Anti basal ganglia antibodies basal ganglia chorea. Medical search. Frequent questions

GAS M proteins share epitopes (antigenic-determinant sites that are recognized by antibodies) with proteins found in synovium, heart muscle, and heart valve, suggesting that molecular mimicry by GAS antigens from rheumatogenic strains contributes to the arthritis, carditis, and valvular damage. (merckmanuals.com)
Patients with these disorders often have antibodies to the basal ganglia in the brain, and molecular mimicry between basal ganglia and S. pyogenes-derived proteins remains the major postulated mechanism of disease induction. (jontristermd.com)

Recently there has been a decline in incidence which is probably the result of a decline in rheumatic fever (RF), which was a major cause of chorea gravidarum before the use of antibiotics for streptococcal pharyngitis. (wikipedia.org)
History of either rheumatic fever or chorea is suspected: the suggestion is that estrogens and progesterone may sensitize dopamine receptors (presumably at a striatal level) and induce chorea in individuals who are vulnerable to this complication by virtue of preexisting pathology in the basal ganglia. (wikipedia.org)
The relation to rheumatic fever was strengthened by many studies that showed that women with normal pregnancies before rheumatic fever developed chorea in subsequent pregnancies. (wikipedia.org)
