Something feels off even when tests come back normal. Discover the hidden signs of PANS/PANDAS every parent misses as Dr. Nancy O’Hara unpacks sudden symptoms often mistaken for ADHD, anxiety, or autism. Dr. Roseann Capanna-Hodge, expert in Regulation First Parenting™, guides parents through emotional dysregulation and what to do next.
Parents often know something is wrong—even when tests come back “normal.” In this powerful conversation with Dr. Nancy O’Hara, we explore the hidden signs of PANS/PANDAS every parent misses, and why so many children are misdiagnosed with ADHD, anxiety, or even autism.
The truth? Sudden behavioral shifts, OCD, and physical symptoms may signal immune-driven brain inflammation—not “just behavior.” In this episode, you’ll learn what PANS/PANDAS really is, how it affects the brain, and the overlooked signs parents and providers often miss.
Why did my child suddenly change behavior overnight?
When a child shifts abruptly—from calm to anxious, obsessive, or emotionally reactive—it can feel confusing and scary for parents.
Dr. O’Hara explains that this sudden onset is a key marker of PANS/PANDAS, often triggered by infection or immune dysregulation.
What parents should know:
Sudden onset matters—changes can happen within days to weeks
OCD, anxiety, or eating changes may appear quickly
It’s not bad parenting—it’s a dysregulated immune response
Triggers may include strep, viruses, mold, or environmental stressors
Real-Life Example: A child who was once easygoing suddenly develops intense fears, refuses foods, or becomes highly anxious after an illness.
As I always remind parents, behavior is communication—and sudden shifts deserve deeper investigation.
Is OCD in kids always obvious—or can it be hidden?
One of the most missed signs of PANS/PANDAS is hidden OCD, especially intrusive thoughts that don’t look like typical compulsions.
Dr. O’Hara emphasizes that many children suffer silently.
Hidden OCD signs include:
Intrusive, scary thoughts they can’t explain
Withdrawal, shutdown, or emotional overwhelm
Avoidance of situations without clear reason
Shame or embarrassment about thoughts
A child seems “anxious about everything,” but underneath is a looping fear they can’t verbalize.
This is where misdiagnosis often happens. It may look like generalized anxiety or even ADHD—but it’s actually neurological inflammation affecting the brain’s fear circuits.
Let’s be clear: your child is not choosing this. Their brain is overwhelmed.
Why are medical tests normal if my child is struggling so much?
This is one of the most frustrating experiences for parents—being told everything is “fine” when it clearly isn’t.
Dr. O’Hara explains that PANS/PANDAS is primarily a clinical diagnosis, not a lab-based one.
Key insights:
Bloodwork can look completely normal
Some children cannot mount detectable immune responses
Inflammation may still be present in the brain
Diagnosis relies heavily on pattern recognition + history
Real-Life Example: A child with severe behavioral changes has “normal labs,” leading families to feel dismissed—despite clear real-world impairment.
This is where validation matters. You’re not imagining it.
You don’t have to figure this out alone.

What physical symptoms are easy to miss in PANS/PANDAS?
Parents often focus on behavior and miss the body-based clues.
Dr. O’Hara highlights that somatic symptoms are frequently overlooked—but incredibly important.
Common missed signs:
Urinary frequency or urgency
Bedwetting after being dry
Sleep disturbances or restless sleep
Handwriting changes or regression
Sensory overload or motor changes
Real-Life Example: A child begins waking frequently at night and having bathroom accidents alongside new anxiety.
These symptoms reflect nervous system dysregulation—not defiance or regression without cause.
🗣️ “Parents know something’s wrong, but all those tests and professionals say it’s normal.” — Dr. Roseann
Why is inflammation in the brain so often misunderstood?
Dr. O’Hara explains that infections like strep, Lyme, viruses, and even mold exposure can trigger immune responses that affect the brain—especially the basal ganglia, which controls behavior, emotion, and movement.
Key takeaways:
Genetics load the gun, environment pulls the trigger
Immune system may mistakenly attack brain tissue
Symptoms can overlap with autism, ADHD, or anxiety
COVID has increased post-infectious cases
This is why children can suddenly look “different”—because their brain is under inflammatory stress.
Takeaway & What’s Next
PANS/PANDAS is often misunderstood, misdiagnosed, and missed entirely—but awareness changes everything. When parents learn to recognize the hidden signs, they can finally stop blaming themselves and start supporting the brain and body together.
