Sydenham’s chorea



Characterized by rapid, jerky, irregular, and involuntary movements (especially of the face and limbs). In children, these symptoms often appear after strep throat or rheumatic fever, caused by a group A streptococcus infection. Group A streptococcus bacteria can react with a part of the brain called the basal ganglia to cause Sydenham’s chorea.

Common Symptoms

Uncoordinated movements, slurred speech stumbling, muscular weakness, tics, obsessions, compulsions, inattention, and anxiety.

Coexisting Diseases and Conditions

Attention deficit hyperactivity disorder and affective disorders, Hashimoto’s thyroiditis, systemic lupus erythematosus, and arthritis.
