PEDI Pediatric Autoimmune Neuropsychiatric Disorder Associated With Streptococcus Study

The objective of the Pediatric Epidemiological Data and Incidence (PEDI) PANDAS study is to demonstrate the feasibility of enrollment and retention of subjects in a study to determine the incidence and natural history of children with Pediatric Acute-Onset Neuropsychiatric Syndrome (PANS) with regard to spectrum, course and outcome. The investigators aim to demonstrate they can recruit and retain 85% of children who are eligible for this study. Eligible children are those who fit criteria for PANS and Pediatric Autoimmune Neuropsychiatric Disorder Associated with Streptococcus (PANDAS). Each child will be followed for one year.
