Abstract
Because olfactory dysfunction is a feature of neurodegenerative diseases, the authors hypothesized that it would be present in essential tremor. Thirty-seven cases and control subjects underwent the University of Pennsylvania Smell Identification Test. Mean score was lower in cases than in control subjects (29.0 +/- 6.1 vs 31.9 +/- 4.6, p = 0.02) and was not correlated with tremor severity or duration.
