Abstract

Objective: To investigate quantitative positron emission tomography (PET) findings, particularly from orbitofrontal cortex. in patients with posttraumatic anosmia. Setting: Neuropsychology outpatient clinic and university brain imaging center. Subjects: Eleven patients with head injury resulting insevere anosmia and 11 controls matched for age. All 11 head-injured patients had their head injuries at least 2 years before involvement in the studyMeasures: Regional cerebral glucose metabolism was measured with PET. Results: Quantitative evaluation of PET findings fur anosmic patients as a group showed orbitofrontal hypometabolism compared with controls. Decreased activity was also noted in mesial temporal lobe. Activity in subcortical whitematter was essentially identical between groups. Conclusions: Findings strongly suggest that posttraumatic anosmia is closely associated with hypometabolism in the orbitofrontal cortex and the medial prefrontal cortex. The results also underscore the importance of posttraumatic anosmia as a clinical sign of orbitofrontal damage, as has been shown previously with neuroSPECT (single photon emission computed tomography).
