What Happens to the Body During Parkinson’s Disease?

​Parkinson’s disease (PD) is more than just tremors and stiffness. It’s a progressive neurological condition that affects how the brain communicates with the rest of the body. Many people ask, “What happens to the body during Parkinson’s disease?” Understanding the changes that occur can empower individuals and families to seek appropriate care, treatment, and support early on.

​What Happens to the Body During Parkinson’s Disease?
Parkinson’s disease occurs when nerve cells in the brain, particularly in an area called the substantia nigra, begin to deteriorate or die. These cells are responsible for producing dopamine, a chemical that helps control movement. As dopamine levels drop, the body loses its ability to regulate smooth, controlled motions. Over time, this leads to both motor and non-motor symptoms.

Motor Symptoms

The most well-known effects of Parkinson’s disease on the body are related to movement. These include:

• Tremors – Involuntary shaking, often starting in the hands or fingers.
• Bradykinesia – Slowness of movement, which can make everyday tasks difficult.
• Muscle rigidity – Stiffness in the limbs and trunk that can limit range of motion.
• Postural instability – Impaired balance and coordination, increasing the risk of falls.
• Freezing – Sudden, brief inability to move, often experienced when starting to walk.

Non-Motor SymptomsWhat happens to the body during Parkinson’s disease goes beyond physical movement. Non-motor symptoms are just as impactful:
​​

• Cognitive changes – Including memory issues and slowed thinking.
• Mood disorders – Depression and anxiety are common.
• Sleep disturbances – Trouble falling or staying asleep, vivid dreams, or REM sleep behavior disorder.
• Autonomic dysfunction – Issues with involuntary body functions such as blood pressure regulation, digestion, and bladder control.
• Speech and swallowing difficulties – Soft speech, monotone voice, and difficulty swallowing are common in later stages.

Living Well With Parkinson’sAlthough there is no cure for Parkinson’s, many people live long, meaningful lives with proper care. Early diagnosis, medical treatment, regular exercise, and a supportive community can significantly improve quality of life.

One organization leading the way in whole-person care is the Parkinson’s Association of Southwest Florida (PASWFL).

How PASWFL Supports the Body and MindFor over 25 years, PASWFL has been dedicated to improving life for individuals touched by Parkinson’s disease and related neurological conditions. Offering more than 25 free programs and support groups weekly, PASWFL helps members and their care partners manage both the motor and non-motor symptoms of PD.

These programs include:

• Therapeutic exercise and balance classes
