Definition

Parkinson’s disease is a progressive neurological disorder that primarily affects voluntary movements.

Symptoms

The symptoms of Parkinson’s disease can differ between individuals and often begin on one side of the body. Early signs are usually mild and may go unnoticed. Common symptoms include:

• Tremor – Shaking in a limb, often in the hand or fingers when at rest; a characteristic “pill-rolling” motion of the thumb and forefinger.
• Bradykinesia (slowed movement) – Difficulty with movement and walking, dragging feet, taking smaller steps, and challenges rising from a chair or bed.
• Orthostatic hypotension – Feeling lightheaded or dizzy when standing.
• Muscle rigidity – Stiffness in muscles causing pain and limiting movement.
• Impaired posture and balance – Stooped posture and unsteady balance.
• Loss of automatic movements – Reduced facial expressions, less blinking, diminished arm swing while walking.
• Speech difficulties (dysarthria) – Speaking softly, quickly, with slurring, hesitation, or monotone speech.
• Swallowing difficulties (dysphagia) – Trouble swallowing food or liquids.
• Changes in handwriting – Writing may become small and difficult to read.

Risk Factors

Factors that increase the risk of developing Parkinson’s disease include:

• Age – Most cases develop after the age of 60.
• Heredity – Family history increases the likelihood.
• Sex – Men are more commonly affected than women.
• Exposure to toxins – Long-term exposure to pesticides or herbicides may contribute.

Diagnosis

There is no single definitive test for Parkinson’s disease. Diagnosis typically involves:

• Detailed medical history and assessment of signs and symptoms.
• Neurological and physical examinations.
• Blood tests to rule out other conditions.
• Imaging tests, such as MRI, brain ultrasound, SPECT, or PET scans.

Treatment

While there is no cure for Parkinson’s disease, treatments can help manage symptoms and improve quality of life:

• Medications – Drugs that help improve movement, walking, and reduce tremors.
• Speech therapy – Working with a speech therapist to address speaking and swallowing difficulties.
• Guided imagery – Using positive mental imagery to reduce stress and influence well-being.
• Physical and occupational therapy – Exercises and therapies to improve balance, flexibility, and mobility.
• Surgical procedures – Options like Gamma Knife treatment or Deep Brain Stimulation (DBS) for advanced cases.
