The research findings reported in this study challenge the dogmas regarding the immune privilege status of the central nervous system (CNS) and its isolation from the immune system by the blood-brain barrier. Functional meningeal lymphatic vessels capable of carrying immune cells and interstitial fluids from the CNS are identified and characterized. Findings provide novel understanding on how autoimmune encephalopathies, like PANS/ PANDAS, can develop when these unique lymphatic vessels malfunction.

On May 23 and 24, 2013, the First PANS Consensus Conference was convened at Stanford University, calling together a geographically diverse group of clinicians and researchers from complementary fields of pediatrics: General and developmental pediatrics, infectious diseases, immunology, rheumatology, neurology, and child psychiatry. Participants were academicians with clinical and research interests in pediatric autoimmune neuropsychiatric disorder associated with streptococcus (PANDAS) in youth, and the larger category of pediatric acute-onset neuropsychiatric syndrome (PANS). The goals were to clarify the diagnostic boundaries of PANS, to develop systematic strategies for evaluation of suspected PANS cases, and to set forth the most urgently needed studies in this field. Presented here is a consensus statement proposing recommendations for the diagnostic evaluation of youth presenting with PANS.
