Are schizophrenia, autistic, and obsessive spectrum disorders dissociable on the basis of neuroimaging morphological findings?: A voxel-based meta-analysis / Franco CAUDA in Autism Research, 10-6 (June 2017)
[article]
Titre : Are schizophrenia, autistic, and obsessive spectrum disorders dissociable on the basis of neuroimaging morphological findings?: A voxel-based meta-analysis Type de document : Texte imprimé et/ou numérique Auteurs : Franco CAUDA, Auteur ; Tommaso COSTA, Auteur ; Andrea NANI, Auteur ; Luciano FAVA, Auteur ; Sara PALERMO, Auteur ; Francesca BIANCO, Auteur ; Sergio DUCA, Auteur ; Karina TATU, Auteur ; Roberto KELLER, Auteur Article en page(s) : p.1079-1095 Langues : Anglais (eng) Mots-clés : brain alterations neuroimaging schizophrenia spectrum disorder autism spectrum disorder obsessive-compulsive spectrum disorder psychiatric categories core alterations Index. décimale : PER Périodiques Résumé : Schizophrenia spectrum disorder (SCZD), autism spectrum disorder (ASD), and obsessive-compulsive spectrum disorder (OCSD) are considered as three separate psychiatric conditions with, supposedly, different brain alterations patterns. From a neuroimaging perspective, this meta-analytic study aimed to address whether this nosographical differentiation is actually supported by different brain patterns of gray matter (GM) or white matter (WM) morphological alterations. We explored two possibilities: (a) to find out whether GM alterations are specific for SCZD, ASD, and OCSD; and (b) to associate the identified brain alteration patterns with cognitive dysfunctions by means of an analysis of lesion decoding. Our analysis reveals that these psychiatric spectra do not present clear distinctive patterns of alterations; rather, they all tend to be distributed in two alteration clusters. Cluster 1, which is more specific for SCZD, includes the anterior insular, anterior cingulate cortex, ventromedial prefrontal cortex, and frontopolar areas, which are parts of the cognitive control system. Cluster 2, which is more specific for OCSD, presents occipital, temporal, and parietal alteration patterns with the involvement of sensorimotor, premotor, visual, and lingual areas, thus forming a network that is more associated with the auditory-visual, auditory, premotor visual somatic functions. In turn, ASD appears to be uniformly distributed in the two clusters. The three spectra share a significant set of alterations. Our new approach promises to provide insight into the understanding of psychiatric conditions under the aspect of a common neurobiological substrate, possibly related to neuroinflammation during brain development.
