Parkinson’s Disease

Parkinson’s Disease is a progressive neurological disorder that affects movement, balance, and coordination due to the loss of dopamine-producing brain cells. According to the World Health Organisation (WHO), over 8.5 million people worldwide are living with Parkinson’s disease, making it one of the fastest-growing neurological conditions globally. This page explains what Parkinson’s disease is, its symptoms, causes, and how it is diagnosed and managed, and how health Insurance plays an important role in dealing with Parkinson's.

Parkinson’s Disease is a progressive neurological disorder that occurs when nerve cells in the brain responsible for producing dopamine gradually deteriorate, leading to problems with movement, coordination, and muscle control. It commonly causes symptoms such as tremors, stiffness, slow movement, and balance issues. In simple terms, Parkinson’s disease affects how smoothly a person can move, making everyday actions like walking, writing, or speaking slower and more difficult over time.

Parkinson’s disease affects the brain by gradually damaging nerve cells in an area called the substantia nigra, which is responsible for producing dopamine, which is a chemical that helps control movement. As dopamine levels drop, communication between the brain and muscles weakens, leading to symptoms like tremors, stiffness, slow movement, and balance problems.

Parkinson’s disease can be classified into different types based on its cause, symptoms, and progression.

• Idiopathic Parkinson’s Disease

The most common form, with no known cause, usually develops gradually and responds well to medication.

• Secondary Parkinsonism

Caused by factors such as medications, toxins, infections, or head injuries rather than natural brain degeneration.

• Atypical Parkinsonism (Parkinson-plus syndromes)

Includes conditions like Multiple System Atrophy and Progressive Supranuclear Palsy, which progress faster and respond poorly to standard treatment.

• Vascular Parkinsonism

Develops due to multiple small strokes affecting brain areas responsible for movement.

• Juvenile or Young-Onset Parkinson’s

Occurs in younger individuals, often before the age of 40, and is usually linked to genetic factors.

Parkinson’s disease progresses gradually and is commonly divided into 5 stages based on the severity of symptoms and their impact on daily life.

• Stage 1: Mild symptoms affecting one side of the body, such as slight tremors or changes in posture, with minimal impact on daily activities.

• Stage 2: Symptoms appear on both sides of the body, including stiffness and slow movement, but balance is usually unaffected.

• Stage 3: Balance begins to worsen, movements become slower, and daily tasks become more difficult, though the person can still live independently.

• Stage 4: Severe symptoms with significant mobility issues; assistance is needed for most daily activities.

• Stage 5: Advanced stage where the person may be unable to walk or stand without support and requires full-time care.

Parkinson’s disease develops due to gradual damage to nerve cells in the brain that control movement, leading to reduced dopamine levels.

• Loss of dopamine-producing brain cells, which affects movement and coordination

• Age-related degeneration, with risk increasing after the age of 60

• Genetic factors that may increase susceptibility in some individuals

• Environmental exposure to toxins or chemicals over time

• A combination of genetic and environmental triggers rather than a single cause

Certain factors can increase a person’s likelihood of developing Parkinson’s disease, although the exact cause may vary from individual to individual.

• Age: Risk increases significantly after the age of 60

• Genetics: Family history can raise the chances of developing the condition

• Gender: Men are more likely to develop Parkinson’s than women

• Environmental exposure: Long-term exposure to pesticides, chemicals, or toxins

• Head injuries: Repeated or severe head trauma may increase risk

• Lifestyle factors: Limited physical activity and long-term exposure to pollutants may contribute

Parkinson’s disease causes both movement-related and non-motor symptoms that gradually worsen over time.

• Tremors: Shaking of hands, fingers, or limbs, usually starting on one side

• Slowness of movement (Bradykinesia): Difficulty in initiating and performing movements

• Muscle stiffness: Rigid muscles cause pain and reduced range of motion

• Impaired balance and posture: Increased risk of falls

• Changes in speech and writing: Soft voice, slurred speech, or small handwriting

• Fatigue and sleep problems: Ongoing tiredness and disturbed sleep

• Non-motor symptoms: Depression, anxiety, constipation, and memory or concentration issues

Parkinson’s disease is primarily diagnosed based on medical history, symptoms, and neurological examination, as there is no single test that can confirm it definitively.

• Clinical evaluation

A neurologist assesses movement, reflexes, coordination, and balance

• Medical history review

Symptoms, progression, and family history are carefully examined.

• Response to medication

Improvement with Parkinson’s medicines can help support the diagnosis

• Imaging tests

MRI or CT scans may be used to rule out other conditions, though they do not confirm Parkinson’s

• DaTscan (in some cases)

Helps assess dopamine activity in the brain when the diagnosis is unclear

Treatment for Parkinson’s disease focuses on managing symptoms, improving quality of life, and slowing functional decline. While there is no cure yet, research-backed therapies and medical management help control symptoms effectively.

1. Medications

The primary treatment involves medicines that increase or mimic dopamine levels in the brain. Levodopa remains the most effective drug and is commonly prescribed to improve movement, stiffness, and tremors. Other medications help regulate dopamine activity or reduce its breakdown, improving symptom control over time.

2. Surgical Treatment (Deep Brain Stimulation DBS)

In advanced cases where medications become less effective, Deep Brain Stimulation may be recommended. This procedure involves implanting electrodes in specific brain areas to regulate abnormal signals and reduce motor symptoms. Clinical studies have shown DBS to significantly improve the quality of life in suitable patients.

3. Physiotherapy and Occupational Therapy

Regular physiotherapy helps maintain mobility, balance, and muscle strength. Occupational therapy supports patients in performing daily activities independently and safely.

4. Speech and Swallowing Therapy

Speech therapy helps manage voice changes and swallowing difficulties, which are common as the disease progresses.

5. Ongoing Research and Emerging Treatments

Research is ongoing in areas such as gene therapy, stem cell therapy, and neuroprotective drugs aimed at slowing disease progression, with several clinical trials showing promising results.

Lifestyle changes play an important role in managing Parkinson’s disease and improving daily functioning alongside medical treatment.

• Regular exercise

Helps improve mobility, balance, and muscle strength while reducing stiffness.

• Healthy diet

A balanced diet with fibre, fluids, and nutrients supports digestion and overall health.

• Speech and movement therapy

Helps maintain communication skills and physical independence.

• Good sleep habits

Proper rest helps manage fatigue and other non-motor symptoms.

• Mental well-being

Stress management, counselling, and social support improve emotional health.

• Home safety measures

Simple modifications reduce the risk of falls and injuries.

As Parkinson’s disease progresses, it can lead to several complications that affect both physical and mental health.

• Mobility problems: Increased difficulty in walking, balance issues, and a higher risk of falls

• Swallowing difficulties: Can lead to choking or aspiration-related infections

• Speech problems: Soft or slurred speech affecting communication

• Cognitive changes: Memory issues, confusion, or dementia in later stages

• Mental health concerns: Depression, anxiety, and mood changes

• Sleep disorders: Insomnia, daytime sleepiness, and restless sleep

• Digestive issues: Constipation and slower digestion

• Autonomic dysfunction: Blood pressure fluctuations, urinary problems, and excessive sweating

While Parkinson’s disease cannot be completely prevented, maintaining a healthy lifestyle may help reduce risk. Regular physical activity, a balanced diet, and avoiding exposure to toxins support brain health. Protecting against head injuries and managing stress can also contribute to better neurological well-being.

Health insurance typically covers Parkinson’s disease under neurological or chronic illness benefits, including consultation, diagnostic tests, medications, and hospitalisation. Treatment costs such as long-term medication, physiotherapy, and in some cases, surgery like Deep Brain Stimulation may be covered depending on the policy. Coverage usually applies after the waiting period, especially if Parkinson’s is classified as a pre-existing condition.
