Introduction
Previous research has provided compelling support for the presence of olfactory dysfunction in patients with schizophrenia.1 Thus far, impairments across a wide variety of olfactory tasks have been well-documented, including reduced odor identification,2,3 odor detection threshold sensitivity,4 odor discrimination,4 odor memory,5 and odor hedonic judgments.6–8 Importantly, the nature of this impairment extends beyond the behavioral level as structural and physiological abnormalities in the underlying neurocircuitry of the olfactory system have been documented, ranging from reduced volume in the olfactory bulbs,9 posterior nasal cavity, and olfactory eloquent brain regions10,11 to abnormal olfactory event-related potentials and electro-olfactograms.
