What is Parkinson's disease?
Parkinson's disease is a progressive neurological disorder that gradually impairs a patient’s movement. The disease develops when nerve cells in a part of the brain called the substantia nigra become damaged or die. It plays an essential role in producing dopamine, a chemical that helps control smooth and coordinated muscle movements.
The reduction in dopamine leads to various symptoms. They include tremor (shaking of the body, particularly the hands), rigidity (stiffness of the body), slowed movement, difficulty maintaining balance, etc. In certain situations, speech disorders and a lack of facial expressions might also be observed.
What are the Types of Parkinson's disease?
There are mainly four types of Parkinson's disease classified based on their cause and development. These include:
-
Idiopathic (Primary) Parkinson’s Disease
This is the most common type of Parkinson's disease. In most cases, the cause of the illness remains unknown. The gradual loss of neurons that generate dopamine causes the development of idiopathic Parkinson’s disease.
-
Viral Pneumonia
Viral pneumonia is linked to respiratory viruses such as influenza, RSV, and COVID-19. It may begin with symptoms that resemble a seasonal flu infection before gradually affecting the lungs more seriously. Although some cases remain mild, viral pneumonia can become severe in older adults and individuals with weak immunity.
-
Secondary Parkinsonism
Secondary Parkinsonism occurs due to an identifiable cause, such as certain medications, brain injuries, infections, toxins, or other medical conditions. Unlike idiopathic Parkinson’s, symptoms here are triggered by an external factor.
-
Atypical Parkinsonism
This group includes disorders like Multiple System Atrophy (MSA), Progressive Supranuclear Palsy (PSP), and Corticobasal Degeneration (CBD) that have symptoms similar to Parkinson’s disease but are generally more complex and progress differently.
How Common is Parkinson's Disease in India?
Parkinson’s disease is one of the most common brain-related disorders in older adults, especially those above 60 years of age. In India, its impact is growing quickly and is becoming a major public health concern.
What is more worrying is the rapid rise in cases. Experts project that by 2050, Parkinson’s cases in India could increase by around 168%. This means the number of patients may grow sharply over the coming decades.
What are the Symptoms of Parkinson's Disease?
The symptoms of Parkinson’s disease usually develop slowly and can begin with mild signs that are easy to overlook. In many cases, they first appear on one side of the body and then spread to both sides as the condition progresses. Over time, these symptoms can start affecting daily activities.
-
Movement-related Symptoms
Parkinson’s mainly affects body movement. Common signs include:
- Slowness in movement, making everyday tasks take longer
- Tremors are often seen when the hands, arms, or legs are at rest.
- Stiffness in the muscles
- Changes in walking and posture, such as a bent-forward posture, small shuffling steps, or difficulty turning
- Reduced facial expressions
- Softer voice or reduced speech volume
- Smaller or cramped handwriting over time
-
Non-movement Related Symptoms
Parkinson’s can also affect other body functions beyond movement. These may include:
- Reduced sense of smell
- Sleep disturbances
- Emotional changes such as anxiety or depression
- Digestive issues like constipation or urinary problems
NOTE: Not everyone experiences all symptoms, and severity can vary widely.
What Causes Parkinson's Disease?
Parkinson’s disease occurs when certain brain cells that produce dopamine gradually get damaged or die. This leads to low dopamine levels, which in turn affect movement and coordination.
The exact cause is not fully known, but several factors may contribute.
-
Genetic Factors
Parkinson’s disease can sometimes run in families due to changes in genes. These gene changes can increase the risk of the disease, but they do not always cause it directly. In most cases, Parkinson’s is not inherited, but genetics can still make a person more likely to develop it.
-
Environmental Factors
Long-term exposure to certain toxins, such as pesticides or other harmful chemicals, may increase the risk. However, no single environmental cause has been confirmed.
-
Changes Inside the Brain
Several internal changes are seen in people with Parkinson’s:
- Lewy Bodies: Harmful clumps of protein that build up in brain cells and affect their function.
- Alpha-synuclein Protein: A protein that misfolds and accumulates, contributing to cell damage.
- Mitochondrial Problems: Damage to the cell’s energy system, which reduces energy and leads to cell death.
These changes together affect how brain cells work and gradually lead to symptoms of the disease.
Risk Factors of Parkinson's Disease
The risk of developing Parkinson’s disease increases due to certain factors that are listed below:
-
Age: The risk of Parkinson's disease rises with age. It usually develops after age 50, and most people are diagnosed between 60 and 70 years. It is uncommon in younger people, but when it occurs before 50, it is called early-onset Parkinsons disease.
-
Gender: It affects more men than women. The exact cause of this difference is not known, but research shows an increased risk in men compared to women.
-
Family History: Having a close family member, such as a parent or sibling, with Parkinsons slightly increases your risk.
-
Exposure to Toxins: Exposure to various toxins, especially pesticides and herbicides, over long periods may increase one risk.
When Should I See My Healthcare Provider?
You should consult a healthcare provider if you notice any of the following:
-
When simple activities such as walking and writing take longer and are more difficult.
-
When you observe any shaking of your hands, fingers, or other body parts when you are not doing anything.
-
When you feel dizzy while standing and walking, or even have several falls.
-
When you assume a stooped posture.
-
When you have difficulty making expressions, talking softly, and loss of sense of smell.
How is Parkinson's disease diagnosed?
Parkinson’s disease is diagnosed mainly based on symptoms, medical history, and neurological examination. There is no single test that can confirm it with certainty, so doctors use a combination of methods to reach a diagnosis.
-
Medical History Review: In this procedure, a doctor evaluates symptoms and their progression, together with a possible family history of such disorders.
-
Neurological Examination: Movement, balance, muscle stiffness, reflexes, and coordination are assessed to look for typical signs of the disease.
-
Imaging Tests: In order to exclude the presence of another neurological disorder, an MRI is performed.
-
DaTscan: This scan helps measure dopamine activity in the brain. It can support the diagnosis by showing reduced dopamine function, although it is not used alone to confirm the disease.
How is Parkinson's disease managed?
To manage Parkinson’s disease, the focus should be on controlling symptoms and improving daily functioning. It does not cure the condition, but it helps people stay active and independent for longer.
-
Medications
Medication is the most common treatment for patients suffering from this disorder. The majority of the drugs available increase dopamine or help it function in the brain, thus reducing problems related to body movements such as muscle rigidity, tremors, and slow walking. Examples of medication are carbidopa-levodopa, dopamine agonists, and MAO-B inhibitors.
-
Infusion Therapies
Infusion therapies can also be used when oral medications are insufficient to manage the condition. The medication is continuously delivered through a small pump under the skin, helping reduce 'on-off' fluctuations in movement control.
-
Therapy and Rehabilitation
Rehabilitation therapies play an important role in maintaining patients’ mobility and independence. Physical therapy aims to improve balance, strength, and walking. Occupational therapy helps perform daily activities like dressing and writing. Speech therapy helps with speech clarity and swallowing difficulties.
-
Surgery
In certain situations when medications fail to have an effect, surgery may become necessary. Such procedures include deep-brain stimulation (DBS). It means implanting a device into specific parts of the brain to alleviate symptoms related to movement. It can improve the quality of life, but does not stop the progression of the disease.
-
Lifestyle and Supportive Care
Healthy daily habits also make a difference. Regular exercise, balanced nutrition, good sleep, and emotional support can help manage symptoms.
Can Parkinson's Disease be Reversed?
Currently, it is impossible to reverse or cure Parkinson's disease due to its nature. Since the condition causes irreparable damage to brain cells which produce dopamine, this neurodegenerative disorder often develops slowly. However, treatments such as medications, therapy, lifestyle changes, and in some cases surgery can help control symptoms and improve quality of life. Early diagnosis and proper management may also help people stay active and independent for longer.
How Can I Prevent Parkinson's Disease?
There is no guaranteed way to prevent Parkinson’s disease because the exact cause is still not fully understood. However, certain healthy lifestyle habits may help support brain health and lower the risk.
-
Exercise Regularly: Physical activity may help protect brain function and improve overall health.
-
Eat a Balanced Diet: A nutritious diet rich in fruits, vegetables, whole grains, and healthy fats supports brain and body health.
-
Limit Exposure to Harmful Chemicals: Limiting contact with pesticides, herbicides, and toxins may reduce risk.
-
Manage Overall Health: Controlling conditions like high blood pressure, diabetes, and stress can support long-term brain health.
Does Health Insurance Cover Parkinson's Disease?
Yes, Parkinson’s disease is generally covered under health insurance, but the level of coverage depends on the type of policy.
Most standard health plans may cover hospitalisation, doctor consultations, neurological care, and diagnostic tests after the 30-day waiting period. However, policy terms can vary, so it is always important to carefully review the documents.
In some critical illness insurance plans, Parkinson’s disease is also covered, with a lump-sum payment upon diagnosis. This payout is usually made in a single transaction, provided the patient survives for at least 30 days after diagnosis.
In some critical illness insurance plans, Parkinson’s disease is also covered, with a lump-sum payment upon diagnosis. This payout is usually made in a single transaction, provided the patient survives for at least 30 days after diagnosis.
How Much Health Insurance Coverage is Needed for Parkinson's Disease Treatment?
The amount of health insurance coverage required for Parkinson’s disease depends on the stage of the condition, treatment needs, and long-term care requirements.
Since it is a progressive neurological disorder, treatment is often lifelong and may include regular medications, specialist consultations, hospital visits, rehabilitation therapies, and in some cases, advanced procedures like deep brain stimulation.
In most cases, a sum insured of ₹15 lakhs is sufficient to cover long-term treatment needs. For individuals who may require advanced care, higher coverage amounts, or a critical illness plan, it can provide better financial cover.
