An amygdala-centered hyper-connectivity signature of threatening face processing predicts anxiety in youths with autism spectrum conditions / Y. C. CHEN in Autism Research, 14-11 (November 2021)  

Public ISBD [article]  inAutism Research > 14-11 (November 2021) . - p.2287-2299 Titre : An amygdala-centered hyper-connectivity signature of threatening face processing predicts anxiety in youths with autism spectrum conditions Type de document : Texte imprimé et/ou numérique Auteurs : Y. C. CHEN, Auteur ; C. CHEN, Auteur ; R. M. MARTÍNEZ, Auteur ; Y. T. FAN, Auteur ; C. C. LIU, Auteur ; C. Y. CHEN, Auteur ; Y. CHENG, Auteur Article en page(s) : p.2287-2299 Langues : Anglais (eng) Mots-clés : Adolescent  Amygdala/diagnostic imaging  Anxiety/complications  Autism Spectrum Disorder/complications/diagnostic imaging  Autistic Disorder  Case-Control Studies  Facial Recognition  Humans  Magnetic Resonance Imaging  amygdala  autism spectrum condition (ASC)  explicit  implicit  threat Index. décimale : PER Périodiques Résumé : Anxiety is exceedingly prevalent among individuals with an autism spectrum condition (ASC). While recent literature postulates anxiety as a mechanism encompassing an underlying amygdala-related elevated baseline level of arousal even to nonthreatening cues, whether this same mechanism contributes to anxiety in those with an ASC and supports the transdiagnostic nature of anxiety remains elusive. In this case-control study of 51 youths (26 ASC), we assessed autism and anxiety via the Autism-Spectrum Quotient and the State-Trait Anxiety Inventory, respectively. Hemodynamic responses, including amygdala reactivity, to explicit and implicit (backwardly masked) perception of threatening faces were acquired using functional Magnetic Resonance Imaging (fMRI). For explicit fear, ASC individuals showed significantly greater negative correlations between the amygdala and the attentional deployment-parietal network. For implicit fear, ASC individuals showed significantly stronger correlations of the amygdala with the prefrontal networks, temporal pole, and hippocampus. Additionally, an fMRI-based neurologic signature for anxiety in ASCs was identified via the LibSVM machine learning model using amygdala-centered functional connectivity during the emotional processing of explicit and implicit stimuli. Hypervigilance to implicit threat in ASCs comorbid with anxiety might exacerbate explicit threat reactivity; hence the use of attentional avoidance patterns to restrict affective hyperarousal for explicitly perceived socioemotional stimuli. Consequently, developing an attention-independent behavioral/neural marker identifying anxiety in ASCs is highly warranted. LAY SUMMARY: This study identifies a dissociation of amygdala reactivity dependent on explicit and implicit threat processing. Implicit anxiety in individuals with an autism spectrum condition (ASC) could outweigh explicitly induced threat. When explicitly perceiving socioemotional stimuli, ASC individuals with anxiety might use attentional avoidance patterns to restrict affective hyperarousal.

Do parenting behaviors modify the way sensation seeking influences antisocial behaviors? / M. OKUDA in Journal of Child Psychology and Psychiatry, 60-2 (February 2019)

METHODS: Data were obtained from the Boricua Youth Study, a longitudinal study of 2,491 Puerto Rican youth living in the South Bronx, New York, and the metropolitan area of San Juan, Puerto Rico. First, we examined the prospective relationship between sensation seeking and antisocial behaviors across 3 yearly waves and whether this relationship varied by sociodemographic factors. Second, we examined the moderating role of parenting behaviors-including parental monitoring, warmth, and coercive discipline-on the prospective relationship between sensation seeking and antisocial behaviors. RESULTS: Sensation seeking was a strong predictor of antisocial behaviors for youth across two different sociocultural contexts. High parental monitoring buffered the association between sensation seeking and antisocial behaviors, protecting individuals with this trait. Low parental warmth was associated with high levels of antisocial behaviors, regardless of the sensation seeking level. Among those with high parental warmth, sensation seeking predicted antisocial behaviors, but the levels of antisocial behaviors were never as high as those of youth with low parental warmth. CONCLUSIONS: Study findings underscore the relevance of person-family context interactions in the development of antisocial behaviors. Future interventions should focus on the interplay between individual vulnerabilities and family context to prevent the unhealthy expression of a trait that is present in many individuals.

Among those with FXS exhibiting IAAS, individuals with FXS receiving drug treatment of IAAS were older, more predominantly male, have more significant intellectual disability, more like to have comorbid autism, hyperarousal, and social impairments. The most commonly utilized medications for IAAS in FXS are antipsychotic medications, specifically aripiprazole and risperidone (37% and 27%, respectively). The majority of subjects (63%) experienced no side effects noted from the use of their psychopharmacologic medications.

Sex differences in global and local connectivity of adolescent posttraumatic stress disorder symptoms / X. CAO in Journal of Child Psychology and Psychiatry, 60-2 (February 2019)

METHODS: Based on a recently burgeoning theory of psychopathology networks, this study conducted sex comparisons of global and local connectivity of PTSD symptoms in a sample of 868 disaster-exposed adolescents (57.0% girls; a mean age of 13.4 +/- 0.8 years) with significant PTSD symptomatology evaluated by the UCLA PTSD Reaction Index for DSM-IV. RESULTS: The results revealed that global connectivity was stronger in girls' network than in boys', and individual symptoms' connectivity and its rankings differed by sex. Intrusive recollections, flashbacks, avoiding activities/people, and detachment were the most strongly connected symptoms in girls, whereas flashbacks, physiological cue reactivity, diminished interest, and foreshortened future were the most strongly connected symptoms in boys. Several symptoms were identified as featuring large connectivity differences across sex. CONCLUSIONS: These findings provide novel insights into sex differential risk and features of youth's PTSD symptomatology. Sex differences reflected in the co-occurrence of PTSD symptoms may merit more consideration in research and clinical practice.
