Introduction
I am a researcher in (neuro)psychology. I am interested in the emergence of anxiety and depressive disorders or symptoms in children and adolescents. I study both the brain and various factors related to child anxiety or depression, from birth to adolescence, including: - Brain functioning and anatomy - Prematurity - Parenting - Intergenerational transmission - Child temperament, cognitive abilities, sex, age - Socioeconomic status

L’objet de cet article est de présenter une revue des divers facteurs de risques et des corrélats neuronaux associés au développement des troubles intériorisés, soit les troubles anxieux et dépressifs. Un accent est mis sur la contribution de l’exposition aux contaminants environnementaux dans le développement de troubles intériorisés, en particuli...

Background: Having a parent with an anxiety disorder increases the risk of anxiety symptoms and anxiety disorders during the lifespan. Moreover, childhood and adolescence anxiety disorders and symptoms have been linked to a range of brain structure abnormalities. However, to date, no study has investigated brain anatomy in adolescents at high risk...

Quality control (QC) of brain magnetic resonance images (MRI) is an important process requiring a significant amount of manual inspection. Major artifacts, such as severe subject motion, are easy to identify to naïve observers but lack automated identification tools. Clinical trials involving motion‐prone neonates typically pool data to obtain suff...
Article
Childhood adversity and anxiety have been associated with increased risk for internalizing disorders later in life and with a range of brain structural abnormalities. However, few studies have examined the link between harsh parenting practices and brain anatomy, outside of severe maltreatment or psychopathology. Moreover, to our knowledge, there h...

Objective: To evaluate how sociodemographic characteristics and various aspects of parent well-being, family functioning, parent-child relationship, and child characteristics are related to psychological functioning in children aged 9 to 12 years during the COVID-19 lockdown. Method: Participants included 144 children aged 9 to 12 years and thei...
Article
Exposure to mercury, lead and polychlorinated biphenyls (PCBs) have been associated with emotional dysregulation, but their neuronal correlates have yet to be examined. Inuit from Nunavik (Northern Quebec, Canada) face internalizing problems and are among the most exposed individuals to these environmental contaminants in the world. The aim of this...
Article
Full-text available
In adults, higher anxiety level related to COVID-19 has been associated with having a preexisting medical or mental health condition and poor sleep quality. However, no study yet has looked at these links in children. The present study’s main aim was to assess family changes associated with child and parent fears and concerns about COVID-19. We con...

IntroductionDeep learning neural networks are especially potent at dealing with structured data, such as images and volumes. Both modified LiviaNET and HyperDense-Net performed well at a prior competition segmenting 6-month-old infant magnetic resonance images, but neonatal cerebral tissue type identification is challenging given its uniquely inver...
Article
Dysfunctions in fronto-amygdala circuitry have been linked to anxiety. Questions remain regarding the impact of familial-risk and ongoing anxiety on such circuitry function, especially in youth. Using fMRI fear conditioning and extinction paradigms, we examined these relationships in 10-17 year-olds: 22 youth with an anxiety disorder, 22 healthy yo...

With increasing advances in the field of medical brain imaging, the known spectrum of white matter lesions has expanded, and we can now assess the presence of punctate white matter lesions (PWML). These focal small lesions are quite frequently detected in the preterm infant and in full-term infants with congenital heart malformations with, some stu...

Our open source quality control pipeline, DICOMetrics, attempted to classify 2D MRI images with major quality issues using data obtained from an example neonatal brain imaging study with 52 participants and 1040 DICOM images. The pipeline operated at per 2D DICOM file level and leveraged numerous existing no-reference image analyses metrics to quan...
Article
Background: Being born small for gestational age has been associated with neurodevelopmental disabilities and smaller gray matter volumes in childhood. However, it is not known if these changes persist in adults and whether SGA has any impact on attention memory and IQ. Aims: The goal of this study was to evaluate the association between birth w...
Conference Paper
Introduction: Large-scale magnetic resonance imaging (MRI) studies in newborns is difficult since the data is often hard to collect and aggregate. The Canadian Neonatal Brain Platform is a new initiative supported by Brain Canada to facilitate multi-center neonatal brain imaging studies and collect clinical neonatal brain MRI with shared common pro...
Conference Paper
Introduction: Being born Small for Gestational Age has been associated with neurodevelopmental disabilities and smaller gray matter volumes and cortical thickness in childhood. However, specific impact of being born small for gestational age on cortical gray matter anatomy, in correlation to comprehensive neurocognitive evaluation, has rarely been...
Conference Paper
Full-text available
Background and aims Being born Small for Gestational Age (SGA) has been associated with neurodevelopmental disabilities and smaller gray matter volumes and cortical thickness in childhood, as well as smaller surface areas in adults. However, gray matter volume has never been studied in adults. The goal of this study was to evaluate the association...

Full-text available
Significant left subclinical hemi-neglect or "hemi-unawareness" in juvenile and adult ADHD has been reported many times. However, this literature has never been thoroughly reviewed, and is generally ignored in neuropsychological accounts of ADHD. The purposes of the present report were (1) to introduce a systematic review of this literature and (2)...

We report 2 experiments designed to demonstrate that unilateral tachistoscopic stimulation would yield a response time (RT) advantage over bilateral stimulation in a simple experiment, whereas the opposite pattern would occur in a complex version of the same task, as predicted by the intrahemispheric resource limitation model of Banich and colleagu...
Article
Full-text available
Neurocognitive accounts of delusion have traditionally highlighted perceptual misrepresentation, as the primary trigger in addition to other cognitive deficits that maintain the delusion. Here, a general neurocognitive model of delusional disorder (DSM-IV) is proposed, not so much based on perceptual or cognitive deficits after right hemisphere dam...

Project
This project aims to examine psychological impacts associated with the COVID-19 pandemy. In particular, the impact on family functioning and children well-being. In the current context of pandemic, confinement and increased anxiety in adults, it seems important to identify factors on which we could act to reduce anxiety, depression and adjustment difficulties in the most vulnerable families.
Project
Identify risk factors for developing mental health disorders in children and adolescents, with a view to setting up early interventions before the disorder becomes chronic. The second goal is to improve our understanding of these disorders and risk factors. A third objective is to understand the cognitive, emotional and cerebral development of young people with and without a mental health disorder.
