Parkinson's Disease

Overview

Parkinson's Disease is a progressive condition that primarily affects the nervous system and the parts of the body controlled by nerves. It develops gradually, often starting with a barely noticeable tremor in just one hand. While tremors are the most well-known sign, the disorder also commonly causes stiffness, slowing of movement, and balance issues. In India, as our population ages, we are seeing a significant rise in Parkinson's cases, particularly among those over the age of 60. It occurs because certain nerve cells in the brain responsible for producing dopamine—a chemical messenger that coordinates smooth muscle movement—begin to break down or die. While it is a long-term condition, it is important to remember that it is highly manageable. With the right medical guidance, specialized exercises, and a supportive healthcare team at Sanjeevi Hospital, most patients continue to lead active, fulfilling, and independent lives for many years after their diagnosis.

Symptoms to watch for

• Resting tremors: Shaking that usually begins in a limb, often your hand or fingers, especially when at rest.
• Slowed movement (Bradykinesia): Over time, simple tasks may become difficult and time-consuming, and your steps may become shorter when you walk.
• Rigid muscles: Muscle stiffness may occur in any part of your body, which can be painful and limit your range of motion.
• Impaired posture and balance: Your posture may become stooped, or you may experience falls or balance problems.
• Loss of automatic movements: You might have a decreased ability to perform unconscious movements, like blinking or swinging your arms when you walk.
• Speech changes: You may speak softly, quickly, or hesitate before talking, often with a more monotone expression.
• Writing changes: It may become hard to write, and your handwriting may appear much smaller than usual.
• Fixed facial expression: The face may appear less expressive or 'mask-like' even when you are feeling strong emotions.
• Sleep disturbances: Frequent waking, restless legs, or acting out dreams during the night.

Causes & risk factors

• Dopamine depletion: The primary cause is the loss of neurons that produce dopamine in a specific part of the brain.
• Genetic factors: Specific genetic mutations can increase risk, although this is less common unless many family members are affected.
• Environmental triggers: Exposure to certain toxins, pesticides, or well water in rural farming areas may slightly increase long-term risk.
• The presence of Lewy bodies: Clumps of specific substances within brain cells are microscopic markers of Parkinson's disease.
• Alpha-synuclein protein: A protein found within Lewy bodies that researchers believe plays a key role in the progression of the condition.
• Age: The risk increases significantly as you get older, typically starting around age 60 or older.
• Gender: Men are statistically more likely to develop Parkinson's disease than women.
• Head injuries: Some studies suggest that repetitive or severe head trauma might be a contributing risk factor.

Diagnosis

• Clinical Neurological Exam: A thorough review of your symptoms and a physical exam by our specialist to check coordination and walking.
• Dopamine Transporter Scan (DaTscan): A specialized imaging test that helps visualize the dopamine system in the brain.
• Medical History Review: Discussing your long-term symptoms, lifestyle, and family health history in detail.
• Response to Medication: Sometimes, the doctor will see if your symptoms improve significantly with specific Parkinson’s medications to confirm the diagnosis.
• MRI or CT Scan: While these don't 'see' Parkinson's, they help rule out other conditions like strokes or brain tumors.
• Blood Tests: Used to check for other metabolic issues or vitamin deficiencies that might mimic movement disorders.
• Walking and Balance Assessment: Observing your gait and 'pull test' to check how well you recover your balance.

Treatment options

Prevention & self-care

• Regular aerobic exercise: Activities like walking, swimming, or cycling can help keep the brain and body healthy.
• Healthy diet: Focus on antioxidant-rich foods like colorful vegetables, fruits, and green tea which may support brain health.
• Stay mentally active: Engaging in puzzles, reading, and social activities helps maintain cognitive function.
• Avoid toxins: Minimize exposure to pesticides and herbicides commonly used in agricultural settings whenever possible.
• Vitamin D: Maintain healthy levels of Vitamin D, as some studies suggest a link between deficiency and neurological health.
• Adequate sleep: Ensuring 7-8 hours of quality sleep helps the brain clear out metabolic waste.
• Hydration: Drink plenty of water throughout the day to support overall cellular health and digestion.
• Yoga and Tai Chi: These traditional practices are excellent for maintaining balance, flexibility, and peace of mind.
