About five years ago, a parent came into the pharmacy to pick up an antipsychotic for her child. When I asked how things were going, she said something I've never forgotten: "He just changed overnight." One day she had her kid. The next day she didn't. And the answer from the medical system was a psychiatric drug. My first thought wasn't about the prescription in my hand. It was, what did this doctor miss? That question is exactly what I dig into in this week's episode of The Trusted Pharmacist with Dr. Paula Kruppstadt.
At the pharmacy, we're seeing rising rates of anxiety, ADHD, tics, and sudden behavioral changes in kids. And too often, the conversation stops at the label. Your child gets a diagnosis, a prescription, and a follow-up appointment. Almost nobody asks why a healthy kid fell apart in the first place.
The Problem Isn't Behavior. It's Inflammation.
Dr. Kruppstadt is a board certified pediatrician and functional medicine expert who works with complex kids every day, including patients we share. When a parent tells her "my child changed overnight," her answer is direct: that's brain inflammation until proven otherwise.
The way she puts it stuck with me. When your brain is hot, red, swollen, and painful, a child can't unzip their skull and show you. So the inflammation shows up as emotional dysregulation instead. Rage. Tics. Obsessive behaviors that appeared out of nowhere.
About 25 percent of kids carry a genetic vulnerability where the immune system can't tag infections correctly. Instead of clearing the bug and moving on, the body floods with inflammation that attacks the brain itself. Strep, influenza, COVID, Lyme, and Bartonella can all set it off. During COVID, Dr. Kruppstadt watched kids change overnight in exactly this pattern.
What You Actually Need to Know
What PANS and PANDAS Actually Are
PANS stands for pediatric acute-onset neuropsychiatric syndrome. That's the umbrella term. PANDAS sits underneath it and involves one specific trigger: Group A beta-hemolytic strep, the same bacteria behind strep throat.
You already know part of this story. Untreated strep can cause rheumatic heart disease, an autoimmune attack on the heart. PANDAS is the same mechanism with a different target. The immune system attacks the brain, specifically the basal ganglia, which controls movement, neurotransmitter production, and appetite.
What makes it easy to miss is that there may be no sore throat and no fever at all. Strep can hide in the skin, the gut, or the sinuses. Watch for overnight obsessive-compulsive behaviors, severe restrictive eating, profound separation anxiety, new bedwetting, tics, rage with dilated pupils, or handwriting that suddenly falls apart on the page. The website aspire.care has the full diagnostic checklist, and Dr. Kruppstadt walks parents through it in her own office.
The Workup Doesn't Require Exotic Testing
This surprised me. Dr. Kruppstadt runs most of her workup through LabCorp on a family's regular insurance. A throat culture, even when the tonsils look fine. Two antibody tests called anti-streptolysin O and DNase B, which show strep activity anywhere in the body. A urinalysis to rule out kidney involvement.
Then a careful physical exam. Bartonella, which kids can pick up from cats, sometimes leaves deep purple horizontal lines across the back and shoulders. There's a fancier option called the autoimmune brain panel, formerly the Cunningham panel, but she can usually reach an answer without it. A good history does most of the work.
Gluten, Dairy, and Your Child's Brain Chemistry
This is the part where most families push back, and I get it. Your brain has cerebral folate receptors that depend on vitamin B9 to help produce dopamine. Gluten and the proteins in cow's milk form short-chain opioids that bind to those receptors and block them.
Dopamine runs focus, short-term memory, sleep stability, and mood. Block the receptors, and a child struggles with all of it. Those opioid compounds are also genuinely addictive, which explains why kids fight so hard to keep their chicken nuggets and milk. Expect three to five rough days of withdrawal when you pull them. Grass-fed butter and ghee can stay.
The skin tells the same story. I see the eczema treadmill at the pharmacy constantly. A low-potency steroid cream works for two weeks, then the flare comes back, then it's medium potency, then high potency. Now you've got steroid absorbing through the skin and suppressing the HPA axis. Dr. Kruppstadt treats eczema from the inside out instead: pull the inflammatory foods, support glutathione, which is the body's master antioxidant concentrated in the gut and skin, and optimize vitamin D3 with K2. Vitamin D isn't really a vitamin. It's a secosteroid your body makes, and it belongs in the plan before the fourth tube of cream.
When the "Right" Supplement Backfires
I'm big on L-glutamine for healing the gut lining. So this pearl got my attention. Kids with a genetic marker called GAD1 can't handle L-glutamine, and it makes their anxiety dramatically worse. Same supplement, opposite result, all based on genetics.
Folate works the same way. Leucovorin, which is folinic acid, has been all over the news for autism. But if a child is still drinking cow's milk, the dairy proteins are binding those cerebral folate receptors, and the leucovorin can't do its job. Take out the dairy first. And methylfolate given to a kid who's still highly inflamed often produces anxiety, not improvement. Inflammation gets addressed first, then the nutrients get layered in. As a compounding pharmacist, I'll also tell you the commercially available leucovorin isn't clean. Pure compounded leucovorin from PCCA sourcing is a different product entirely.
Low Dose Naltrexone: Calming the Immune System Down
Naltrexone at high doses treats addiction. At low doses, it does something completely different. LDN briefly binds receptors called toll-like receptors, which quiets the chronic release of inflammatory signals, and the body responds by making its own endorphins.
Dr. Kruppstadt doses it in the morning, not at night, because it can cause vivid dreams and most of these kids already struggle to sleep. For babies, it can be applied topically to the pulse points on the feet. For children with autoimmunity or autism, she works up to 4.5 milligrams. This is a compounded prescription, and it's exactly the kind of work we do at Magnolia every day.
Start Here, Even Before the Next Appointment
You don't need a specialist referral to take the first step. Tonight, sit down with the checklist at aspire.care and note every symptom that matches what you're seeing. Bring that list to your pediatrician and ask for three specific things: a throat culture even if the throat looks fine, plus the anti-streptolysin O and DNase B blood tests. Those labs run through regular insurance and tell you whether strep is hiding somewhere in the body.
While you wait on answers, change what's on the plate. Gluten and cow's milk dairy go, for everyone in the house, because a child can't do this alone while everyone else eats pizza. The first three to five days are the hardest, then the withdrawal breaks. Ghee and grass-fed butter stay. And watch how you talk about it. Dr. Kruppstadt's rule: this is what helps us be our best, not something being taken away.
The Questions Don't Stop After the Appointment
If this episode hit home, you probably have more questions now than when you started. What labs should I ask for? Is this supplement right for my situation? Why does one kid react to something and another doesn't?
I hear versions of these questions at the pharmacy counter every single day.
And the hardest part isn't finding information. It's that nobody sits with you long enough to explain what applies to you, what doesn't, and what to actually do first.
The Magnolia Inner Circle exists to fix that.
It's where you bring your specific questions to pharmacists who answer them, where the topics from these episodes get broken down into steps you can act on, and where you stop being the only person responsible for figuring all of this out alone.
Membership also includes challenges, deeper trainings, community support, supplement discounts, and resources built to help you make confident decisions about your health.
