Parkinson's disease: researchers discover that workplace stress is a trigger

While medical research continues to advance for Parkinson's, the second most common neurodegenerative disease of the nervous system, the causes remain mysterious. An American study reveals a new one: stress at work.

Parkinson's disease is a neurological disease that affects a large number of patients. In France, in 2015, the number of cases treated was estimated at 160,000. If we know that this disease particularly affects the elderly and starts on average between 65 and 75 years, it is difficult to establish the other risk factors. Among the main ones identified are genetic factors and environmental factors. A study of 2015, Public Health France also revealed that farmers and residents have 10% additional risk of contracting the disease, especially because of pesticides.

In recent years other potential risk factors have been updated by researchers such as hepatitis C, according to a study conducted in Taiwan and published in the magazine Neurology.

Work stress: a new potential factor?

A recent American research published by the newspaper Movement Disorder just revealed a new potential factor: stress at work.

This study, which covers 2,544,748 Swedes born between 1920 and 1950, was conducted over 21 years, during which 21,544 new cases of the disease were identified. This study suggests that high-responsibility jobs are a risk factor, unlike jobs with fewer jobs.

According to the study, the risk of Parkinson's disease is thus increased when it is associated with people with high job requirements, especially those with a higher level of education, while it is lower among those with low levels of education. school.

If Parkinson's research continues to advance, including the first stem cell treatment at the University of Tokyo, it is very important to determine the causes of this disease. It is they that also help to prevent and better guide researchers for the development of new therapies.
