One week your child is themselves. The next, they are washing their hands raw, refusing to eat foods they have always loved, having rage episodes that come out of nowhere, or developing tics that weren’t there a month ago. For families dealing with PANS or PANDAS, the change is often that sudden and that disorienting. You feel like you are watching a stranger take up residence in your child’s body, and you cannot get a straight answer about what happened or what to do next. If this is your reality, you are not imagining it, and you are not alone.
What Are PANS and PANDAS?
PANDAS stands for Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal Infections. PANS, the broader umbrella term, stands for Pediatric Acute-onset Neuropsychiatric Syndrome. Both describe the same general phenomenon: a previously healthy child suddenly develops dramatic neuropsychiatric symptoms following an infection, environmental trigger, or immune challenge. PANDAS is specifically tied to strep, while PANS can follow viruses, Lyme disease, mycoplasma, mold exposure, and other inflammatory triggers.
The mechanism is essentially autoimmune. The child’s immune system, while fighting off the infection, produces antibodies that mistakenly cross the blood-brain barrier and attack a region of the brain called the basal ganglia. That part of the brain governs movement, mood, focus, and impulse control. When it gets inflamed, behavior changes follow. The hallmark is the speed of onset. Parents often describe it as a switch flipping overnight.
The Symptoms Many Pediatricians Miss
PANS and PANDAS are still underdiagnosed, in part because the symptoms look like so many other things. The most common signs include sudden onset OCD or intrusive thoughts, severe separation anxiety, dramatic mood swings, new motor or vocal tics, food restriction or sensory sensitivity to textures, handwriting deterioration, sleep disruption, urinary changes like new-onset bedwetting, and a regression in age-appropriate behavior.
What separates PANS and PANDAS from other conditions is the acute timeline. Parents can usually pinpoint the week, sometimes even the day, when their child changed. Many families spend months bouncing between pediatricians, therapists, and behavioral specialists before someone connects the dots. By the time a diagnosis is even considered, the family has often been told it is anxiety, defiance, or “just a phase.”
Where Functional Neurology Fits In
Standard medical care for PANS and PANDAS typically involves identifying and treating the underlying infection, reducing inflammation, and in some cases, immune-modulating therapies. Functional neurology care is not a replacement for that medical workup, but it can play an important supporting role in helping a child’s nervous system recover and reorganize once the immune storm settles.
At Restore Functional Neurology in Joplin, Dr. Carr works with families navigating PANS and PANDAS by focusing on the downstream neurological effects: a dysregulated autonomic nervous system, disrupted sensory processing, motor coordination issues, retained or re-emerged primitive reflexes, and the deep stress response that takes hold when a child’s brain has been in crisis. Through chiropractic care that supports vagal tone and nervous system regulation, vestibular and eye-tracking work to rebuild motor and sensory pathways, low-level laser therapy to address inflammation in targeted areas, and individualized exercises to integrate reflexes that may have re-emerged during the flare, the goal is to give the brain the inputs it needs to return to baseline.
You Know Your Child Better Than Anyone
If you have been told your child’s sudden change is “just anxiety” or “just behavior” and your gut is telling you something else is going on, listen to that. Parents are usually the first to recognize a PANS or PANDAS pattern, often long before the medical system catches up. Whether your child already has a diagnosis and you are looking for supportive care, or you are still trying to make sense of what is happening, we are here to help you think it through.
Reach out to Restore Functional Neurology to schedule a consultation with Dr. Carr. We will take the time to listen to your child’s full story, evaluate where their nervous system is right now, and help you build a path forward that complements the rest of their care team.
