PANS/PANDAS: The Testing and Treatment Options You May Not Know About

When OCD, anxiety, or food restriction appears overnight in a child, that’s a different clinical problem—and it requires a different lens.In this episode, we sit down with Dr. Lindsey Wells to walk through how to recognize and approach PANS and PANDAS in practice. We focus on the hallmark presentation: abrupt-onset neuropsychiatric symptoms, often with a clear “before and after” that families can describe in detail. From there, the conversation shifts to what may be driving that change—whether that’s infection, immune activation, inflammation, or broader system vulnerability.We also get practical. What does an initial workup look like? How do you think about common triggers like strep or other infections? When do you stay with foundational labs versus expanding further? And how do you support families who are often dealing with a sudden and destabilizing shift in their child’s behavior?This episode is for clinicians who want a clearer, more grounded way to recognize PANS and PANDAS—and to start thinking through these cases without overcomplicating or overinterpreting limited evidence.Clinical Highlights: PANS/PANDASAbrupt-Onset OCD in Children: Sudden onset OCD, food restriction, or severe anxiety should immediately shift your differential toward PANS/PANDASClinical Diagnosis Over Lab Reliance: There is no confirmatory test—history, timing, and symptom clustering drive diagnosis (AAP, 2025)Infection–Immune Connection: PANDAS is associated with streptococcal infection, while PANS includes broader potential triggers (Swedo et al., 1998; AAP, 2025)Practical Lab Workup: Foundational labs (CBC, inflammatory markers, autoimmune screening, nutrients) can help inform clinical direction (Vitiello, 2026)Relapsing–Remitting Course: These conditions often follow a flare-based pattern, requiring longitudinal care planning (Johnson et al., 2019)Guest IntroductionDr. Lindsey Wells is a naturopathic physician specializing in pediatric PANS and PANDAS. Her clinical work focuses on identifying potential infectious and immune contributors to abrupt-onset neuropsychiatric symptoms while supporting long-term stabilization. She is also the author of Super Sam and the Battle Against PANS/PANDAS, a children’s book designed to help families, siblings, and educators better understand these conditions.FAQWhat is PANS? PANS (Pediatric Acute-onset Neuropsychiatric Syndrome) is defined by the sudden onset of OCD or severe food restriction, along with at least two additional neuropsychiatric symptoms such as anxiety, regression, tics, sleep disruption, or urinary changes. It is a clinical diagnosis without a disease-specific biomarker (AAP, 2025).What is PANDAS? PANDAS is a subset of PANS associated with group A streptococcal infection, characterized by abrupt-onset OCD and/or tics with a relapsing-remitting course linked to infection (Swedo et al., 1998).What causes sudden OCD in children? In some cases, abrupt-onset OCD may be associated with post-infectious immune activation or neuroinflammatory processes, although mechanisms remain under investigation (Snider & Swedo, 2004).How is PANS diagnosed? PANS is diagnosed clinically based on symptom onset, pattern, and exclusion of other neurologic or psychiatric conditions. Laboratory testing supports—bu
