Understanding Parkinson’s Disease

Parkinson’s disease (PD) is a progressive neurological disorder that primarily affects movement. It develops gradually, sometimes starting with a barely noticeable tremor in just one hand. While tremors are common, the disorder also commonly causes stiffness or slowing of movement. In the early stages of Parkinson’s disease, the face may show little or no expression, or arms may not swing when walking. Speech can also become soft or slurred, and the individual’s posture may change. Parkinson’s disease symptoms worsen as the condition progresses over time.

Understanding Parkinson’s Disease

Parkinson’s disease is caused by the degeneration of neurons in a part of the brain called the substantia nigra. These neurons produce dopamine, a neurotransmitter that plays a crucial role in regulating the movement of the body. The reduction in dopamine levels leads to the symptoms of Parkinson’s disease. The exact cause of this neuronal degeneration is unknown, although a combination of genetic and environmental factors is believed to play a role.

Symptoms of Parkinson’s Disease

Symptoms and their severity vary from person to person but typically include:

  • Tremors or shaking
  • Slowness of movement (bradykinesia)
  • Rigidity or stiffness of the limbs and trunk
  • Impaired balance and coordination, leading to falls
  • Non-motor symptoms can also occur, such as sleep disturbances, depression, anxiety, and cognitive changes.

Therapies for Parkinson’s Disease

There is currently no cure for Parkinson’s disease, but there are several therapies that can help control the symptoms:


  • Levodopa: The most effective Parkinson’s disease medication is levodopa, which is converted into dopamine in the brain. However, as the disease progresses, the benefits of levodopa may become less consistent.
  • Dopamine Agonists: These mimic the effects of dopamine in the brain and can be used alone or with levodopa.
  • MAO-B Inhibitors: These help prevent the breakdown of brain dopamine by inhibiting the enzyme monoamine oxidase B (MAO B).
  • Anticholinergics: These are used to help control the tremor associated with Parkinson’s disease.
  • Amantadine: Can provide short-term relief of symptoms in the early stages.

Surgical Treatments

  • Deep Brain Stimulation (DBS): Surgical procedure that involves implanting electrodes in certain areas of the brain. These electrodes produce electrical impulses that regulate abnormal impulses. DBS is most often offered to individuals whose symptoms cannot be adequately controlled by medications.

Lifestyle Modifications and Other Therapies

  • Physical Therapy: Helps with mobility, flexibility, and balance.
  • Occupational Therapy: Assists in adapting to living with Parkinson’s disease, focusing on improving the ability to perform daily activities.
  • Speech Therapy: Helps manage problems with speaking and swallowing.
  • Exercise: Regular exercise can improve mobility and balance. It can also have a positive effect on mood and mental health.


While Parkinson’s disease is a challenging condition with a progressive nature, advancements in treatment and management strategies offer hope and improve the quality of life for those affected. Early diagnosis and tailored treatment plans, combining medication, surgical options, and supportive therapies, can help manage symptoms effectively. Ongoing research continues to explore new treatment avenues, including stem cell therapies and gene therapy, which may offer further hope for the future. Living with Parkinson’s disease requires adjustments and coping strategies, but with the right support and treatment, many people lead full, active lives.
