Managing Sydenham Chorea
Sydenham chorea, often referred to as St. Vitus' dance, is a neurological disorder characterized by rapid, uncoordinated movements affecting the face, hands, and feet. This condition predominantly affects children and adolescents and is a major clinical manifestation of acute rheumatic fever. Understanding its symptoms, diagnosis, causes, and management is crucial for effective treatment and better patient outcomes.

Get A Second OpinionWhat is Sydenham Chorea?
Sydenham chorea is an autoimmune disorder that arises as a complication of streptococcal infections, specifically Group A beta-hemolytic streptococcus. The condition is named after Thomas Sydenham, who first described it in the 17th century. It is characterized by involuntary, rapid, and irregular movements, emotional instability, and muscle weakness.
Symptoms of Sydenham Chorea
Motor Symptoms
The hallmark of Sydenham chorea is the presence of involuntary movements, particularly affecting the hands, feet, and face. These movements are jerky, rapid, and uncoordinated, making daily activities challenging. Patients may exhibit:
- Choreiform Movements: Quick, irregular, and unpredictable muscle contractions.
- Muscle Weakness: Generalized weakness and fatigue.
- Gait Disturbances: Difficulty in walking, characterized by unsteady and exaggerated movements.
Neuropsychiatric Symptoms
In addition to motor symptoms, Sydenham chorea often presents with a range of neuropsychiatric symptoms, including:
- Emotional Instability: Sudden mood swings, irritability, and episodes of crying or laughing.
- Obsessive-Compulsive Behaviors: Repetitive actions or thoughts.
- Cognitive Impairment: Difficulty in concentrating and memory issues.
Other Symptoms
- Speech Difficulties: Slurred speech and difficulty in articulating words.
- Handwriting Changes: Noticeable deterioration in handwriting quality.
Causes of Sydenham Chorea
Sydenham chorea is primarily caused by an autoimmune reaction following an infection with Group A beta-hemolytic streptococcus. The body’s immune system mistakenly attacks the basal ganglia, a region in the brain responsible for motor control, leading to the characteristic symptoms of the disorder.
Risk Factors
- Age: Most commonly affects children between the ages of 5 and 15.
- Gender: Higher incidence in females.
- History of Rheumatic Fever: Previous episodes of rheumatic fever increase the risk.
Diagnosis of Sydenham Chorea
Clinical Evaluation
Diagnosis of Sydenham chorea is primarily clinical, based on a detailed patient history and physical examination. The following criteria are considered:
- History of Streptococcal Infection: Recent throat infection or confirmed rheumatic fever.
- Neurological Examination: Assessment of involuntary movements, muscle strength, and coordination.
- Psychiatric Evaluation: Screening for emotional and cognitive symptoms.
Laboratory Tests
- Throat Culture: To identify Group A streptococcus.
- Blood Tests: Elevated levels of anti-streptolysin O (ASO) antibodies indicating a recent streptococcal infection.
Imaging Studies
- MRI and CT Scans: Although not routinely required, these imaging modalities can help rule out other neurological conditions.
Management and Treatment of Sydenham Chorea
Medical Treatment
The primary goal of treatment is to manage symptoms and prevent complications. The mainstay of treatment includes:
- Antibiotics: Long-term antibiotic prophylaxis to prevent recurrent streptococcal infections and rheumatic fever.
- Anti-inflammatory Medications: Corticosteroids or non-steroidal anti-inflammatory drugs (NSAIDs) to reduce inflammation in the brain.
- Antipsychotic Medications: Drugs like haloperidol or risperidone may be prescribed to manage severe choreiform movements and psychiatric symptoms.
Supportive Therapies
- Occupational Therapy: To assist with daily activities and improve coordination.
- Physical Therapy: To strengthen muscles and enhance motor control.
- Speech Therapy : To address speech difficulties and improve communication skills.
Lifestyle and Home Remedies
- Regular Follow-ups: Continuous monitoring by healthcare providers to adjust treatment plans as needed.
- Stress Management : Techniques such as mindfulness and relaxation exercises to manage emotional instability.
- Nutritional Support: A balanced diet to ensure adequate nutrition and energy levels.

Book an AppointmentPrognosis and Long-term Outcomes
The prognosis for Sydenham chorea is generally favorable, especially with timely diagnosis and appropriate treatment. Most patients experience significant improvement within 2 to 3 months, although some symptoms may persist longer. Recurrences can occur, particularly if preventive measures against streptococcal infections are not maintained.
Complications
- Cardiac Issues: Potential for rheumatic heart disease if associated with rheumatic fever.
- Chronic Movement Disorders: Rarely, some patients may develop persistent movement disorders.
Preventive Measures
- Prompt Treatment of Strep Throat: Early antibiotic treatment for streptococcal infections to prevent rheumatic fever.
Regular Medical Check-ups: Ongoing evaluation to detect and manage recurrences promptly.
Frequently Asked Questions
1. What causes Sydenham chorea?
Sydenham chorea is caused by a complication of rheumatic fever, where the immune system mistakenly attacks parts of the brain, leading to involuntary movements.
2. What are the symptoms of Sydenham chorea?
Symptoms include rapid, uncoordinated jerking movements, especially in the hands, feet, and face, along with muscle weakness and emotional instability.
3. How is Sydenham chorea diagnosed?
Diagnosis involves a clinical evaluation of symptoms and a history of recent streptococcal infection or rheumatic fever.
4. How is Sydenham chorea treated?
Treatment includes antibiotics to treat the underlying infection, anti-inflammatory medications, and in some cases, antiepileptic drugs to manage movements.
5. What is the prognosis for Sydenham chorea?
Most individuals recover completely, although some may experience recurring symptoms or long-term complications.
