Differences Between Essential Tremor Developing Parkinson-s Disease and Essential Tremor

Abstract

Objective: Essential tremor (ET) is the most prevalent extrapyramidal disorder and some ET patients may later develop Parkinson-s disease (PD). However, up to date, precise association was not determined. To understand the relationship between ET and PD, we investigated differences between patients with ET and ET developing PD (ETPD) in terms of demographic and clinical characteristics.
