Every pediatrician and child psychologist knows the scenario: a child who was thriving suddenly refuses to eat, develops obsessive fears, cannot separate from parents, exhibits motor tics, or explodes in rage. Parents often describe it as a switch flipping, saying, "It's like I lost my child overnight." While these children are frequently diagnosed with anxiety, OCD, ADHD, or behavioral disorders, Dr. Roseann Capanna-Hodge, a children's mental health expert with over 30 years of experience, argues that such diagnoses may describe symptoms but not the underlying cause.
Drawing from more than 10,000 quantitative EEG brain maps and her own family's experience with PANS and Lyme disease, Dr. Roseann will present at NeuroImmune Day a call for clinicians to look beyond symptoms and consider how the nervous system, immune system, and brain interact when a child changes overnight. "When a child changes this dramatically, we have to ask a different question," she says. "Not simply, 'What diagnosis fits these symptoms?' but 'What changed biologically that caused this child to change so suddenly?'"
Conditions such as PANS (Pediatric Acute-onset Neuropsychiatric Syndrome), PANDAS, Lyme disease, and autoimmune encephalitis can trigger inflammation affecting the brain and nervous system, leading to dramatic behavioral shifts. Researchers estimate PANS may affect 1 in 200 children, yet many healthcare professionals lack training in recognizing it. Families often spend months or years searching for answers before biological questions are explored.
Dr. Roseann emphasizes that healing begins with the nervous system. "When the brain and body remain locked in chronic survival mode, healing becomes much more difficult," she explains. Her clinical framework, Regulation First®, views nervous system regulation as a biological prerequisite for healing. At NeuroImmune Day, she will present "PANS/PANDAS and the Whole-Body Matrix: Why Dysregulation Isn't Just a Brain Issue," exploring how chronic nervous system activation affects immune function, sleep, gut health, and executive functioning.
For parents whose child changes suddenly, Dr. Roseann advises not to wait. "Trust what you're seeing. Those changes deserve thoughtful medical evaluation and a conversation with clinicians who understand the connection between the brain, the immune system, and the nervous system." Her forthcoming book, The Dysregulated Kid: The Parenting Playbook for Helping Your Child Find Calm in a Chaotic World, published by Page Two Books on September 22, 2026, offers practical tools based on the Regulation First® framework, including the Love Pause® and CALMS Protocol®.
Dr. Roseann, featured in The New York Times, Forbes, and on NBC, CBS, and Fox, hosts the Dysregulated Kids podcast with over 2 million downloads. She believes that when clinicians and families understand the biological connections, new possibilities emerge for helping children who have remained stuck despite everyone's best efforts.
