What Is PANDAS?

PANDAS is a complex disorder that consists of many different symptoms unique to each patient. Learn more about what PANDAS is and how it affects the brain and body.

Pediatric autoimmune neuropsychiatric disorder associated with streptococcal infections (PANDAS) is a disorder that results from infection with streptococcal-A, commonly referred to as strep, or strep throat. Following infection with strep, children with PANDAS syndrome develop severe physical, neurological and psychological disturbances that interfere with their daily functioning. Thankfully, we can treat this disorder. In addition, we can moderate its symptoms through a professional following an accurate diagnosis.

Based on PANDAS Network research, a conservative estimate of PANDAS prevalence is 1 in 200 children in the United States alone. This is a staggering number, especially considering that many doctors, medical professionals and clinicians do not recognize PANDAS. Many children go untreated, sometimes experiencing debilitating symptoms for years until finding the cause and visiting a PANDAS specialist.

What causes PANDAS?

The root cause of PANDAS is believed to be a strep infection triggering an autoimmune disorder in certain susceptible individuals. An autoimmune disorder is when the immune system mistakenly attacks cells in the body—in essence, attacking itself. In the case of PANDAS, strep bacteria cause the immune system to attack healthy cells in the brain (specifically the basal ganglia). These result in neurological abnormalities, mental and academic regression and severe psychological problems.

Symptoms generally appear soon after a bout of strep throat. However, the initial onset of symptoms may not appear for months in certain cases. So even if your child exhibits PANDAS symptoms long after a strep infection, they could still be experiencing PANDAS.

Additional factors for developing PANDAS may be related to genetic differences. Based on 100 self-reports from families, 70% reported both autoimmune illness and strep-related severity illness in their family. More research is being done in this area to investigate genetic links between the predisposition to autoimmune disorders, strep infection and developing PANDAS.

What are some PANDAS symptoms and signs?

Just as all immune systems are different, so are the signs and symptoms of PANDAS. However, some distinguishing features of PANDAS include mood lability (rapid, often exaggerated changes in mood), tics, obsessive-compulsive behavior and the acute onset of severe anxiety. These symptoms tend to flare up, diminish and return cyclically. Symptoms can reoccur with subsequent strep infections, which PANDAS children are susceptible to becoming reinfected with repeatedly. Often a family history of rheumatic fever or other strep-related disease is noted.

PANDAS falls under the umbrella of PANS (pediatric acute-onset neuropsychiatric syndrome). Both diagnoses include the abrupt, pre-pubertal onset of obsessions, compulsions or tics. But PANDAS requires the association with streptococcal infection and PANS is associated with other infections, such as influenza or Lyme disease. Some other common symptoms of PANDAS or PANS are:

  • Tics, which can be verbal—such as grunting—or jerking of the limbs or head
  • Depression, which can lead to suicidal thoughts and behavior, uncontrollable crying or fear
  • Extreme rage or inability to control anger; breaking items and throwing objects
  • Sleep issues, including lack of sleep or excessive fatigue
  • Bedwetting
  • Restrictive eating or avoidance of food, which can cause extreme weight loss
  • Unusual gait, poor coordination or degradation of handwriting
  • OCD-like symptoms, such as repetitive actions, fear of germs or developing habits and rituals that must be followed to avoid anxiety and panic
  • Behavioral abnormalities and personality changes
  • Sensory problems, like sensitivity to light and sound
  • Academic skill deterioration and mental regression

OCD and tics are often strong indicators when considering a PANDAS/PANS diagnosis. Among parents with diagnosed children, 37% reported OCD-like symptoms, 14% reported tics and 49% reported both. In fact, it is estimated that children with PANDAS/PANS may make up as much as 25% of children diagnosed with OCD and tic disorders, such as Tourette syndrome.¹

How is PANDAS disease diagnosed?

An accurate clinical diagnosis will consider the collection of signs and symptoms, lab test results and your child’s medical history. While there is no definitive test for PANDAS at this time, your provider can use several tests, including strep cultures, allergy tests, immunological tests, brain scans and the Cunningham panel (a test that determines the likelihood that the patient’s disorder is autoimmune in nature) among others to give you a PANDAS diagnosis.

Clinical diagnostic criteria for PANDAS/PANS are specific and consist of the following:

  1. The sudden, dramatic onset of obsessive-compulsive disorder or extremely restricted food intake.
  1. The simultaneous appearance of additional neuropsychiatric symptoms with acute, severe onset from at least two of the following seven categories:
  • Irritability, aggression or oppositional behaviors
  • Motor or sensory abnormalities
  • Emotional lability or depression
  • Behavioral (developmental) regression
  • Anxiety
  • A decline in school performance
  • Somatic symptoms, such as sleep disturbances, increased urinary frequency or enuresis
  1. These symptoms are not better explained by another known medical condition or neurological disorder, such as Tourette disorder, Sydenham’s chorea or systemic lupus erythematosus.

Other medical disorders can present with signs and symptoms that are similar to PANDAS/PANS. Using various tests, your provider can help identify your child’s symptoms and rule out other psychological, neurological and medical conditions. Once your child receives a PANDAS/PANS diagnosis, they can begin treatment to target the underlying cause and get on the road to symptom relief.

How do you treat PANDAS disorder?

It is critical to treat PANDAS as soon as possible after symptoms appear. The earlier you start, the better the outcome will be. PANDAS symptoms may worsen over time without treatment. PANDAS treatment may consist of the following:

  • Antibiotics, such as penicillin, Augmentin, cephalosporins or azithromycin
  • Prophylactic antibiotics, which can reduce the recurrence of symptoms in the long term
  • IVIG, an intravenous solution comprising immunoglobulins that treat encephalitis, immune deficiencies and other immune disorders
  • Plasmapheresis, which removes harmful auto-antibodies from the blood to reduce PANDAS symptoms

You may consider other treatments in conjunction with these therapies, including tonsil removal, NSAIDs (like ibuprofen), steroids or psychological interventions such as cognitive-behavioral therapy or exposure and response therapy (ERP). Specific treatment plans will depend on your child’s symptoms, which you can discuss with your medical provider.

How long does PANDAS disorder last?

The duration of PANDAS differs between patients, the severity of symptoms and how soon you begin treatment for the condition. PANDAS generally appears in childhood. According to 700 self-reports, the ages of onset were:

  • 1-3 years: 11%
  • 4-9 years: 69%
  • 10-13 years: 19%
  • 14+ years: only 1%

According to current research, PANDAS is a pediatric disease caused by a strep infection, which is common in young children and demonstrated in these prevalence rates. PANDAS/PANS symptoms seem to flare and remit throughout childhood and disappear in adulthood with proper treatment and symptom maintenance.
