Utilization behavior and concomitant motor neglect by bilateral frontal lobe damage.
We reported on a patient who had bilateral mesial frontal lesions, presumably of a primary cerebral malignant lymphoma. The patient presented with a combination of unusual behavioral disorders of the upper extremities, which has not yet been documented in the literature: bilateral utilization and imitation behaviors and motor neglect of the left arm. Utilization behavior was closely associated with bilateral manual grasping behavior and was caused by the bifrontal lesions. Damage to the right supplementary motor area resulted most likely in concomitant motor neglect of the left hand. Discussion includes differentiation from other related behavioral disorders.
