When Sudden Changes Leave You Searching for Answers
Sometimes a child’s behavior or personality can seem to change almost overnight. A once carefree child may suddenly become anxious, withdrawn, or display obsessive, fearful, or unusual behaviors. For parents, this sudden shift can feel confusing, overwhelming, and deeply unsettling.
For some families, these changes may be connected to PANS (Pediatric Acute-onset Neuropsychiatric Syndrome) or PANDAS (Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal Infections)—conditions that can cause an abrupt change in a child’s emotions, behavior, and overall functioning.
At New Heart Therapy, we offer compassionate, specialized support for children and families navigating the challenges of PANS and PANDAS. Our goal is to help your child feel safe and understood, while supporting your family in restoring stability, connection, and hope.
PANDAS occurs when a streptococcal infection triggers an autoimmune response that affects areas of the brain involved in behavior, emotions, and movement.
PANS describes a similar sudden onset of symptoms that may be triggered by other infections, immune responses, or environmental factors.
Symptoms can emerge rapidly—sometimes within hours or days—and may fluctuate over time. In many cases, early signs are missed or mistaken for typical developmental changes, stress, or illness.
While each child’s experience is unique, there are common patterns families often notice.
Children with PANS or PANDAS may experience a range of symptoms, including:
Obsessive-compulsive behaviors (OCD)
Sudden anxiety, fears, or separation anxiety
Mood swings, irritability, or aggression
Tics or repetitive movements
Sleep disturbances
Changes in appetite or food restriction
Regression in age-appropriate skills
Difficulty concentrating or sudden academic decline
These symptoms can be intense and distressing for both children and their families. Therapy can help make sense of what’s happening and provide tools for navigating daily life with greater confidence and support.
Medical treatment addresses the physical and biological aspects of PANS and PANDAS, while therapy supports the emotional, behavioral, and relational impact on the child and family.
At New Heart Therapy, we use a family-centered, trauma-informed approach and have experience supporting children with sudden-onset neuropsychiatric symptoms. Therapy may help families:
Manage anxiety, OCD, and emotional distress
Support emotional regulation and resilience in children
Strengthen family communication and connection
Provide parents with guidance for responding to challenging behaviors
Collaborate with medical providers and schools
Our focus is not just on reducing symptoms, but on helping families feel supported, informed, and empowered throughout the process.
When a child is struggling, the entire family feels the impact. Parents may feel exhausted or uncertain, while siblings may feel worried, confused, or overlooked.
In therapy, we work together to:
Restore a sense of safety and stability at home
Understand and respond to behavioral changes with confidence
Reduce family stress and support caregivers
Strengthen resilience, connection, and hope
You don’t have to navigate this alone. Healing is possible, and support is available.
PANS and PANDAS often require coordinated care. We collaborate with:
Pediatricians and medical specialists
Psychiatrists for medication support, when appropriate
School staff to assist with academic and emotional accommodations
This team-based approach helps ensure your child receives consistent, compassionate care across all areas of life.
