What is PANS/PANDAS?
P.A.N.D.A.S. (Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal Infections) and P.A.N.S. (Pediatric Acute-onset Neuropsychiatric Syndrome) are terms used to describe a subset of children and adolescents who experience an encephalitic-like onset of neuropsychiatric symptoms following an infection such as Strep, Pneumonia, Lyme, Mycoplasma, Mononucleosis, and more.
In simple terms, antibodies created to fight the infection become misdirected and attack a small area of the brain known as the basal ganglia. This autoimmune reaction results in an acute onset of neuropsychiatric symptoms that can include: separation anxiety, OCD, severe eating restriction, tics, age regression, sleep difficulties, personality changes, urinary frequency, irritability, rage, sensory sensitivities, and deterioration in learning abilities.
