Pesticide Exposure Raises Risk Of Parkinson’s
Exposure to pesticides even at relatively low levels may increase an individuals risk of developing Parkinsons disease by 70%, according to a study of more than 140,000 people. Researchers say that the findings strengthen the hypothesis that such chemicals somehow promote the development of the disease.
In recent years, experts have identified genetic mutations that apparently predispose people to develop Parkinsons. But some mystery remains because not everyone with the mutations will get the devastating neurological disorder, which is characterised by rigid and slow movement or other problems with body coordination. Likewise, Parkinsons can develop in individuals with no known genetic predisposition.
As a result, many scientists maintain that environmental factors ultimately trigger the development of Parkinsons disease.
The idea that pesticides may be to blame has now received a boost from the first large-scale, prospective study to examine this possible link. Alberto Ascherio of the Harvard School of Public Health in Boston, Massachusetts, US, and colleagues looked at data from roughly 143,000 people involved in a cancer and diet study, of whom 413 were diagnosed with Parkinsons disease in the 1990s.
Receptor Agonists And Antagonists
Investigations into anatoxin-a, also known as “Very Fast Death Factor”, began in 1961 following the deaths of cows that drank from a lake containing an algal bloom in Saskatchewan, Canada. It is a cyanotoxin produced by at least four different genera of cyanobacteria, and has been reported in North America, Europe, Africa, Asia, and New Zealand.
Toxic effects from anatoxin-a progress very rapidly because it acts directly on the nerve cells . The progressive symptoms of anatoxin-a exposure are loss of coordination, twitching, convulsions and rapid death by respiratory paralysis. The nerve tissues which communicate with muscles contain a receptor called the nicotinic acetylcholine receptor. Stimulation of these receptors causes a muscular contraction. The anatoxin-a molecule is shaped so it fits this receptor, and in this way it mimics the natural neurotransmitter normally used by the receptor, acetylcholine. Once it has triggered a contraction, anatoxin-a does not allow the neurons to return to their resting state, because it is not degraded by cholinesterase which normally performs this function. As a result, the muscle cells contract permanently, the communication between the brain and the muscles is disrupted and breathing stops.

Some Are Calling Parkinsons A Man
Researchers are rapidly coming to the viewpoint that a large number of Parkinsons cases are tied to toxins. These researchers are even reaching conclusions that environment outranks genetics as a cause of Parkinsons.
One 2020 book discussed an exhaustive study of 17,000 twin brothers to pinpoint the effects that environment could play. The researchers found that people exposed to certain environmental factors were more than twice as likely to develop Parkinsons.
Strong Links Found But Still Uncertain
More evidence is needed to fully understand the role of manganese in causing parkinsonism and other metals that may contribute to these symptoms. But what the Washington University School of Medicine is certain of is that increased exposure to manganese is not good news.
Dr. Racette pointed out the studys limitations: for example, the study was based on a survey of the workers rather than direct measurement of manganese exposure. But, he added: This study suggests that we need more stringent workplace monitoring of manganese exposure, greater use of protective equipment and monitoring, and systematic assessment of workers to prevent this disabling disease.

Causes And Risk Factors Of Asbestosis
Asbestosis is caused only by exposure to asbestos. Inhaling asbestos causes microscopic fibers to become lodged within lung tissue, leading to damage and scarring.
The damage caused by asbestos is due to inflammation of the tissue in the lungs. Inflammation occurs when your body senses a foreign invader and sends macrophages, a type of white blood cell, and other immune cells to stimulate and boost the immune system.
The scar tissue that forms as a result of the inflammation can occur around the lungs air sacs, or alveoli, making it more difficult for your body to receive oxygen. Asbestosis can also affect fibroblast cells, which produce the extracellular matrix and collagen responsible for the integrity of your lungs.
Workers in the construction, railroad, automotive and shipbuilding industries are more likely to be at risk for asbestosis.
Another group of at-risk workers includes drywall removers, firefighters, demolition workers and others who assisted at the World Trade Center after the 9/11 attacks. These workers were exposed to asbestos used in the construction of the north tower.
Asbestos exposure can develop into asbestosis based on the following factors:
- Amount and concentration of asbestos
- Size, shape and chemical makeup of the asbestos
- Length of time an individual was exposed to asbestos
- Health factors such as smoking or a history of lung disease
- Genetic factors or specific mutations in DNA that increase risk of disease

Can Asbestos Exposure Cause Lung Cancer
Although exposure to asbestos alone can lead to lung cancer, the risk increases dramatically in smokers of cigarettes or other forms of tobacco.
- In nonsmokers who have been exposed to asbestos, the risk of lung cancer is five times that of unexposed workers.
- Smokers who are exposed to asbestos have a 50 to 84 times greater risk of lung cancer, according to the Agency for Toxic Substances Disease Registry.
Lung cancer in asbestos-exposed and unexposed individuals is similar in both the type of cancer and its signs and symptoms. The link between cigarette smoking, asbestos, and cancer of the lung itself does not apply to cancer of the lining of the lung . Diagnosis and treatment of lung cancer is a complex topic and a pulmonary specialist should be involved in the workup of a suspected lung cancer.
Asbestos is the only known risk factor for malignant mesothelioma, a cancer that affects the tissue lining the lung or abdomen . Malignant mesothelioma is not associated with cigarette smoking but is strongly linked with the degree of asbestos exposure. However, 20% to 40% of patients with malignant mesothelioma have no prior asbestos exposure. In malignant mesothelioma, there is a very long duration between exposure and the onset of disease, usually greater than 30 years.
Advancing Age And Parkinsons Disease
Age is perhaps the biggest risk factor for the onset of Parkinsons disease. The average age at which people will develop this movement disorder is 60. This is not usually something that affects younger people. The brain ages as people get older.
Even without external factors, cells in the substantia nigra can die on their own as an individual ages, causing symptoms to develop as the person gets older.

Education And Smoking Assessment
Education and smoking were included to control for possible confounding. Information was taken from questionnaires in 1961 and 1963 for twins born 18861925 and in 1973 for twins born 19261947. Educational level was categorized as having completed compulsory school only or any higher education. In this study population, compulsory school was 6, 7 or 8 years of education depending on birth year. Smoking status was categorized as never, current, or past smoker at the time of the questionnaire.

What Is The Treatment For Asbestosis
Patients with asbestosis, like others with chronic lung disease, are at a higher risk of serious infection, low oxygen levels in the blood, and heart failure. These patients also may not recover as quickly from viral and bacterial infections. In addition, they may be at increased risk for certain fungal and unusual infections that take advantage of diseased or scarred lung tissue. The medical management of these patients should focus special attention on preventing and rapidly treating these infections. Flu and pneumococcal vaccinations are a part of routine care for these patients. There is, however, no treatment or cure for asbestosis. In particular, steroid and immune-based therapies have not been shown to benefit these patients.
Other key elements in treating patients with asbestosis are smoking cessation, early detection of worsening disease or cancer, and avoidance of further exposure to asbestos. Supplemental oxygen during exercise or at rest may be provided to improve daily function.
Michael J Fox Foundation And Parkinsons Disease
The Parkinsons Alliance, led by;Michael J Fox Foundation for Parkinsons Research, initiated a two-year $4.4 million research project to fund research through grant money. One grant funded;Neonatal Pesticide Exposure and Parkinsons Disease by Mona Thiruchelvamat at the University of Rochester.
Thiruchelvamats project proposed determining if permanent neurotoxicity arose from Paraquat and maneb exposure to see if humans had an enhanced vulnerability after use. Her agricultural health study hypothesized that exposure to the herbicide and fungicide could cause permanent changes to the brain at specific times.
She found through her studies on test mammals that exposure to pesticides can produce permanent and progressive lesions of the nigrostriatal dopamine system and enhanced adult susceptibility to these pesticides, suggesting the developmental exposure to neural toxicants may be involved in the induction of neurodegenerative disorders or alter the normal aging process.

Reasons Parkinson’s Disease Can Occur
When a loved one is living with Parkinsons, its natural to wonder what caused the disease to take root. Although most cases of Parkison’s have an unknown cause, a very small percent of cases can be hereditary . Some studies have linked long-term exposure to pesticides, including one called paraquat, with an increased likelihood of the development of Alzheimers and Parkinsons disease.;
The pesticide was first introduced in the United States in the 1950s and is still used commonly by licensed users today. If you think that your loved one who has been diagnosed with Parkinsons may have been exposed to paraquat, its important that you work with a lawyer to learn whether you may be eligible for compensation. Caring for a loved one with Parkinsons can be costly and time-consuming, especially in the later stages when your loved one requires around-the-clock care. Financial compensation can make it easier to provide your loved one with the care they deserve throughout the progression of the disease.;
Were here to help you decide what to do next after you find out that paraquat exposure may be responsible for the development of Parkinsons disease in your loved one. Reach out to us today for a free case review.
What Is The Prognosis
The disease gets progressively worse, with people becoming severely disabled within three to five years of onset. Affected individuals are predisposed to serious complications such as pneumonia, choking, head injury, and fractures. The most common cause of death is pneumonia. With good attention to medical and nutritional needs, it is possible for individuals with PSP to live a decade or more after the first symptoms of the disease appear.

Common Symptoms Of Parkinsons Disease
Here are some of the early signs and symptoms of Parkinsons disease that you need to be on the lookout for in deciding to see a healthcare professional who can provide medical advice.
- Rigid muscles
- Lack of ability to write
- Slowed movement
- Low blood pressure
If you notice these, or other symptoms involving the nervous system, it is time to see a doctor. If you experience a sudden drop in the bodys ability to execute any of these tasks or control movements, it is a sign that something is wrong. Doctors may be able to give medications or other treatments that could improve symptoms.
What Causes Parkinsons Disease
Developing Parkinsons disease is not something that often happens on its own. Of course, there are genetic factors that could play a part in this neurological disorder. However, it is a combination of genetic and environmental factors that could lead to this disease.
In some cases, we have seen recent lawsuits that allege that exposure to certain chemicals has caused Parkinsons disease. Here, we will focus on how people could develop Parkinsons. That could give you an idea of whether you may have a possible lawsuit.

Environmental Factors In Parkinsons Disease
Here are environmental factors that may play a role in the development of Parkinsons disease:
Although environmental exposure to these and other toxins is of continued research interest, its hard to determine if any one substance is a culprit. Most often, individual cases of Parkinsons disease result from a complex interplay between genetics and environmental and other factors.
Targeting Parkinsons-Linked Protein Could Neutralize 2 of the Diseases Causes
Researchers report they have discovered how two problem proteins known to cause Parkinsons disease are chemically linked, suggesting that someday, both could be neutralized by a single drug designed to target the link.
