Abstract

BackgroundIt is possible that psychopathological differences exist between the restricting and bulimic forms of anorexia nervosa. We investigated localized differences of brain blood flow of anorexia nervosa patients using SPECT image analysis with statistic parametric mapping SPM in an attempt to link brain blood flow patterns to neurophysiologic characteristics.

MethodsThe subjects enrolled in this study included the following three groups: pure restrictor anorexics AN-R, anorexic bulimics AN-BP, and healthy volunteers HV. All images were transformed into the standard anatomical space of the stereotactic brain atlas, then smoothed. After statistical analysis of each brain image, the relationships among images were evaluated.

ResultsSPM analysis of the SPECT images revealed that the blood flow of frontal area mainly containing bilateral anterior cingulate gyri ACC was significantly decreased in the AN-R group compared to the AN-BP and HV groups.

ConclusionsThese findings suggest that some localized functions ofthe ACCare possibly relevant to the psychopathological aspects of AN-R.
