Comparative StudyAssessment of anosmia after traumatic brain injury: performance characteristics of the University of Pennsylvania Smell Identification Test.
To examine the performance characteristics of two forms of the University of Pennsylvania Smell Identification Test (UPSIT) in a sample of persons with traumatic brain injury (TBI). ⋯ These findings support past investigations indicating that anosmia, and unawareness of olfactory dysfunction, are common in persons with TBI and related to injury severity. The use of the 3-item screening measure as a gross indicator was supported, although caution is advised, because nearly 20% of patients performing perfectly on the 3-item screen scored in the anosmic range on the full UPSIT.
