A re-examination of the rate of vocational dysfunction among patients with anosmia and mild to moderate closed head injury
Date of Original Version
This study sought to verify two earlier reports that up to 93% of patients with closed head injury (CHI) and anosmia are vocationally dysfunctional due to executive impairments associated with orbitofrontal damage. Participants were 11 men and 4 women identified from a pool of 60 potential subjects referred for evaluation of trauma-related chemosensory dysfunction at the University of Pennsylvania Smell and Taste Center from 1988 to 1994. These 15 subjects met four criteria: (i) willingness to complete a brief semi-structured interview concerning their pre- and post-CHI work history; (ii) age <60 years; (iii) evidence of mild to moderate CHI; and (iv) scores on the University of Pennsylvania Smell Identification Test indicative of anosmia or severe microsmia and non-malingering. In contrast to the earlier reports, only 7% of the subjects were vocationally dysfunctional. This study calls into question previous reports suggesting that anosmia is a reliable predictor of post-CHI vocational outcome. Copyright © 2001 National Academy of Neuropsychology.
