Olfactory Test Accuracy in Distinguishing Tremor-Dominant Parkinson’s Disease from Essential Tremor: A Systematic Review and Meta-Analysis

2026-07-31

Abstract excerpt

<h4>Background: </h4> Hyposmia is a common nonmotor feature of Parkinson’s disease (PD) and is typically absent or mild in essential tremor (ET). Olfactory tests are low-cost, noninvasive tools that may improve diagnostic accuracy in tremor-dominant PD (TD-PD). <h4>Methods:</h4> PubMed/MEDLINE, Embase, and Cochrane Library were systematically searched through January 2026. Studies evaluating olfactory tests in TD-...
