PANDAS on the Playground
A third-grader walks into the health office—not with a skinned knee or a stomachache, but trembling with unfamiliar fears and compulsions that seemed to appear overnight. What was once a confident, easygoing student now suddenly seems gripped by panic and repetitive rituals. This rapid transformation is the hallmark of Pediatric Acute-onset Neuropsychiatric Syndrome (PANS) and its streptococcal-linked relative, Pediatric Autoimmune Neuropsychiatric Disorder Associated with Streptococcal Infections (PANDAS). These conditions blur the lines between infection and mental health, where a simple sore throat can trigger a neurological storm.
Pinning Down PANS and PANDAS
PANS is an umbrella term for the sudden appearance of obsessive-compulsive disorder (OCD) or severely restricted food intake, accompanied by at least two other neuropsychiatric symptoms such as extreme anxiety, emotional lability, or motor tics. PANDAS is a specific subset of this syndrome that occurs when a Group A Streptococcal infection triggers a misdirected immune response. In these cases, the body’s antibodies, intended to fight the bacteria, mistakenly target the basal ganglia in the brain, leading to inflammation and dramatic behavioral shifts.
Although precise prevalence is difficult to determine, current estimates suggest that PANS and PANDAS affect approximately 1 in 200 children annually. Most cases occur in pre-pubertal children between ages 3 and 13, with onset in adulthood being rare. A family history of autoimmune conditions, sometimes extending to ancestors with rheumatic fever, appears to increase susceptibility. Of particular concern in school settings are “carrier” students with asymptomatic or untreated infections that may trigger neurological inflammation. Recurrent infections, exposure to mold, and certain viral or bacterial illnesses—including influenza and mycoplasma—may further elevate risk in children whose immune systems are already primed for a misdirected response.
The School Day Snapshot
In a school setting, characteristic features of PANS or PANDAS can become apparent when key indicators are recognized. A student who previously demonstrated legible, consistent handwriting may develop dysgraphia, displaying poor letter formation, margin drift, or difficulty maintaining a pencil grasp. Recently acquired math skills may regress, leading to challenges with basic computation. Additional symptoms may include urinary frequency resembling a urinary tract infection and severe separation anxiety.
For school nurses, recognizing these abrupt changes is critical, as early observation often prompts the pathway to diagnosis and support. Collaboration with parents, teachers, and healthcare providers can help differentiate PANS or PANDAS from other behavioral or learning concerns. Documenting symptom onset, frequency, and any temporal connection to recent infections provides valuable information for clinicians.
Bridging Health & Learning
Caring for students with PANS or PANDAS requires a proactive and compassionate approach from school health staff. Individualized Healthcare Plans (IHPs) are essential, allowing for flexibility as students may experience periods of remission and relapse. Practical accommodations can make a meaningful difference—such as special bathroom passes to reduce embarrassment from frequent restroom use, offering short rest breaks in the school health office to manage fatigue, and adjusting homework and assignments to reflect temporary cognitive difficulties. Above all, school nurses can advocate for students, helping educators recognize that these behaviors stem from a medical condition rather than intentional defiance. Equipping teachers with this understanding fosters empathy, patience, and more effective support in the classroom.
Heart of the Matter
Few conditions illustrate the intersection of physical and emotional health quite like PANS and PANDAS. They remind us that a student’s well-being is never compartmentalized—it lives in every heartbeat, thought, and moment of learning. By understanding how medical and behavioral factors intertwine, school nurses ensure that care in schools remains both holistic and informed.
