to high levels of the hormone cortisol, specifically resulting from a pituitary tumour that overproduces adrenocorticotropic hormone (ACTH).

A specific, less common form of Cushing's syndrome, distinguished by its pituitary origin. It represents a cluster of physical and metabolic symptoms (like weight gain, muscle weakness, and mood changes) due to the body's cortisol excess, requiring precise diagnostic differentiation from adrenal or exogenous causes.

Linguistics

Semantic Notes

The term is often used interchangeably with 'Cushing's syndrome' in casual discourse, but in medical contexts, 'disease' is reserved for the specific pituitary-dependent aetiology. The possessive form 'Cushing's' is standard. Not to be confused with Cushing's triad (a different medical sign related to intracranial pressure).

Examples

By Part of Speech

verb

British English

The tumour was causing the adrenal glands to overfunction.

American English

The condition manifested after the tumor began secreting excess ACTH.

adjective

British English

Cushing's disease symptoms often develop gradually.
The Cushing's disease diagnosis was confirmed by MRI.

American English

The patient exhibited classic Cushing's disease features.
Cushing's disease management requires a specialist.

Examples

By CEFR Level

Learning

Memory Aids

Mnemonic

Think: The pituitary gland is CUSHING (pushing) out too much ACTH, causing the disease.

Conceptual Metaphor

A runaway production line (the pituitary gland overproducing signals, leading to a toxic buildup of cortisol).

Watch out

Common Pitfalls

Translation Traps (for Russian speakers)

Avoid direct translation that omits the possessive 's' (*болезнь Кушинг). The correct medical term is 'болезнь Иценко — Кушинга' or 'болезнь Кушинга'.
Do not confuse with 'синдром Кушинга' (Cushing's syndrome), which is the broader category.

Common Mistakes

Misspelling as 'Cushing disease' (omitting apostrophe+s).
Using 'Cushing's' as an adjective without 'disease' or 'syndrome' in formal writing (e.g., 'She has Cushing's.').
Confusing it with the more general 'Cushing's syndrome'.
