There was a recent article in JAMA from the NIH group regarding this.
Specifically, they looked at kids with Sydenham's chorea (a post-
streptococcal disord in whom a high percentage are left
with OCD symptoms.  I think the bigger picture is that OCD may be
a disease of the cortical-subcortical circuits including the
basal ganglia.
