PANS & PANDAS in children: a functional medicine guide.
Your child went to bed one person and woke up someone you almost didn't recognize. When symptoms like these show up almost overnight — often after a strep throat or another infection — there's a name for what you may be seeing: PANS or PANDAS.
I'm Dr. Amy Patton. I help families find what's been missed and build a root-cause plan for their child — one that works alongside your pediatrician and specialists, not instead of them.
- QUICK ANSWER
What are PANS and PANDAS?
PANS and PANDAS are conditions where a child develops a sudden, dramatic change in behavior — most often obsessive-compulsive behavior or a sharp drop in eating — believed to be driven by the immune system overreacting to an infection or other trigger and inflaming the brain. PANDAS is the form specifically tied to strep. PANS is the broader term that includes other triggers, like mycoplasma, viruses, and other infections. Both are diagnosed by a clinician based on the pattern and timing of symptoms — there is no single test that confirms them.
RECOGNITION
Does this sound like your child?
One month your child is fine. The next, they're washing their hands raw, refusing foods they used to love, going from zero to screaming in seconds over things that never used to matter. Maybe their handwriting fell apart. Maybe they stopped sleeping, started wetting the bed again, or began having thoughts and fears that frighten you both. Maybe the school is calling and you don't recognize the child they're describing.
You've tried the strategies. You've read the books. You've adjusted the parenting, the schedule, the diet. And your child is still struggling in ways that don't make sense — ways nobody seems able to fully explain. If you've been told to give it more time, give the therapy longer, or accept this as your new normal, and your gut keeps telling you something is being missed — that instinct is worth listening to. Sudden, dramatic change in a child is information. It is the body trying to tell us something.

WHAT IT IS
What is PANDAS?
What is PANS?
PANDAS stands for Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal infections. In plain language: a child develops sudden OCD, tics, or both shortly after a strep infection, because the immune system's response to strep also affects the brain.
PANS stands for Pediatric Acute-onset Neuropsychiatric Syndrome. It's the umbrella term. PANS includes the same overnight onset of OCD or severely restricted eating, but the trigger doesn't have to be strep — it can be mycoplasma (walking pneumonia), the flu, a sinus infection, other viruses, and in some children, non-infectious triggers. PANDAS sits underneath PANS as the strep-specific version.
What's actually happening in the body?
The leading explanation is this: while the immune system is busy fighting an infection, it
mistakes part of the brain for the invader and creates inflammation in a region called the basal
ganglia — the part of the brain that helps regulate movement, emotion, and impulse control.
That's why a throat infection can show up weeks later as OCD, tics, or rage. Researchers call
this a post-infectious, autoimmune, or neuroinflammatory process, and in well-studied groups of
PANS patients, signs of this kind of immune activation or brain inflammation show up in the
large majority of cases.
The science is still evolving, and not every expert agrees on every detail — but the core idea that an immune trigger can drive sudden neuropsychiatric symptoms in children is well documented and taken seriously by major pediatric and research institutions.
SYMPTOMS
What are the symptoms of PANS and PANDAS in children?
The defining feature is how fast it appears. PANS and PANDAS don't creep in over months. Parents can often name the week — sometimes the day — everything changed.
The two "anchor" symptoms
Almost every case starts with at least one of these, coming on suddenly and dramatically.
Obsessive-compulsive behavior
Intrusive fears, rituals, checking, contamination worries, “just right” compulsions.
The symptoms that come with it
Alongside an anchor symptom, children usually show a sudden change in at least two of these areas:
-
Intense anxiety, including separation anxiety that seems much younger than their age
-
Mood swings, irritability, aggression, or rage episodes
-
Behavioral or developmental regression (acting much younger than before)
-
A sudden drop in school performance, focus, or memory
-
Sensory sensitivities or motor changes, including tics and deterioration in handwriting
-
Sleep disruption, bedwetting, or new urinary urgency and frequency
Severely restricted eating
Sudden food refusal or fear of food — often tied to fears of choking, vomiting, or contamination.
Common triggers besides strep
Not every case starts with strep.
-
Strep (the classic PANDAS trigger)
-
Mycoplasma pneumoniae (“walking pneumonia”)
-
Influenza and other common viruses
-
Sinus and upper-respiratory infections
-
Environmental triggers, including mold and mycotoxin exposure
-
Tick-borne infections such as Lyme and its co-infections
-
Other infections or significant immune or inflammatory stressors
DIAGNOSIS
How are PANS and PANDAS diagnosed?
There is no single blood test that proves a child has PANS or PANDAS. It is a clinical diagnosis — a trained provider puts together the timeline, the symptom pattern, an exam, and lab work, and rules out other explanations. A normal strep test or normal titers do not rule it out, and positive labs alone do not confirm it. The story matters as much as the numbers.
01
Sudden, dramatic onset
Of OCD or severely restricted eating.
02
Plus symptoms in 2+ areas
Anxiety, mood/rage, regression, school decline, sensory/motor, sleep or urinary changes.
03
Common triggers besides strep
Other known conditions are considered and ruled out.
The lab work often considered
-
Evidence of strep, current or recent (throat culture, ASO and anti-DNase B titers)
-
Other infectious triggers when the history points there (e.g. mycoplasma)
-
General markers of inflammation and a basic blood count
-
Other testing to rule out conditions that can look similar
What a functional workup adds
Conventional testing answers “is there an immune trigger, and what is it?” A functional medicine workup goes a step further and asks “what in this child's body is keeping the fire burning?” That can mean a closer look at gut health, nutrient status, food sensitivities, mast cell and histamine patterns, and — when it's truly indicated — genomics. The goal isn't more tests. The goal is to find the specific, fixable things amplifying your child's symptoms.
This list helps you recognize a pattern. It does not diagnose your child. Many of these symptoms overlap with other conditions, which is exactly why a careful workup matters.
TREATMENT FRAMEWORK
How is PANS and PANDAS treated?
There's a well-established medical framework for PANS and PANDAS, and the best results usually come from using both halves of it: the conventional care that calms a crisis, and the root-cause work that keeps it from coming back.
01
Find and treat the trigger
Identify and address the infection or immune stressor that set things off, usually with your pediatrician.
04
Address what's underneath
Gut health, nutrient gaps, food sensitivities, and other drivers — guided by your child's testing.
02
Calm the inflammation
Bring down the brain inflammation so your child gets real, felt relief.
05
Support the whole child
Nervous system, sleep, therapy, and the people in the house — all at once.
03
Steady the immune system
Help the immune system stop overreacting so flares get less frequent and less severe.
06
Co-manage with your team
I work alongside your pediatrician and specialists, never instead of them.
Important. This is the shape of a plan, not a prescription. No two children get the same plan — everything is individualized to your child and co-managed with your medical team.

SAFETY
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.
Severe cases that may need treatments like IVIG belong with a specialist immune team. My role is to work alongside those providers — to be the person who stays in the room, connects the dots, and keeps advocating for your child through all of it.
Happy Kid Functional Medicine is not an emergency or urgent-care service. If your child is in crisis, call 911 or your local emergency number, or reach the 988 Suicide & Crisis Lifeline.
HOW I HELP
How I help PANS and PANDAS families.
Most of the families who find me have already done a lot — labs, referrals, therapies, specialists — and they're carrying a folder of "normal" results and a persistent 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 actually 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 by telehealth across Arizona, Colorado, Iowa, Nebraska, Tennessee, and Virginia, so wherever you are, you don't have to keep searching for someone who gets it.
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.
