Cerebellar role in Social Anxiety Disorder (SAD) remains yet to be explored using resting state functional connectivity MRI (fcMRI). Here, we are investigating additional neuronal pathways in a patient population with SAD. Compared to healthy controls, we report hyper-connectivity in left amygdala in the medication nave patient group. Furthermore, significantly stronger temporal correlations revealed between cerebellar seeds and amygdala in the patient group, underscore the involvement of cerebellum in SAD, which could subsequently serve as guidelines for treatment.
