Research Update: Exciting New Discovery About Sensory Processing Disorder

Breakthrough Study Reveals Biological Basis for Sensory Processing Disorders in Kids

Researchers at USCF have completed an important study about the biological characteristics of Sensory Processing Disorder. They matched boys with a diagnosis of SPD with typical peers, using the Sensory Profile to measure differences between the subjects. Using a form of magnetic resonance imaging called diffusion tensor imaging (DTI), they found significant differences in the white matter of the back of the brain. These differences were located in areas that are responsible for connecting the sensory systems related to auditory, visual, and tactile processing.  The changes in the brains of boys with SPD are thought to be impact the timing of sensory progressing, resulting in the difficulty integrating the input for function. Of note is the finding that the differences in the SPD brain occurred in the back of the brain, where differences in autism and ADD occur in the front of the brain.  This study is the first to uncover biological evidence of Sensory Processing Disorder as it own, distinct diagnosis.
