PANS and PANDAS: What Parents Should Know A Therapist's Perspective
How a Family Therapist Sees These Frequently Missed Conditions and What It Means for Your Child's Emotional and Behavioral Health

Treatment for Neurodivergent Children and Families

If your child seemed fine and then suddenly was not, with OCD behaviors, intense emotional dysregulation, unexplained tics, or dramatic personality changes appearing seemingly out of nowhere, PANS and PANDAS belong on your radar. PANS stands for Pediatric Acute-onset Neuropsychiatric Syndrome, and PANDAS, which is a subset of PANS, stands for Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal Infections. Both conditions involve the immune system triggering a neurological response that produces sudden and often severe psychiatric and behavioral symptoms in children. These conditions are frequently missed, frequently misdiagnosed as purely behavioral or psychiatric, and frequently undertreated because the medical component is not identified. For a parent watching their child change rapidly and inexplicably, understanding that there may be a physiological driver behind what they are seeing changes everything about where they look for help.
If your child came to mind while reading that, you are in exactly the right place. Kimberley Clayton Blaine, MA, LMFT works with families like yours through teletherapy, parent coaching, and online courses. Her books on understanding emotionally complex children are available at TheMisunderstoodChild.com. When you are ready, begin support here.
› PANS and PANDAS are medical conditions with psychiatric and behavioral symptoms.
They are not primarily behavioral disorders or parenting failures. They occur when an infection or immune response triggers inflammation that affects the brain, producing sudden changes in mood, behavior, cognition, and movement that can look like OCD, anxiety, ADHD, or emotional dysregulation.
› The hallmark warning sign is sudden dramatic onset or worsening of symptoms.
A child who develops OCD behaviors, severe separation anxiety, emotional explosiveness, tics, or cognitive decline seemingly overnight, particularly following an illness, should be evaluated for PANS or PANDAS rather than having the symptoms attributed only to a pre-existing condition or behavioral choice.
› Children with ADHD are particularly vulnerable because they often have lower immune function.
This means they get sick more frequently, which increases their exposure to the
infectious triggers associated with PANS. It also means that when OCD-like behaviors emerge in a child who already has an ADHD diagnosis, the PANS component is easily missed because everything gets attributed to the existing diagnosis.
› A standard pediatric checkup will not catch this.
Proper evaluation requires bloodwork through a pediatric autoimmune specialist or immunologist who can test for the specific markers associated with PANS and PANDAS. Infections including strep, Lyme disease, influenza, and COVID have all been identified as triggers, and the appropriate specialist will know which markers to look for.
› A course of antibiotics often produces meaningful symptom improvement, which is itself diagnostic.
When behavioral and psychiatric symptoms significantly reduce in response to
antibiotic treatment, that response confirms the immune-driven nature of what was happening. Working from the inside out, addressing the medical piece thoroughly before assuming symptoms are purely psychiatric, is the foundational clinical principle here.
A DEEPER LOOK FROM A SPECIALIST

Why PANS and PANDAS Get Missed and What That Costs Families
If your child has been sickly, has had repeated strep infections in the preschool years, or seems to get sick far more often than other children, that history matters clinically and it needs to be part of any conversation about sudden behavioral or emotional changes. Children with ADHD often have lower immune function and get sick frequently, which makes this picture even more complex. When OCD-like behaviors begin to emerge in a child who already has an ADHD diagnosis, families and clinicians alike may attribute everything to the existing diagnosis and miss what is actually a separate medical process happening underneath. PANS and PANDAS are frequently overlooked because the behavioral changes they produce look like psychiatric conditions rather than immune responses. The delay in identifying the medical component means children sometimes spend months or even years in behavioral or psychiatric treatment for something that has a physiological driver requiring medical intervention alongside everything else.
What to Do When You Suspect PANS or PANDAS and Keep Getting Dismissed
The first step is to consult with a pediatric autoimmune specialist or immunologist who can order the appropriate bloodwork. There are specific markers in the blood that point toward these conditions, and a standard pediatric checkup will not catch them. Lyme disease, COVID, influenza, and even a common cold or upper respiratory infection can trigger a PANS response because the body's immune system turns on itself and the brain becomes affected in the process. I have seen it in my practice repeatedly: a child develops mild congestion and within days the family is managing behavioral changes that are completely out of proportion to a typical illness. If your pediatrician tells you it is just anxiety or behavioral and your instinct tells you something is different, trust that instinct and ask specifically for a referral to a specialist who works with pediatric autoimmune conditions. A targeted course of antibiotics often produces meaningful improvement in symptoms, which is itself important diagnostic information. Always working from the inside out, addressing the medical piece first and thoroughly, is how we make sure nothing is missed.
What the Road to Support Looks Like After a Diagnosis
Once PANS or PANDAS is identified, the treatment team needs to span both medical and therapeutic disciplines. A pediatric autoimmune physician manages the medical side. A therapist familiar with the condition supports the child and family through what can be a prolonged and unpredictable recovery process. The school also needs to be brought in as a partner, because this condition can affect a child's functioning for weeks or even months while medical treatment takes effect. Collaborating with the school to establish appropriate accommodations and a flexible academic plan during the treatment period is essential, not optional. Children navigating a PANS or PANDAS episode are genuinely unwell in ways that are not always visible, and the school environment needs to reflect that reality. Because research in this area is still developing, parents often find themselves educating the adults around their
child about what this condition is and what it requires. That advocacy role is real and demanding, and families should not have to carry it alone.
What are the warning signs of PANS or PANDAS I should watch for in my child?
The most significant warning sign is sudden dramatic onset of symptoms that were not previously present or a rapid severe worsening of symptoms that already existed, particularly following an illness. Sudden OCD behaviors, intense separation anxiety, emotional explosiveness, unexplained tics, handwriting deterioration, food restriction, urinary frequency, and a general sense that your child has changed personality practically overnight are all symptoms that warrant further evaluation. The key word is sudden. PANS and PANDAS do not develop gradually. They tend to arrive quickly and
noticeably, often within twenty-four to seventy-two hours of an infection.
My child has ADHD. Could they also have PANS or PANDAS?
Yes, and this combination is more common than most families realize. Children with ADHD frequently have immune system vulnerabilities that make them more susceptible to the infections that trigger PANS. When a child who already has an ADHD diagnosis suddenly develops OCD behaviors, dramatic emotional changes, or other symptoms that feel qualitatively different from their usual presentation, PANS or PANDAS should be considered as a contributing factor rather than assuming everything is explained by the existing diagnosis. A medical evaluation alongside the existing therapeutic and psychiatric support is the appropriate next step.
What kind of doctor should I take my child to if I suspect PANS or PANDAS?
Start by asking your pediatrician for a referral to a pediatric immunologist, a pediatric rheumatologist, or a clinician who specifically identifies as having experience with PANS and PANDAS. Not all pediatricians are familiar with these conditions, and not all specialists are either. The PANDAS Physicians Network maintains a directory of providers who work with these conditions and can be a useful starting point for families who are having difficulty finding knowledgeable medical support. Bringing documentation of your child's symptom timeline, including the relationship between illnesses and behavioral changes, to any appointment will strengthen the evaluation process significantly.
How long does it take for a child with PANS or PANDAS to recover?
Recovery timelines vary considerably depending on how quickly the condition is identified, how effectively the underlying infection or immune trigger is treated, and the individual child's biology. Some children respond dramatically to a course of antibiotics within weeks. Others have a more prolonged course that requires ongoing medical management over months. Flares triggered by subsequent illnesses are common, which means families need to stay vigilant about infections and have a response plan in place. Therapeutic support for the child and the family during the recovery period is an important part of the picture, because the behavioral and emotional symptoms that accompany a PANS episode are genuinely distressing for everyone in the household.
