Does Parkinson’s disease affect more than just the brain?

When most people think of Parkinson’s disease (PD), they associate it with tremors and difficulty with movement, all of which stem from the brain. But the reality is more complex. 
Does Parkinson’s disease affect more than just the brain?
​The answer is yes — Parkinson’s is a systemic condition that impacts multiple systems throughout the body, not just the nervous system. Understanding its far-reaching effects can help individuals and families better manage the disease and seek support early on.

 Beyond the Brain: The Widespread Impact of Parkinson’s Disease

Parkinson’s disease is a neurodegenerative disorder primarily caused by the loss of dopamine-producing cells in a part of the brain called the substantia nigra. While the brain is the central site of the disease’s origin, its symptoms ripple through many other organs and systems, affecting a person’s total well-being.

The Digestive System One of the earliest non-motor symptoms of Parkinson’s is constipation. This happens because PD can slow down the muscles of the gut, leading to sluggish digestion. Swallowing problems may also emerge in later stages, which can lead to malnutrition or aspiration.
​
The Cardiovascular System Parkinson’s often affects the autonomic nervous system, which controls involuntary functions like heart rate and blood pressure. As a result, individuals may experience orthostatic hypotension, a sudden drop in blood pressure upon standing, leading to dizziness or fainting.

The Respiratory System Over time, Parkinson’s can weaken the muscles involved in breathing, leading to shallow breaths or even sleep apnea. These changes can be subtle but are crucial to monitor as they can affect oxygen intake and sleep quality.

The Muscular and Skeletal Systems Muscle rigidity and joint stiffness are hallmark symptoms of PD. These physical changes can impact posture, balance, and overall mobility. Over time, they can lead to muscle pain, fatigue, and a higher risk of falls.
​
The Urinary and Reproductive Systems People with Parkinson’s frequently report urinary urgency, frequency, or incontinence. These symptoms are linked to disruptions in the communication between the brain and bladder. Men may also experience changes in sexual function.

Whole-Body Care Through PASWFLGiven that Parkinson’s affects more than just the brain, whole-body care becomes essential. That’s where the Parkinson’s Association of Southwest Florida (PASWFL) comes in. For over 25 years, PASWFL has provided free, life-enhancing programs to individuals and families touched by PD in the region.

Each week, PASWFL offers more than 25 free programs and support groups to address both the physical and emotional aspects of Parkinson’s. Their programs include:

• Therapeutic exercise
• Balance and movement classes
• Speech therapy
• Support groups for care partners
• Educational events on managing all aspects of PD

Membership is completely free, and the organization is open to anyone affected by Parkinson’s disease.
