• Altered functional connectivity in adolescent anorexia nervosa is related to age and cortical thickness 

      Myrvang, Anna Dahl; Vangberg, Torgil R.; Linnman, Clas; Stedal, Kristin; Rø, Øyvind; Endestad, Tor; Rosenvinge, Jan H.; Aslaksen, Per M. (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-10-06)
      Introduction - Functional networks develop throughout adolescence when anorexia nervosa (AN) normally debuts. In AN, cerebral structural alterations are found in most brain regions and may be related to the observed functional brain changes. Few studies have investigated the functional networks of the brain in adolescent AN patients.. The aim of this explorative study was to investigate multiple ...
    • Cerebral cortical thickness and surface area in adolescent anorexia nervosa: Separate and joint analyses with a permutation-based nonparametric method 

      Myrvang, Anna Dahl; Vangberg, Torgil Riise; Stedal, Kristin; Rø, Øyvind; Endestad, Tor; Rosenvinge, Jan H; Aslaksen, Per M (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-12-17)
      <i>Objective</i> - Reduction in cerebral volume is often found in underweight patients with anorexia nervosa (AN), but few studies have investigated other morphological measures. Cortical thickness (CTh) and surface area (CSA), often used to produce the measure of cortical volume, are developmentally distinct measures that may be differentially affected in AN, particularly in the developing brain. ...
    • Childhood trauma and outcome trajectories in patients with longstanding eating disorders across 17 years 

      Eielsen, Hanna Kristine Punsvik; Ulvenes, Pål Gunnar; Hoffart, Asle; Rø, Øyvind; Rosenvinge, Jan Harald; Vrabel, KariAnne (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-10-27)
      Background: A large proportion of patients with eating disorders (ED) report experiences of childhood trauma. Latent trajectory analysis in ED samples reveals the complexities in course and outcome and can explore the long-term impact of adverse experiences in childhood.<p> <p>Method: A total of 84 patients with longstanding ED were included. ED symptoms were assessed by the Eating Disorder ...
    • Co-occurrence of avoidant personality disorder and child sexual abuse predicts poor outcome in longstanding eating disorders 

      Rosenvinge, Jan H.; Vrabel, KariAnne R.; Hoffart, Asle; Rø, Øyvind; Martinsen, Egil W. (Journal article; Tidsskriftartikkel; Peer reviewed, 2009-12-16)
      Few consistent predictive factors for eating disorder have been identified across studies. In the current five year prospective study, the objective was to examine whether (1) personality disorder and child sexual abuse predict the course of severity of eating disorder symptoms after inpatient treatment and (2) how the predictors interact. A total of 74 patients with long standing eating disorder ...
    • Hippocampal Subfields in Adolescent Anorexia Nervosa 

      Myrvang, Anna Dahl; Vangberg, Torgil Riise; Stedal, Kristin; Rø, Øyvind; Endestad, Tor; Rosenvinge, Jan H; Aslaksen, Per M (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-10-25)
      Patients with anorexia nervosa (AN) exhibit volume reduction in cerebral gray matter (GM), and several studies report reduced hippocampus volume. The hippocampal subfields (HS) are functionally and structurally distinct, and appear to respond differently to neuropathology. The aim of this study was to investigate HS volumes in adolescent females with restrictive AN compared to a healthy age-matched ...
    • Reciprocal relationships between personality disorders and eating disorders in a prospective 17-year follow-up study 

      Eielsen, Hanna Kristine Punsvik; Vrabel, KariAnne; Hoffart, Asle; Rø, Øyvind; Rosenvinge, Jan H (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-10-10)
      <p><b>Objective</b> This study aimed to report the presence of categorical and dimensional personality disorders (PD) in adults with longstanding eating disorders (ED) over a period of 17 years and to investigate whether changes in PD predict changes in ED symptoms or vice versa. <p><b>Methods</b> In total, 62 of the 80 living patients (78% response rate) with anorexia nervosa (<i>n</i> ...
    • Stressful life events and resilience in individuals with and without a history of eating disorders: a latent class analysis 

      Lie, Selma; Wisting, Line Norøm; Stedal, Kristin; Rø, Øyvind; Friborg, Oddgeir (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-10-16)
      Background - Eating disorders (EDs) are associated with a range of stressful life events, but few have investigated protective factors that may affect these associations. The current study used mixture modelling to describe typologies in life stress exposure and availability of protective resources in individuals with and without eating disorders (EDs).<p> <p>Methods - A case – control sample ...
