Parkinson’s disease is a disease that has no cure. Although it’s more commonly seen in older individuals, it can sometimes strike at a younger age as in the case of Michael J. Fox who developed the symptoms at age thirty. It’s a progressive neurological disease that involves degeneration of the nervous system leading to a tremor, rigidity, and movement problems. Not surprisingly, this disease can be associated with depression. Obviously, this is a condition that no one wants. What can you do to lower the risk of Parkinson’s disease? A new study shows that exposure to pesticides may be associated with this common neurological condition.

A Study

In a study published in the Archives of Neurology, researchers found a two times elevated risk of Parkinson’s disease in people who had been exposed to pesticides while on the job. One particular pesticide called 2,4-dichlorophenoxyacetic acid was particularly problematic. The researchers noted that exposure to any of eight different pesticides appeared to increase the risk of Parkinson’s disease – particularly 2,4 – dichlorophenoxyacetic acid.

What is 2,4 – dichlorophnoxyacetic acid?

2,4 – dichlorophenoxyacetic acid is a herbicide that’s used for weed control and is found in some lawn products such as Trillion and Tri-Kil. According to Wikipedia, over 1,500 herbicides contain 2,4 – dichlorophenoxyacetic acid as their active ingredient. This chemical was also used during the Vietnam War as a component of Agent Orange. In 2008, a report showed an association between this herbicide and heart disease as well as Parkinson’s disease – disturbing news for those who use lawn products.

Other Factors That Increase the Risk of Parkinson’s Disease

This neurological disease is more commonly seen in males, so being male or having a family history of the disease increases the risk. One study showed that head trauma, particularly head trauma requiring hospitalization, increases the risk by up to four times. High levels of iron and manganese have also been associated with a greater risk of Parkinson’s disease in some studies – possibly because they generate free radicals. Another study showed that people who have a high iron intake through diet are at an elevated risk of Parkinson’s disease.

Factors That Reduce the Risk of Parkinson’s Disease

Are there lifestyle factors that can lower the risk of Parkinson’s disease? Some studies have shown that coffee drinkers may have a lower risk. Researchers believe it’s the caffeine that’s the protective component and it isn’t clear whether caffeinated tea also reduces risk. Some studies also suggest that regular exercise and use of non-steroidal anti-inflammatory medications can lower the risk of Parkinson’s disease.

The Bottom Line

Parkinson’s disease is not a disease that’s completely preventable, but if you have a family history of the disease or are otherwise at high risk, it’s wise to reduce exposure to herbicides and pesticides – particularly ones containing 2,4 – dichlorophenoxyacetic acid.
