Sensory processing disorders (SPD) affect 5-16% of school-aged children, and can cause downstream deficits of intellectual and social development. In this study, we use diffusion tensor imaging to study a cohort of 41 children with SPD and 41 typically developing children ages 8-12. We confirm and generalize results from our prior pilot study indicating disrupted posterior white matter in SPD, and further demonstrate a relationship between direct measurements of tactile and non-linguistic auditory function and white matter microstructure -- not just in SPD, but also in typically developing children.
