Abstract

 Sydenham's chorea (SC) is a major manifestation of rheumatic fever, and the production of anti-basal ganglia antibodies (ABGA) has been proposed in SC. The pathogenesis is hypothesized as autoimmune targeting of the basal ganglia via molecular mimicry, triggered by streptococcal infection. The spectrum of diseases in which ABGA may be involved has been broadened to include other extrapyramidal movement disorders, such as tics, dystonia, and Parkinsonism, as well as other psychiatric disorders. The autoimmune hypothesis in the presence and absence of ABGA has been suggested in Tourette's syndrome (TS), early onset obsessive-compulsive disorders (OCD), and pediatric autoimmune neuropsychiatric disorders associated with streptococcal infections (PANDAS). Recently, the relationship between ABGA and dopamine neurons in the basal ganglia has been examined, and autoantibodies against dopamine receptors were detected in the sera from patients with basal ganglia encephalitis. In Japan, the occurrence of subacute encephalitis, where patients suffer from episodes of altered behavior and involuntary movements, has increased. Immune-modulating treatments are effective, indicating the involvement of an autoimmune mechanism. We aimed to detect the anti-neuronal autoantibodies in such encephalitis, using immunohistochemical assessment of patient sera. The sera from patients showing involuntary movements had immunoreactivity for basal ganglia neurons. Further epitopes for ABGA will be investigated in basal ganglia disorders other than SC, TS, OCD, and PANDAS.
