PARKINSON’S DISEASE<br />

An overview<br />

INTRODUCTION<br />

Park<strong>in</strong>son‟s disease (PD) was first formally described <strong>in</strong> modern times <strong>in</strong> a<br />

famous monograph entitled “An essay on the shak<strong>in</strong>g palsy” published <strong>in</strong> 1817 by an<br />

English physician called James Park<strong>in</strong>son (Park<strong>in</strong>son 1817; Figure 1). In this report, the<br />

disease was <strong>in</strong>itially def<strong>in</strong>ed as shak<strong>in</strong>g palsy (paralysis agitans) and the syndromes<br />

observed were described as “<strong>in</strong>voluntary tremulous motion, with lessened muscular<br />

power, <strong>in</strong> parts not <strong>in</strong> action and even when supported; with a propensity to bend the<br />

trunk forward, and to pass from a walk<strong>in</strong>g to a runn<strong>in</strong>g pace: the senses and <strong>in</strong>tellects<br />

be<strong>in</strong>g un<strong>in</strong>jured”.<br />
