What Causes PANS/PANDAS: Early Signs and Triggers

Watching your child suddenly spiral with OCD, anxiety, mood swings, or school refusal can feel terrifying. Understanding what causes PANS/PANDAS is the first step to supporting a dysregulated child. In this episode, Dr. Roseann breaks down the triggers, early warning signs, and practical strategies to calm the nervous system, reduce flares, and support emotional regulation.

Why does my child develop PANS/PANDAS suddenly?

PANS (Pediatric Acute-onset Neuropsychiatric Syndrome) and PANDAS (Pediatric Autoimmune Neuropsychiatric Disorder Associated with Strep) often appear overnight due to infections, toxins, or autoimmune responses.

Key contributors:

• PANDAS: triggered by strep
• PANS: triggered by flu, Epstein-Barr, COVID, or tick-borne infections
• Neuroinflammation affecting mood, cognition, and behavior

Parent story: An 8-year-old appeared fine until a mild flu triggered severe OCD and anxiety rituals within days.

How do environmental factors trigger flares?

Beyond infections, toxins, mold, allergens, and chemicals can worsen symptoms:

• Immune dysregulation: genetics, poor diet, stress, prior illness
• Environmental triggers: mold, pesticides, cleaning chemicals, synthetic fabrics

Can nervous system dysregulation worsen symptoms?

Chronic stress or trauma prevents the brain from calming, making flares more likely.

Supports for regulation:

• Nutrients: magnesium, vitamin C, vitamin D
• Calming strategies: co-regulation, rhythmic movement, breathwork
• Consistency: predictable routines reduce nervous system overactivation

Parent story: Daily calming routines decreased flare severity even during minor infections.

How diet and nutrition impact flares

Food choices directly affect inflammation and symptom intensity.

Recommendations:

• Include bone broth, smoothies, anti-inflammatory foods, and targeted supplements
• Avoid sugar, dairy, wheat, and highly processed foods
• Track meals vs. symptoms to see patterns

FAQs

Q1: What triggers PANS/PANDAS flares?

A: Infections, immune response, toxins, environmental triggers, and stress.

Q2: Can anxiety or OCD be the first sign?

A: Yes. Emotional symptoms often appear before tics or physical signs.

Q3: How can I reduce flare intensity at home?

A: Calm the nervous system first with co-regulation, predictable routines, and sensory supports.

Q4: Should I track symptoms daily?

A: Yes. Linking behavior to illness, stress, or environment helps guide interventions.

Q5: Is PANS/PANDAS preventable?

A: Early recognition, immune support, and nervous system regulation reduce severity and duration of flares.
