AbstractSydenham's chorea is currently recognized as the only neurologic sequela of rheumatic fever. Recent evidence suggests that there may be a spectrum of neurobehavioral disturbances, particularly including tics and obsessive-compulsive disorder, that develops following streptococcal infection by the process of molecular mimicry, whereby antibodies directed against bacterial antigens cross-react with brain targets. This proposed postinfectious, immune-mediated condition has been termed “pediatric autoimmune neuropsychiatric disorders after streptococcal infection” (PANDAS). This article reviews research evidence in favor and also against the PANDAS concept and discusses the implications of the hypothesis.

AbstractBackgroundCompulsive behaviors in obsessive-compulsive disorder (OCD) have been related to impairment within the associative cortical-striatal system connecting the caudate and prefrontal cortex that underlies consciously-controlled goal-directed learning and behavior. However, little is known whether this impairment may serve as a biomarker for vulnerability to OCD.MethodsUsing resting-state functional magnetic resonance imaging (fMRI), we employed Granger causality analysis (GCA) to measure effective connectivity (EC) in previously validated striatal sub-regions, including the caudate, putamen, and the nucleus accumbens, in 35 OCD patients, 35 unaffected first-degree relatives and 35 matched healthy controls.ResultsBoth OCD patients and their first-degree relatives showed greater EC than controls between the left caudate and the orbital frontal cortex (OFC). Both OCD patients and their first-degree relatives showed lower EC than controls between the left caudate and lateral prefrontal cortex. These results are consistent with findings from task-related fMRI studies which found impairment in the goal-directed system in OCD patients.ConclusionsThe same changes in EC were present in both OCD patients and their unaffected first-degree relatives suggest that impairment in the goal-directed learning system may be a biomarker for OCD.
