Document Summary

Parkinson"s disease is a movement disorder of middle and old age that affects 1-2% of the elderly population. It is about 2. 5 times more prevalent in males than in females. The initial symptoms of parkinson"s disease are mild perhaps no more than a slight stiffness or tremor of the finger but inevitably increase in severity with advancing years. The most common symptoms of full-blown disorder are a tremor that is pronounced during inactivity but not during voluntary movement or sleep, muscular rigidity, difficulty initiating movement, slowness of movement, and a masklike face. Pain and depression often develop before the motor symptoms become severe. Although dopamine is normally major neurotransmitter released by the most neurons of the substantia nigra, there is little dopamine in the substantia nigra and striatum of long-term parkinson"s patients. Most of the cells of the nervous system are of two different types: neurons and glial cells.
