Reduced Suprathreshold Odor Identification in Patients with Pseudotumor Cerebri: A Non-Randomized Prospective Study

Summary

Background:

Recent evidence suggests that olfaction is impaired in patients with pseudotumor cerebri (PTC).

Objectives

: To measure suprathreshold olfactory function by using the University of Pennsylvania Smell Identification Test (UPSIT), assessing its usefulness for routine clinical use.

Methods:

Forty PTC patients underwent USPIT olfactory testing.

Results:

Twenty-nine out of 40 (73%) PTC patients (36 women, 4 men; mean age 34 years) had reduced suprathreshold smell sensation according to UPSIT scores: 19 (47%) had mild microsmia, 9 (23%) had moderate microsmia, and one (3%) was classified as having severe microsmia. The mean UPSIT score of all patients was 32.4 (95% confidence interval 31.4–33.4). Multivariate regression analysis found that UPSIT scores were not related to disease activity, disease duration, initial intracranial pressure (ICP), or visual function.

Conclusions:

Many PTC patients have reduced suprathreshold olfactory dysfunction that can be discovered by UPSIT, a rapidly administered smell test, which is suitable for clinical office use.
