    • 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. ...

    • Cerebral structural and functional changes in adolescent females with anorexia nervosa 

      Myrvang, Anna Dahl (Doctoral thesis; Doktorgradsavhandling, 2022-05-25)
      Cerebral structural changes are associated with acute AN. Volume reduction is found in several regions, but it is unclear if this is a global phenomenon and how other morphological measures are affected. Cortical thickness (CTh) and surface area (CSA) are morphometrics that are less studied and develop with different trajectories in adolescence, when AN normally debuts. Alterations in the brains ...

    • Effects of cognitive-behavioral and psychodynamic-interpersonal treatments for eating disorders: a meta-analytic inquiry into the role of patient characteristics and change in eating disorder-specific and general psychopathology in remission 

      Moberg, Leif Tore; Solvang, Birgitte; Sæle, Rannveig Grøm; Myrvang, Anna Dahl (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-06-26)
      Background - Cognitive behavior therapy (CBT) and psychodynamic-interpersonal therapies (PIT) are two widely used and conceptually different outpatient treatments for eating disorders (EDs). To better understand how these treatments works, for whom, and under what circumstances, there is a need for knowledge about how outcomes are affected by diagnosis, comorbidity, changes in psychopathology, and ...

    • 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 ...
