What Happens to Your Body When You Have Parkinson’s Disease?

Parkinson’s disease (PD) is a progressive neurological disorder that affects millions of people around the world. But what happens to your body when you have Parkinson’s disease? Understanding the physical and neurological changes caused by PD can help individuals and their loved ones better manage the journey ahead.

​What Happens to Your Body When You Have Parkinson’s Disease?
When someone develops Parkinson’s disease, it primarily affects a region of the brain called the substantia nigra, which plays a key role in controlling movement. In this area, nerve cells produce a chemical called dopamine, which helps transmit signals between parts of the brain that coordinate smooth, purposeful motion. In Parkinson’s, these cells gradually die off, causing dopamine levels to drop significantly.
​
The result? A cascade of motor and non-motor symptoms that impact the body in many ways:
Motor Symptoms

• Tremors: One of the most recognizable symptoms, often starting in the hands or fingers while at rest.
• Bradykinesia: This refers to slowness of movement, making everyday tasks—like buttoning a shirt—much more difficult.
• Rigidity: Muscles become stiff and inflexible, which can limit range of motion and cause discomfort.
• Postural Instability: Balance and coordination decline over time, increasing the risk of falls.
• Shuffling Walk: Many people with PD develop a stooped posture and a short-stepped gait.

While Parkinson’s is a chronic condition with no known cure, there are many ways to manage its symptoms and maintain quality of life. Medical treatment, physical therapy, a healthy lifestyle, and—most importantly--community support all play essential roles.

The Parkinson’s Association of Southwest Florida (PASWFL) has been a lifeline for individuals and families living with PD in the region for over twenty-five years. PASWFL provides free programs and services designed to improve quality of life, educate, enrich, and empower those affected by Parkinson’s and related neurological conditions.

Each week, they offer more than 25 free programs and support groups for individuals with PD and their care partners. From movement classes to expert-led seminars, these resources are available at no cost to members. Becoming a member is easy, and there's no fee required.
