Parkinson's is a condition that has been known about since ancient times. It is referred to in the ancient Indian medical system of Ayurveda under the name Kampavata. In Western medical literature it was described by the physician Galen as "shaking palsy" in AD 175. However it was not until 1817 that a detailed medical essay was published on the subject by London doctor James Parkinson. (http://www.parkinsons.org/parkinsons-history.html)
Generally, in Parkinson's disease, brain cells called neurons, which produce a substance called dopamine -- a chemical that helps the nervous system control muscle activity -- begin to deteriorate. The exact reason for this is not known. When the neurons are destroyed, dopamine is not produced at the normal rate, and an abnormally low supply of dopamine causes Parkinson's symptoms to appear.
