PANS (Pediatric Acute-onset Neuropsychiatric Syndrome) and PANDAS (Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal Infection) are conditions that can lead to the sudden psychiatric symptoms in children. The conditions are triggered by an infection. The PANDAS Network* describes PANS as when “a misdirected immune response results in inflammation on a child’s brain. In turn, the child quickly begins to exhibit life changing symptoms such as OCD, severe restrictive eating, anxiety, tics, personality changes, decline in math and handwriting abilities, sensory sensitivities, and more.”
