Introduction[edit | edit source]

The word Chorea has Greek origins meaning "to dance". It has a dance-like appearance due to the random and flowing quality of the movement. Chorea is a type of hyperkinetic movement disorder. The involuntary movements flow from one body area to another which cannot be predicted beforehand.

Causes[edit | edit source]

They are predominantly of 2 types

  • Acquired Causes
  • Genetic Causes
Acquired Causes of Chorea


Genetic Causes of Chorea


Phenomenological Features[edit | edit source]

  • Randomness
  • Flowing Quality
  • Parakinesia-Patients blend their chorea induced movements with their own normal movements.
  • Motor impersistence- patient is unable to perform sustained motor activities.
  • Ballism- Variant of chorea which shows large-amplitude flinging movements involving proximal extremities.
  • Athetosis-Slow writhing movements involving distal limbs sometimes may be face.
  • Varying velocity of movements-quick velocity and low- amplitude movements accompanied by jerks.

This video displays the dance-like movements performed by a patient.
