Clinical Information
  • A group of diseases marked by involuntary and jerky movements
  • A neurological condition affecting the involuntary movements. It is characterized by brief, non-repetitive irregular muscle contractions. It is seen in patients with huntington's disease.
  • Ceaseless occurrence of rapid, highly complex jerky movements that appear to be well coordinated but are performed involuntarily.
  • Involuntary, forcible, rapid, jerky movements that may be subtle or become confluent, markedly altering normal patterns of movement. Hypotonia and pendular reflexes are often associated. Conditions which feature recurrent or persistent episodes of chorea as a primary manifestation of disease are referred to as choreatic disorders. Chorea is also a frequent manifestation of basal ganglia diseases.
