Medientyp: E-Artikel Titel: Structural hippocampal alterations, perceived stress, and coping deficiencies in patients with anorexia nervosa Beteiligte: Burkert, Nathalie T.; Koschutnig, Karl; Ebner, Franz; Freidl, Wolfgang Erschienen: Wiley, 2015 Erschienen in: International Journal of Eating Disorders Sprache: Englisch DOI: 10.1002/eat.22397 ISSN: 0276-3478; 1098-108X Schlagwörter: Psychiatry and Mental health Entstehung: Anmerkungen: Beschreibung: <jats:title>ABSTRACT</jats:title><jats:sec><jats:title>Objective</jats:title><jats:p>Anorexia nervosa (AN) is a severe mental illness that mainly affects young females. Studies have found a reduction of the hippocampus‐amygdala formation in people with AN, a brain region that is especially vulnerable to stress. In addition, patients with AN were found to perceive higher stress levels and to have more coping deficiencies than healthy controls. No prior study has considered a connection between stress, coping, and the hippocampal volume in AN. Therefore, the purpose of our study was to analyze the volume of hippocampal substructures, and its relation to stress and coping.</jats:p></jats:sec><jats:sec><jats:title>Method</jats:title><jats:p>We tested 21 females currently affected by AN and 21 age‐matched normal controls (NC). Demographic and behavioral data were assessed. A magnetic resonance (MR) scanner was used to collect data reflecting volume of cortical structures. We performed comparisons between groups and calculated correlations between the hippocampal volume and coping strategies or stress.</jats:p></jats:sec><jats:sec><jats:title>Results</jats:title><jats:p>The results showed a significant reduction of the hippocampal fimbria and a significant enlargement of the hippocampal fissure in patients with AN compared to the NC. In addition, patients with AN were found to report higher stress levels and to have more coping deficiencies than healthy controls. The hippocampal volume showed a trend‐level association with stress in patients with AN.</jats:p></jats:sec><jats:sec><jats:title>Discussion</jats:title><jats:p>In sum, our study provides the first‐available evidence that perceived stress in patients with AN could be related to hippocampal volume. Our results may contribute to a better understanding of the pathophysiology of AN and, therefore, help to improve the treatment. © 2015 Wiley Periodicals, Inc.
