Watching your child’s behavior suddenly spiral can be terrifying and confusing. You might wonder if it’s just a phase, or if something more serious is happening. Understanding PANS/PANDAS and autoimmune encephalopathy is crucial because with the right information and diagnosis, you can access the right treatment—and start helping your child heal.

In this episode, I break down what parents need to know about diagnosing these conditions and how to recognize the signs of sudden behavioral changes.

How do I know if my child might have PANS or PANDAS?

Sudden onset or rapid worsening of behaviors can be a key sign. Parents often notice:

• Obsessive-compulsive behaviors that appear almost overnight
• Intense rage or emotional outbursts
• Regression in skills, like bedwetting or handwriting issues

One mom shared how her son, previously thriving, began having severe meltdowns and sudden OCD rituals after a strep infection. This is exactly the type of sudden shift that warrants evaluation.

Takeaways:

• Look for abrupt behavior changes, not gradual trends
• Keep a detailed timeline of symptoms
• Remember: behavior is communication from a dysregulated brain, not a character flaw

What tests are used to diagnose PANS/PANDAS?

There isn’t a single test for PANS/PANDAS. Diagnosis requires:

• Clinical criteria evaluation by a knowledgeable pediatrician or mental health professional
• Reviewing your child’s symptom history
• Bloodwork to rule out other conditions
• Optional brain mapping to understand neurological impacts

Parents often ask if lab tests alone can confirm PANS/PANDAS—unfortunately, they cannot. Diagnosis is based on patterns of behavior and medical history, not just test results.

Tip: Track infections, triggers, and symptom patterns carefully.

How is autoimmune encephalopathy different from PANS/PANDAS?

Both conditions involve the immune system attacking the brain, but:

• PANS/PANDAS usually has a sudden onset triggered by infections like strep
• Autoimmune encephalopathy can have slower, waxing-and-waning symptoms
• Both can present with behavioral, emotional, and learning changes

Parent Story

One parent described a child whose anxiety and aggression fluctuated for weeks before a pattern emerged—highlighting why professional evaluation is key.

Can early intervention improve outcomes?

Absolutely. Early recognition and tailored care make a huge difference:

• Brain-focused therapies can calm dysregulation
• Symptom-specific interventions (medication, therapy, nutrition) can support recovery
• Parental co-regulation—your calm helping your child feel safe—works wonders

🗣️ “Sometimes, these conditions are already existing but we just missed the signs. Look for sudden changes, and you can get your child the care they need.” — Dr. Roseann

What can parents do while awaiting diagnosis?

• Track behaviors and triggers in a journal
• Maintain predictable routines to reduce stress
• Focus on calming strategies for your child’s nervous system
• Advocate for your child with healthcare providers

It’s not about rushing a cure—it’s about creating a stable environment that supports healing.

FAQs

How quickly can my child improve after a PANS/PANDAS diagnosis?

Recovery varies for each child. Every brain and family is unique, so timelines are different.

Are strep infections always the trigger?

Can PANS/PANDAS appear in children who had no prior issues?

Yes. While some children have preexisting vulnerabilities, sudden behavioral changes can happen even in previously typical children.
