Olfactory function, assessed by the University of Pennsylvania Smell Identification Test, was normal in essential tremor (ET) patients and significantly reduced in patients with Parkinson's disease (PD). This finding further supports a lack of association between ET and PD.
We analyzed the results of the Sickness Impact Profile, a self-reporting measure of sickness-related dysfunction in 753 essential tremor (ET) patients, 87 controls from the general population, and 145 patients with Parkinson's disease (PD). Compared with the general population, ET patients had significantly greater dysfunction in all but one category. Communication, Work, Emotional Behavior, Home Management, and Recreation and Pastimes were particularly impaired in ET. The PD patients had significantly higher dysfunction in all categories as compared with ET patients. We conclude that significant disability can occur in ET and, compared with PD, ET tends to be less severe but causes relatively greater psychosocial dysfunction.
