What Is Parkinson’s Disease? What Are Its Symptoms?

Overview
Parkinson’s disease is the second most common neurodegenerative disorder after Alzheimer’s disease. It is usually age-related and characterized by movement disorders, balance difficulties, and progressive neurological decline. While the exact cause is not fully understood, both genetic and environmental factors play a role.
Although Parkinson’s cannot be cured, various medical treatments and advanced procedures can help slow its progression and relieve symptoms, significantly improving quality of life. At MedicalPoint Hospital, our neurology and neurosurgery specialists provide comprehensive care for patients with Parkinson’s, combining medication, rehabilitation, and innovative therapies such as Deep Brain Stimulation (DBS).
What Is Parkinson’s Disease?
Parkinson’s disease is a neurodegenerative disorder that primarily affects nerve cells (neurons) in the substantia nigra, a region of the brain responsible for producing dopamine. Dopamine is a neurotransmitter essential for controlling movement, coordination, and emotional responses.
Symptoms usually appear after 60–80% of dopamine-producing cells are lost, meaning the disease often begins long before noticeable signs develop.
- Most cases occur after age 60, though early-onset Parkinson’s can affect younger individuals.
- Incidence: ~1% of people over 60 and ~4% of people over 80 develop Parkinson’s.
- Men are more frequently affected than women.
Causes of Parkinson’s Disease: Is It Genetic?
The precise causes remain unclear, but research points to a combination of genetic, environmental, and lifestyle factors:
- Genetic risk – Around 10–15% of cases are linked to inherited gene mutations.
- Environmental triggers – Exposure to pesticides, solvents, or air pollution may increase risk.
- Head trauma – Severe brain injuries may contribute to onset.
- Aging – Natural decline in dopamine neurons with age is the strongest risk factor.
In most cases, Parkinson’s develops from multiple interacting factors, not a single cause.
Symptoms of Parkinson’s Disease
Parkinson’s disease progresses slowly, and symptoms vary among individuals. It is characterized by motor symptoms (movement-related) and non-motor symptoms (unrelated to movement).
Motor Symptoms
- Bradykinesia (slowness of movement)
- Muscle stiffness (rigidity)
- Resting tremor – rhythmic shaking, usually in the hands
- Postural instability – stooped posture, balance issues, frequent falls
- Gait changes – short, shuffling steps, reduced arm swing
- Speech difficulties – low or monotone voice (hypophonia)
- Facial masking – reduced facial expressions (hypomimia)
- Handwriting changes – small, cramped writing (micrographia)
Non-Motor Symptoms
These can appear years before movement problems and often serve as early warning signs:
- Constipation and digestive issues
- Urinary problems or incontinence
- Loss of sense of smell (anosmia)
- Sleep disorders (insomnia, restless legs, REM sleep behavior disorder)
- Orthostatic hypotension (drop in blood pressure when standing)
- Depression, anxiety, or apathy
- Cognitive decline, memory issues, and Parkinson’s dementia in later stages
Stages of Parkinson’s Disease
Doctors often classify Parkinson’s into five stages to understand its progression:
- Stage 1 – Mild symptoms on one side of the body; daily activities are not significantly affected.
- Stage 2 – Symptoms appear on both sides; walking and posture changes become noticeable.
- Stage 3 – Mid-stage with balance difficulties and increased risk of falls; independence still possible.
- Stage 4 – Severe symptoms; walking aids may be needed; daily activities require assistance.
- Stage 5 – Advanced stage; severe disability; continuous care is necessary.
How Is Parkinson’s Disease Diagnosed?
There is no single test to confirm Parkinson’s. Diagnosis is based on:
- Medical history – Reviewing symptoms and risk factors.
- Neurological examination – Assessing movement, reflexes, and balance.
- Imaging tests (MRI, PET scans) – Used mainly to exclude other conditions rather than confirm Parkinson’s.
Because Parkinson’s can resemble other disorders, specialist evaluation by a neurologist is essential. At MedicalPoint Hospital, patients undergo detailed neurological assessments supported by advanced imaging technologies.
How Is Parkinson’s Disease Treated?
Although there is no cure, effective treatment can manage symptoms and improve quality of life.
1. Medications
- Levodopa (with carbidopa) – The most effective treatment; converts into dopamine in the brain.
- Dopamine agonists – Mimic dopamine effects.
- MAO-B inhibitors – Prevent dopamine breakdown.
- Other drugs – To manage tremors, stiffness, and non-motor symptoms.
2. Surgical Options
- Deep Brain Stimulation (DBS) – Electrodes implanted in specific brain areas deliver electrical impulses to regulate abnormal activity.
- Reduces tremors, stiffness, and involuntary movements.
- Effective for patients whose symptoms are not well controlled with medication.
- Available at MedicalPoint Hospital, performed by experienced neurosurgeons.
3. Lifestyle and Supportive Care
- Physical therapy – Improves strength, flexibility, and balance.
- Speech therapy – Helps with voice projection and swallowing difficulties.
- Dietary adjustments – High-fiber foods and adequate hydration reduce constipation.
- Mental health care – Counseling and support groups help manage depression or anxiety.
