What Is PANDAS?PANDAS, or P.A.N.D.A.S., is short for Pediatric AutoImmune Neuropsychiatric Disorders Associated with Streptococcal Infections. PANDAS is hypothesized to be caused by strep bacteria, which can hide from a child’s immune system by mimicking healthy cells in the skin, heart, joints, and brain tissue. Children with PANDAS experience a sudden onset or worsening of tics and/or Obsessive-Compulsive Disorder (OCD). While many children may experience strep throat, OCD, or tics, PANDAS is diagnosed when there is a close relationship found between the onset/severity of these symptoms and a streptococcal infection.
