EN-B-NS-CN2301-V51_20260105_145552_v1

Introduction

Parkinson’s disease is a long-term brain disorder. It mainly affects movement and can change daily life. According to the World Health Organization (WHO), millions of people worldwide live with Parkinson’s disease. Early signs may be mild, but symptoms often get worse over time. Because it can impact walking, talking, and daily tasks, understanding Parkinson’s disease is important for patients and families.

Symptoms of Parkinson’s Disease

Parkinson’s disease symptoms can start slowly. At first, they may be hard to notice. However, as the disease progresses, symptoms become more obvious. Recognizing early and advanced signs helps with early care.

Early Symptoms

  • Tremor or shaking, often in the hands or fingers
  • Stiffness in arms or legs
  • Slow movement (bradykinesia)
  • Trouble with balance or walking
  • Small, cramped handwriting
  • Soft or low voice

    • Advanced Symptoms

  • Difficulty standing or walking
  • Freezing, or feeling stuck in place
  • Problems with memory or thinking
  • Changes in mood, such as depression
  • Trouble swallowing or speaking clearly

    • Because symptoms can vary, not everyone will have the same signs. Yet, if you notice these changes, it is wise to see a doctor.

    Causes and Risk Factors

    Doctors do not know the exact cause of Parkinson’s disease. However, it happens when brain cells that make dopamine die or stop working. Dopamine is a chemical that helps control movement. While the cause is unclear, several risk factors increase the chance of developing Parkinson’s disease.

  • Age: Most people develop it after age 60.
  • Family history: Having a close relative with Parkinson’s raises your risk.
  • Gender: Men are more likely to get Parkinson’s than women.
  • Exposure to toxins: Long-term contact with pesticides or chemicals may increase risk.

    • Although these factors play a role, many people with Parkinson’s disease have no clear risk factors.

    Diagnosis: How Is Parkinson’s Diagnosed?

    There is no single test for Parkinson’s disease. Instead, doctors use a mix of exams and questions. Early diagnosis helps with better care and planning. So, if you notice symptoms, see a neurologist soon.

  • Medical history: The doctor asks about symptoms and family history.
  • Physical exam: The doctor checks movement, balance, and reflexes.
  • Imaging tests: MRI or CT scans rule out other problems, but they do not confirm Parkinson’s.
  • Response to medication: Sometimes, doctors give Parkinson’s medicine to see if symptoms improve.

    • Because symptoms can look like other diseases, a specialist may use special criteria to confirm the diagnosis. The Centers for Disease Control and Prevention (CDC) and medical journals support these steps.

    Treatment Options for Parkinson’s Disease

    While there is no cure for Parkinson’s disease, many treatment options help manage symptoms. Early treatment can improve quality of life. Your doctor will suggest a plan based on your needs.

    Medications

  • Levodopa: This is the most common drug. It helps replace lost dopamine.
  • Dopamine agonists: These drugs act like dopamine in the brain.
  • MAO-B inhibitors: These help prevent dopamine breakdown.

    • Surgery

  • Deep brain stimulation (DBS): Doctors place electrodes in the brain to help control movement.

    • Therapies

  • Physical therapy: Improves strength and balance.
  • Speech therapy: Helps with talking and swallowing.
  • Occupational therapy: Teaches ways to do daily tasks more easily.

    • Because each person is different, your doctor may adjust treatment over time. For more details, visit the WHO or CDC websites.

    Lifestyle Tips for Managing Parkinson’s

    Besides medical care, healthy habits can help manage Parkinson’s disease symptoms. Even small changes can make a big difference.

  • Exercise regularly to keep muscles strong and flexible
  • Eat a balanced diet with fruits, vegetables, and whole grains
  • Get enough sleep each night
  • Join a support group for emotional help
  • Use safety aids, like handrails, to prevent falls
  • Keep a routine to help with memory and daily tasks

    • Because Parkinson’s disease can be stressful, caring for your mental health is also important.

    Prevention and Outlook

    Currently, there is no sure way to prevent Parkinson’s disease. However, some studies suggest regular exercise and a healthy diet may lower risk. Although Parkinson’s disease is a lifelong condition, many people live active lives for years. With early diagnosis and the right treatment options, symptoms can be managed well. Ongoing research gives hope for better treatments in the future.

    If you or a loved one notice signs of Parkinson’s disease, consult a neurologist for personalized advice on Parkinson’s disease.
