چکیده

Frontostriatal and frontoamygdalar connectivity alterations in patients with obsessive-compulsive disorder (ocd) have been typically described in functional neuroimaging studies. however,structural covariance,or volumetric correlations across distant brain regions,also provides network-level information. altered structural covariance has been described in patients with different psychiatric disorders,including ocd,but to our knowledge,alterations within frontostriatal and frontoamygdalar circuits have not been explored. methods: we performed a mega-analysis pooling structural mri scans from the obsessive-compulsive brain imaging consortium and assessed whole-brain voxel-wise structural covariance of 4 striatal regions (dorsal and ventral caudate nucleus,and dorsal-caudal and ventral-rostral putamen) and 2 amygdalar nuclei (basolateral and centromedial-superficial). images were preprocessed with the standard pipeline of voxel-based morphometry studies using statistical parametric mapping software. results: our analyses involved 329 patients with ocd and 316 healthy controls. patients showed increased structural covariance between the left ventral-rostral putamen and the left inferior frontal gyrus/frontal operculum region. this finding had a significant interaction with age; the association held only in the subgroup of older participants. patients with ocd also showed increased structural covariance between the right centromedial-superficial amygdala and the ventromedial prefrontal cortex. limitations: this was a cross-sectional study. because this is a multisite data set analysis,participant recruitment and image acquisition were performed in different centres. most patients were taking medication,and treatment protocols differed across centres. conclusion: our results provide evidence for structural network-level alterations in patients with ocd involving 2 frontosubcortical circuits of relevance for the disorder and indicate that structural covariance contributes to fully characterizing brain alterations in patients with psychiatric disorders. © 2016 8872147 canada inc.
