Normal gray and white matter volume after weight restoration in adolescents with anorexia nervosa

Int J Eat Disord. 2013 Dec;46(8):841-8. doi: 10.1002/eat.22161. Epub 2013 Jul 31.

Abstract

Objective: The aim of this study was to determine whether treated, weight-stabilized adolescents with anorexia nervosa (AN) present brain volume differences in comparison with healthy controls.

Method: Thirty-five adolescents with weight-recovered AN and 17 healthy controls were assessed by means of psychopathology scales and magnetic resonance imaging. Axial three-dimensional T1-weighted images were obtained in a 1.5 Tesla scanner and analyzed using optimized voxel-based morphometry (VBM).

Results: There were no significant differences between controls and weight-stabilized AN patients with regard to global volumes of either gray or white brain matter, or in the regional VBM study. Differences were not significant between patients with psychopharmacological treatment and without, between those with amenorrhea and without, as well as between patients with restrictive versus purgative AN.

Discussion: The present findings reveal no global or regional gray or white matter abnormalities in this sample of adolescents following weight restoration.

Keywords: adolescents; anorexia nervosa; neuroimaging; statistical parametric mapping.
