Parkinson’s disease (PD) is a progressive neurological condition that affects movement and other functions. This guide explains the condition, its causes, symptoms, treatments, and how to manage living with it.
What is Parkinson’s Disease?
Parkinson’s disease is a disorder of the nervous system that primarily affects movement. It occurs when certain nerve cells (neurons) in the brain become damaged or die. These neurons produce dopamine, a chemical that helps control movement. As dopamine levels decrease, it leads to symptoms such as tremors, stiffness, and difficulty with balance and coordination.
PD is a progressive condition, meaning symptoms worsen over time. While there is no cure, treatments are available to manage symptoms and improve quality of life.
Key Facts About Parkinson’s Disease
Background
- Parkinson’s disease was first described by Dr James Parkinson in 1817 in his essay “An Essay on the Shaking Palsy.”
- It is classified as a neurodegenerative disorder, meaning it involves the gradual loss of nerve cells in the brain.
Causes
- The exact cause of Parkinson’s disease is unknown, but it likely involves a combination of genetic and environmental factors:
- Genetic Factors: Mutations in specific genes (e.g., LRRK2, PARK7, PINK1, SNCA) can increase the risk of developing PD.
- Environmental Factors: Exposure to toxins such as pesticides or heavy metals may contribute to the disease in some individuals.
Incidence and Prevalence
- Incidence: Around 10–18 new cases per 100,000 people are diagnosed each year globally.
- Prevalence: Approximately 1 in 500 people are living with Parkinson’s disease, with higher rates seen in older populations.
Who is Affected?
- Age: PD most commonly develops after age 60, although early-onset cases can occur before age 50.
- Gender: Men are about 1.5 times more likely than women to develop Parkinson’s disease.
- Ethnicity: PD occurs worldwide and affects all ethnic groups, though prevalence may vary slightly between populations.
How Does Parkinson’s Disease Impact You?
Symptoms
The symptoms of Parkinson’s disease can vary from person to person but generally fall into two categories:
Motor Symptoms (Movement-related):
- Tremors (shaking), often starting in one hand or arm when at rest.
- Muscle stiffness (rigidity), making movement difficult or painful. Slowness of movement (bradykinesia), leading to difficulty initiating or completing tasks.
- Problems with balance or posture, increasing the risk of falls.
Non-Motor Symptoms (Other effects):
- Sleep disturbances (e.g., insomnia or acting out dreams).
- Cognitive changes such as memory problems or difficulty concentrating.
- Mood disorders like depression or anxiety.
- Constipation or other digestive issues.
Living With Parkinson’s Disease
Living with PD requires adapting to changes over time while managing symptoms through medical care and lifestyle adjustments.
Expected Life Expectancy
While Parkinson’s disease itself does not significantly reduce life expectancy, complications such as falls or infections may impact overall health if not managed effectively.
Managing and Treating Parkinson’s Disease
Available Treatments
Although there is no cure for PD, treatments aim to manage symptoms and improve quality of life:
- Medications:
- Levodopa/Carbidopa: The most effective treatment for motor symptoms; levodopa converts to dopamine in the brain, while carbidopa prevents side effects like nausea.
- Dopamine Agonists: Mimic dopamine’s effects in the brain (e.g., pramipexole, ropinirole).
- MAO-B Inhibitors: Slow down the breakdown of dopamine (e.g., selegiline, rasagiline).
- COMT Inhibitors: Prolong the effects of levodopa by blocking its breakdown.
- Other medications may address specific symptoms like tremors or non-motor issues.
- Surgical Treatments:
- Deep Brain Stimulation (DBS): A surgical procedure where electrodes are implanted in specific areas of the brain to improve motor symptoms.
- Physical Therapy and Exercise:
- Regular exercise can improve flexibility, strength, and balance.
- Speech therapy may help with voice changes or swallowing difficulties.
- Lifestyle Changes:
- Eating a balanced diet rich in fibre can help manage constipation.
- Maintaining an active lifestyle can improve overall well-being.
- Supportive Therapies:
- Occupational therapy can help adapt daily activities to changing abilities.
- Psychological support may be beneficial for managing depression or anxiety.
Ongoing Clinical Research
Research into Parkinson’s disease continues to explore new treatments and potential cures:
- Gene Therapy:Scientists are investigating ways to modify genes associated with PD to slow or stop its progression.
- Stem Cell Therapy: Studies are underway to determine whether stem cells can replace damaged neurons and restore dopamine production.
- Neuroprotective Drugs: Researchers are testing medications that could protect nerve cells from further damage.

Support Groups and Resources
If you have been diagnosed with Parkinson’s disease, connecting with support groups can provide valuable information and emotional support:
- Parkinson’s UK (org.uk)– Offers resources for patients and families living with PD.
- Michael J. Fox Foundation for Parkinson’s Research (org)– Focuses on advancing research for better treatments and cures.
- European Parkinson’s Disease Association (EPDA) (eu.com)– Provides advocacy and education for individuals living with PD across Europe.
- American Parkinson Disease Association (APDA) (org)– Offers support services for people affected by PD.Remember:This information is intended for general knowledge and educational purposes only and does not constitute medical advice.
