Living with PANDAS

A childhood condition in which strep infections trigger or worsen sudden OCD-like behaviors or tics.

Understanding PANDAS

PANDAS is a brain and behavior condition in which symptoms begin or flare after a strep infection.

The name stands for pediatric autoimmune neuropsychiatric disorders associated with Streptococcus infections. Main symptoms are obsessive-compulsive behavior (OCD) and tics, which are sudden, repeated movements or sounds, and they can be severe enough to disrupt daily life. GARD says the cause is unclear, but strep may trigger an abnormal immune response. It is a subtype of PANS.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Obsessive-compulsive behavior (OCD)
  • Tics (sudden, repeated movements or sounds)
  • Irritability and mood swings
  • Trouble sleeping
  • Attention and impulsivity problems
  • Loss of skills already learned (developmental regression)

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include brain and nervous system specialists.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.

  4. Connect with expert centers

    Autoimmune Association, ASPIRE and Neuroimmune Foundation may keep lists of experts for this condition.

The cause is unclear. GARD says studies suggest a strep infection triggers an abnormal immune response that leads to the symptoms.
