abstract = {The neurobiological mechanisms of structural brain
abnormalities in patients with anorexia nervosa (AN) remain
poorly understood. In particular, little is known about the
changes in and the recovery of gray matter (GM) volumes
after weight gain and the relation to hormonal normalization
in adolescent patients with AN.Nineteen female patients aged
12 to 17 years were assessed using magnetic resonance
imaging at the time of admission to the hospital (T1) and
after weight recovery (T2). Patients were compared with
typically developing girls matched for age and intelligence
quotient. Structural brain images were analyzed using a
voxel-based morphometric approach. Circulating levels of
cortisol and gonadotropins were assessed in blood
samples.Compared with controls, patients with AN showed
reduced GM in several brain regions along the cortical
midline, reaching from the occipital cortex to the medial
frontal areas. These GM reductions were mostly reversible at
T1. Patients showed a GM increase from T1 to T2 along the
cortical midline and in the occipital, temporal, parietal,
and frontal lobes. GM increases at T2 correlated inversely
with cortisol levels at T1 and positively with weight gain
at T2. The strongest associations between regional GM
increase and weight gain were found in the cerebellum. In
addition, increases in GM volumes at T2 in the thalamus,
hippocampus, and amygdala were associated with increases in
follicle-stimulating hormone.Our data suggest that brain
alterations in adolescents with acute AN are mostly
reversible at T1 and that GM recovery in specific brain
regions is associated with weight and hormonal
normalization.},
