Answer

The primary evidence for poststreptococcal autoimmune central nervous system (CNS) disease is provided by studies of Sydenham chorea, the neurologic manifestation of rheumatic fever. Reports of obsessive-compulsive disorder (OCD), tic disorders, and other neuropsychiatric symptoms occurring in association with group A beta-hemolytic streptococcal infections suggest that various CNS sequelae may be triggered by poststreptococcal autoimmunity.
