Abstract

Background: The re-emergent tremor of Parkinson's disease (PD) is generally recognized as a postural tremor.

Phenomenology shown: A PD patient with a re-emergent tremor occurring during a task (spiral drawing), which on the surface produced a tremor that resembled that of essential tremor (ET).

Educational value: Researchers and clinicians should be aware of features of this re-emergent tremor to help distinguish it from that of ET.

Keywords: Essential tremor; Parkinson’s disease; clinical; diagnosis; screening.
