If you’ve ever watched your child transform suddenly — tics appearing out of nowhere, anxiety spiking to an unrecognizable level, handwriting deteriorating, personality shifting — you may have been told it’s behavioral, or developmental, or “just a phase.”

But what if it started right after strep? Or after a flu? What if it came on in days, not weeks?

If that sounds familiar, PANS and PANDAS may be worth understanding.

What Are PANS and PANDAS?

PANDAS stands for Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal Infections. PANS (Pediatric Acute-onset Neuropsychiatric Syndrome) is the broader umbrella — it includes any sudden-onset neuropsychiatric episode triggered by an infection or immune dysregulation, not just strep.

In both conditions, the body’s immune response to infection misfires and begins attacking brain tissue — specifically the basal ganglia, a region involved in movement, behavior, and emotional regulation. The result can look like a psychiatric emergency, but the root cause is immunological.

What Does It Look Like in Children?

PANS/PANDAS is diagnosed clinically, and every child presents differently. But there are hallmark features that providers trained in this area recognize:

• Sudden, dramatic onset of OCD-like behaviors or severe anxiety
• Tics (motor or vocal) that appear abruptly
• Emotional lability — extreme mood swings, rage episodes, or sudden regression
• Separation anxiety that seems to come from nowhere
• Urinary frequency or sudden bedwetting in a child who was previously dry
• Handwriting or fine motor deterioration
• Cognitive fog, difficulty concentrating, or a sudden decline in school performance

The sudden onset is the key distinguishing factor. PANS/PANDAS does not creep in gradually. It arrives — often following an infection by days or weeks.

Why So Many Families Are Dismissed

This is one of the most heartbreaking parts of what we see at GAIP. Families often spend years seeking answers — seeing neurologists, psychiatrists, and pediatricians — and are told that what they’re describing isn’t possible, or that their child simply has anxiety or OCD.

The medical community’s awareness of PANS/PANDAS has improved significantly, but many providers were not trained to recognize it. Behavioral symptoms are often funneled into behavioral diagnoses. And without a provider who knows what to look for, the immune connection is missed.

If you have been dismissed, I want you to know: you are not imagining this. And there are providers who take this seriously.

What Evaluation Looks Like at GAIP

At Greater Atlanta Integrative Pediatrics, we approach PANS/PANDAS with both urgency and thoroughness. A typical evaluation includes:

• A detailed symptom and onset timeline
• Strep cultures and titers (ASO, Anti-DNase B)
• Comprehensive immune panel
• Mycoplasma, Lyme, and other infectious triggers when clinically indicated
• Inflammatory markers

We are not looking for a single positive test to make this diagnosis — we are looking at the whole picture. Onset history matters enormously.

Treatment Is Possible — and Kids Can Recover

This is what I most want parents to hear: children with PANS/PANDAS can get significantly better. Treatment typically involves addressing the underlying infectious trigger, supporting immune regulation, and — when appropriate — anti-inflammatory support.

Recovery is often nonlinear. There can be flares. But with the right support, many children return to themselves.
