In a study conducted by a team with Parkinson's Institute in California, United States of 519 Parkinson's patients and 511 healthy people, the researchers interviewed them about employment history and the experience of toxic exposure, including pesticides and liquid solvent.

Indeed those who work in the field of agriculture, education, health personnel or a welder not directly related to Parkinson's. However, the researchers found 8.5 percent of Parkinson's patients are often exposed to pesticides, compared with 5.3 percent who did not get Parkinson's.

"This research provides evidence of a casual relationship between exposure to pesticides and Parkinson's. What to know is the pesticide has a broad scope, not only fertilizer but also the chemicals," said Dr.Caroline M. Tanner, researcher.

In this research experts specifically identify the 8 types of pesticides have the highest toxicity based on laboratory tests. Three components, both organic (dichlorophenoxyacetic acid), herbicides (paraquat), and insecticide (permethrin), it increases the risk of Parkinson's disease. According to laboratory tests, the three components of the effect on dopamine.

Remaining free radicals metabolism and substances toxic to the nervous bersifar such as iron, herbicides, pesticides, can cause degeneration of neurons (cells introductory impulses in the nervous system) and damage to brain cells in substansia nigra. Consequently levels of dopamine in the brain decreases.

Low levels of dopamine, can cause a disruption in the brain that regulate movement can be arranged (volunteers) and the movement can not be regulated (involunteer).

The main symptoms of Parkinson's disease, is tremors (shaking), rigidity (stiffness of muscle movement, especially on the neck, arms, legs visible by halting the movement), akinesia / bradikinesia (slow motion, decreased eye blink, muscle less moving away, the sound decreases and monotonous, slow swallowing reflex, and saliva dripping out) and postural reflex that causes disturbed patients often fall.
