Information processing in adolescents with bipolar I disorder / Jane WHITNEY in Journal of Child Psychology and Psychiatry, 53-9 (September 2012)
[article]
Titre : Information processing in adolescents with bipolar I disorder Type de document : Texte imprimé et/ou numérique Auteurs : Jane WHITNEY, Auteur ; Jutta JOORMANN, Auteur ; Ian H. GOTLIB, Auteur ; Ryan G. KELLEY, Auteur ; Tenah ACQUAYE, Auteur ; Meghan HOWE, Auteur ; Kiki D. CHANG, Auteur ; Manpreet K. SINGH, Auteur Année de publication : 2012 Article en page(s) : p.937-45 Langues : Anglais (eng) Mots-clés : Adolescence bipolar disorder information-processing memory bias longitudinal Index. décimale : PER Périodiques Résumé : Background: Cognitive models of bipolar I disorder (BD) may aid in identification of children who are especially vulnerable to chronic mood dysregulation. Information-processing biases related to memory and attention likely play a role in the development and persistence of BD among adolescents; however, these biases have not been extensively studied in youth with BD. Methods: We administered the self-referent encoding task and the dot-probe task to adolescents with bipolar I disorder (BD, n = 35) and a demographically similar healthy comparison group (HC, n = 25) at baseline, and at a 1-year follow-up in a subset of this cohort (n = 22 per group). Results: At both baseline and 1-year follow-up, there were significant interactions of group (BD, HC) and valence of stimulus (positive, negative adjective) on endorsement and recall of self-referent adjectives. HC adolescents endorsed and recalled more positive self-referent adjectives at baseline and follow-up while adolescents with BD endorsed and recalled more negative self-referent adjectives at baseline but not follow-up. Over time, depression symptomatology was associated with impaired memory for positive self-referent adjectives. There were no group differences in attentional bias at either time points. Conclusions: Adolescents with BD exhibit bias away from endorsement and recall of positive adjectives, which remained stable over time and independent of mood state.

Titre : Neural correlates of emotion processing predict resilience in youth at familial risk for mood disorders Type de document : Texte imprimé et/ou numérique Auteurs : Akua F. NIMARKO, Auteur ; Amy S. GARRETT, Auteur ; Gabrielle A. CARLSON, Auteur ; Manpreet K. SINGH, Auteur Article en page(s) : p.1037-1052 Langues : Anglais (eng) Mots-clés : bipolar disorder emotion processing functional connectivity functional magnetic resonance imaging major depressive disorder youth Index. décimale : PER Périodiques Résumé : Aberrant face emotion processing has been demonstrated in youth with and at a familial risk for bipolar and major depressive disorders. However, the neurobiological factors related to emotion processing that underlie resilience from youth-onset mood disorders are not well understood. Functional magnetic resonance imaging data during an implicit emotion processing task were collected at baseline from a sample of 50 youth, ages 8–17, who were healthy but also familially at high risk for either bipolar disorder or major depressive disorder, and 24 healthy controls with no family history of psychopathology (HCL). Participants were reevaluated 3 years later and classified into three groups for analysis: high-risk youth who converted to a psychiatric diagnosis (CVT; N = 23), high-risk youth who were resilient from developing any psychopathology (RES; N = 27), and HCL youth (N = 24) who remained healthy at follow-up. For happy > calm faces, the CVT and RES groups had significantly lower activation in the left inferior parietal lobe (IPL), while the RES group had lower activation in the right supramarginal gyrus. For fear > calm faces, the RES group had lower activation in the right precuneus and inferior frontal gyrus (IFG) compared to the CVT group. Connectivity analyses revealed the RES group exhibited higher left IPL connectivity with visual cortical regions for happy > calm faces, and higher IFG connectivity with frontal, temporal, and limbic regions for fear > calm faces. These connectivities were correlated with improvements in prosocial behaviors and global functioning. Our findings suggest that differential activation and connectivity in the IPL, IFG, and precuneus in response to emotional stimuli may represent distinct resilience and risk markers for youth-onset mood disorders.
