Chorea is a neurological symptom that originates in an area of the brain called basal ganglia, which are collections of nerve cells deep inside the brain that control movement.
Are movement disorders neurological?
The term “movement disorders” refers to a group of nervous system (neurological) conditions that cause abnormal increased movements, which may be voluntary or involuntary. Movement disorders can also cause reduced or slow movements.
Is chorea an autoimmune disease?
Sydenham chorea is believed to be an autoimmune disorder. Most cases develop following a streptococcal infection or more severe rheumatic fever. An autoimmune disorder occurs when the body’s immune system mistakenly reacts against healthy tissue.
What is chorea neurology?
Neurology. Chorea (or choreia, occasionally) is an abnormal involuntary movement disorder, one of a group of neurological disorders called dyskinesias. The term chorea is derived from the Ancient Greek: χορεία (“dance”; see choreia), as the quick movements of the feet or hands are comparable to dancing.Can chorea be treated?
There is no standard course of treatment for chorea. Treatment depends on the type of chorea and the associated disease. Treatment for Huntington’s disease is supportive, while treatment for Sydenham’s chorea usually involves antibiotic drugs to treat the infection, followed by drug therapy to prevent recurrence.

What is the difference between chorea and dystonia?
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.Is chorea related to Parkinson's disease?
Chorea is a common symptom of Huntington’s disease and other less-common diseases. Chorea is also frequently observed in patients with Parkinson’s disease taking a medication called levodopa. In this case, it is referred to as “dyskinesias.”
What part of the brain is affected in chorea?Chorea and athetosis result from overactivity in the basal ganglia, the part of the brain that helps initiate and smooth out and coordinate intended (voluntary) movements initiated by nerve impulses from the brain.
Article first time published onCan anxiety cause chorea?
Chorea is usually worsened by anxiety and stress and subsides during sleep. Most patients attempt to disguise chorea by incorporating it into a purposeful activity.
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.
Is Huntington's chorea the same as Huntington's disease?
Over time, it became known as “Huntington’s chorea” but because not everyone who suffers from the condition experiences chorea, the name was changed to “Huntington’s disease.”
When does chorea occur?
It affects girls more often than boys and typically occurs between 5 and 15 years of age. Some children will have a sore throat several weeks before the symptoms begin, but the disorder can also strike up to 6 months after the fever or infection has cleared.
What does mild chorea look like?
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. Overall, chorea can affect various body parts, and interfere with speech, swallowing, posture and gait, and disappears in sleep.
Does chorea hurt?
Chorea movements can be fast or slow. A person may appear to be writhing in pain and have no bodily control. These movements have also been called dance-like or similar to piano playing.

What is the difference between a neurologist and a movement disorder specialist?
A neurologist may treat patients with any of more than 100 neurological conditions, including PD. A movement disorder specialist focuses primarily on PD and movement disorders, such as dystonia and tremors.
What is the most common movement disorder?
Essential tremor (ET) is the most common adult movement disorder, as much as 20 times more prevalent than Parkinson’s disease.
What is motor dysfunction?
Motor dysfunction is a complex interaction of brain injury location, developmental plastic adaptation, and multiple physical factors over time such as weakness, dexterity, tone, musculoskeletal issues, and factors inherent to the individual child.
How do you know if you have chorea?
- Involuntary jerking or writhing movements (chorea)
- Muscle problems, such as rigidity or muscle contracture (dystonia)
- Slow or abnormal eye movements.
- Impaired gait, posture and balance.
- Difficulty with speech or swallowing.
How do you treat Sydenham's chorea?
There is no specific treatment for Sydenham’s chorea and symptoms usually resolve themselves in approximately 3 to 6 months. Bed rest, sedatives and medication to control movements may be prescribed. Penicillin prophylaxis may also be prescribed to avoid further streptococcal infection.
What is the difference between myoclonus and chorea?
Myoclonus and chorea are hyperkinetic movement disorders that confer a jerky appearance. Myoclonus involves a quick and simple jerk, whereas the jerking in chorea combines with other, slower movements in a continuous, flowing fashion.
What is the name of the disorder which causes chorea?
Chorea is the most common symptom of Huntington’s disease. In the United States, about 4,000 kids a year develop Sydenham chorea after having rheumatic fever. Rheumatic fever is a serious complication of untreated strep throat.
Why is there Chorea in rheumatic fever?
Sydenham chorea is caused by an infection with bacteria called group A streptococcus. This is the bacteria that cause rheumatic fever (RF) and strep throat. Group A streptococcus bacteria can react with a part of the brain called basal ganglia to cause this disorder.
What is an example of a hyperkinetic disorder?
Hyperkinetic disorders are a heterogeneous group of diseases characterized by the presence of excessive involuntary movements. Prominent examples for diseases in which these occur include Huntington’s chorea and hemiballism.
Is chorea a tremor?
Excerpt. The movement disorders include tremor, chorea, athetosis, myoclonus, and asterixis. Tremor consists of purposeless involuntary movements resulting from the alternating contractions of opposing muscle groups. Tremor at rest occurs when muscles are at rest, for example, the pill-rolling tremor of parkinsonism.
What is senile chorea?
Abstract. The term “senile chorea” is applied to cases of sporadic chorea with onset after the age of 50 years. The causes of senile chorea are numerous and include drugs, medications, cerebrovascular disease, genetic and sporadic neurodegenerations, and a range of systemic (hematological, metabolic, immune) disorders.
Where is the lesion in chorea?
The most consistent biochemical lesion in patients with Huntington chorea appears to be a loss of neurons in the basal ganglia that synthesize and contain GABA.
