Untangling PANDAS & PANS: Conversations about Infection-Associated, Immune-Mediated Neuropsychiatric Disorders
Hello and welcome to Untangling PANDAS & PANS, a podcast about two relatively unknown medical disorders characterized by the sudden and dramatic onset of obsessions and compulsions, vocal or motor tics, or restricted eating behavior -- and a whole host of other symptoms -- following strep or other bacterial or viral infection. Sometimes overnight. I have the privilege of interviewing some of the top researchers and clinicians in the rapidly growing field of Infection-Associated, Immune-Mediated Neuropsychiatric Disorders. That’s a mouthful of words that encompasses the strangely named disorders, PANDAS and PANS.
My name is Dr. Susan Manfull. I am a social psychologist, the Executive Director of The Alex Manfull Fund, and the mother of Alex Manfull, who died at 26 years old due to PANDAS, a neuropsychiatric disorder my husband and I knew next to nothing about, certainly not that our daughter could die from it.
PANDAS is an acronym for “Pediatric Autoimmune Neuropsychiatric Disorder Associated with Streptococcus.” This disorder, first defined in 1998 at the National Institute of Mental Health, describes the acute and dramatic onset of obsessions and compulsions and/or motor or vocal tics as well as a whole host of neuropsychiatric symptoms in temporal association to a Group A streptococcal infection. PANS, which stands for Pediatric Acute-onset Neuropsychiatric Syndrome, refers to a similar symptom presentation -- with obsessions and compulsions or restricted eating being the cardinal symptoms -- due to a broader category of triggers (typically bacterial or viral infections). Both are thought to stem from a dysregulated immune system, probably leading to an over-production of autoantibodies and concomitant excess brain inflammation, particularly in the basal ganglia.
Symptoms vary from person to person and range in severity from mild to severe, and generally have a relapsing and remitting course. With early recognition and correct treatment, these disorders can be successfully treated. Today, it is no longer viewed as a diagnosis limited to the pediatric population.

S2 E19: Rheumatic Clues To Understanding the PANDAS/PANS Puzzle -- A Conversation with Dr. J. Patrick Whelan
A sore throat that ends in compulsions, tics, and a child who suddenly can’t sleep or attend school sounds improbable—until you hear a pediatric rheumatologist walk through the biology. Dr. J. Patrick Whelan of UCLA sits down with Dr. Susan Manfull, Executive Director of The Alex Manfull Fund, to unpack how infections and the immune system can collide with brain function, producing abrupt-onset OCD, motor and vocal tics, restricted eating, and anxiety that look psychiatric but respond to immunomodulatory treatments. Drawing from a variety of sources, including the history of rheumatic fever, the Lancefield classification of streptococci, and modern cases of Multisystem Inflammatory Syndrome in Children (MIS-C). Dr. Whelan explains why PANDAS and PANS challenge old categories and demand a broader clinical lens.
We dive into innate versus adaptive immunity, what “autoinflammatory” and “autoimmune” really mean, and why so many affected kids also show signs of immunodeficiency. If routine tests like ASO and anti–DNase B come back normal, does that rule out strep’s role? Not necessarily. Whelan shares how expanded antibody panels, trial responses to antibiotics or anti-inflammatories, and careful history-taking can reveal an immune trigger that standard workups miss. He also outlines the practical steps that matter right now: restore sleep, get moving, stabilize nutrition, and build companionship—simple interventions that reduce pain amplification and calm a dysregulated nervous system. Finally, we talk about why “listening to the patient” often illuminates key clues to understanding the case.
If you care about pediatric mental health, infection-associated neuroimmune disorders, or how medicine evolves when data and curiosity meet, you’ll find both science and solace here.
If this resonates, follow the show, share with someone who needs it, and leave a review to help more families and clinicians find these insights.
