Childhood maltreatment is associated with altered frontolimbic neurobiological activity during wakefulness in adulthood / Salvatore P. INSANA in Development and Psychopathology, 28-2 (May 2016)  

Public ISBD [article]  inDevelopment and Psychopathology > 28-2 (May 2016) . - p.551-564 Titre : Childhood maltreatment is associated with altered frontolimbic neurobiological activity during wakefulness in adulthood Type de document : Texte imprimé et/ou numérique Auteurs : Salvatore P. INSANA, Auteur ; Layla BANIHASHEMI, Auteur ; Ryan J. HERRINGA, Auteur ; David J. KOLKO, Auteur ; Anne GERMAIN, Auteur Article en page(s) : p.551-564 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Childhood maltreatment can disturb brain development and subsequently lead to adverse socioemotional and mental health problems across the life span. The long-term association between childhood maltreatment and resting–wake brain activity during adulthood is unknown and was examined in the current study. Forty-one medically stable and medication-free military veterans (M = 29.31 ± 6.01 years, 78% male) completed a battery of clinical assessments and had [18F]-fluorodeoxyglucose positron emission tomography neuroimaging scans during quiet wakefulness. After statistically adjusting for later-life trauma and mental health problems, childhood maltreatment was negatively associated with brain activity within a priori defined regions that included the left orbital frontal cortex and left hippocampus. Childhood maltreatment was significantly associated with increased and decreased brain activity within six additional whole-brain clusters that included the frontal, parietal–temporal, cerebellar, limbic, and midbrain regions. Childhood maltreatment is associated with altered neural activity in adulthood within regions that are involved in executive functioning and cognitive control, socioemotional processes, autonomic functions, and sleep/wake regulation. This study provides support for taking a life span developmental approach to understanding the effects of early-life maltreatment on later-life neurobiology, socioemotional functioning, and mental health.

Childhood maltreatment moderates the effect of combat exposure on cingulum structural integrity / Layla BANIHASHEMI in Development and Psychopathology, 29-5 (December 2017)  

Public ISBD [article]  inDevelopment and Psychopathology > 29-5 (December 2017) . - p.1735-1747 Titre : Childhood maltreatment moderates the effect of combat exposure on cingulum structural integrity Type de document : Texte imprimé et/ou numérique Auteurs : Layla BANIHASHEMI, Auteur ; Meredith L. WALLACE, Auteur ; Lei K. SHEU, Auteur ; Michael C. LEE, Auteur ; Peter J. GIANAROS, Auteur ; Robert P. MACKENZIE, Auteur ; Salvatore P. INSANA, Auteur ; Anne GERMAIN, Auteur ; Ryan J. HERRINGA, Auteur Article en page(s) : p.1735-1747 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Limbic white matter pathways link emotion, cognition, and behavior and are potentially malleable to the influences of traumatic events throughout development. However, the impact of interactions between childhood and later life trauma on limbic white matter pathways has yet to be examined. Here, we examined whether childhood maltreatment moderated the effect of combat exposure on diffusion tensor imaging measures within a sample of military veterans (N = 28). We examined five limbic tracts of interest: two components of the cingulum (cingulum, cingulate gyrus, and cingulum hippocampus [CGH]), the uncinate fasciculus, the fornix/stria terminalis, and the anterior limb of the internal capsule. Using effect sizes, clinically meaningful moderator effects were found only within the CGH. Greater combat exposure was associated with decreased CGH fractional anisotropy (overall structural integrity) and increased CGH radial diffusivity (perpendicular water diffusivity) among individuals with more severe childhood maltreatment. Our findings provide preliminary evidence of the moderating effect of childhood maltreatment on the relationship between combat exposure and CGH structural integrity. These differences in CGH structural integrity could have maladaptive implications for emotion and memory, as well as provide a potential mechanism by which childhood maltreatment induces vulnerability to later life trauma exposure.

Neurobehavioral correlates of impaired emotion recognition in pediatric PTSD / Sara A. HEYN in Development and Psychopathology, 34-3 (August 2022)  

Public ISBD [article]  inDevelopment and Psychopathology > 34-3 (August 2022) . - p.946-956 Titre : Neurobehavioral correlates of impaired emotion recognition in pediatric PTSD Type de document : Texte imprimé et/ou numérique Auteurs : Sara A. HEYN, Auteur ; Collin SCHMIT, Auteur ; Taylor J. KEDING, Auteur ; Richard WOLF, Auteur ; Ryan J. HERRINGA, Auteur Article en page(s) : p.946-956 Langues : Anglais (eng) Mots-clés : adolescent  emotion  functional neuroimaging  posttraumatic stress disorders Index. décimale : PER Périodiques Résumé : Despite broad evidence suggesting that adversity-exposed youth experience an impaired ability to recognize emotion in others, the underlying biological mechanisms remains elusive. This study uses a multimethod approach to target the neurological substrates of this phenomenon in a well-phenotyped sample of youth meeting diagnostic criteria for posttraumatic stress disorder (PTSD). Twenty-one PTSD-afflicted youth and 23 typically developing (TD) controls completed clinical interview schedules, an emotion recognition task with eye-tracking, and an implicit emotion processing task during functional magnetic resonance imaging )fMRI). PTSD was associated with decreased accuracy in identification of angry, disgust, and neutral faces as compared to TD youth. Of note, these impairments occurred despite the normal deployment of visual attention in youth with PTSD relative to TD youth. Correlation with a related fMRI task revealed a group by accuracy interaction for amygdala “hippocampus functional connectivity (FC) for angry expressions, where TD youth showed a positive relationship between anger accuracy and amygdala “hippocampus FC; this relationship was reversed in youth with PTSD. These findings are a novel characterization of impaired threat recognition within a well-phenotyped population of severe pediatric PTSD. Further, the differential amygdala “hippocampus FC identified in youth with PTSD may imply aberrant efficiency of emotional contextualization circuits.
