Tremorogenic Parkinson's Disease

by Erik Steel

Overview

Tremorogenic means "causing tremors." The symptom most commonly associated with Parkinson's disease is tremor, or shaking in the limbs. Almost everyone who develops Parkinson's disease has a tremor, although it varies in intensity.
Location

Tremor and other symptoms of Parkinson's develop on one side of the body (one hand, for instance) and only later spread to the other side of the body. According to the Mayo Clinic, the side first affected will remain the most severely affected.

Features

Medline Plus reports that tremor is normally seen when limbs are resting or held out, and the tremor stops when the limbs are in motion.
Factors

Tremor may become worse when a person with Parkinson's is under stress, or when they are tired or excited, according to Medline Plus.
Pill Rolling

According to the Mayo Clinic and Medline Plus, a related symptom called pill rolling can occur. In this movement, the forefinger is rubbed across the thumb.
Effects

Tremor generally becomes worse over time and it might spread to other body parts, including the head (lips and tongue) and feet, according to Medline Plus.
