Parkinson’s Disease
Parkinson’s disease is a progressive brain disorder that affects movement, causing symptoms such as tremors, stiffness, and difficulty with balance and coordination.
What is Parkinson’s Disease?
Parkinson’s disease is a progressive brain disorder that affects movement, causing symptoms such as tremors, stiffness, and difficulty with balance and coordination. It usually develops gradually, starting with mild symptoms that worsen over time. As the disease progresses, it can lead to challenges with walking, talking, and completing everyday tasks. Parkinson’s can also cause mental and behavioural changes, such as sleep issues, depression, memory problems, and fatigue.
What Causes Parkinson’s Disease?
The condition is more common in men than in women, though the reason for this is not fully understood. The symptoms of Parkinson’s disease occur when nerve cells (neurons) in a part of the brain called the basal ganglia, which controls movement, become impaired or die. These neurons typically produce dopamine, a chemical that helps regulate movement. When these neurons are damaged, dopamine levels decrease, leading to the movement difficulties associated with the disease.
Signs and Symptoms of Parkinson’s Disease
Parkinson’s disease presents differently in each person, but common signs and symptoms include:
Tremor
Shaking, often beginning in the hands, arms, legs, jaw, or head.
Muscle Stiffness
Muscles may feel tight or contracted, leading to discomfort.
Slowed Movement (Bradykinesia)
Movements may become slower and more difficult to perform.
Impaired Balance and Coordination
Difficulty with balance, which can increase the risk of falls.
Facial Masking
A reduction in facial expressions, often giving a “masked” appearance.
Changes in Speech
Speech may become softer, slurred, or more monotone.
Loss of Smell
A diminished sense of smell can be one of the early signs.
Postural Changes
A tendency to hunch over, affecting posture.
Memory and Cognitive Changes
As the disease progresses, it may impact memory and cognitive functions.
Risk Factors for Parkinson’s Disease
While the exact cause of Parkinson’s disease is unknown, several risk factors have been identified:
Age
Parkinson’s is more common in older adults, typically starting around age 60 or older.
Gender
Men are about 1.5 times more likely to develop Parkinson’s than women.
Family History
Having a close relative with Parkinson’s slightly increases the risk of developing the disease.
Genetics
Specific gene mutations are linked to Parkinson’s, although they are relatively rare.
Environmental Factors
Exposure to certain environmental toxins, such as pesticides and heavy metals, may increase the risk.
Head Trauma
A history of repeated head injuries may be linked to a higher risk of Parkinson’s disease.
Diagnosis and Treatment for Parkinson’s Disease
Diagnosing Parkinson’s disease can be challenging as there is no specific test for the condition. A diagnosis is typically based on a thorough medical history and a neurological examination. The presence of at least two of the three main symptoms—tremor, bradykinesia, and muscle rigidity—can indicate Parkinson’s. Additional tests, such as imaging scans, may be used to rule out other conditions.
While there is no cure for Parkinson’s disease, several treatments can help manage symptoms:
Medication
The primary treatment for Parkinson’s is levodopa, a drug that the brain converts into dopamine. Other medications may be used to mimic dopamine’s effects or to manage non-movement symptoms. Only take medication that is prescribed or approved by your doctor or health care professional.
Surgery
For some patients, surgical procedures like deep brain stimulations (DBS) may be considered when meditation alone is not effective. DBS involves implanting electrodes in the brain to help control movement.
Therapies
Physical, occupational, and speech therapies can help patients maintain their independence and manage daily activities.
Living with Parkinson’s Disease
Living with Parkinson’s disease presents ongoing challenges, but with the right support and strategies, individuals can maintain a good quality of life. Staying active, eating a balanced diet, and keeping mentally engaged are crucial for managing the disease.
Caring for someone with Parkinson’s disease can be demanding, both physically and emotionally. Here are some tips to help caregivers provide effective support:
Medication Management
Ensure the medications are taken as prescribed and monitor for any side effects.
Safe Environment
Remove tripping hazards like carpeting, wires, and footstools to prevent falls. Install grab bars and railings where necessary.
Routine
Establish a daily routine to help the person feel secure and reduce stress.
Exercise
Encourage gentle exercise, such as walking or stretching, to maintain mobility and reduce stiffness.
Communication
Be patient and allow extra time for the person to speak and express themselves. Simplify tasks and break them down into manageable steps.
Mental Stimulation
Engage in activities that stimulate the mind, such as puzzles, reading, or listening to music.
Emotional Support
Listen and provide reassurance. Be attentive to signs of depression or anxiety and seek professional help if needed.

Additional Statistics
- Approximately 100,000 Canadians are living with Parkinson’s disease, and it is expected that this number will double by 2031 as the population ages
- Worldwide, more than 10 million people are currently living with Parkinson’s disease, making it one of the most common neurodegenerative disorders
- The economic impact of Parkinson’s disease in Canada is significant, with the total annual cost estimated to be over $558 million, including healthcare expenses, lost productivity, and informal caregiving
