As we recognize Parkinson's Awareness Month, it's a meaningful time to explore how our nervous system connects thoughts, actions, and movement. In Parkinson's disease, this communication network is disrupted, affecting how signals travel through the nerves. This change helps explain why movement becomes slower, stiffer, or less coordinated for many people living with the condition.
By learning how nerve health influences movement, we can focus on practical ways to support our body's natural systems and improve daily comfort.
Understanding the Nervous System and Parkinson's
The nervous system acts like a vast communication network millions of nerve cells send messages between the brain and body, controlling movement, mood, and more.
In Parkinson's disease, nerve cells in a specific area of the brain called the substantia nigra begin to malfunction. These cells normally produce dopamine, a neurotransmitter that enables smooth, controlled movement.
When dopamine levels drop, communication between the brain and muscles becomes less efficient. Think of it like a highway where a few lanes suddenly close signals slow down, and movement becomes more difficult.
The good news is that the nervous system has remarkable plasticity, or the ability to adapt. Research suggests that maintaining nerve health may support better function and mobility, even as Parkinson's progresses.
Common Symptoms Linked to Nerve Function
When nerve communication is disrupted, a range of motor and non-motor symptoms can appear. Understanding these can help patients and caregivers identify helpful management strategies.
1. Movement (Motor) Symptoms
- Tremors or shaking, often noticeable when resting
- Muscle stiffness that limits flexibility
- Slowed movements (bradykinesia) that require extra effort
- Balance difficulties that affect walking and posture
These symptoms occur when nerve pathways responsible for coordination and precision aren't transmitting signals effectively. Each person's experience may differ some may notice more tremors, others more stiffness.
2. Non-Motor Symptoms
Nerve health also affects many non-movement functions, including:
- Sleep quality and rest patterns
- Energy levels throughout the day
- Mood and emotional balance
- Memory and cognitive clarity
These symptoms highlight that nerve function impacts both body and mind, influencing overall well-being.
Everyday Ways to Support Nerve Health
Supporting your nervous system doesn't require complex routines, small, consistent habits can make a big difference.
1. Move Regularly
Regular physical activity is one of the most effective ways to support nerve health and motor function.
Consider:
- Short 10–15 minute walks, even indoors
- Seated exercises for mobility and range of motion
- Tai chi or gentle stretching to promote balance
- Yoga or slow-movement routines that combine relaxation with muscle activation
