Environmental Factors And Exposures
Exposure to pesticides and a history of head injury have each been linked with PD, but the risks are modest. Never having smoked cigarettes, and never drinking caffeinated beverages, are also associated with small increases in risk of developing PD.
Low concentrations of urate in the blood is associated with an increased risk of PD.
Different medical drugs have been implicated in cases of parkinsonism. Drug-induced parkinsonism is normally reversible by stopping the offending agent. Drugs include:
Treatment Options For Early Onset Parkinsons Disease
Parkinsons treatment aims to slow the diseases progression. Medication treatment options may include the following:
- Levodopa is a chemical thats converted to dopamine in the brain. People with early onset Parkinsons may experience more negative side effects, such as involuntary movements.
- MAO-B inhibitors can help reduce the breakdown of dopamine in the brain.
- Catechol-O-methyltransferase inhibitors can help extend Levodopas effects on the brain.
- Anticholinergics can help reduce tremors.
- Amantadine may be used to improve muscle control and relieve stiffness.
What Are The Management Options For Canadians Living With Parkinsonism
There is currently no cure for Parkinsons disease and most other parkinsonism cases. However, treatment options are available to help mitigate the symptoms and health impacts associated with these conditions. Most often the primary treatment is pharmacological, but it may also include other therapeutic options and, in the case of Parkinsons disease, surgical interventions. Studies have shown that specially tailored exercise programs, supervised by physiotherapists or other trained professionals, may help affected individuals maintain or improve their physical functionality and general well-being.Footnote 2 Footnote 3 Footnote 4 Footnote 5

Diagnosis And Management Of Parkinsons Disease
There are no diagnostic tests for Parkinsons. X-rays, scans and blood tests may be used to rule out other conditions. For this reason, getting a diagnosis of Parkinsons may take some time.
No two people with Parkinsons disease will have exactly the same symptoms or treatment. Your doctor or neurologist can help you decide which treatments to use.
People can manage their Parkinsons disease symptoms through:
- seeing a Doctor who specialises in Parkinsons
- multidisciplinary therapy provided for example, by nurses, allied health professionals and counsellors
- deep brain stimulation surgery .
Highlights From The Canadian Chronic Disease Surveillance System
Parkinsonism, including Parkinsons disease, can have significant impacts for those affected, their caregivers, and society. With a growing and aging population, it is estimated that the number of Canadians living with parkinsonism will double between 2011 and 2031 and that the incidence will increase by 50%.Footnote 1
The Public Health Agency of Canada , in collaboration with all Canadian provinces and territories, conducts national surveillance of parkinsonism to support the planning and evaluation of related policies, programs, and services. This fact sheet presents an overview of the data on diagnosed parkinsonism, including Parkinsons disease, from the Canadian Chronic Disease Surveillance System .

Diagnosis Of Parkinsons Disease
A number of disorders can cause symptoms similar to those of Parkinson’s disease. People with Parkinson’s-like symptoms that result from other causes are sometimes said to have parkinsonism. While these disorders initially may be misdiagnosed as Parkinson’s, certain medical tests, as well as response to drug treatment, may help to distinguish them from Parkinson’s. Since many other diseases have similar features but require different treatments, it is important to make an exact diagnosis as soon as possible.
There are currently no blood or laboratory tests to diagnose nongenetic cases of Parkinson’s disease. Diagnosis is based on a person’s medical history and a neurological examination. Improvement after initiating medication is another important hallmark of Parkinson’s disease.
Parkinson’s Disease Is Difficult To Diagnose
Parkinson’s is a challenge to diagnose since there is no definitive test for it. Blood tests and scans are usually run just to rule out other causes of the symptoms.
If a GP suspects a patient could have Parkinson’s, they may refer them to a neurologist who can make a diagnosis based on medical history, a review of the signs and symptoms and a physical examination. It can help to keep a diary of symptoms leading up to the appointment.
Diagnosing Parkinson’s disease in some people can be a long process.

Tips For Caring For Someone With Parkinsons Disease
Caring for a loved one with early onset Parkinsons can be difficult. If youre a caregiver for someone with this condition, its important that you remember your own emotional and physical health.
Not only are you dealing with a difficult diagnosis, youre also managing an increased number of responsibilities. Burnout is common in caregivers, so make sure youre checking in with your own needs.
The Michael J. Fox Foundation Center for Parkinsons Research recommends these tips for caregivers:
Deep Brain Stimulation Parkinsons Disease & Age Considerations
Parkinson disease is a chronic progressive condition that most commonly affects the elderly. Currently, about 1 million Americans have PD, but studies suggest that the prevalence of the disease will double by 2030. Research has shown that deep brain stimulation is an effective treatment for reducing motor disability and improving quality of life for patients with advanced PD who have severe levodopa-induced motor fluctuations and dyskinesia. However, DBSlike any other surgical procedureis associated with inherent risks and potential complications, including hemorrhage, wound infection, and pneumonia.
It has become increasingly important to examine the effect of increasing age on DBS candidacy and surgical complications, says Shivanand P. Lad, MD, PhD. The common perception among some clinicians is that patients older than 65 with PD should not undergo DBS because of the potential risks for postoperative complications. Few studies, however, have specifically assessed the effect of advancing chronologic age on postoperative complications in older patient groups.

What Is The Treatment For Parkinson’s Disease
There is currently no treatment to cure Parkinson’s disease. Several therapies are available to delay the onset of motor symptoms and to ameliorate motor symptoms. All of these therapies are designed to increase the amount of dopamine in the brain either by replacing dopamine, mimicking dopamine, or prolonging the effect of dopamine by inhibiting its breakdown. Studies have shown that early therapy in the non-motor stage can delay the onset of motor symptoms, thereby extending quality of life.
The most effective therapy for Parkinson’s disease is levodopa , which is converted to dopamine in the brain. However, because long-term treatment with levodopa can lead to unpleasant side effects , its use is often delayed until motor impairment is more severe. Levodopa is frequently prescribed together with carbidopa , which prevents levodopa from being broken down before it reaches the brain. Co-treatment with carbidopa allows for a lower levodopa dose, thereby reducing side effects.
In earlier stages of Parkinson’s disease, substances that mimic the action of dopamine , and substances that reduce the breakdown of dopamine inhibitors) can be very efficacious in relieving motor symptoms. Unpleasant side effects of these preparations are quite common, including swelling caused by fluid accumulation in body tissues, drowsiness, constipation, dizziness, hallucinations, and nausea.
Incidence Of Parkinsons Disease
Its estimated that approximately four people per 1,000 in Australia have Parkinsons disease, with the incidence increasing to one in 100 over the age of 60. In Australia, there are approximately 80,000 people living with Parkinsons disease, with one in five of these people being diagnosed before the age of 50. In Victoria, more than 2,225 people are newly diagnosed with Parkinsons every year.

Parkinsons Disease Or Simply Signs Of Aging How To Know The Difference
Parkinsons disease is a fairly common brain disorder among seniors. It causes shaking and stiffness and affects balance and coordination. In some sufferers, it also causes dementia. On average, those with Parkinsons are diagnosed around age 60, although the risk increases with age. Every year, about 60,000 people are diagnosed with the condition in the United States. Theres a good chance that many more actually suffer from the disease, however. According to the National Institutes of Health, this is because its easy to confuse early symptoms of the disease with things that happen normally during the aging process.
Knowing how to spot the early symptoms of Parkinsons can help. If you notice any of these signs in your loved one, see a doctor. According to the National Parkinson Foundation, signs to watch for include:
Progression of the Disease
While an early diagnosis can greatly improve quality of life, the disease is progressive. The symptoms can continue to worsen as your senior ages. This may take an emotional toll on both you and your loved one. Youll both be asked to continually adapt to the changes in health, abilities, and independence. Those with Parkinsons slowly lose their mobility, ability to provide self-care and, in some cases, mental capacity.
The Last Year Of Life In Parkinson’s Disease
The study also examined nearly 45,000 hospitalizations in people with terminal Parkinson’s, meaning their end-of-life period.
Of those with terminal PD, the most common reasons for being in the hospital were:
- Heart disease
- Lung disease that was not from an infection
Less common causes for hospitalization were problems related to the stomach or intestines, muscles, nervous system, or endocrine system .
It is not surprising that infection was the most common hospitalization before death, as people with Parkinson’s are vulnerable to developing a number of infections as a result of their disease. For example, bladder dysfunction in Parkinson’s increases a person’s risk of developing urinary tract infections, which can become life-threatening if not detected and treated promptly.
In addition, research suggests that aspiration pneumonia is 3.8 times more common in people with Parkinson’s as compared to the general population. It has also been consistently reported to be the main cause of death in people with Parkinson’s.
Aspiration pneumonia results from underlying swallowing difficulties, which leads to stomach contents being inhaled into the lungs. Immobilization and rigidity, which can impair phlegm removal, also contribute to the development of pneumonia in people with Parkinson’s.

Is There A Way To Slow The Progress Of Parkinson’s
Parkinson’s disease is a progressive disorder, which means its symptoms worsen slowly over time. There is no cure for Parkinson’s disease yet and no known way to slow its progress.
But there are treatments and medications that can control or reduce the symptoms and help people live productive lives. Some research suggests that regular exercise may slow the progress of Parkinson’s. Physical activity can also alleviate stiffness and other symptoms.
There are other things a person can do to feel better after a diagnosis of Parkinson’s, such as joining social support groups and learning as much as possible about the disease. It’s also important to make the home safer and less cluttered, since a person with Parkinson’s is more likely to fall.
While it’s not always easy, neurologists say a positive mindset can also help.
Young Onset Parkinsons : An Introduction
Although the average age to develop Parkinsons is around 60, young onset Parkinsons occurs in 5-10% of people diagnosed. 20% are under the age of 50. Some challenges in Parkinsons are universal, regardless of age, but there are a number of issues specific to younger people.
Generally, Parkinsons proceeds more slowly in younger people. While no two people are the same, someone whose onset age is 40 can expect to work for another 15-20 years on average. For someone with an onset age of 60, the average figure would be half that. These figures are based on the kinds of treatment available today. Future treatment will be even more effective in prolonging the productive life of people with Parkinsons.
Larry Gifford hosts a panel discussion on Living Well with Young Onset Parkinsons in May of 2020.
The following characteristics tend to be present in young onset Parkinsons:
- Young onset Parkinsons is less likely to lead to dementia and balance problems
- It is more likely to include focal dystonia, which is cramping or abnormal posturing of one part of the body.
- Younger people are more sensitive to the benefits of Parkinson medications, but they tend to experience the dyskinetic side effects of levodopa sooner than older people.
- They also tend to experience dose-related fluctuations at an earlier stage of the disease, including wearing off* and the on-off effect. See Parkinson Canada Information Sheet, Parkinsons Medications: What you need to know!

Who Is Affected By Parkinsons Disease
Parkinsons disease affects both men and women. Statistically, however, men have a slightly higher chance of developing the disease. The risk of developing Parkinsons disease also increases with age, with the average age of onset being 65 years old. Five to ten per cent of people develop the condition before the age of 40 years old. When symptoms appear in people aged 21-40, this is known as young-onset Parkinsons disease. Juvenile Parkinsons disease is the term used when symptoms appear before the age of 18 years old, although this is extremely rare.
To-date, no one knows exactly why people get Parkinsons disease, but viral infection or environmental toxins may play a role. People with a parent, sibling or child with Parkinsons disease, are twice as likely to get it as people in the general population.
Symptoms Of Parkinson’s Disease
You can attribute the symptoms of Parkinson’s to a deficiency of a chemical in your brain called dopamine. The four classic motor symptoms of Parkinson’s include:
Shaking and tremors while you are resting is typically the first sign of Parkinson’s disease, but about one-third of patients won’t experience those symptoms. These symptoms tend to be worsened by emotional and physical stress. Sleep or moving can help reduce these issues.
Parkinson’s disease is both chronic and progressive with symptoms generally getting worse as time goes on. As it progresses, other disabilities can develop, including:
- Difficulty talking and swallowing
- A sudden inability to move,
Some sufferers also have symptoms that don’t affect their motor skills, including:
- Mental health issues such as anxiety, depression and memory loss
- Loss of smell
- Trouble sleeping, including thrashing and other sudden movements
- Change in blood pressure

Caring For Your Health With Parkinson’s Disease
In addition to caring for your Parkinson’s health, it is also important to care for your overall health. This means visiting your primary care physician periodically for preventive care like the annual flu shot and cancer screeningsfor example, a mammogram for breast cancer screening and a colonoscopy for colon cancer screening.
A primary care physician can also evaluate for risk factors related to heart attacks and strokes, and provide counseling on exercise, smoking, alcohol use, depression, or other mental health concerns. Regular visits to your primary care physician or neurologist will also allow them to catch bacterial infections like urinary tract infections before they get serious.
Seven Signs Of Early Onset Parkinsons
There are a series of symptoms that can alert us to the early onset of Parkinsons disease. There are more signs, but were going to focus on these seven:
- Sleep disorders. The most common disorders are insomnia , restless legs syndrome, and REM sleep behavior disorder.
- Depression. This is one of the first symptoms to appear and is in fact considered an early indicator of the disease.
- Other mood changes. In addition to depressive symptoms, anxiety and apathy are very common. These symptoms can negatively influence the desire to seek help and resolution.
- Cognitive changes. Many people with early onset Parkinsons usually find it difficult to do more than one thing at once. Poor task execution, slower thinking speed, attention and concentration problems, memory problems, and dementia are all symptoms of early onset Parkinsons.
- Tremors. Although they usually start in the hands, they start in the jaw or on the feet in other patients. The most characteristic thing about these tremors is that they occur at rest.
- Bradykinesia. This is a gradual loss of spontaneous movement. General movement simply slows down. This is one of the most disabling and frustrating symptoms for those affected.
- Fatigue. With early onset Parkinsons, the patient feels tired all the time without having exerted themselves at all.

Causes Of Parkinson’s Disease
Parkinson’s disease is caused by a loss of nerve cells in part of the brain called the substantia nigra. This leads to a reduction in a chemical called dopamine in the brain.
Dopamine plays a vital role in regulating the movement of the body. A reduction in dopamine is responsible for many of the symptoms of Parkinson’s disease.
Exactly what causes the loss of nerve cells is unclear. Most experts think that a combination of genetic and environmental factors is responsible.
What Are The Symptoms Of Parkinsons Disease
The symptoms of Parkinsons disease develop gradually, as levels of dopamine fall. Early Parkinsons disease symptoms usually affect one side of the body. The main symptoms of Parkinsons disease include:
- Tremors: uncontrollable shaking, the symptom most associated with the disease, often beginning in the hands.
- Rigidity: stiffness or tensing of the muscles.
- Bradykinesia: slowness of movement, and loss of spontaneous movement.
- Postural instability: lack of balance and coordination which may lead to falling.
People with Parkinsons disease may also experience other problems, including tiredness, depression, sleep problems, cognitive impairment and difficulties with handwriting. They can also find their speech and facial expression change and some people have difficulties eating and swallowing.
