How Does Someone Get Parkinson’s Disease?

​It’s a question that crosses many minds the moment they hear the word “Parkinson’s”—but the truth may surprise you. While Parkinson’s Disease (PD) is the second most common neurodegenerative disorder in the world, there’s still no single known cause. If you or a loved one has recently been diagnosed, or if you’re searching for answers after noticing troubling symptoms, understanding the risk factors and scientific insights can help you take the first step toward managing PD with knowledge and hope.

Understanding What Causes Parkinson’s Disease
Parkinson’s Disease develops when cells in a specific part of the brain—called the substantia nigra—begin to die off or stop functioning properly. These cells produce dopamine, a neurotransmitter that plays a key role in movement, coordination, and mood. As dopamine levels drop, individuals may experience tremors, stiffness, balance issues, and more.
While we don’t yet know exactly what causes these cells to malfunction, research has identified several possible contributors:

Age & Gender factors in Parkinsons

​1. Genetics
Only about 10–15% of Parkinson’s cases are considered hereditary. Scientists have identified several gene mutations linked to PD, but having a mutation doesn’t guarantee someone will develop the disease. It only increases the risk.
2. Environmental Triggers
Prolonged exposure to pesticides, herbicides, and certain industrial chemicals may contribute to the development of Parkinson’s. Rural living and well-water use have also been correlated in some studies.
3. Age & Gender
PD most commonly appears after the age of 60, although early-onset cases do occur. Men are about 1.5 times more likely to develop Parkinson’s than women.
4. Head Trauma
Studies show that a history of serious head injuries may increase the risk of developing PD later in life.
Even with these risk factors, the cause is often a complex interplay of genetics and environmental factors. In many cases, there is no clear “why.”

Why Support Matters
A diagnosis of any form of Parkinson’s can feel overwhelming. But with the right support and resources, individuals can maintain independence, quality of life, and emotional well-being.
