Abstract
Functional magnetic resonance imaging, or fMRI, has been shown to be helpful for the study of autism spectrum disorders, or ASD. This talk will describe the evolution of efforts in this area that carry promise for producing objective biomarkers for ASD from both resting-state and talk-based fMRI, as well as predicting patient response to a behavioral therapy known as Pivotal Response Treatment, or PRT, from baseline task-based fMRI. Such biomarkers would provide an important step in better understanding the underlying pathophysiology of ASD.
Patient response prediction could help with objective and personalized diagnosis. First, early image analysis efforts will be described that were based on estimating connected subnetwork membership using multi-view (structural and functional) MRI data. Next, more recent work based on data-driven (deep) learning will be presented that has focused on deriving ASD biomarkers from both resting-state and task-based functional connectivity measures. Finally, two approaches will be presented that predict patient response to PRT behavioral therapy, guided by the above-mentioned biomarkers.
