What Is Parkinson's Disease? Symptoms, Causes and Treatment Methods

What Is Parkinson's Disease?

Parkinson's disease is a slowly progressive nervous system disorder that occurs when dopamine levels decrease in brain regions involved in movement control. It is usually seen in people over 60, but it can also begin at younger ages.

The disease is not limited to tremor. It may cause slowed movement, muscle stiffness, posture and balance problems, reduced facial expression, smaller handwriting and changes in walking. Some patients may also experience non-motor symptoms such as constipation, sleep problems, reduced sense of smell, mood changes and cognitive difficulties.

What Are the Symptoms of Parkinson's Disease?

Although hand tremor is one of the best-known symptoms, Parkinson's disease is not limited to tremor. It may present with slowed movement, muscle stiffness, balance problems and reduced facial expression.

• Tremor: Rhythmic shaking, especially in the hands, often seen at rest.
• Bradykinesia: Slowed movement and difficulty with daily tasks.
• Rigidity: Stiffness in the arms, legs, neck or trunk.
• Posture and balance problems: Stooped posture, increased risk of falls and gait changes.
• Non-motor symptoms: Constipation, sleep problems, reduced sense of smell, depression, anxiety and attention-memory problems.

Parkinson's disease may progress over time. Although it cannot be completely eliminated with treatment, symptoms can often be managed and quality of life can be supported.

What Is Tremor? What Are the Differences Between Parkinson's and Tremor?

“Is your hand shaking and are you worried about Parkinson's disease? Not every tremor means Parkinson's disease.” Tremor is an involuntary and rhythmic movement in a body part.

Tremor in Parkinson's disease is usually called a resting tremor. It may become more noticeable when the hand is not being used and may decrease during movement. In other tremor types, such as essential tremor, shaking may increase during writing, holding a glass or maintaining a posture.

Tremor may also be caused by thyroid disease, certain medications, caffeine, stress, essential tremor and other neurological conditions. Persistent or worsening tremor should be evaluated by a neurologist.

What Causes Parkinson's Disease?

The exact cause of Parkinson's disease is not fully known, but loss of dopamine-producing nerve cells is one of the main mechanisms. Genetic predisposition, age, male sex and exposure to certain environmental toxins or pesticides may be associated with increased risk.

Parkinson's disease does not have a single cause. It is a complex condition in which genetic and environmental factors may act together. Risk may be higher with family history, but many patients do not have a clear family history.

How Is Parkinson's Disease Diagnosed?

There is no single specific laboratory test that definitively diagnoses Parkinson's disease. Diagnosis is usually based on symptoms, medical history, medication history, neurological examination and clinical course over time.

The neurologist evaluates slowed movement, resting tremor, rigidity, posture, gait and balance findings. In some patients, brain imaging, blood tests or dopamine transporter imaging may be used to rule out other conditions or support the clinical diagnosis.

Can Parkinson's Disease Be Treated?

There is no definitive cure that completely eliminates Parkinson's disease; however, symptoms can often be controlled. The goal of treatment is to improve mobility, daily functioning, independence and quality of life.

The treatment plan is personalized according to age, symptom severity, impact on daily life, coexisting diseases, medication side effects and disease stage.

What Are the Treatment Methods?

1. Medication: Medicines that replace dopamine or mimic its effects are among the main approaches for symptom control. Dose and timing should be adjusted by a neurologist.
2. Physical therapy and rehabilitation: These may help improve mobility, balance, fall prevention and daily activities.
3. Surgery: Deep brain stimulation (DBS) may be considered in selected patients with medication-resistant tremor, motor fluctuations or medication-related involuntary movements.
4. Nutrition and lifestyle: Regular exercise, balanced nutrition, adequate fluids and fiber, sleep regulation, fall-prevention home arrangements and social support complete the treatment plan.

Recommendations for People With Parkinson's Disease

One of the most important habits recommended for people with Parkinson's disease is regular exercise. Exercise may improve mobility, reduce stiffness, support balance and make daily life safer. Walking, stretching, balance exercises and individualized programs supervised by a physiotherapist may be helpful.

Balanced nutrition, adequate fluid intake, fiber-rich foods and measures to reduce constipation are important. Taking medication regularly and at the correct time, maintaining sleep routines, reducing stress, seeking early support for speech or swallowing problems and staying socially connected can help disease management.
