We also know that the brain is shaped by nurturing and adverse socio-environmental experiences. Therefore, unequal exposure to harsher conditions for women compared to men in gender-unequal countries might be reflected in differences in their brain structure, and this could be the neural mechanism partly explaining women's worse outcomes in gender-unequal countries. We examined this through a random-effects meta-analysis on cortical thickness and surface area differences between adult healthy men and women, including a meta-regression in which country-level gender inequality acted as an explanatory variable for the observed differences. A total of 139 samples from 29 different countries, totaling 7,876 MRI scans, were included. Thickness of the right hemisphere, and particularly the right caudal anterior cingulate, right medial orbitofrontal, and left lateral occipital cortex, presented no differences or even thicker regional cortices in women compared to men in gender-equal countries, reversing to thinner cortices in countries with greater gender inequality. These results point to the potentially hazardous effect of gender inequality on women's brains and provide initial evidence for neuroscience-informed policies for gender equality.
- Differential prefrontal gray matter correlates of treatment response to fluoxetine or cognitive-behavioral therapy in obsessive-compulsive disorder(2013) HOEXTER, Marcelo Q.; DOUGHERTY, Darin D.; SHAVITT, Roseli G.; D'ALCANTE, Carina C.; DURAN, Fabio L. S.; LOPES, Antonio C.; DINIZ, Juliana B.; BATISTUZZO, Marcelo C.; EVANS, Karleyton C.; BRESSAN, Rodrigo A.; BUSATTO, Geraldo F.; MIGUEL, Euripedes C.Nearly one-third of patients with obsessive-compulsive disorder (OCD) fail to respond to adequate therapeutic approaches such as serotonin reuptake inhibitors and/or cognitive-behavioral therapy (CBT). This study investigated structural magnetic resonance imaging (MRI) correlates as potential pre-treatment brain markers to predict treatment response in treatment-naive OCD patients randomized between trials of fluoxetine or CBI Treatment-naive OCD patients underwent structural MRI scans before randomization to a 12-week clinical trial of either fluoxetine or group-based CBT. Voxel-based morphometry was used to identify correlations between pretreatment regional gray matter volume and changes in symptom severity on the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS). Brain regional correlations of treatment response differed between treatment groups. Notably, symptom improvement in the fluoxetine treatment group (n=14) was significantly correlated with smaller pretreatment gray matter volume within the right middle lateral orbitofrontal cortex (OFC), whereas symptom improvement in the CBT treatment group (n=15) was significantly correlated with larger pretreatment gray matter volume within the right medial prefrontal cortex (mPFC). No significant a priori regional correlations of treatment response were identified as common between the two treatment groups when considering the entire sample (n=29). These findings suggest that pretreatment gray matter volumes of distinct brain regions within the lateral OFC and mPFC were differentially correlated to treatment response to fluoxetine versus CBT in OCD patients. This study further implicates the mPFC in the fear/anxiety extinction process and stresses the importance of lateral portions of the OFC in mediating fluoxetine's effectiveness in OCD.

The possible impacts of these regional alterations in terms of structural network effects have not previously been characterized. Inter-regional morphological covariance analysis can capture network connectivity between different cortical areas at the macroscale level. Here, we used cortical thickness data from 1455 individuals with ASD and 1560 controls, across 43 independent datasets of the ENIGMA consortium's ASD Working Group, to assess hemispheric asymmetries of intra-individual structural covariance networks, using graph theory-based topological metrics. Compared with typical features of small-world architecture in controls, the ASD sample showed significantly altered average asymmetry of networks involving the fusiform, rostral middle frontal, and medial orbitofrontal cortex, involving higher randomization of the corresponding right-hemispheric networks in ASD. A network involving the superior frontal cortex showed decreased right-hemisphere randomization. Based on comparisons with meta-analyzed functional neuroimaging data, the altered connectivity asymmetry particularly affected networks that subserve executive functions, language-related and sensorimotor processes. These findings provide a network-level characterization of altered left-right brain asymmetry in ASD, based on a large combined sample. Altered asymmetrical brain development in ASD may be partly propagated among spatially distant regions through structural connectivity.
- Structural Brain Changes as Biomarkers and Outcome Predictors in Patients with Late-Life Depression: A CrossSectional and Prospective Study(2013) RIBEIZ, Salma R. I.; DURAN, Fabio; OLIVEIRA, Melaine C.; BEZERRA, Diana; CASTRO, Claudio Campi; STEFFENS, David C.; BUSATTO FILHO, Geraldo; BOTTINO, Cassio M. C.The relationship between structural changes in grey matter and treatment response in patients with late-life depression remains an intriguing area of research. This magnetic resonance imaging (MRI) study compares the baseline grey matter volume of elderly people with and without major depression (according to the DSM-IV-TR criteria) and assesses its association with antidepressant treatment response. Brain MRI scans were processed using statistical parametric mapping and voxel-based morphometry. The sample consisted of 30 patients with depression and 22 healthy controls. We found a significant volumetric reduction in the orbitofrontal cortex bilaterally in patients in comparison with controls. According to their remission status after antidepressant treatment, patients were classified as remitted or not remitted. Compared with controls, remitted patients showed a volumetric reduction in the orbitofrontal cortex bilaterally and in another cluster in the right middle temporal pole. Non-remitted patients showed an even greater volumetric reduction in the orbitofrontal cortex bilaterally compared with controls. To investigate predictive factors of remission after antidepressant treatment, we used a logistic regression. Both baseline Mini Mental State Examination score and baseline left superior lateral orbitofrontal cortex volume (standardized to the total grey matter volume) were associated with remission status. Our findings support the use of regional brain atrophy as a potential biomarker for depression. In addition, baseline cognitive impairment and regional grey matter abnormalities predict antidepressant response in patients with late-life depression.
- Whole-exome sequencing in obsessive-compulsive disorder identifies rare mutations in immunological and neurodevelopmental pathways(2016) CAPPI, C.; BRENTANI, H.; LIMA, L.; SANDERS, S. J.; ZAI, G.; DINIZ, B. J.; REIS, V. N. S.; HOUNIE, A. G.; ROSARIO, M. Conceicao do; MARIANI, D.; REQUENA, G. L.; PUGA, R.; SOUZA-DURAN, F. L.; SHAVITT, R. G.; PAULS, D. L.; MIGUEL, E. C.; FERNANDEZ, T. V.Studies of rare genetic variation have identified molecular pathways conferring risk for developmental neuropsychiatric disorders. To date, no published whole-exome sequencing studies have been reported in obsessive-compulsive disorder (OCD). We sequenced all the genome coding regions in 20 sporadic OCD cases and their unaffected parents to identify rare de novo (DN) single-nucleotide variants (SNVs). The primary aim of this pilot study was to determine whether DN variation contributes to OCD risk. To this aim, we evaluated whether there is an elevated rate of DN mutations in OCD, which would justify this approach toward gene discovery in larger studies of the disorder. Furthermore, to explore functional molecular correlations among genes with nonsynonymous DN SNVs in OCD probands, a protein-protein interaction (PPI) network was generated based on databases of direct molecular interactions. We applied Degree-Aware Disease Gene Prioritization (DADA) to rank the PPI network genes based on their relatedness to a set of OCD candidate genes from two OCD genome-wide association studies (Stewart et al., 2013; Mattheisen et al., 2014). In addition, we performed a pathway analysis with genes from the PPI network. The rate of DN SNVs in OCD was 2.51 x 10(-8) per base per generation, significantly higher than a previous estimated rate in unaffected subjects using the same sequencing platform and analytic pipeline. Several genes harboring DN SNVs in OCD were highly interconnected in the PPI network and ranked high in the DADA analysis. Nearly all the DN SNVs in this study are in genes expressed in the human brain, and a pathway analysis revealed enrichment in immunological and central nervous system functioning and development. The results of this pilot study indicate that further investigation of DN variation in larger OCD cohorts is warranted to identify specific risk genes and to confirm our preliminary finding with regard to PPI network enrichment for particular biological pathways and functions.
- Cognitive and Brain Activity Changes After Mnemonic Strategy Training in Amnestic Mild Cognitive Impairment: Evidence From a Randomized Controlled Tria(2018) SIMON, Sharon S.; HAMPSTEAD, Benjamin M.; NUCCI, Mariana P.; DURAN, Fabio L. S.; FONSECA, Luciana M.; MARTINO, Maria da Graca M.; AVILA, Renata; PORTO, Fabio H. G.; BRUCKI, Sonia M. D.; MARTINS, Camila B.; TASCONE, Lyssandra S.; JR, Edson Amaro; BUSATTO, Geraldo F.; BOTTINO, Cassio M. C.Background: Mnemonic strategy training (MST) has been shown to improve cognitive performance in amnestic mild cognitive impairment (a-MCI), however, several questions remain unresolved. The goal of the present study was to replicate earlier pilot study findings using a randomized controlled design and to evaluate transfer effects and changes in brain activation. Methods: Thirty patients with a-MCI were randomized into MST or education program. At baseline, participants completed clinical and neuropsychological assessments as well as structural and functional magnetic resonance imaging (fMRI). Interventions were administered individually and comprised four sessions, over 2 weeks. MST taught patients to use a three-step process to learn and recall face-name associations. Post-treatment assessment included fMRI, a separate face-name association task, neuropsychological tests, and measures of metamemory. Behavioral (i.e., non-fMRI) measures were repeated after one and 3-months. Results: Participants in the MST condition showed greater improvement on measures of face-name memory, and increased associative strategy use; effects that were accompanied by increased fMRI activation in the left anterior temporal lobe. While all participants reported greater contentment with their everyday memory following intervention, only the MST group reported significant improvements in their memory abilities. There was no clear indication of far-transfer effects to other neuropsychological tests. Conclusion: Results demonstrate that patients with a-MCI not only show stimulus specific benefits of MST, but that they appear capable of transferring training to at least some other cognitive tasks. MST also facilitated the use of brain regions that are involved in face processing, episodic and semantic memory, and social cognition, which are consonant with the cognitive processes engaged by training.
- Altered structural brain asymmetry in autism spectrum disorder in a study of 54 datasets(2019) POSTEMA, Merel C.; ROOIJ, Daan van; ANAGNOSTOU, Evdokia; ARANGO, Celso; AUZIAS, Guillaume; BEHRMANN, Marlene; BUSATTO FILHO, Geraldo; CALDERONI, Sara; CALVO, Rosa; DALY, Eileen; DERUELLE, Christine; MARTINO, Adriana Di; DINSTEIN, Ilan; DURAN, Fabio Luis S.; DURSTON, Sarah; ECKER, Christine; EHRLICH, Stefan; FAIR, Damien; FEDOR, Jennifer; FENG, Xin; FITZGERALD, Jackie; FLORIS, Dorothea L.; FREITAG, Christine M.; GALLAGHER, Louise; GLAHN, David C.; GORI, Ilaria; HAAR, Shlomi; HOEKSTRA, Liesbeth; JAHANSHAD, Neda; JALBRZIKOWSKI, Maria; JANSSEN, Joost; KING, Joseph A.; KONG, Xiang Zhen; LAZARO, Luisa; LERCH, Jason P.; LUNA, Beatriz; MARTINHO, Mauricio M.; MCGRATH, Jane; MEDLAND, Sarah E.; MURATORI, Filippo; MURPHY, Clodagh M.; MURPHY, Declan G. M.; O'HEARN, Kirsten; ORANJE, Bob; PARELLADA, Mara; PUIG, Olga; RETICO, Alessandra; ROSA, Pedro; RUBIA, Katya; SHOOK, Devon; TAYLOR, Margot J.; TOSETTI, Michela; WALLACE, Gregory L.; ZHOU, Fengfeng; THOMPSON, Paul M.; FISHER, Simon E.; BUITELAAR, Jan K.; FRANCKS, ClydeAltered structural brain asymmetry in autism spectrum disorder (ASD) has been reported. However, findings have been inconsistent, likely due to limited sample sizes. Here we investigated 1,774 individuals with ASD and 1,809 controls, from 54 independent data sets of the ENIGMA consortium. ASD was significantly associated with alterations of cortical thickness asymmetry in mostly medial frontal, orbitofrontal, cingulate and inferior temporal areas, and also with asymmetry of orbitofrontal surface area. These differences generally involved reduced asymmetry in individuals with ASD compared to controls. Furthermore, putamen volume asymmetry was significantly increased in ASD. The largest case-control effect size was Cohen's d = -0.13, for asymmetry of superior frontal cortical thickness. Most effects did not depend on age, sex, IQ, severity or medication use. Altered lateralized neurodevelopment may therefore be a feature of ASD, affecting widespread brain regions with diverse functions. Large-scale analysis was necessary to quantify subtle alterations of brain structural asymmetry in ASD.
conferenceObject Third Ventricle Enlargement in Bipolar Children and Unaffected Bipolar Offspring(2012) CAETANO, Sheila C.; KLEINMAN, Ana; TEIXEIRA, Ana Maria; DURAN, Fabio; OTADUY, Maria C. G.; LEITE, Claudia; STANLEY, Jeffrey A.; SOARES, Jair C.; BUSATTO, Geraldo F.; LAFER, Beny- Neurobiological support to the diagnosis of ADHD in stimulant-naive adults: pattern recognition analyses of MRI data(2017) CHAIM-AVANCINI, T. M.; DOSHI, J.; ZANETTI, M. V.; ERUS, G.; SILVA, M. A.; DURAN, F. L. S.; CAVALLET, M.; SERPA, M. H.; CAETANO, S. C.; LOUZA, M. R.; DAVATZIKOS, C.; BUSATTO, G. F.Objective: In adulthood, the diagnosis of attention-deficit/hyperactivity disorder (ADHD) has been subject of recent controversy. We searched for a neuroanatomical signature associated with ADHD spectrum symptoms in adults by applying, for the first time, machine learning-based pattern classification methods to structural MRI and diffusion tensor imaging (DTI) data obtained from stimulant-naive adults with childhood-onset ADHD and healthy controls (HC). Method: Sixty-seven ADHD patients and 66 HC underwent high-resolution T1-weighted and DTI acquisitions. A support vector machine (SVM) classifier with a non-linear kernel was applied on multimodal image features extracted on regions of interest placed across the whole brain. Results: The discrimination between a mixed-gender ADHD subgroup and individually matched HC (n = 58 each) yielded area-under-the-curve (AUC) and diagnostic accuracy (DA) values of up to 0.71% and 66% (P = 0.003) respectively. AUC and DA values increased to 0.74% and 74% (P = 0.0001) when analyses were restricted to males (52 ADHD vs. 44 HC). Conclusion: Introvert personality traits showed independent risk effects on suicidality regardless of diagnosis status. Among high risk individuals with suicidal thoughts, higher neuroticism tendency is further associated with increased risk of suicide attempt.
- Obsessive-compulsive symptom dimensions correlate to specific gray matter volumes in treatment-naive patients(2012) ALVARENGA, Pedro G.; ROSARIO, Maria C. do; BATISTUZZO, Marcelo C.; DINIZ, Juliana B.; SHAVITT, Roseli G.; DURAN, Fabio L. S.; DOUGHERTY, Darin D.; BRESSAN, Rodrigo A.; MIGUEL, Euripedes C.; HOEXTER, Marcelo Q.Background: Clinical and sociodemographic findings have supported that OCD is heterogeneous and composed of multiple potentially overlapping and stable symptom dimensions. Previous neuroimaging investigations have correlated different patterns of OCD dimension scores and gray matter (GM) volumes. Despite their relevant contribution, some methodological limitations, such as patient's previous medication intake, may have contributed to inconsistent findings. Method: Voxel-based morphometry was used to investigate correlations between regional GM volumes and symptom dimensions severity scores in a sample of 38 treatment-naive OCD patients. Several standardized instruments were applied, including an interview exclusively developed for assessing symptom dimensions severity (DY-BOCS). Results: Scores on the ""aggression"" dimension were positively correlated with GM volumes in lateral parietal cortex in both hemispheres and negatively correlated with bilateral insula, left putamen and left inferior OFC. Scores on the ""sexual/religious"" dimension were positively correlated with GM volumes within the right middle lateral OFC and right DLPFC and negatively correlated with bilateral ACC. Scores on the ""hoarding"" dimension were positively correlated with GM volumes in the left superior lateral OFC and negatively correlated in the right parahippocampal gyrus. No significant correlations between GM volumes and the ""contamination"" or ""symmetry"" dimensions were found. Conclusions: Building upon preexisting findings, our data with treatment-naive OCD patients have demonstrated distinct GM substrates implicated in both cognitive and emotion processing across different OCS dimensions.
