Parkinson's disease is a progressive neurological condition caused by the loss of dopamine-producing brain cells. It primarily affects movement but also causes non-motor symptoms.
Parkinson's disease affects approximately 10 million people worldwide and is the second most common neurodegenerative disease after Alzheimer's. Prevalence increases with age, affecting about 1% of people over 60.
The disease results from progressive loss of dopamine-producing neurons in the substantia nigra. By the time motor symptoms appear, approximately 60-80% of these neurons have been lost.
Modern treatment with levodopa and other dopaminergic therapies effectively manages symptoms for many years. Research into disease-modifying therapies is a major focus.
People with Parkinson's Disease often experience the following symptoms.
A rhythmic shaking, typically starting in one hand, most pronounced at rest and decreasing with purposeful movement.
Slowness of movement that makes everyday tasks difficult — buttons, writing, and walking become laborious.
Increased muscle tone causing stiffness, often described as 'lead pipe' or 'cogwheel' rigidity.
Depression, constipation, REM sleep behaviour disorder, loss of smell, and cognitive changes often precede motor symptoms by years.
Certain factors may increase your likelihood of developing Parkinson's Disease.
Common approaches to managing parkinson's disease. Always consult a healthcare provider for personalized treatment.
The most effective treatment. Levodopa is converted to dopamine in the brain. The gold standard for motor symptoms.
Pramipexole, ropinirole, and rotigotine stimulate dopamine receptors directly, often used in early disease.
Selegiline and rasagiline prevent dopamine breakdown, providing mild symptom relief and possible neuroprotection.
Surgical implantation of electrodes in the brain for advanced disease with motor fluctuations not controlled by medication.
Clinical diagnosis based on the presence of bradykinesia plus rigidity, resting tremor, or both. Response to levodopa supports diagnosis. DaTscan imaging and MRI can help exclude other causes.
See a doctor if you notice a new tremor, stiffness, slowness of movement, changes in handwriting (smaller), reduced arm swing while walking, or loss of facial expression.
Steps that may help reduce the risk of developing or worsening parkinson's disease.
Regular exercise (associated with reduced risk)
Caffeine consumption (epidemiological association)
Avoid pesticide exposure
No proven prevention — early detection is key
If left untreated or poorly managed, parkinson's disease may lead to:
About 10-15% of cases have a genetic component. Most cases are sporadic with no clear genetic cause.
Strong evidence suggests regular exercise improves symptoms and may slow disease progression.
With modern treatment, many patients live near-normal lifespans. Quality of life is the main concern.
