About this Episode

When Behavior Changes Aren’t “Just Behavioral”

In this episode of Look for the Helpers, a podcast by Engage Therapy, we sit down with Tanya Altmann, MD, a pediatrician practicing in Calabasas at Calabasas Pediatrics, to discuss what can happen when a child’s behavior shifts suddenly and dramatically.

Dr. Altmann explains PANS and PANDAS — pediatric autoimmune conditions in which an immune response to infection may impact the brain, sometimes leading to abrupt onset of anxiety, OCD symptoms, tics, mood changes, or regression.

For families, these shifts can feel frightening and disorienting. Many parents describe it as, “This isn’t my child anymore.”

At Engage Therapy, we regularly work with youth and families across Agoura Hills, Westlake Village, Thousand Oaks, Calabasas, Malibu, Simi Valley, Moorpark, and Camarillo who are navigating anxiety, depression, and complex behavioral concerns.

In addition to outpatient therapy, we offer Intensive Outpatient (IOP) programs for youth and young adults ages 10–25 who are experiencing depression or anxiety and need structured support while remaining connected to school and home.

While this episode is educational in nature, it is not a substitute for medical or mental health care. If you are concerned about sudden changes in your child, we encourage you to consult your pediatrician or a licensed mental health professional.

Frequently Asked Questions

What are PANS and PANDAS?

PANS (Pediatric Acute-onset Neuropsychiatric Syndrome) and PANDAS (its strep-associated form) describe a sudden onset of OCD-like symptoms, anxiety, tics, or behavior changes in children, often following an infection.

How is this different from ordinary behavior changes?

The hallmark is abrupt, dramatic onset. Symptoms appear almost overnight rather than building gradually, which is a signal to involve both pediatric and mental-health care.

What should a parent do if a child changes overnight?

Note when symptoms started, ask your pediatrician about a medical workup including infection, and involve a mental-health clinician. Early, coordinated care matters most.

Who treats PANS and PANDAS?

It usually takes a team: a pediatrician for the medical side and a therapist or psychiatrist for the mental-health side. Engage Therapy works alongside families across the Conejo Valley.
