PANDAS (Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal Infections) and PANS (Pediatric Acute-onset Neuropsychiatric Syndrome)

Description:

PANDAS is short for Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal Infections. A child may be diagnosed with PANDAS when:

  • Obsessive compulsive disorder (OCD) and/or tic disorders suddenly appear following a strep infection (such as strep throat or scarlet fever); or
  • The symptoms of OCD or tic symptoms suddenly become worse following a strep infection.

The symptoms are usually dramatic, happen “overnight and out of the blue,” and can include motor and/or vocal tics, obsessions, and/or compulsions. In addition to these symptoms, children may also become moody, irritable, experience anxiety attacks, or show concerns about separating from parents or loved ones.

The diagnosis of PANDAS is a clinical diagnosis, which means that there are no lab tests that can diagnose PANDAS. Instead, clinicians use 5 diagnostic criteria for the diagnosis of PANDAS (see below). At the present time the clinical features of the illness are the only means of determining whether or not a child might have PANDAS.

The diagnostic criteria are:

  • Presence of obsessive-compulsive disorder and/or a tic disorder
  • Pediatric onset of symptoms (age 3 years to puberty)
  • Episodic course of symptom severity
  • Association with group A Beta-hemolytic streptococcal infection (a positive throat culture for strep or history of scarlet fever)
  • Association with neurological abnormalities (physical hyperactivity, or unusual, jerky movements that are not in the child’s control)
  • Very abrupt onset or worsening of symptoms

The best treatment for acute episodes of PANDAS is to treat the strep infection causing the symptoms (if it is still present) with antibiotics.

  • A throat culture should be done to document the presence of strep bacteria in the throat (oropharynx).
  • If the throat culture is positive, a single course of antibiotics will usually get rid of the strep infection and allow the PANDAS symptoms to subside.
