Section One

The explanation no one has given you yet.

If you’re reading this guide, it’s likely because someone you love is struggling β€” and you suspect something physiological is happening, but no one in the conventional system has been willing to look for it.

What PANS and PANDAS actually are

PANS β€” Pediatric Acute-onset Neuropsychiatric Syndrome β€” describes the sudden appearance of psychiatric symptoms (OCD, anxiety, tics, behavioral changes) in a child, triggered by infections, inflammatory responses, or environmental factors.

PANDAS β€” Pediatric Autoimmune Neuropsychiatric Disorder Associated with Streptococcal Infection β€” is a specific subset of PANS triggered by strep. While PANS can affect all ages, this guide focuses on children, whose presentation is distinct enough to deserve its own framework.

Here’s what’s happening physiologically: when the body’s immune response mistakenly attacks the brain, it causes inflammation and sudden-onset neuropsychiatric symptoms. These appear rapidly β€” often within days or weeks β€” because the immune system has been triggered by an infection, inflammatory process, or environmental exposure.

The Symptom Picture

The patterns that should make you investigate.

Most appear suddenly, or worsen sharply after an illness, fever, strep infection, or other immune trigger. Many parents describe the change with the same phrase: my child changed overnight.

Sudden-onset OCD or intrusive thoughts

Rituals, contamination fears, β€œstuck” thinking that appears within days or weeks and is out of character.

Rage episodes disproportionate to history

Explosive, often directed at safe adults, frequently followed by remorse or exhaustion.

Tics that come and go in waves

Vocal, motor, or both. Not always present, but often flares with infection or stress.

Handwriting deterioration

A frequently missed marker β€” writing that becomes smaller, less controlled, or unrecognizable within weeks.

Math regression or academic decline

A child who can no longer do work that was easy weeks earlier.

Separation anxiety in a secure child

Refusal to leave a parent, sleep alone, or go to school.

Sensory hypersensitivity

Clothing seams, food textures, noise, or light β€” new or sharply worsening.

Sleep dysregulation

Insomnia, night terrors, refusal to sleep alone, frequent waking.

New bedwetting when toilet-trained

In children ages 5 and up who had established dry nights.

Restricted eating (not an eating disorder)

Fear of choking or contamination driven by OCD or sensory shifts, not body image.

Emotional flooding

Meltdowns that go on for hours and seem to come from nowhere.

Family history of autoimmunity

Including parents who suspect they had Lyme but were never properly diagnosed.

A child sitting on the floor, head in hands
Does This Sound Like Your Child?

Your child changed. Not gradually, but in a way you can almost mark on a calendar.

Read This Slowly

You have been told it’s anxiety, a phase, the age, the screens. Underneath all of it, you are certain something physiological happened to them, and no one has been willing or able to look for it.

You may have already been to multiple providers. And you have likely heard some version of: β€œIt’s probably just anxiety. Let’s try an SSRI. Have you considered therapy?”

What you haven’t heard is someone say: β€œWe’re going to investigate what’s actually going on with your child.”

You May Have Been Told It’s One Of These

A different label may already be hiding the real driver.

If your child has already been diagnosed with one of the following, PANS/PANDAS may be the underlying driver that hasn’t been investigated yet.

ADHD

Sudden hyperactivity, impulsivity, or attention problems.

Autism (ASD)

Behavioral changes interpreted as autism or autism regression.

OCD

Intrusive thoughts and compulsive behaviors.

Anxiety (GAD)

Sudden, pervasive, generalized anxiety.

Depression

Emotional dysregulation, mood changes, or irritability.

ODD

Defiance, rage, or aggression.

These diagnoses aren’t necessarily wrong β€” but they often describe what you’re seeing without explaining why it happened suddenly. This is why children with PANS/PANDAS often see more than five doctors before a proper diagnosis. Each sees one piece of the puzzle and diagnoses that piece β€” without connecting it to the physiological root.

1 in 200

children may be suffering from PANS/PANDAS. That means in a typical school of 500 children, two or three likely have it β€” undiagnosed.

Section Two

Why conventional pediatrics misses this.

Pediatricians and child psychiatrists are not at fault. Most were never trained in sudden-onset neuropsychiatric illness rooted in immune dysregulation. But more than that β€” the entire system is structured to make the whole picture nearly impossible to see.

Most pediatricians don’t thoroughly investigate the infections that drive it. They may test for strep, or maybe Lyme β€” but not the full constellation: strep, Lyme, mold, mycoplasma, viruses, and co-infections that typically co-exist. Standard Lyme testing is particularly unreliable, and more sensitive testing isn’t part of standard pediatric practice.

The system is driven by specialization, not by seeing the whole person. OCD routes to a behavioral specialist. Gut issues go to a gastroenterologist. Anxiety earns an SSRI. No one asks: what if all of these symptoms are downstream of one immune or infectious driver? There is not one specialist in the traditional system equipped to handle PANS/PANDAS.

Most doctors don’t investigate toxin load, heavy metals, or mold. Many children with PANS/PANDAS carry high toxin loads because their detox pathways β€” influenced by their genes β€” don’t work well. Mold exposure is another driver conventional pediatrics almost never assesses.

Pediatricians don’t typically have access to advanced functional medicine testing. Comprehensive panels β€” dozens of Lyme and co-infection markers, mycotoxin exposure, advanced immune markers, metabolic dysfunction β€” are not available through standard pediatric care, often aren’t covered by insurance, and aren’t part of standard training.

What This Means For Your Family

You are not the problem.

The result of these structural gaps is consistent: parents end up doing the investigation themselves β€” for years β€” without the framework or testing access to actually find the answer.

You read the research. You join the support groups. You become an unpaid case manager for your own child, while still being the parent. And somewhere in that process you start to wonder if you are the problem, because no one with authority will tell you that you are not.

What you are is a parent in a system that requires credentials to be taken seriously. That is a structural problem. It is not a problem with your judgment as a parent.

Section Three

What an Arbor Health evaluation looks like.

Our pediatric evaluation is built specifically for the child who has been dismissed, partially treated, or routed into psychiatric care without a full medical workup.

Each evaluation is unique to that child. But we look broadly across multiple symptoms and systems. We don’t perform every test on every child β€” we order Lyme or mycotoxin testing, for example, when it’s clinically indicated by symptom presentation, exposure history, and your child’s unique picture.

Most importantly, the evaluation is built to identify all the drivers active in your child’s case at once. Single-driver investigations β€” β€œlet’s test for one infection,” β€œlet’s try one medication,” β€œlet’s see a psychiatrist” β€” are exactly what most families have already tried.

The pathway is also designed for children specifically. Pediatric immune systems test differently. Pediatric dosing is different. The way a protocol is sequenced, a family is supported, and a child’s developmental needs are accounted for are all different from adult care.

What We Evaluate

A whole-child workup, not a single test.

A comprehensive clinical picture

The full symptom timeline, triggers, and pattern recognition that establishes whether PANS/PANDAS is present.

Immune function & dysregulation

What the immune system is doing, not just what infections are present.

Gut & microbiome status

Frequently disrupted in children with PANS, and frequently driving symptom persistence.

Inflammatory & autoimmune markers

Systemic inflammation and anti-neuronal antibodies when clinically appropriate.

Toxin load & heavy metal burden

A driver conventional pediatrics rarely evaluates β€” many children carry high loads because detox pathways underperform.

Mycotoxin assessment

Evaluation of mold exposure, another driver we see frequently and others almost never address.

Comprehensive tick-borne testing

Advanced panels covering dozens of Lyme and co-infection markers when indicated β€” not standard unreliable tests.

Nutritional, metabolic & methylation

What the child’s biochemistry can β€” and cannot β€” handle, including genetic vulnerability.

Section Four

Why treatment is complex and multi-system.

A child’s behavior did not change because one thing went wrong. It changed because multiple factors converged β€” and each must be addressed.

Gut dysfunction β€” dysbiosis, leaky gut, and malabsorption reduce the ability to process nutrients, regulate neurotransmitters, and mount immune responses. Immune dysregulation leaves the system over- or under-responding, with the brain caught in the crossfire. Inflammatory load is high, disrupting neurotransmitter balance and triggering neuropsychiatric symptoms.

Infections β€” multiple types often co-exist, frequently missed by standard testing. Common drivers include:

  • Streptococcal infections β€” PANDAS specifically
  • Lyme & co-infections β€” Babesia, Bartonella, Ehrlichia
  • Mycoplasma and mold / mycotoxin exposure
  • Viruses β€” EBV, CMV, Coxsackie, and others

Neurological inflammation may be present, particularly in the basal ganglia, and toxin load accumulates in children whose detox pathways don’t work well. Psychiatric manifestations are real, but downstream β€” treating OCD with SSRIs alone, without addressing what generates it, is like treating a fever without investigating the infection.

Previous treatments failed not because they weren’t good. They failed because they were incomplete.

Section Five

The glass metaphor.

A glass of water overflowing

Imagine your child’s body is like a glass of water.

Infections, inflammation, gut dysfunction, immune dysregulation, toxin burden β€” they all fill the glass until it overflows. The overflow is what you see: the OCD, the rage, the tics, the meltdowns. The symptoms are the overflow.

A course of antibiotics stops the overflow temporarily. Your child improves. But here’s what’s critical: the glass is still completely full.

It takes almost nothing to make it overflow again β€” a new infection, a stressor, a sleep-disrupted week. The parent thinks treatment failed. It didn’t. The glass never actually got emptied.

Real recovery means emptying the entire glass β€” work that takes months.

1

Identify every source filling the glass

Infections, inflammatory triggers, gut dysfunction, detox issues, heavy-metal burden, metabolic imbalance, mold. Not one source β€” all of them. You cannot guess; you must test.

2

Address all the sources, in phases

Stabilization, then gut healing, immune modulation, infection treatment, detox support, nutritional restoration, nervous-system rebuilding β€” personalized, not one-size-fits-all.

3

Work at a pace the body can tolerate

You cannot dump every treatment on at once; the body cannot process that load. Each phase matters. Each phase needs time.

4

Open the detox pathways β€” the hole in the bottom

Once the glass empties and water drains instead of accumulating, your child becomes resilient. A stressor arrives, the body processes it, and the symptoms don’t return.

This is why flares happen during treatment and why retesting along the way is critical. Over time, flares become less intense, shorter, and less frequent until they basically stop. We put the condition into remission.

Section Six

Healing happens in phases.

Recovery typically unfolds across multiple phases over many months. Symptoms shift. Tolerances shift. The family’s capacity shifts. Nonlinear progress is still progress.

Investigation & mapping

Understanding what’s in the glass β€” infections present, what the immune system is doing, gut status, the inflammatory picture, what toxins are present.

Stabilization

Bringing immediate relief where possible, reducing the most acute symptoms, and beginning nervous-system support and routine.

Sequenced treatment

Gut healing, immune modulation, targeted infection treatment, detox, nutritional rebuilding β€” layered in the right order, with retesting along the way.

Restoration & resilience

Continued nervous-system regulation, emotional recovery, family-system healing, and gradual return to full function.

A treatment plan delivered in 20-minute visits with no support between cannot work β€” the plan goes stale, questions accumulate, the case stalls. What works is phased treatment with continuity: someone to call when a flare arrives, a team that helps you navigate school, and assessment before each new phase begins. This is also why parent education matters β€” parents who understand why setbacks happen sustain the work long enough for healing to occur.

Section Seven

Why our program is 12 months.

β€œCan we do this in 6 months? Can we speed this up?” The glass cannot be emptied faster than the body can safely empty it.

Many children improve significantly within the first 2–3 months β€” symptoms quiet, the overflow stops, the family becomes hopeful. But the glass is still full. Stop at month three and the baseline drifts back. Our program runs a full 12 months and we don’t pad it β€” the physiological work takes the better part of a year, and you cannot compress it without losing the depth that creates lasting recovery.

Why Early Diagnosis Matters

Your child’s recovery window is open. Waiting does not make it easier.

Left untreated, symptoms can persist or worsen into a lifelong challenge. Early diagnosis with the right approach dramatically improves outcomes. By investigating root causes and committing to the phased work now, you prevent years of unnecessary struggle.

This timeline is also why insurance cannot fund this care. Insurance is built for acute episodes β€” it approves 2–4 weeks and moves on. PANS/PANDAS requires many months of continuous, coordinated, evolving care. The system is structurally incompatible with the treatment model your child actually needs.

Section Eight

Why this requires cash-pay.

Not because we want to exclude families β€” but because insurance restrictions prevent the clinical model your child’s case requires.

It dictates which tests can be ordered. Comprehensive immune panels, advanced tick-borne testing, mycotoxin and heavy-metal evaluation, gut and metabolic workups β€” β€œmedically necessary” is often far narrower than clinical judgment requires. Drivers get missed.

It dictates which prescriptions, and for how long. PANS/PANDAS often needs extended courses; insurance approves 2–4 weeks when real healing needs 8–12 weeks or more at a given phase.

It dictates visit frequency and length. It reimburses 15-minute visits; PANS needs 60–90 minute evaluations and longer continuity visits.

It prevents the invisible labor that allows healing. Designing plans, monitoring labs, adjusting protocols, coordinating with school, and the clinical coaches we include β€” none of it is covered.

Investment In Your Child’s Recovery

$425–$697 per month

Billed monthly β€” depending on the complexity of your child’s needs and the psychiatric medication management required. This reflects the true cost of care: provider time, clinical-coach time, continuity across the full program, between-visit responsiveness, school coordination, and flare management. We make no money on functional-medicine testing β€” all testing revenue goes directly to the labs. Additional specialized panels are priced separately when clinically indicated, always with clear estimates before ordering.

Section Nine

How to evaluate any PANS/PANDAS provider.

Whether you’re evaluating Arbor Health or anyone else, ask these. The answers reveal whether they can actually do this work β€” or are operating within the same fragmented system that has failed your child so far.

On Testing Access
Do they have access to mycotoxin testing?
Advanced tick-borne testing with dozens of markers β€” not just standard tests?
Can they test the full constellation: strep, Lyme, mold, mycoplasma, and others?
On Clinical Authority
Can they independently order clinical testing?
Can they prescribe medications?
Can they prescribe psychiatric medications when indicated?
On Support Structure
Will you be assigned a clinical coach throughout your program?
Will you get rapid responses β€” typically within 24–48 hours?
What patient-education materials do they have?
On Systems Support
What kind of school support do they offer?
What parent and family support do they offer?
How do they handle flares between visits?

What our program is built for

You’re not overreacting and your child isn’t treatment-resistant β€” you’re looking at multiple unidentified drivers.

Section Eleven

Finding community & taking the next step.

Start by finding a PANS/PANDAS parent community in your area. Facebook parent groups can be enormously validating β€” you’ll find other parents describing your child, and language for what you’ve been living. For broader clinical education and provider resources, ASPIRE (aspire.care) is an excellent starting point, aggregating research, provider training, and family education across the field.

Apply For A Discovery Call

If you recognize your child, we want to hear from you.

Your application is reviewed by a trained Clinical Intake Coordinator β€” not a generic call. We’ll ask about your child’s timeline, symptom pattern, previous treatments, and your family’s readiness for a 12-month recovery process.

Section Twelve Β· Voices From Families
β€œ

Before finding Arbor Health, my son had seen more than ten doctors and none had taken a holistic approach. After a trip to Children’s Hospital of Philadelphia that left us with no answers, we were thrilled to find an expert in our own backyard. Their approach to treating PANS and Lyme has been completely on point.

β€” Keri C., Arbor Health parent

β€œ

My six-year-old has been a patient for about six months. Quality of life has improved greatly since we started treatment for PANS. Every patient is different, and they take the time to test for your child’s triggers and treat the root causes. This is the medicine we need for our families.

β€” Mandy W., Arbor Health parent

A Final Word

There is a level of recovery available to most of these children that they have never been offered the structure to reach.

You may have been told you are overreacting. That this is who your child is now. Most of that is wrong. There are patterns underneath your child’s symptoms that have not been investigated. The work is real. The time required is real. But the path forward exists.
