What Is Parkinson’s Disease?
Parkinson’s disease is a progressive neurological disorder that affects movement, muscle control, and coordination. It occurs due to the gradual loss of dopamine-producing nerve cells in the brain, particularly in an area called the substantia nigra. Dopamine is essential for smooth and controlled muscle movements, and its deficiency leads to the characteristic symptoms of Parkinson’s disease.
Causes of Parkinson’s Disease
-
Degeneration of Dopamine-Producing Brain Cells
The primary cause of Parkinson’s disease is the progressive loss of neurons in the substantia nigra, a region of the brain responsible for producing dopamine. Dopamine plays a vital role in controlling movement, coordination, and muscle tone.
When dopamine levels decrease, communication between the brain and muscles becomes impaired, leading to slow, stiff, and uncontrolled movements.
-
Presence of Lewy Bodies in the Brain
Many people with Parkinson’s disease have abnormal protein deposits called Lewy bodies inside brain cells. These contain a protein known as alpha-synuclein, which interferes with normal brain function and leads to neuronal damage. Lewy bodies are considered a key pathological feature of Parkinson’s disease.
- Genetic Factors and Family History
While most Parkinson’s cases are sporadic, genetic mutations can increase the risk of developing the disease. Certain genes (such as LRRK2, PARK7, PINK1, and SNCA) are associated with inherited forms of Parkinson’s disease. Individuals with a close family member affected by Parkinson’s may have a higher risk.
- Environmental and Toxin Exposure
Long-term exposure to pesticides, herbicides, heavy metals, and industrial chemicals has been linked to an increased risk of Parkinson’s disease. These toxins may damage dopamine-producing neurons and accelerate neurodegeneration.
-
Aging and Oxidative Stress
Age is one of the strongest risk factors. As people age, oxidative stress and mitochondrial dysfunction increase in brain cells, making neurons more vulnerable to damage. This explains why Parkinson’s disease is more common in older adults.
-
Inflammation and Immune System Dysfunction
Chronic inflammation in the brain and abnormal immune responses may contribute to the gradual loss of neurons. Research suggests that immune system dysregulation can play a role in Parkinson’s disease progression.
Symptoms of Parkinson’s Disease
-
Tremors
Tremors are involuntary shaking movements and are often the first noticeable symptom of Parkinson’s disease. They usually begin in one hand or finger and occur when the body part is at rest. Tremors may lessen during movement but can gradually spread to other parts of the body such as the arms, legs, jaw, or lips as the disease progresses.
-
Bradykinesia (Slowness of Movement)
Bradykinesia refers to the slowing down of physical movements, making everyday activities increasingly difficult. Simple tasks such as walking, dressing, writing, or eating take longer to complete. People may struggle to initiate movements, and facial expressions may become reduced, giving a masked or expressionless appearance.
-
Muscle Rigidity
Muscle rigidity causes stiffness in the limbs and trunk, limiting the range of motion. This stiffness can be painful and may affect posture, leading to a stooped appearance. Rigidity makes movements feel tight or robotic and can interfere with smooth and coordinated motion.
-
Balance and Postural Instability
Postural instability affects a person’s ability to maintain balance and remain upright. Individuals with Parkinson’s may feel unsteady while standing or walking and are at a higher risk of falls. This symptom usually appears in the later stages of the disease and can significantly impact mobility and independence.
-
Gait and Walking Difficulties
Parkinson’s disease often changes the way a person walks. Common issues include short, shuffling steps, reduced arm swing, and difficulty turning. Some individuals experience “freezing,” where the feet feel stuck to the ground, especially in narrow spaces or crowded environments.
-
Speech Changes
Speech problems occur due to reduced muscle control affecting the voice and mouth. Speech may become soft, slow, monotone, or slurred, making communication difficult. People with Parkinson’s may also find it hard to start or maintain a conversation.
-
Swallowing Difficulties (Dysphagia)
Swallowing problems arise when the muscles involved in swallowing weaken or become uncoordinated. This can cause drooling, choking, or coughing while eating or drinking. Dysphagia increases the risk of aspiration and chest infections if not managed properly.
-
Cognitive Changes
Parkinson’s disease can affect thinking abilities, leading to slow processing, difficulty concentrating, and memory problems. In advanced stages, some individuals may develop Parkinson’s-related dementia, affecting daily decision-making and independence.
-
Mood and Emotional Changes
Many people with Parkinson’s experience emotional symptoms such as depression, anxiety, irritability, or apathy. These changes are caused by chemical imbalances in the brain and are a direct part of the disease, not simply a reaction to diagnosis.
- Sleep Disorders
Sleep problems are common in Parkinson’s disease and include difficulty falling asleep, frequent waking, vivid dreams, or acting out dreams. Excessive daytime sleepiness and restless legs syndrome may also occur, affecting energy levels and overall health.
-
Autonomic Nervous System Symptoms
Parkinson’s can disrupt automatic body functions controlled by the nervous system. Symptoms may include constipation, low blood pressure when standing, urinary issues, excessive sweating, and sexual dysfunction, all of which can impact daily comfort and quality of life.
-
Sensory Symptoms
Sensory changes such as loss of smell, unexplained pain, tingling sensations, or chronic fatigue can appear early in Parkinson’s disease. A reduced sense of smell is often one of the earliest warning signs before motor symptoms develop.

Advanced Parkinson’s Treatment Approach at Plexus
Aquatic therapy at Plexus uses water-based exercises to help Parkinson’s patients move with greater ease and confidence. The buoyancy of water reduces body weight and joint stress, allowing safer movement while improving balance, coordination, flexibility, and muscle relaxation. This therapy is especially helpful for patients with stiffness, pain, or fear of falls.
Physiotherapy for Parkinson’s disease at Plexus focuses on improving mobility, posture, strength, and balance. Through customized exercise programs, gait training, and fall-prevention strategies, physiotherapy helps reduce rigidity, enhance movement control, and maintain independence in daily activities.
Occupational therapy helps Parkinson’s patients adapt to physical challenges and remain independent in everyday life. At Plexus, therapists work on improving hand coordination, fine motor skills, and functional abilities such as dressing, eating, writing, and personal care, while also recommending assistive tools and home modifications when needed.
Speech therapy at Plexus addresses communication and swallowing difficulties caused by Parkinson’s disease. It helps improve voice strength, speech clarity, breathing control, and swallowing function, reducing risks such as choking and drooling while enhancing overall communication confidence.
Cell therapy at Plexus is an advanced, non-surgical approach that uses the patient’s own autologous cells to support neural repair and reduce inflammation. When combined with rehabilitation therapies, cell therapy aims to enhance neurological function, slow symptom progression, and improve overall functional outcomes in Parkinson’s disease management.
