Topic: Neural Differences in Developmental Stuttering: New Evidence from Quantitative Imaging
Developmental stuttering is characterized by fluency differences including blocks, prolongations, and repetitions. Theoretical accounts implicate dysfunctional cortico-striatal-thalamo-cortical motor loops through the putamen, but empirical evidence is currently limited. Conventional MRI contrasts are sensitive to the size of grey matter structures and diffusion properties in white matter, whereas quantitative MRI can provide detailed maps of microstructural properties of brain tissue in both grey and white matter. Here we will present results of analyzing these quantitative maps in a large cohort of people who stutter and matched controls. Microstructural differences in relevant cortical and subcortical regions may provide key evidence to support theoretical models of stuttering. These differences will ideally open up new avenues for understanding the causes and correlates of stuttering, in addition to treatment for those who may want it.
