What is the definition for chorea?
Definition. Chorea is an abnormal involuntary movement disorder, one of a group of neurological disorders called dyskinesias, which are caused by overactivity of the neurotransmitter dopamine in the areas of the brain that control movement.
What are the different types of chorea?
Vascular.
What are the signs and symptoms of chorea?
The most common signs of chorea are:
- Involuntary muscle movements: Also called fidgety movements or dance-like movements usually appear in the hands, feet, and face.
- Milkmaid’s grip: Rather than holding your hand steady when you try to shake someone’s hand, you may grip and release your fingers over and over again.
What is chorea Ballismus?
Chorea and ballismus fall under the category of hyperkinetic movement disorders and are due to lesions of the basal ganglia. Rapid, involuntary, non-rhythmic, non-stereotypical, small amplitude movements are termed as chorea, while ballismus is a proximal chorea that produces flinging movements of high amplitude.
What can cause chorea?
What causes chorea?
- AIDS.
- genetic conditions, such as Huntington’s disease.
- immune conditions, such as systemic lupus erythematosus.
- infection-related conditions, such as Sydenham’s chorea.
- medications, including levodopa and neuroleptics.
- metabolic or endocrine disorders, including hypoglycemia.
What causes Sydenham’s chorea?
Sydenham chorea (SC) is a neurological disorder of childhood resulting from infection via Group A beta-hemolytic streptococcus (GABHS), the bacterium that causes rheumatic fever. SC is characterized by rapid, irregular, and aimless involuntary movements of the arms and legs, trunk, and facial muscles.
What is the difference between dystonia and chorea?
Dystonia is a movement disorder in which involuntary sustained or intermittent muscle contractions cause twisting and repetitive movements, abnormal postures, or both. Chorea is an ongoing random-appearing sequence of one or more discrete involuntary movements or movement fragments.
What does chorea feel like?
The most common symptom is jerky movements of the arms and legs, known as ‘chorea’. Chorea usually starts as mild twitching and gradually increases over the years. A person with Huntington’s disease may also have difficulties with speech, swallowing and concentration.

What is Sydenham’s chorea?
Definition. Sydenham chorea (SC) is a neurological disorder of childhood resulting from infection via Group A beta-hemolytic streptococcus (GABHS), the bacterium that causes rheumatic fever. SC is characterized by rapid, irregular, and aimless involuntary movements of the arms and legs, trunk, and facial muscles.
What is the difference between chorea and Ballismus?
Athetosis is a continuous stream of slow, flowing, writhing involuntary movements. It usually affects the hands and feet. Hemiballismus is a type of chorea, usually involving violent, involuntary flinging of one arm and/or one leg. Movements are wider and more intense than chorea.
What does chorea look like?
Chorea is an abnormal involuntary movement derived from the Greek word “dance”. It is characterized by brief, abrupt, irregular, unpredictable, non-stereotyped movements. In milder cases, chorea may appear purposeful. The patient often appears fidgety and clumsy.
