Connery K, et al. - As children with autism spectrum disorder (ASD) may manifest brain autoantibodies, researchers screened patients in an ASD clinic who did not respond to standard interventions for autoimmune encephalopathy (AIE). Majority of these patients showed symptom improvements in association with IVIG treatment. Although adverse effects were experienced by a majority of patients, these were mostly limited to the time around the IVIG infusion, resulting in the great majority of patients considering that the benefits outweigh any adverse effects.
