Increased Rate of Amygdala Growth in Children Aged 2 to 4 Years With Autism Spectrum Disorders

Abstract

Disproportionate amygdala enlargement is present by 37 months of age in ASD. The amygdala continues to grow at an increased rate, but substantial heterogeneity exists in amygdala and TCV growth patterns. Future studies aimed at clinical characterization of different growth patterns could have implications for choice and outcomes of treatment and behavioral therapy.
