How PANS and PANDAS Are Treated: A Functional Medicine Framework

Quick answer: PANS and PANDAS are treated by combining two things that work better together than apart — conventional care that finds and treats the trigger and calms an acute flare, and root-cause functional medicine that steadies the immune system so flares get less frequent and less severe. The established framework moves through five connected jobs: treat the trigger, calm the inflammation, steady the immune system, address what's driving it underneath, and support the whole child and family. No two children get the same plan, because no two children have the same triggers, labs, or history.
There's a moment I see over and over with PANS and PANDAS families. The crisis has finally been named, there's a diagnosis on paper at last — and right behind the relief comes a new kind of overwhelm. Okay. So how do we actually fix this? You've read the forums. You've seen the supplement lists that run a mile long. And you're trying to figure out where on earth to start without making your exhausted child swallow forty things a day.
So let me walk you through how treatment actually works — what the research supports, what each step is really for, and why the plan that helps your child won't look like the plan that helped someone else's. (If you're still earlier in this — wondering whether what you're seeing even is PANS or PANDAS — start with the PANS and PANDAS overview first, then come back here.)
What's actually being treated?
To treat PANS and PANDAS, you have to understand what's driving them. The leading explanation, supported by the major research consensus, is that an infection or other trigger sets off an immune response that doesn't shut off properly — and that misdirected response inflames the brain, particularly a region called the basal ganglia that helps regulate movement, emotion, and impulse control. Dr. Nancy O'Hara, a pediatrician who has spent decades treating these children and wrote one of the field's key clinical references, describes the condition as basal ganglia encephalitis — literally, inflammation of the basal ganglia. I find that framing helpful, because it names what we're really treating: not just the OCD or the tics on the surface, but the inflammation underneath them, and the things keeping it lit. In well-characterized groups of PANS patients, evidence of this kind of post-infectious immune activation shows up in the large majority of cases.
What sets it off — and why it isn't always strep
PANDAS is the version triggered by strep. PANS is the broader umbrella, and the trigger can be many things: mycoplasma (walking pneumonia), the flu, a lingering sinus infection, or other viruses. Increasingly, clinicians also recognize environmental drivers. Teresa Holler, who works extensively in this space, has helped bring attention to mold and mycotoxin exposure and to tick-borne infections — Lyme and its co-infections — as triggers and perpetuators in some children. As Dr. O'Hara puts it, genetics can load the gun and an environmental trigger pulls it. That's exactly why two children with the same strep infection can have completely different outcomes — and why finding your child's specific trigger is the whole first step.
Why one approach is rarely enough
The national treatment guidelines for PANS and PANDAS, published by the PANS/PANDAS Research Consortium, organize care around three pillars working at once: treating the infection or trigger, calming the immune and inflammatory response, and supporting the child psychiatrically and behaviorally through it. The families I work best with want all of that — and they want someone looking underneath it, asking why this child's immune system is so reactive in the first place. That's the difference between managing PANS and getting ahead of it. Here's the arc I use.
Step 1: Find and treat the trigger
You can't calm a fire while the match is still lit. The first job is to figure out what set this off and treat it — strep, another infection, or, in some children, an environmental driver like mold exposure or a tick-borne infection. This step uses the right testing to identify current or recent triggers and treats any active infection, typically with your child's pediatrician. Some children also need a plan for recurrent infections, because each new one can light things up again. Removing or treating the trigger is the foundation everything else is built on.
Step 2: Calm the inflammation
Once the trigger is addressed, the goal is to bring down the brain inflammation fast enough that your child gets real relief — and can actually participate in the rest of the plan. A child mid-flare can't do the slower, deeper work yet. This is where anti-inflammatory nutrition matters more than people expect, alongside targeted nutrients known to support a calmer immune response. For more significant flares, the guidelines also describe provider-directed anti-inflammatory medications, and the more intensive of these are co-managed with the appropriate specialists. The point of this step is simple: turn the temperature down so your child can come back to themselves.
Step 3: Steady the immune system
This is usually the longest stretch, and it's where root-cause work earns its keep. After the acute flare settles, the work shifts from putting out the fire to teaching the immune system to stop overreacting — so flares become less frequent, less severe, and easier to recover from. For most children this is a patient, layered process rather than a single intervention. A smaller number of children, with severe or treatment-resistant disease, need specialist-level immune therapies such as IVIG; those are evaluated and managed by a neuroimmunology or specialist team. I co-manage alongside that care — I don't replace it.
Step 4: Address what's driving it underneath
This is the part conventional care often doesn't have time for, and it's where I spend a lot of mine. Two children can both have PANDAS and have completely different reasons their immune systems are stuck in overdrive. So I look at what's quietly feeding the fire and build support around what your child's testing actually shows — not a generic checklist:
Gut health. So much of the immune system lives in the gut, so a reactive, inflamed gut keeps a reactive immune system company. Repairing the gut lining and rebalancing the microbiome is often foundational. (This is why gut testing for kids shows up so often in PANS work.)
Nutrient gaps. Children with PANS are frequently low in specific nutrients the brain and immune system depend on. I replenish those only when testing shows they're low — not on guesswork.
Food sensitivities. Foods that quietly add to the inflammatory load can be identified and removed.
Mast cell and histamine patterns. When an overreactive histamine response is part of the picture, calming it can make a real difference.
Environmental burden. When mold or tick-borne infections are part of the story, addressing that exposure and load is part of the plan — an area clinicians like Teresa Holler have done a lot to illuminate.
Other root contributors. Methylation, mitochondrial support, and similar pieces — addressed only when the labs point there.
Step 5: Support the whole child — and the whole family
This one runs alongside everything else, not after it, because a nervous system that doesn't feel safe can't settle no matter how good the medical plan is. That can include therapy with a clinician who understands PANS-related OCD and anxiety, protected and consistent sleep, gentle movement your child actually enjoys, and simple daily practices — slow breathing, humming, co-regulation — that help calm an overwhelmed nervous system. It also means supporting you, because a flare doesn't just happen to a child; it happens to a whole household. When a child needs psychiatric support during an acute flare, that's a tool we coordinate, not a failure. If sleep and behavior are where this shows up hardest in your home, pediatric sleep and behavior support is part of this same picture.
"That's a lot." Here's how it actually works in real life.
If you read that list and felt your stomach drop — I get it. On paper, a full PANS framework can look like dozens of moving parts. In practice, it almost never is, for two reasons.
First, things consolidate. Many of the supports do more than one job at once, so a thoughtful plan usually comes down to a manageable handful of changes, not a kitchen counter full of bottles. Second, it's sequenced. We don't do everything on day one. We start with the foundation that matters most for your child, see how their body responds, and layer in the next piece only when it's needed. The detective work is mine to carry. Your job is to live your life and watch your kid come back.
And that's the other thing I want you to hear: this is a map, not a prescription. I can't tell you through a blog post what your child needs, in what order, or at what dose — and you should be skeptical of anyone who tries. Every plan is built one child at a time, from their own history, exam, and testing, and co-managed with your child's medical team.
When functional medicine isn't the whole answer
I'll always tell you the truth about what I can and can't do. Functional medicine is powerful for finding and fixing what's been missed — but some moments call for conventional or emergency care first. A child in an acute psychiatric crisis, expressing thoughts of harming themselves, or refusing to eat or drink, needs urgent medical and psychiatric care right away. My role is to work alongside that care — to be the person who stays in the room, connects the dots, and keeps advocating for your child through all of it.
If your child is in crisis, call 911 or your local emergency number, or reach the 988 Suicide & Crisis Lifeline.
How this works at Happy Kid Functional Medicine
Most of the families who find me have already done a lot — labs, referrals, therapies, specialists — and they arrive carrying a folder of "normal" results and a stubborn feeling that something is being missed. My job is to find what that is. Through the Missing Piece Method, I map your child's full timeline, order the testing that explains what's happening inside their body, and build a plan that fits the life your family is actually living. I see families in person in Omaha, and I offer telehealth in Arizona, Colorado, Iowa, Nebraska, Tennessee, and Virginia — so wherever you are in those states, you don't have to keep searching for someone who gets it.
PANS and PANDAS rarely travel alone, either — the same immune and gut patterns often sit underneath attention and focus struggles and other chronic symptoms, which is why whole-child care matters so much here.
The most common thing I hear from parents a few months in is some version of I feel like I have my kid back. That's where we start — and it keeps getting better from there.
Frequently asked questions
How long does PANS or PANDAS treatment take? It varies widely — from weeks to many months — depending on how early it's caught, how severe it is, and what's driving it underneath. The goal is steady, durable progress, not a quick fix that doesn't hold.
Can PANS or PANDAS be treated naturally? Root-cause and natural supports — anti-inflammatory nutrition, gut repair, nervous-system regulation — are a major part of the framework and can do a lot of good. But "naturally" doesn't mean "instead of" conventional care. The strongest results come from using both together, especially in the early or severe stages.
Do you treat the strep, or does my pediatrician? Treating active infection is typically coordinated with your child's pediatrician. I focus on the root-cause and whole-child layers and work alongside your existing medical team rather than replacing them.
Will treating my child's gut help their PANS symptoms? For many children, yes — because so much of the immune system lives in the gut, calming gut inflammation can help calm the immune overreaction driving symptoms. Whether it's a priority for your child depends on what their testing shows.
Where are you located, and do you offer telehealth? I'm physically located in Omaha, Nebraska, where I see families in person. I also offer telehealth and am licensed to see patients virtually in six states: Arizona, Colorado, Iowa, Nebraska, Tennessee, and Virginia. If you're in any of those states, we can do this entirely online.
