Anxious/depressed symptoms are related to microstructural maturation of white matter in typically developing youths / Matthew D. ALBAUGH in Development and Psychopathology, 29-3 (August 2017)  

Public ISBD [article]  inDevelopment and Psychopathology > 29-3 (August 2017) . - p.751-758 Titre : Anxious/depressed symptoms are related to microstructural maturation of white matter in typically developing youths Type de document : Texte imprimé et/ou numérique Auteurs : Matthew D.

We investigated the degree to which anxious/depressed symptoms are tied to age-related microstructural changes in cerebral fiber pathways. The participants were part of the NIH MRI Study of Normal Brain Development. Child Behavior Checklist A/D scores and diffusion imaging were available for 175 youths (84 males, 91 females; 241 magnetic resonance imagings) at up to three visits. The participants ranged from 5.7 to 18.4 years of age at the time of the scan. Alignment of fractional anisotropy data was implemented using FSL/Tract-Based Spatial Statistics, and linear mixed model regression was carried out using SPSS. Child Behavior Checklist A/D was associated with the rate of microstructural development in several white matter pathways, including the bilateral anterior thalamic radiation, bilateral inferior longitudinal fasciculus, left superior longitudinal fasciculus, and right cingulum. Across these pathways, greater age-related fractional anisotropy increases were observed at lower levels of A/D. The results suggest that subclinical A/D symptoms are associated with the rate of microstructural development within several white matter pathways that have been implicated in affect regulation, as well as mood and anxiety psychopathology.

Association of cumulative prenatal adversity with infant subcortical structure volumes and child problem behavior and its moderation by a coexpression polygenic risk score of the serotonin system / Henriette ACOSTA in Development and Psychopathology, 36-3 (August 2024)

Yet, research on cumulative prenatal adversity, as well as its interaction with offspring genotype, on brain and behavioral development is scarce. With this study, we aimed to address this gap. In Finnish mother-infant dyads, we investigated the association of a cumulative prenatal adversity sum score (PRE-AS) with (a) child emotional and behavioral problems assessed with the Strengths and Difficulties Questionnaire at 4 and 5 years (N = 1568, 45.3% female), (b) infant amygdalar and hippocampal volumes (subsample N = 122), and (c) its moderation by a hippocampal-specific coexpression polygenic risk score based on the serotonin transporter (SLC6A4) gene. We found that higher PRE-AS was linked to greater child emotional and behavioral problems at both time points, with partly stronger associations in boys than in girls. Higher PRE-AS was associated with larger bilateral infant amygdalar volumes in girls compared to boys, while no associations were found for hippocampal volumes. Further, hyperactivity/inattention in 4-year-old girls was related to both genotype and PRE-AS, the latter partially mediated by right amygdalar volumes as preliminary evidence suggests. Our study is the first to demonstrate a dose-dependent sexually dimorphic relationship between cumulative prenatal adversity and infant amygdalar volumes.

A theme in these requirements is the need to preserve creative approaches and risk-taking within individual laboratories at the same time as common standards are provided for these laboratories to build on.

The neuroanatomy of the autistic phenotype / Cherine FAHIM in Research in Autism Spectrum Disorders, 6-2 (April-June 2012)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 6-2 (April-June 2012) . - p.898-906 Titre : The neuroanatomy of the autistic phenotype Type de document : Texte imprimé et/ou numérique Auteurs : Cherine FAHIM, Auteur ; Nagwa A. MEGUID, Auteur ; Neveen H. NASHAAT, Auteur ; Uicheul YOON, Auteur ; Adham MANCINI-MARIE, Auteur ; Alan C. EVANS, Auteur Année de publication : 2012 Article en page(s) : p.898-906 Langues : Anglais (eng) Mots-clés : Autism  Fragile X syndrome  Williams syndrome  Gray matter  White matter  Neuroimaging Index. décimale : PER Périodiques Résumé : The autism phenotype is associated with an excess of brain volume due in part to decreased pruning during development. Here we aimed at assessing brain volume early in development to further elucidate previous findings in autism and determine whether this pattern is restricted to idiopathic autism or shared within the autistic phenotype (fragile X syndrome [FXS]). We investigated brain volume in 37 participants, using the fully automated Civet pipeline anatomical magnetic resonance imaging. 3 groups with intellectual deficiency: autism (AUT); its most associated FXS; and its most opposite Williams syndrome (WS) were compared with each other and with normal controls (NC). We report increased total and regional gray and white matter brain volume in AUT and FXS relative to WS and NC. These findings are discussed in light of the possibilities leading for the enlarged brain volume in children with the AUT phenotype. We speculate that this excess suggests reduced regression of neuronal processes “pruning” in cortical and subcortical regions in AUT/FXS, which may be due to a mutation in specific genes involved in pruning and/or a lack of socio-emotional environmental experience during a critical developmental period.
