Sydenham Chorea
Sydenham chorea, also known as St. Vitus` dance, is a neurological disorder that is often associated with rheumatic fever. It usually affects children, especially between the ages of 5 and 15. The condition is characterized by involuntary movements of the limbs, face, and trunk, as well as muscle weakness and loss of coordination. It can also cause emotional disturbances, such as mood swings and uncontrolled outbursts of laughter or crying. The exact cause of Sydenham chorea is not yet fully understood, but it is believed to be caused by an autoimmune response triggered by a streptococcal infection. Treatment for Sydenham chorea usually involves the use of medications to reduce or control symptoms, as well as physical therapy to improve muscle strength and coordination. With proper treatment, most people with Sydenham chorea can experience significant improvement in their symptoms, although some may experience residual effects.
Symptoms of Sydenham Chorea
What are the common symptoms of Sydenham Chorea?
The common symptoms of Sydenham Chorea include involuntary movements of the arms, legs, and face, slurred speech, muscle weakness, and emotional instability. These symptoms typically worsen during periods of stress and anxiety.
What causes Sydenham Chorea?
Sydenham Chorea is caused by an autoimmune reaction to group A Streptococcus bacteria, which can occur after a person has had strep throat or another bacterial infection. The immune system mistakenly attacks the body`s own tissues, specifically the part of the brain that controls movement, leading to the characteristic symptoms of Sydenham Chorea.
How does Sydenham Chorea affect the body?
Sydenham Chorea affects the body by causing involuntary movements and weakened muscle control. These movements can be mild or severe and can interfere with daily activities such as walking, writing, and speaking. Emotional instability and cognitive impairment may also occur in some cases.
Are there any triggers that can worsen Sydenham Chorea symptoms?
Stress, anxiety, and other emotional triggers can worsen the symptoms of Sydenham Chorea. Certain medications and drugs, such as dopamine antagonists and cocaine, can also exacerbate the condition.
Is there a genetic component to the development of Sydenham Chorea?
There is a genetic component to the development of Sydenham Chorea, as certain genes have been identified that may contribute to the susceptibility to the autoimmune reaction that causes the condition. However, environmental factors such as bacterial infections are also required for the condition to develop. Source: Mayo Clinic.
Diagnosis of Sydenham Chorea
What tests are typically conducted to diagnose Sydenham Chorea?
The diagnosis of Sydenham Chorea is usually based on clinical findings and medical history. However, there are several tests that a doctor may use to further support their diagnosis. These tests include blood tests to rule out other causes of the symptoms, such as rheumatic fever, antistreptolysin O (ASO) titer tests to detect streptococcal infection, and electroencephalography (EEG) to measure brain waves and detect any abnormalities. Additionally, other tests such as magnetic resonance imaging (MRI) or computerized tomography (CT) scans can help rule out other neurological disorders that may present similar symptoms.
Is a physical examination critical in diagnosing Sydenham Chorea?
A physical examination is critical in diagnosing Sydenham Chorea as this helps the doctor to assess the severity and type of the patient`s symptoms. Through a comprehensive physical examination, a doctor can check for any difficulty in movements, gait abnormalities, muscle weakness, and coordination problems that are characteristic of Sydenham Chorea. Additionally, the doctor may assess the patient`s cognitive abilities, as this disease can also cause cognitive impairment.
Can laboratory tests provide a definitive diagnosis for Sydenham Chorea?
Laboratory tests alone cannot provide a definitive diagnosis of Sydenham Chorea. However, these tests can help to rule out other possible causes of the patient`s symptoms. For example, a positive result on an ASO titer test or increased levels of C-reactive protein (CRP) may indicate that the patient has had a recent bacterial infection, such as streptococcal pharyngitis, which is commonly associated with Sydenham Chorea.
What imaging tests are useful for diagnosing Sydenham Chorea?
Imaging tests like MRI or CT scans can be useful for detecting any brain abnormalities that may be associated with Sydenham Chorea or ruling out other neurological disorders. However, these tests are not necessary for diagnosing Sydenham Chorea and are only used when the diagnosis is not clear from clinical examination and history.
How long does it typically take to receive a diagnosis of Sydenham Chorea?
The time it takes to receive a diagnosis of Sydenham Chorea may vary depending on several factors, such as the severity of the symptoms and the patient`s medical history. A comprehensive physical examination and medical history can help the doctor to arrive at an initial diagnosis. However, further tests, such as ASO titer tests and EEG, may be needed to support the diagnosis. In some instances, an MRI or CT scan may also be required. In general, diagnosis of Sydenham Chorea takes several days to weeks, depending on the complexity of the case.
Treatments of Sydenham Chorea
What are the common medications used in the management of Sydenham Chorea?
The common medications used in the management of Sydenham Chorea are typically aimed at alleviating the symptoms and controlling inflammation. Antiepileptic drugs such as carbamazepine, valproate, phenytoin, and primidone are commonly used to control motor symptoms. Antibiotics like penicillin are administered to prevent further streptococcal infections. In severe cases, corticosteroids and immunoglobulin therapy may be prescribed.
How often should patients with Sydenham Chorea be monitored for disease progression?
What supportive therapies can be used as part of the treatment regimen for Sydenham Chorea?
Patients with Sydenham Chorea should be monitored regularly for disease progression, especially during the first few months of diagnosis. After the initial phase, patients should be reviewed by a specialist every 3-6 months or as directed by their doctor. The interval between appointments may be extended to yearly after the patient stabilizes. The frequency of monitoring may vary depending on the severity and duration of symptoms, associated risk factors, and comorbidities.
Are there any surgical options available for Sydenham Chorea treatment?

Can psychotherapy and behavioral interventions be helpful for individuals with Sydenham Chorea?
Supportive therapies that can be used as part of the treatment regimen for Sydenham Chorea include physiotherapy, occupational therapy, speech therapy, and nutritional therapy. Physiotherapy is aimed at improving motor coordination and balance, while occupational therapy helps with activities of daily living. Speech therapy is used to improve communication skills and swallow function. Nutritional therapy focuses on a well-balanced diet to promote overall health and brain function.
Prognosis of Sydenham Chorea
What is the usual duration of Sydenham Chorea?
Sydenham Chorea, also known as St. Vitus` Dance, typically lasts for several months or up to a year. However, in some cases, it may persist for longer, particularly in those with severe symptoms.
How likely is a full recovery from Sydenham Chorea?
The majority of individuals with Sydenham Chorea will experience a full recovery, with symptoms gradually fading away over time. However, a small percentage may continue to experience involuntary movements or other symptoms long-term.
Does Sydenham Chorea have an impact on life expectancy?
Sydenham Chorea itself is not typically associated with a reduced life expectancy, and most individuals will go on to lead healthy, normal lives following recovery.
What are the factors that affect the prognosis of Sydenham Chorea?
Factors that can impact the prognosis of Sydenham Chorea include the severity and duration of symptoms, the age of onset, the presence of other neurological or psychiatric conditions, and the individual`s response to treatment.
Can Sydenham Chorea lead to long-term complications?
In rare cases, Sydenham Chorea can lead to long-term complications such as recurrent episodes of chorea, other movement disorders, or psychiatric conditions such as obsessive-compulsive disorder. However, these are typically only seen in a small percentage of individuals and can often be managed with appropriate treatment.
Prevention of Sydenham Chorea
What are the most effective prevention measures for Sydenham Chorea?
The most effective prevention measures for Sydenham Chorea include early treatment of streptococcal infections with antibiotics, particularly penicillin or amoxicillin. In addition, prompt treatment of any streptococcal throat infections, as well as regular hand washing habits, can help prevent the spread of streptococcal bacteria that can cause Sydenham Chorea.
How can Sydenham Chorea be prevented in children?
Sydenham Chorea can be prevented in children by following the same prevention measures as for adults. This includes getting prompt treatment for any streptococcal throat infections or other infections, as well as practicing good hand washing habits to prevent the spread of bacteria.
What role do vaccines play in preventing Sydenham Chorea?
Vaccines do not play a direct role in preventing Sydenham Chorea, as the condition is caused by an immune response to streptococcal infections rather than the infections themselves. However, vaccines for other conditions such as influenza and pneumonia may help prevent infections that could trigger Sydenham Chorea in susceptible individuals.
Are there any lifestyle changes that can help prevent Sydenham Chorea?
While there are no specific lifestyle changes that can prevent Sydenham Chorea, practicing good hygiene and avoiding exposure to streptococcal bacteria can help reduce the risk of developing streptococcal infections that can trigger the condition.
What proactive steps can be taken to avoid developing Sydenham Chorea?
Proactive steps that can be taken to avoid developing Sydenham Chorea include early treatment of any streptococcal infections, good hand washing habits to prevent the spread of infection, and avoiding contact with others who have streptococcal infections. It is also important to seek prompt medical attention if any symptoms of Sydenham Chorea develop, such as abnormal movements, to receive timely treatment and prevent complications.
