What Is PANDAS? (Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal Infections)
Imagine waking up one morning to find that your child has completely changed overnight. Suddenly, they’re experiencing severe obsessive-compulsive behaviors (OCD), motor tics, anxiety, or emotional outbursts—seemingly out of nowhere. If this happens after a strep throat infection, it could be PANDAS.
PANDAS is a rare but serious autoimmune condition in which a child’s immune system mistakenly attacks their brain, leading to sudden and severe mental health symptoms.
How Does PANDAS Happen?
PANDAS is triggered by a Group A Streptococcus infection (strep throat). Normally, the immune system produces antibodies to fight off infections. However, in some children, these antibodies mistakenly target the brain, particularly the basal ganglia—a part of the brain that helps control movement, emotions, and behavior.
This misdirected immune response leads to rapid-onset symptoms, including:
✔ Obsessive-compulsive disorder (OCD) behaviors – excessive handwashing, counting rituals
✔ Motor or vocal tics – blinking, throat clearing, involuntary movements
✔ Severe anxiety, panic attacks, or depression
✔ Sudden bedwetting or loss of motor skills
✔ Hyperactivity, impulsivity, and trouble concentrating
Unlike traditional mental health conditions, PANDAS symptoms appear suddenly—sometimes within hours or days—making it crucial for parents and professionals to recognize early warning signs.
How Is PANDAS Diagnosed?
There is no single test for PANDAS, but diagnosis is based on the following factors:
🩺 Sudden and severe behavior changes – especially OCD or tics
🦠 A recent strep infection – confirmed by a throat culture or blood test for strep antibodies
📈 Episodic symptoms – flare-ups that come and go
⚡ Neurological signs – small, jerky movements, trouble with coordination
Doctors may also conduct neurological exams and psychological assessments to rule out other conditions such as Tourette’s syndrome, generalized OCD, or pediatric autoimmune encephalitis.
How Is PANDAS Treated?
1. Antibiotics (First-Line Treatment)
Since PANDAS is triggered by a bacterial infection, antibiotics like amoxicillin or azithromycin are the first-line treatment. Many children show rapid improvement once the infection is treated.
2. Anti-Inflammatory Medications
Because brain inflammation plays a role in PANDAS, doctors may recommend ibuprofen (Advil) or corticosteroids to reduce swelling and ease symptoms.
3. Cognitive Behavioral Therapy (CBT) & Exposure and Response Prevention (ERP)
Behavioral therapy is essential in managing OCD symptoms, anxiety, and mood regulation. A trained CBT specialist can help children learn coping skills to manage compulsions and distress.
4. Immunotherapy (For Severe Cases)
If antibiotics and behavioral treatments don’t lead to recovery, more intensive interventions may be needed, including:
Intravenous Immunoglobulin (IVIG) – Helps reset the immune system
Plasmapheresis – Removes harmful antibodies from the blood
Why Early Treatment Matters
The sooner PANDAS is recognized and treated, the better the outcome. If left untreated, symptoms can worsen over time and lead to long-term psychiatric challenges.
💡 Many children recover fully with early intervention, proper treatment, and ongoing monitoring.

Final Thoughts
PANDAS is a serious but treatable condition. If your child suddenly develops OCD-like behaviors, motor tics, or mood swings after a strep infection, don’t wait—talk to a doctor immediately. With proper medical care and behavioral support, children with PANDAS can recover and regain their normal quality of life.
