Research Links OCD and Streptococcal Infections

[摘要] There is an increasing body of data that suggests there may be relationship between certain forms of childhood-onset OCD and previous Group A beta-hemolytic streptococcal infections. They seem to have early-onset OCD, tic disorder, Sydenham's chorea and family history of tics. Sydenham's chorea, a major manifestation of rheumatic fever and a disorder generally limited to prepubertal children, is thought to be disease of basal ganglia, and the basal ganglia is thought to be involved in both Sydenham's chorea and OCD. Children with Sydenham's chorea frequently present with OCD symptoms.
