PANDAS (Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcus). This term is used to describe a subset of children who have Obsessive Compulsive Disorder (OCD) and/or tic disorders such as Tourette Syndrome, and in whom symptoms worsen following strep infections such as “Strep throat” and Scarlet Fever. The children usually have dramatic, “overnight” onset of symptoms, including motor or vocal tics, obsessions, and/or compulsions. In addition to these symptoms, children may also become moody, irritable or show concerns about separating from parents or loved ones. This abrupt onset is generally preceded by a Strep throat infection. Researchers at the NIMH are pursuing a theory that the mechanism or cause is similar to that of Rheumatic Fever, an autoimmune disorder triggered by strep throat infections.PANDAS (Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcus)[rx]
Pediatric autoimmune neuropsychiatric disorders associated with Streptococcus infections (PANDAS) is a neurological and psychiatric condition in which symptoms are brought on or worsened by a Streptococcal (strep) infection. PANDAS is a subtype of pediatric acute-onset neuropsychiatric syndrome (PANS). Signs and symptoms of PANDAS align with current guidelines for diagnosing PANDAS, and include:[1]
– The presence of obsessive-compulsive disorder (OCD) and/or tics (uncontrolled, sudden, repetitive movements or sounds), which are severe enough to interfere the ability to function.
– Symptoms appear between 3 years of age and puberty (although later onset of symptoms is possible).
– Symptoms appear abruptly and dramatically (typically within one to two days) and may repeatedly improve and then suddenly worsen (a relapsing and remitting course).
There is an association between symptom onset or worsening and a group A Streptococcal (GAS) infection. Symptom flares must be associated with a positive throat culture and/or blood tests that show elevated antibodies against a substance produced by GAS (called anti-GAS titers). Children with PANDAS often do not complain of a sore throat despite having an infection. After the initial infection, subsequent flares can be associated with other infectious or environmental triggers.
There are other neurologic abnormalities. When symptoms of PANDAS are present, a neurological exam will be abnormal. Abnormalities may include any of the additional neuropsychiatric symptoms that occur in people with PANS.
The underlying cause of PANDAS is unclear, but studies suggest that a strep infection causes an abnormal immune response resulting in neuropsychiatric symptoms. Management is centered on providing antibiotics for GAS infection, and medication or behavioral therapy for neuropsychiatric symptoms.[2][3]
Types of PANDAS (Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcus Infections):
- Classic PANDAS: This is the most common type and is characterized by sudden and severe symptom onset.
- PANDAS Variant: In this type, symptoms are not as sudden as in classic PANDAS, and other infections besides streptococcus can trigger the condition.
Causes of PANDAS:
- Streptococcus Infections: PANDAS is primarily triggered by streptococcus infections, such as strep throat. When the body fights off streptococcus, the immune response may mistakenly attack brain cells, leading to PANDAS.
- Genetic Factors: Some children may have a genetic predisposition that makes them more susceptible to developing PANDAS when exposed to streptococcus.
- Environmental Factors: Environmental factors could also play a role in the development of PANDAS, though research is ongoing in this area.
Symptoms of PANDAS:
PANDAS can manifest with a variety of symptoms. Here are some common ones:
- Tics: Sudden, repetitive movements or vocalizations.
- Obsessive-Compulsive Symptoms: Children may develop obsessive thoughts and engage in repetitive behaviors.
- Anxiety: Increased anxiety levels, including separation anxiety.
- Emotional Changes: Mood swings, irritability, and aggression.
- Sudden Decline in School Performance: Difficulty concentrating, writing, or performing tasks they previously could.
- Sleep Disturbances: Trouble falling asleep or staying asleep.
- Eating Changes: Selective eating habits or food aversions.
- Urinary Frequency: Frequent urination or bedwetting.
- Sensory Sensitivities: Heightened sensitivity to light, noise, or textures.
- Handwriting Regression: A sudden decline in handwriting skills.
Diagnostic Tests for PANDAS:
- Throat Swab: To check for current streptococcus infection.
- Blood Tests: To look for specific antibodies associated with PANDAS.
- Neuropsychological Assessment: This evaluates cognitive and emotional functioning.
- Behavioral Assessments: Observations of behavior changes over time.
- Brain Imaging: MRI or CT scans may be used to rule out other conditions.
Treatments for PANDAS:
- Antibiotics: If a streptococcus infection is present, antibiotics like penicillin or amoxicillin can help clear the infection and reduce symptoms.
- Anti-Inflammatory Medications: Non-steroidal anti-inflammatory drugs (NSAIDs) can help reduce inflammation and relieve symptoms.
- Behavioral Therapy: Psychotherapy can help children manage their symptoms and develop coping strategies.
- Cognitive-Behavioral Therapy (CBT): CBT can be effective in treating obsessive-compulsive symptoms.
- Immune Therapy: Intravenous immunoglobulin (IVIG) and plasmapheresis are options to modulate the immune response.
- Supportive Care: Providing a stable, supportive environment is crucial for a child with PANDAS.
- Dietary Changes: Some children may benefit from dietary modifications, such as gluten-free or dairy-free diets.
- Stress Reduction: Stress management techniques, like mindfulness and relaxation exercises, can be helpful.
- Education and Advocacy: Parents and caregivers should educate themselves about PANDAS and advocate for their child’s needs at school and in healthcare settings.
Commonly Used Drugs for PANDAS:
- Penicillin: An antibiotic often used to treat streptococcus infections.
- Amoxicillin: Another antibiotic effective against streptococcus.
- Ibuprofen: A commonly used NSAID to reduce inflammation and alleviate pain.
- Prednisone: A corticosteroid that can help reduce inflammation.
- Selective Serotonin Reuptake Inhibitors (SSRIs): Sometimes prescribed to manage anxiety and obsessive-compulsive symptoms.
- IVIG (Intravenous Immunoglobulin): Used to modulate the immune system.
Conclusion:
Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcus Infections (PANDAS) can be a challenging condition for both children and their families. However, with early diagnosis and appropriate treatment, many children with PANDAS can experience significant improvement in their symptoms and quality of life. If you suspect your child may have PANDAS, it’s essential to consult with a healthcare professional who can provide guidance and support tailored to your child’s specific needs.
