VIDEO: What is Parkinson’s
THE MICHAEL J. FOX FOUNDATION GUIDE: Navigating Parkinson’s
It is important to note that not everyone with Parkinson’s will experience the same symptoms, and the order in which symptoms appear and the way symptoms progress also varies from person to person.
Additionally, non-motor symptoms such as sleep disturbance, constipation and loss of sense of smell can pre-date the motor symptoms, such as a tremor, slowness of movement or rigidity, by up to a decade.
Parkinson’s results from the loss of cells in various parts of the brain, including a region called the substantia nigra. When dopamine production is depleted, the motor system nerves are unable to control movement and coordination. The dopamine producing cells are lost over a period of years and the motor type symptoms such as tremor, rigidity etc. will start to appear.
The experience of living with Parkinson’s over the course of a lifetime is unique to each person. As symptoms and progression vary from person to person, neither you nor your doctor can predict which symptoms you will get, when you will get them or how severe they will be. Even though broad paths of similarity are observed among individuals with PD as the disease progresses, there is no guarantee you will experience what you see in others.
Australian Parkinson’s Statistics
Parkinson’s disease is poorly understood. The majority of the population understand it to be ‘just the shakes’. The reality is much different.
- Parkinson’s is the second most common neurological disease in Australia after dementia.
- The disease affects an estimated 10 million individuals worldwide – 200,000 in Australia.
- 38 Aussies are diagnosed with the disease every day.
- 20% of sufferers are under 50 years old and 10% are diagnosed before the age of 40.
- The number of people with Parkinson’s has increased by 17% in the last six years with costs to the community increasing by over 48%.
- For comparison purposes, the prevalence of Parkinson’s is greater than prostate, bowel, and many other forms of cancer and the total number of Parkinson’s sufferers is 4 times the number of people suffering from MS.

Is Parkinson’s Genetic?
In most cases, the cause of Parkinson’s disease is unknown. The Michael J. Fox Foundation for Parkinson’s Research states that better understanding of the complex genetic, environmental, aging and other factors that lead to Parkinson’s would be game-changing in our pursuit of preventive and therapeutic treatment options.
For most people, the cause of Parkinson’s is unknown or “idiopathic”. Researchers believe that Parkinson’s is caused by a combination of factors. If a continuum existed, with genetic causes at one end and environmental causes at the other, people with Parkinson’s would fall at many different places. Some cases may be due more to genetics, and others more influenced by environmental factors. We know aging plays a role, too. Scientists are working hard to understand the triggers and the cascade of cellular changes that lead to Parkinson’s. Knowing more about the cause could help researchers develop treatments to stop or even prevent the disease. Read more here.
Other Risk Factors of Parkinson’s
Because the causes of Parkinson’s disease are unknown, there is no scientifically validated preventive course to reduce the risk of its onset. The single biggest risk factor for Parkinson’s disease is advancing age. Men have a somewhat higher risk than women.
That being said, a number of studies have highlighted factors that are associated with either greater or lesser risk of Parkinson’s disease. For example, smoking and caffeine consumption have been associated with lower rates of Parkinson’s disease, while head injury and pesticide exposure have been associated with higher risk. While such studies do not definitively link these factors with Parkinson’s disease one way or another, they highlight areas where further research may guide us to risk-prevention or treatment strategies.

Parkinson's Symptoms
Symptoms of Parkinson’s disease vary from person to person and change over time and include motor and non-motor symptoms.
Parkinson’s Treatments
Current medications or surgery options can help to manage Parkinson’s symptoms, but we don’t yet have any treatments that can cure, slow, stop or reverse the progression.
Living with Parkinson’s
Living with Parkinson’s does require re-adjustment as the disease slowly progresses. We share some valuable information to help you live a better life.
Sharing Your Diagnosis
A Parkinson’s diagnosis affects everyone. Learn more about some commonly raised questions such as, what effect will it have on my relationship, how do I tell my children etc.
Young Onset Parkinson’s
It’s not just an old person’s disease. 20% of people diagnosed with Parkinson’s are under the age of 50. Learn more about Young Onset Parkinson’s.
