Introduction

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

They are predominantly of 2 types

• Acquired Causes
• Genetic Causes

Acquired Causes of Chorea

Genetic Causes of Chorea

Phenomenological Features

• 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.
