Parkinson’s Disease: Symptoms, Causes and Treatment

Spreading awareness about Parkinson’s disease is essential for fostering understanding, promoting early detection and intervention, driving research advancements, advocating for patient needs, and creating a more supportive and inclusive society for individuals living with Parkinson’s and their families.

Q) What is Parkinson’s disease?

Ans) Parkinson’s disease is a progressive neurodegenerative disorder that affects movement control. It is named after Dr. James Parkinson, who first described the condition in 1817. Parkinson’s disease is characterized by the gradual loss of dopamine-producing neurons in the substantia nigra region of the brain. Dopamine is a neurotransmitter that plays a key role in regulating movement and emotional responses. The exact cause of Parkinson’s disease is not fully understood, but it is believed to involve a combination of genetic and environmental factors.

Diagnosing Parkinson’s disease involves a thorough medical history review, physical examination, and assessment of symptoms. There are no specific tests to definitively diagnose Parkinson’s disease, so doctors rely on clinical criteria and rule out other conditions that may mimic its symptoms. Neuroimaging techniques like MRI and DaTscan can help in confirming the diagnosis by detecting changes in the brain’s structure and dopamine activity.

Q) Who is more prone to developing Parkinson’s disease?

Ans) Parkinson’s disease affects individuals from diverse backgrounds, but certain factors may increase the risk of developing the condition. Understanding these risk factors is essential for identifying vulnerable populations and implementing preventive strategies.

  1. Age: Advancing age is one of the primary risk factors for Parkinson’s disease. The prevalence of Parkinson’s increases with age, with the majority of cases diagnosed in individuals over 60 years old. However, it’s important to note that younger individuals can also develop Parkinson’s, albeit less frequently.
  1. Genetics and Family History: Genetic factors play a significant role in Parkinson’s disease, although most cases are sporadic rather than directly inherited. Individuals with a family history of Parkinson’s disease have a higher risk of developing the condition compared to those without such a history. Specific genetic mutations, such as mutations in the SNCA, LRRK2, and Parkin genes, have been identified as risk factors for Parkinson’s disease. However, genetic testing is not routinely recommended for assessing Parkinson’s risk in the general population due to the complex interplay of genetic and environmental factors.
  1. Environmental Exposures: Exposure to certain environmental toxins and chemicals has been linked to an increased risk of Parkinson’s disease. Pesticides and herbicides, such as paraquat and rotenone, are among the substances associated with a higher prevalence of Parkinson’s. These chemicals can disrupt dopamine-producing neurons in the brain, contributing to the development of the disease. Other environmental factors, such as head injuries and viral infections, have also been implicated in Parkinson’s disease risk.
  1. Lifestyle Factors: Several lifestyle factors may influence the risk of developing Parkinson’s disease. Excessive alcohol consumption and a sedentary lifestyle may increase the risk of Parkinson’s disease. Maintaining a healthy lifestyle that includes regular physical activity, a balanced diet, and avoiding harmful substances can help mitigate some of the risk factors associated with Parkinson’s.
  1. Medical Conditions and Medications: Certain medical conditions and medications have been linked to an increased risk of Parkinson’s disease. Additionally, exposure to antipsychotic medications, particularly older drugs like haloperidol, has been associated with a higher risk of Parkinson’s disease. Healthcare providers need to consider these factors when assessing an individual’s risk profile for Parkinson’s.

Understanding these risk factors enables healthcare professionals to identify high-risk populations, implement targeted preventive measures, and develop personalized treatment strategies for individuals diagnosed with Parkinson’s disease.

Q)What are the symptoms and treatments for Parkinson’s disease?

Ans) Symptoms of Parkinson’s Disease:

Parkinson’s disease is characterized by a range of motor and non-motor symptoms that can significantly impact an individual’s quality of life. These symptoms may vary in severity and progression among affected individuals.

Motor Symptoms:

  • Tremors: Involuntary shaking of hands, arms, legs, jaw, or face, particularly at rest. Tremors often start on one side of the body and may progress to affect both sides as the disease advances.
  • Bradykinesia: Slowed movement and difficulty initiating voluntary movements. This can manifest as reduced arm swing while walking, stiffness in muscles, and overall slowness in daily activities.
  • Muscle Rigidity: Stiffness and inflexibility in muscles, leading to reduced range of motion and difficulty with fine motor tasks.
  • Postural Instability: Impaired balance and coordination, increasing the risk of falls. Individuals with Parkinson’s disease may experience difficulty in maintaining an upright posture and may have a stooped or hunched appearance.

Non-Motor Symptoms:

  • Cognitive Changes: Parkinson’s disease can lead to cognitive impairment, including difficulties with memory, attention, and executive function. Some individuals may develop dementia in the later stages of the disease.
  • Mood Disorders: Depression and anxiety are common in people with Parkinson’s disease. Changes in neurotransmitter levels and the impact of the disease on daily life can contribute to mood disturbances.
  • Sleep Disturbances: Many individuals with Parkinson’s experience sleep problems, such as insomnia, restless leg syndrome, and rapid eye movement (REM) sleep behaviour disorder, which involves acting out dreams during sleep.
  • Autonomic Dysfunction: Parkinson’s can affect the autonomic nervous system, leading to symptoms like constipation, urinary problems, low blood pressure upon standing (orthostatic hypotension), and sweating abnormalities.

Treatment of Parkinson’s Disease:

While there is currently no cure for Parkinson’s disease, various treatment options are available to manage symptoms, improve quality of life, and slow disease progression.


  • Levodopa: Levodopa is the most effective medication for managing motor symptoms of Parkinson’s disease. It is converted into dopamine in the brain, replenishing dopamine levels and improving movement.
  • Dopamine Agonists: These medications mimic the action of dopamine in the brain, helping to alleviate motor symptoms.
  • MAO-B Inhibitors: Monoamine oxidase type B (MAO-B) inhibitors prevent the breakdown of dopamine in the brain, prolonging its effects and reducing motor fluctuations.
  • COMT Inhibitors: Catechol-O-methyltransferase (COMT) inhibitors enhance the effectiveness of levodopa by preventing its breakdown, thus extending its duration of action.
  • Anticholinergics: These medications can help reduce tremors and muscle rigidity by blocking the effects of acetylcholine, another neurotransmitter in the brain.

Deep Brain Stimulation (DBS):

Deep Brain Stimulation is a surgical procedure that involves implanting electrodes in specific brain areas, such as the subthalamic nucleus or globus pallidus, and connecting them to a pulse generator placed under the skin. The electrodes deliver electrical impulses to modulate abnormal brain activity and improve motor symptoms. DBS is often recommended for individuals with advanced Parkinson’s disease who have significant medication-related fluctuations or tremors that are not adequately controlled by medications alone.

Physical Therapy and Exercise:

Physical therapy and exercise programs play a crucial role in managing Parkinson’s disease. They can help improve mobility, balance, flexibility, and muscle strength. Occupational therapy may also be beneficial for addressing daily living activities and fine motor skills. Regular exercise, such as walking, swimming, and tai chi, can contribute to overall physical and mental well-being in individuals with Parkinson’s.

Lifestyle Modifications:

Certain lifestyle modifications can complement medical treatment and improve symptom management in Parkinson’s disease. These include:

  • Healthy Diet: A balanced diet rich in fruits, vegetables, whole grains, and lean proteins can support overall health and may have neuroprotective effects.
  • Speech Therapy: Speech therapy can help individuals with Parkinson’s improve communication, swallowing, and voice projection.
  • Stress Management: Techniques such as mindfulness, relaxation exercises, and counselling can help individuals cope with stress and emotional challenges associated with Parkinson’s.
  • Social Support: Engaging in social activities, and support groups, and maintaining strong social connections can provide emotional support and improve quality of life.

Individuals with Parkinson’s disease need to work closely with doctors to develop a personalized treatment plan tailored to their specific needs and symptoms. Regular monitoring, adjustments to medications, and ongoing support can help optimize outcomes and enhance the quality of life for individuals living with Parkinson’s.

Q) How can you prevent yourself from getting Parkinson’s disease?

Ans) While there is currently no known way to prevent Parkinson’s disease entirely, there are several strategies and lifestyle factors that may help reduce the risk of developing the condition or delay its onset.
