This study aimed to identify all the common neural substrates with connectomic abnormalities across four major psychiatric disorders by using the data-driven connectome-wide association method of multivariate distance matrix regression (MDMR).<\/jats:p>\n\t  <\/jats:sec>\n\t  <jats:sec id=\"S0924933820001066_sec2\" sec-type=\"methods\">\n\t    <jats:title>Methods<\/jats:title>\n\t    <jats:p>This study analyzed a resting functional magnetic resonance imaging dataset of 100 patients with schizophrenia, 100 patients with bipolar I disorder, 100 patients with bipolar II disorder, 100 patients with major depressive disorder, and 100 healthy controls (HCs). We calculated a voxel-wise 4,330\u00a0\u00d7\u00a04,330 matrix of whole-brain functional connectivity (FC) with 8-mm isotropic resolution for each participant and then performed MDMR to identify structures where the overall multivariate pattern of FC was significantly different between each patient group and the HC group. A conjunction analysis was performed to identify common neural regions with FC abnormalities across these four psychiatric disorders.<\/jats:p>\n\t  <\/jats:sec>\n\t  <jats:sec id=\"S0924933820001066_sec3\" sec-type=\"results\">\n\t    <jats:title>Results<\/jats:title>\n\t    <jats:p>The conjunction of the MDMR maps revealed that the four groups of patients shared connectomic abnormalities in distributed cortical and subcortical structures, which included bilateral thalamus, cerebellum, frontal pole, supramarginal gyrus, postcentral gyrus, lingual gyrus, lateral occipital cortex, and parahippocampus. The follow-up analysis based on pair-wise FC of these regions demonstrated that these psychiatric disorders also shared similar patterns of FC abnormalities characterized by sensory\/subcortical hyperconnectivity, association\/subcortical hypoconnectivity, and sensory\/association hyperconnectivity.<\/jats:p>\n\t  <\/jats:sec>\n\t  <jats:sec id=\"S0924933820001066_sec4\"
