Sydenham's Chorea
Sydenham's CholeraChorea, also known as St. Vitus Dance, is a neurological disorder characterized by rapid, uncoordinated movements primarily affecting the face, hands, and feet. This condition is a result of rheumatic fever, a complication of untreated streptococcal throat infection. Understanding the symptoms, causes, diagnosis, and treatment of Sydenham's Cholera is crucial for managing this complex disorder.
What is Sydenham's Chorea?
Sydenham's ChoreaCholera is a movement disorder caused by inflammation in the brain following a streptococcal infection. It predominantly affects children and adolescents, particularly girls, between the ages of 5 and 15. The condition is named after Thomas Sydenham, a British physician who first described it in the 17th century.

Get A Second OpinionCauses of Sydenham's Chorea
The primary cause of Sydenham's Chorea is rheumatic fever, a complication arising from an untreated or inadequately treated group A streptococcal infection, commonly known as strep throat. The condition occurs when the body's immune response to the infection mistakenly targets the basal ganglia, a group of nuclei in the brain responsible for movement control, leading to the characteristic symptoms of Chorea.
Sydenham's Chorea Symptoms
The symptoms of Sydenham's Chorea can vary in severity and may include:
- Involuntary Movements: Rapid, irregular, and uncoordinated movements, especially in the face, arms, and legs, are hallmark symptoms. These movements can interfere with daily activities, such as writing and eating.
- Emotional Instability: Patients may experience mood swings, irritability, and emotional outbursts, which are often exacerbated by stress.
- Muscle Weakness and Hypotonia: A reduction in muscle tone and strength can be observed, leading to difficulties in maintaining posture.
- Speech Impairments: Slurred speech and difficulty in articulating words may occur due to the involvement of facial muscles.
- Behavioural Changes: Anxiety, obsessive-compulsive behaviours, and attention deficits are common in individuals with Sydenham's Chorea.
Sydenham's Chorea Diagnosis
Diagnosing Sydenham's Chorea involves a comprehensive clinical evaluation and a review of the patient's medical history. Vital diagnostic criteria include:
- Clinical Examination: Observation of the characteristic involuntary movements and muscle weakness.
- Medical History: A history of recent streptococcal infection or rheumatic fever is crucial for diagnosis.
- Laboratory Tests: Blood tests to detect streptococcal antibodies, such as the antistreptolysin O (ASO) titer, may support the diagnosis.
- Neuroimaging: MRI or CT scans may be performed to rule out other neurological disorders and assess the extent of inflammation in the brain.

Book an AppointmentTreatment for Sydenham's Chorea
The treatment for Sydenham's Chorea focuses on managing symptoms and addressing the underlying cause. The therapeutic approach may include:
Pharmacological Interventions
- Antibiotics: To eradicate any residual streptococcal infection and prevent recurrence, a course of antibiotics such as penicillin is administered.
- Anti-inflammatory Medications: Corticosteroids may be prescribed to reduce inflammation in the brain and alleviate symptoms.
- Anticonvulsants and Neuroleptics: Medications such as valproic acid, carbamazepine, or haloperidol may be used to control involuntary movements and improve muscle coordination.
Supportive Therapies
- Physical Therapy: Tailored exercises can help improve muscle strength, coordination, and overall motor function.
- Speech Therapy: This can assist in enhancing communication skills and addressing speech impairments.
- Psychological Support: Counseling and cognitive-behavioural therapy can aid in managing emotional and behavioural challenges associated with the condition.
Long-term Management and Prognosis
The prognosis for Sydenham's Chorea is generally favourable, with most cases resolving within 3 to 6 months. However, some individuals may experience recurrent episodes or persistent symptoms. Long-term management includes:
- Regular Monitoring: Ongoing assessments by healthcare professionals to detect any recurrence or complications early.
- Preventive Antibiotics: Long-term antibiotic prophylaxis may be recommended to prevent future episodes of rheumatic fever and associated complications.
- Lifestyle Modifications: Stress reduction techniques, a balanced diet, and adequate rest can contribute to overall well-being and symptom management.
Conclusion
Sydenham's Chorea is a rare but significant complication of rheumatic fever, necessitating early diagnosis and comprehensive management. Understanding the symptoms and treatment options can empower patients and caregivers to navigate this condition effectively. Interdisciplinary collaboration among neurologists, paediatricians, and therapists is essential to optimize outcomes and enhance the quality of life for those affected by Sydenham's Chorea.
For more information and support, consult with healthcare professionals specializing in movement disorders or pediatric neurology. Early intervention and tailored treatment plans can significantly improve the prognosis and help individuals lead fulfilling lives despite the challenges posed by Sydenham's Chorea.
