Causes
Sydenham's Chorea is typically caused by a bacterial infection called Streptococcus pyogenes, which can also cause strep throat and scarlet fever. The infection triggers an immune response in the brain, leading to inflammation and damage to the basal ganglia, a part of the brain responsible for controlling movement.
Symptoms
The main symptom of SD is involuntary, jerky, purposeless movements that affect the face, limbs, and trunk. Other symptoms may include:
- Facial grimacing
- Tongue thrusting
- Gait disturbances
- Difficulty with speech and swallowing
- Emotional lability
Diagnosis
Diagnosing SD involves a physical examination, medical history, and blood tests to confirm a recent Streptococcus infection. Imaging tests, such as MRI or CT scans, may be used to rule out other potential causes of the symptoms.
Treatment
Treatment for SD aims to suppress the involuntary movements and prevent complications. It may include:
- Antibiotics to treat the underlying infection
- Corticosteroids to reduce inflammation
- Antipsychotics to control involuntary movements
- Physical therapy to improve coordination and mobility
Prognosis
The prognosis for SD is generally good, with most patients recovering within a few months. However, some cases may be more severe and prolonged, leading to long-term disability.
