* Huntington's disease is a neurodegenerative disease and most common inherited cause of chorea. The condition was formerly called Huntington's chorea but was renamed because of the important non-choreic features including cognitive decline and behavioural change.

Other genetic causes of chorea are rare. They include the classical Huntington's disease 'mimic' or phenocopy syndromes, called Huntington's disease-like syndrome types 1, 2 and 3; inherited prion disease, the spinocerebellar ataxias type 1, 3 and 17, neuroacanthocytosis, dentatorubral-pallidoluysian atrophy (DRPLA), brain iron accumulation disorders, Wilson's disease, benign hereditary chorea, Friedreich's ataxia, mitochondrial disease and Rett syndrome.
* [[PANDAS]]
 
=== Acquired causes[edit] ===
The most common acquired causes of chorea are cerebrovascular disease and, in the developing world, HIV infection—usually through its association with cryptococcal disease.
 
Sydenham's chorea occurs as a complication of streptococcal infection. Twenty percent (20%) of children and adolescents with rheumatic fever develop Sydenham's chorea as a complication. It is increasingly rare, which may be partially due to penicillin, improved social conditions, and/or a natural reduction in the bacteria (Streptococcus) it has stemmed from. Psychological symptoms may precede or accompany this acquired chorea and may be relapsing and remitting. The broader spectrum of paediatric autoimmune neuropsychiatric disorders associated with streptococcal infection can cause chorea and are collectively referred to as PANDAS.
 
Chorea gravidarum refers to choreic symptoms that occur during pregnancy. If left untreated, the disease resolves in 30% of patients before delivery but, in the other 70%, it persists. The symptoms then progressively disappear in the next few days following the delivery.
 
Chorea may also be caused by drugs (commonly levodopa, anti-convulsants and anti-psychotics).
 
Other acquired causes include CSF leak, systemic lupus erythematosus, antiphospholipid syndrome, kappa light-chain monoclonal gammopathy of undetermined significance, thyrotoxicosis, polycythaemia rubra vera, transmissible spongiform encephalopathies and coeliac disease.

Historically, choreas like Huntington disease and [[Sydenham's chorea entities|Sydenham's chorea]] were called Saint Vitus' dance, related to a series of social phenomena of the same name.

Clinic

  • It is an Entity belonged to Hyperkinetic movement / Dyskinesia's entities.
  • Also named Bizzar movements
  • Hemichorea / Hemiballismus refers to one-side chorea
  • Basal ganglion disease


Characteristics

Chorea is characterized by brief, semi-directed, irregular movements that are

  • Not repetitive
  • Not rhythmic
  • Flow from one muscle to the next.
  • Dance-like movements of chorea often occur with athetosis, which adds twisting and writhing movements.
  • Walking may become difficult, and include odd postures and leg movements.


Related entities

  • Athetosis
  • Tremor
  • Jerking / Twitching
  • Clonous
  • Fasciculation
  • Myoclonus
  • Unlike ataxia, which affects the quality of voluntary movements, Chorea is done involuntary
  • Unlike Parkinsonism, which is a hindrance of voluntary movements, the movements of Chorea / Ballism occur on their own, without conscious effort.
  • Seizure
  • Balism: When chorea is serious, slight movements will become thrashing motions; this form of severe chorea is referred to as ballism, or ballismus
  • Hyper reflexia
