Abstract

Body dysmorphic disorder (BDD) is a condition characterized by an intense preoccupation with an imagined or slight defect in physical appearance. Although there is a general consensus that psychosocial factors play a major role in the development of BDD, there is some evidence suggesting that an organic somatosensorial disturbance may also exist in this condition. Several psychiatric and neurological disorders, including the interparietal syndrome, Gertsman's syndrome, inferoparietal syndrome, phantom limb syndrome, genital retraction syndrome, panencephalitis, cerebrovascular syndromes, and pharyngeal streptococcia affecting the basal ganglia, can present with somatosensorial disturbances similar to BDD. The cerebral pathology in all these disorders appears to be localized in the parietal-occipital region, indicating that cerebral involvement may also be associated with BDD. An interdependence exists between cerebral regions through integrated neural networks that enable efficient processing of information. Disturbances in these association pathways can lead to an imbalance in the extensive cerebral loops. Therefore, it is possible that a defect in information-processing may play a role in the pathogenesis of BDD.
