Understanding Parkinson’s Disease

Parkinson’s disease is a progressive neurological condition that primarily affects movement. It develops gradually, often beginning with subtle symptoms such as a slight tremor or stiffness before progressing over time.

Although there is currently no cure, many people with Parkinson’s disease continue to live active, fulfilling lives with the right combination of medication, rehabilitation, exercise and ongoing support.

At St Giles Medical Rehabilitation Centre, rehabilitation plays an important role in helping individuals maintain mobility, independence and quality of life throughout their Parkinson’s journey.

What Is Parkinson’s Disease?

Parkinson’s disease is a disorder of the nervous system caused by the gradual loss of nerve cells in a part of the brain called the substantia nigra.

These nerve cells produce dopamine, a chemical messenger that helps control smooth, coordinated movement. As dopamine levels decrease, movement becomes slower, muscles become stiffer, and balance and coordination may be affected.

Parkinson’s disease is progressive, meaning symptoms gradually change over time. However, the rate of progression varies from person to person.

What Causes Parkinson’s Disease?

The exact cause of Parkinson’s disease remains unknown.

Researchers believe it results from a combination of genetic and environmental factors.

Possible contributing factors include:

Increasing age
Family history of Parkinson’s disease
Certain genetic mutations
Long-term exposure to some environmental toxins
Previous head injuries (in some cases)

Most people diagnosed with Parkinson’s disease have no clear family history.

Common Symptoms

Symptoms usually develop gradually and often begin on one side of the body before affecting both sides.

Movement Symptoms

Tremors, especially at rest
Muscle stiffness (rigidity)
Slowness of movement (bradykinesia)
Difficulty walking
Poor balance
Reduced arm swing while walking
Shuffling gait
Smaller handwriting (micrographia)

Non-Movement Symptoms

Parkinson’s affects more than movement.

Some people experience:

Depression
Anxiety
Sleep disturbances
Constipation
Fatigue
Reduced sense of smell
Memory and thinking difficulties
Soft or quiet speech
Difficulty swallowing

Stages of Parkinson’s Disease

Symptoms often progress gradually.

Although every individual is different, Parkinson’s generally progresses through five stages:

Stage 1

Mild symptoms
Usually affects one side of the body
Daily activities remain largely unaffected

Stage 2

Symptoms affect both sides
Walking may become slower
Muscle stiffness increases

Stage 3

Balance problems become more noticeable
Falls become more likely
Most people remain independent

Stage 4

Walking often requires assistance
Daily activities become more challenging

Stage 5

Significant mobility limitations
Full-time assistance may be required

Not everyone progresses through these stages at the same pace.

How Is Parkinson’s Disease Diagnosed?

There is currently no single test for Parkinson’s disease.

Doctors diagnose Parkinson’s by reviewing:

Medical history
Symptoms
Physical examination
Movement assessment
Neurological examination

Brain imaging may sometimes be used to rule out other conditions.

Treatment Options

Although Parkinson’s cannot currently be cured, treatment can effectively manage symptoms.

Treatment may include:

Medication to increase dopamine activity
Regular exercise
Physiotherapy
Occupational therapy
Speech and language therapy
Healthy lifestyle changes
In selected cases, surgery such as Deep Brain Stimulation (DBS)

Treatment plans are tailored to each individual.

Why Rehabilitation Is Essential

Medication helps control symptoms, but rehabilitation helps people maintain independence.

Research shows that regular rehabilitation can improve:

Walking
Balance
Strength
Flexibility
Confidence
Communication
Daily living skills

Early rehabilitation often leads to better long-term outcomes.

Accessing available services

Living Well with Parkinson’s Disease

Although Parkinson’s is progressive, many people continue to lead meaningful and active lives.

Helpful lifestyle habits include:

Exercising regularly
Taking medication as prescribed
Maintaining social connections
Eating a balanced diet
Prioritising sleep
Managing stress
Attending rehabilitation appointments consistently

Small daily habits can make a significant difference over time.

Frequently Asked Questions

Is Parkinson’s disease curable?

There is currently no cure, but treatments can effectively manage symptoms and improve quality of life.

Does everyone with Parkinson’s have tremors?

No. While tremors are common, some people mainly experience stiffness or slowed movement.

Can exercise slow the progression of Parkinson’s?

Exercise cannot cure Parkinson’s, but research suggests regular physical activity may help maintain mobility, improve function and reduce disability.

Can younger people develop Parkinson’s disease?

Yes. Although it most commonly affects older adults, younger people can also develop Parkinson’s disease.

Is Parkinson’s disease hereditary?

Most cases are not directly inherited, although genetics may contribute in some individuals.
