Expertise in All Types of Chorea

Chorea is a movement disorder characterized by short bursts of irregular, non-rhythmic and non-repetitive contractions. Movements flow from one muscle to the next and are frequently accompanied by twisting and writhing motions.  

Huntington's disease is the most common chorea. This inherited movement disorder causes progressive degeneration of nerve cells in the brain and decreases functional abilities. Other types of chorea include:


  • Sydenham's chorea – contracted from Streptococcus bacteria. 
  • Chorea gravidarum – which can be triggered by bacteria, use of oral contraceptives or previous acute rheumatic fever that appeared during pregnancy and disappeared after delivery.
  • Chorea from other sources – such as reactions to drugs or medications, hyperthyroidism or vascular incidents such as a stroke or Wilson’s disease (an accumulation of copper in the body).

 Diagnosing & Treating Chorea

How is chorea diagnosed?

If our team suspects Huntington’s disease or chorea, we will conduct a comprehensive consultation that includes a discussion of your personal and family medical history. From there, we will perform a physical exam to rule out underlying conditions that could cause motor function deficits. Our neurologists may also order MRI or CT exams to assess your brain structure and function. 

Next, we will conduct neurological and psychiatric evaluations to assess your mental and physical functionality. During these exams, we will analyze your symptoms and watch for reactions such as:


  • Involuntary movements and muscle control deficits:
    • Involuntary jerking or writhing movements
    • Rigid or contracted muscles 
    • Slow or abnormal eye movements
    • Abnormal gait, posture and balance
    • Difficulty with speech or swallowing


  • Cognitive impairments: 
    • Difficulty in organizing or focusing on tasks
    • Tendency to get stuck on a thought, concept, behavior or action
    • Lack of impulse control 
    • Lack of self-awareness 
    • Difficulty remembering the word you want to use
    • Difficulty learning new information


  • Mood and behavioral symptoms: 
    • Alternating bouts of depression and mania
    • Irritability
    • Social withdrawal
    • Insomnia
    • Thoughts of death and suicide
    • Obsession and compulsion
