PANDAS, or Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal Infections, is a rare condition that sometimes follows a strep infection. It is characterised by sudden changes in mood and behaviour, with children experiencing symptoms such as obsessive-compulsive behaviours, tics, and mood swings. PANDAS is typically first observed in children between the ages of 3 and 12, with cases in adolescents and adults being extremely rare. The condition is believed to be triggered by an autoimmune response to a streptococcal infection, such as strep throat or scarlet fever, which results in the body attacking its own healthy brain tissue.

PANDAS is an abbreviation for Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal Infections
PANDAS is a subset of PANS (Pediatric Acute-onset Neuropsychiatric Syndrome), a clinically defined disorder characterised by the sudden onset of obsessive-compulsive symptoms (OCD) or eating restrictions, along with acute behavioural deterioration in at least two designated domains. PANDAS is the only subtype of PANS that requires that symptoms be associated with a strep infection. The symptoms of PANDAS include obsessive thoughts, compulsive behaviours, and motor or vocal tics. Children with PANDAS often experience one or more of the following symptoms in conjunction with their OCD or tic disorder: symptoms of attention-deficit/hyperactivity disorder (ADHD), such as hyperactivity, inattention, or fidgeting; separation anxiety; mood changes, such as irritability, sadness, or emotional lability; and aggressive behaviour.
The underlying cause of PANDAS is thought to be attributed to an autoimmune attack of healthy brain tissue after a strep infection. During a Group A Streptococcal (strep) bacterial infection, our immune system creates antibodies and strep-specific T-cells to destroy the invading bacteria. In some instances, the antibodies that are made during the adaptive immune response inadvertently target the child’s own healthy tissue in the brain. It is also possible that some people are genetically predisposed to these forms of dysregulated immune response.
PANDAS is diagnosed by a healthcare provider after evaluating the patient. Although laboratory testing cannot identify PANDAS, it might identify a Group A Strep infection, which precedes PANDAS. If a Group A Strep infection is identified, antibiotics might be prescribed to kill the bacteria. Other treatments might be provided based on the patient’s clinical condition, including cognitive behavioural therapy or anti-obsessional medications.

It is a type of pediatric acute-onset neuropsychiatric syndrome (PANS)
PANDAS syndrome, or Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal Infections, is a type of pediatric acute-onset neuropsychiatric syndrome (PANS). PANS is a broader group of autoimmune diseases that can affect a child's brain. PANDAS is triggered by a streptococcal infection, such as strep throat, peri-anal strep, or scarlet fever.
PANS is a newly described clinical entity with a heterogeneous symptom presentation. It is characterised by the acute or subacute onset of obsessive-compulsive disorder (OCD) and/or a severe food intake restriction, associated with at least two cognitive, behavioural, or affective symptoms such as irritability, anxiety or depression. The symptoms of PANS are similar to those of PANDAS but may be triggered by something other than strep.
PANDAS is considered a paediatric disorder and typically first appears in childhood from age 3 to puberty. It is rare for children older than 12 to have reactions to strep infections, but researchers recognise that PANDAS could occur, though rarely, among adolescents. It is unlikely that someone would experience these post-strep neuropsychiatric symptoms for the first time as an adult, but it has not been fully studied.
PANDAS is considered a diagnosis when there is a very close relationship between the abrupt onset or worsening of OCD, tics, or both, and a strep infection. The symptoms of OCD or tic symptoms suddenly become worse following a strep infection. The symptoms are usually dramatic, happening "overnight and out of the blue". Children with PANDAS often experience one or more of the following symptoms in conjunction with their OCD or tic disorder: symptoms of attention-deficit/hyperactivity disorder (ADHD), such as hyperactivity, inattention, or fidgeting; separation anxiety; and mood changes, such as irritability, sadness, or emotional lability.
PANS is a clinical diagnosis given to children who have a dramatic – sometimes overnight – onset of neuropsychiatric symptoms. PANS can be codified using the DSM-5 diagnosis of "Obsessive-Compulsive and Related Disorder Due to Another Medical Condition".

PANDAS is considered a pediatric disorder and typically first appears in childhood from age 3 to puberty
PANDAS, or pediatric autoimmune neuropsychiatric disorders associated with streptococcal infections, is a rare paediatric disorder that typically affects children between the ages of 3 and 12. While it can occur in older children and adolescents, it is rare for those over the age of 12 to experience reactions to strep infections.
PANDAS is characterised by the sudden onset or worsening of obsessive-compulsive disorder (OCD), tic disorders, or both, following a streptococcal (strep) infection such as strep throat or scarlet fever. The symptoms of PANDAS are typically dramatic and can include motor or vocal tics, obsessions, compulsions, mood changes, anxiety, and separation anxiety.
The underlying cause of PANDAS is believed to be an autoimmune response, where the body's immune system attacks its own healthy brain tissue after a strep infection. This response is thought to be triggered by specific strains of Group A Streptococcal (GAS) bacteria, which can produce post-infectious sequelae such as PANDAS. However, the mechanism behind this disorder is still not fully understood and is a subject of ongoing research.
The diagnosis of PANDAS is based on clinical evaluation and diagnostic criteria, as there are no specific laboratory tests available for confirmation. Healthcare providers consider the patient's signs and symptoms, medical history, and laboratory test results to make a diagnosis. Treatment for PANDAS typically involves medication and therapy, including antibiotics to treat the underlying strep infection and anti-inflammatories to calm the immune system.

PANDAS is a controversial diagnosis, with no definitive test for diagnosis
PANDAS, or pediatric autoimmune neuropsychiatric disorders associated with streptococcal infections, is a controversial diagnosis. There is no definitive test for PANDAS, and the condition remains unproven. Instead, healthcare providers must rely on diagnostic criteria and clinical features to determine whether a patient has PANDAS.
PANDAS is a subset of PANS (paediatric acute-onset neuropsychiatric syndrome), a clinically defined disorder characterised by the sudden onset of obsessive-compulsive symptoms (OCD) or restricted food intake, along with acute behavioural deterioration and severe neuropsychiatric symptoms. PANDAS is differentiated from PANS by its requirement for symptoms to be associated with a streptococcal infection.
The PANDAS hypothesis suggests that the syndrome is an autoimmune disorder triggered by a Group A Streptococcal (strep) bacterial infection. In some instances, the antibodies produced during the adaptive immune response may target a child's own healthy tissue in the brain. This can result in dramatic mood changes, tics, obsessive-compulsive behaviour, and the sudden onset of intense anxiety.
PANDAS is typically first diagnosed in childhood, from ages 3 to 12, although it can affect older children and, very rarely, adults. The symptoms of PANDAS are usually dramatic and can include motor or vocal tics, obsessions, compulsions, mood changes, anxiety, and severe separation anxiety. The symptoms may appear "overnight and out of the blue" and can be cyclical, with periods of remission.
While there is no definitive test for PANDAS, healthcare providers can use several tests to support a diagnosis, including strep cultures, allergy tests, immunological tests, brain scans, and the Cunningham panel. An elevated anti-strep antibody titre, for example, can indicate that a child has had a previous strep infection. However, the diagnostic criteria for PANDAS are unevenly applied, and the condition may be overdiagnosed or misdiagnosed due to the difficulty in locating the strep trigger.

Treatment for PANDAS is generally the same as the standard treatments for Tourette syndrome and OCD
PANDAS, or Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal Infections, is a controversial hypothesis for a subset of children who exhibit a rapid onset of obsessive-compulsive disorder (OCD) or tic disorders following a streptococcal infection. While there is no definitive test for PANDAS, healthcare providers use various diagnostic criteria, including clinical features, lab test results, and medical history, to determine if a child may have PANDAS.
Treatment for PANDAS typically involves medication and therapy, similar to the standard treatments for Tourette syndrome and OCD. Antibiotics are often used to treat the underlying strep infection, and anti-inflammatories, such as steroid pills, are administered to calm the immune system. Cognitive behavioural therapy (CBT) can also be beneficial in helping children manage the mental and emotional challenges associated with PANDAS.
It is important to note that the treatment plans for PANDAS and Tourette syndrome differ, and a misdiagnosis can be harmful. While antibiotics can reduce or resolve PANDAS symptoms, they do not have the same effect on Tourette syndrome. This distinction highlights the need for accurate diagnosis and tailored treatment plans for each condition.
Additionally, the treatment for PANDAS-related immune issues and inflammation can vary depending on symptom severity. Treatment options can include NSAIDs, IV steroids, IVIG, or other immune-modifying medications. The goal is to address the dysregulated immune system and reduce inflammation, which can contribute to the symptoms experienced by children with PANDAS.
Overall, early treatment for PANDAS is crucial to prevent possible long-term complications and to improve the chances of symptom relief. By working closely with healthcare professionals, parents can ensure their children receive the best care and improve their chances of making a full recovery.
