Investigating markers in children with sudden-onset neuropsychiatric symptoms

Neurobiologic, Immunologic, and Rheumatologic Markers in Youth With PANS

Observational Stanford University · NCT02889016

This study is testing if certain biological markers in children with sudden neuropsychiatric symptoms can help us understand Pediatric Acute-Onset Neuropsychiatric Syndrome (PANS) better.

What this trial studies

This observational study aims to explore the neurologic, immunologic, and rheumatologic markers in children diagnosed with Pediatric Acute-Onset Neuropsychiatric Syndrome (PANS). The study will recruit 500 children aged 1-18 who have experienced a recent onset of PANS symptoms, and these participants will be compared to 100 healthy age- and gender-matched controls. By examining various biological components, the research seeks to uncover underlying mechanisms associated with PANS, which may be triggered by infections or inflammation. The findings could provide insights into the condition and inform future treatment strategies.

Who should consider this trial

Good fit: Ideal candidates are children aged 1-18 who have recently been diagnosed with PANS and live within 90 miles of Stanford University.

Not a fit: Patients with other neuropsychiatric illnesses that could complicate the diagnosis of PANS may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to a better understanding of PANS and improve diagnostic and treatment approaches for affected children.

How similar studies have performed: While this study explores a specific aspect of PANS, similar studies have shown promise in understanding autoimmune and neuropsychiatric disorders, indicating potential for success.
