Episode Details

When a child suddenly develops anxiety, rage, tics, restrictive eating, or emotional volatility, the system rushes to label and medicate it. But what if those behaviors aren't psychological at all? What if they're inflammatory? What if the brain isn't "misfiring," but reacting loudly to an immune system that's overwhelmed, dysregulated, and unable to turn itself off?

In my work, I've watched this pattern repeat over and over. Kids change "overnight," parents think "I've lost my child," and the healthcare system rarely asks the most important question: what happened before the behavior changed?

In today's world, children are exposed to environmental toxins, infections, immune stress, chronic inflammation, and genetic vulnerabilities. These lead to the very common sudden behavioral and emotional changes we're seeing in so many young people.

And childhood immune dysregulation doesn't stay in childhood. Untreated neuroinflammation can follow kids into adolescence, adulthood, and eventually shape entire family trees.

How do we reduce the physical stress driving these changes in so many children and families? What's actually happening beneath the surface of conditions like PANS/PANDAS, eczema, autism, anxiety, and sudden behavioral regression?

To unpack this, I'm joined by Dr. Paula Kruppstadt, a board-certified pediatrician and functional medicine physician who works with some of the most complex pediatric cases.

She explains what's driving these sudden changes, why standard approaches often miss it, and what actually helps kids stabilize and recover.

Things You'll Learn In This Episode

When behavior is actually a physical issue Sudden mood swings, anxiety, rage, tics, or regression are often treated as "behavior problems." What if it's a sign that inflammation or infection is affecting how your child feels and acts?

Why "it happened overnight" actually matters If your child seemed fine and then suddenly wasn't, that change isn't random. What can abrupt shifts tell you about underlying health issues that often get missed?

Food programs immunity How can common foods like gluten, dairy, dyes, and additives quietly contribute to eczema, anxiety, and emotional ups and downs, even when kids seem otherwise healthy?

A more precise way to vaccinate Most parents are told to stick to the routine vaccine schedule, but that can push a child's system too hard, too fast. How do we give kids vaccines in a way that protects immunity without unnecessarily adding inflammatory load?
