When a Child Changes Overnight: PANS, PANDAS & the Overlap Between Pediatric and Mental Health Care

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.
