Huntingtons Disease synonyms

Huntington’s disease is the universally accepted modern medical term for this neurodegenerative condition, though it was historically known as Huntington's chorea. While you may encounter older terms like chronic progressive chorea, these are now considered obsolete and are no longer used in clinical practice or official medical coding.

What are the historical names for Huntington’s disease?

For many decades, the condition was widely referred to as Huntington's chorea, a name derived from the Greek word "choreia," meaning dance, which describes the involuntary, jerky movements characteristic of the disease. In older medical literature, you may also find it listed as chronic progressive chorea or hereditary chorea. These terms were utilized before the complex genetic nature of Huntington’s disease was fully understood and before the discovery of the HTT gene mutation in 1993. Using these outdated names can sometimes cause confusion in modern electronic health records, which is why the medical community has standardized the nomenclature.

Why does Huntington’s disease have multiple names?

The transition in terminology reflects the evolution of our understanding of Huntington’s disease. Early descriptions focused primarily on the physical motor symptoms (the "chorea"), leading to the historical name. However, as clinicians recognized that the condition also involves profound cognitive and psychiatric symptoms, the term "chorea" was deemed too narrow. Today, Huntington’s disease is the preferred clinical term because it encompasses the full spectrum of the disorder—motor, cognitive, and behavioral—rather than just the movement-related aspects. Standardizing the name helps ensure that patients, researchers, and global health organizations are referring to the same condition, facilitating better care coordination for the 39 members of our DiseaseMaps community who are navigating this journey.

What are the official classifications for Huntington’s disease?

In global medical classification systems, the condition is consistently indexed to ensure diagnostic accuracy. Regardless of historical synonyms, you will find the condition listed under the following identifiers:

• ICD-10/ICD-11: Classified under G10 (Huntington's disease).


• OMIM (Online Mendelian Inheritance in Man): #143100 (Huntington disease).


• Orphanet: ORPHA:399 (Huntington disease).


• GARD (NIH): Rare Disease ID 6676.

Which name should I use when speaking with doctors?

When communicating with your healthcare team, it is best to use the standard term, Huntington’s disease. Using the modern name ensures that your medical records align with current clinical guidelines and international diagnostic codes. If you are reviewing older family medical records that mention "Huntington's chorea," you can confidently clarify with your neurologist or genetic counselor that you are referring to the same hereditary condition caused by the expansion of the CAG trinucleotide repeat in the HTT gene. Clear, accurate terminology helps your specialists provide the most relevant treatment and support.

Next steps

• Consult a specialist: Seek care from a neurologist or a movement disorder specialist who has specific experience in managing Huntington’s disease.


• Genetic counseling: If you or a family member is at risk, schedule a session with a clinical geneticist to discuss testing and inheritance patterns.


• Connect with community: Join our community of 39 individuals on DiseaseMaps.org to share experiences and find peer support.


• Stay informed: Monitor reputable sources like the Huntington’s Disease Society of America (HDSA) for updates on clinical trials and research.
