Understanding Parkinson’s: A Disease That Causes Shaking and Tremors

Parkinson’s disease is a debilitating disorder that affects millions of people worldwide. It is a progressive neurodegenerative disorder that affects movement and is characterized by tremors, stiffness, and loss of balance. In this article, we will be taking a deep dive into Parkinson’s disease, its symptoms, causes, treatment, and more.

What is Parkinson’s disease, and what causes it?

Parkinson’s disease is a disorder of the nervous system that affects movement. It develops when cells in a part of the brain called the substantia nigra start to die. These cells produce dopamine, a chemical messenger that helps control movement. As dopamine levels drop, the symptoms of Parkinson’s disease progressively worsen.

The exact cause of Parkinson’s disease is not known. However, researchers have suggested that both genetic and environmental factors may play a role in the development of the disease. Environmental factors suspected to be linked with Parkinson’s disease include exposure to pesticides, herbicides, and other toxins.

What are the symptoms of Parkinson’s disease?

Parkinson’s disease symptoms can vary from individual to individual. However, the most common symptom is tremors or shaking. These tremors usually start in one hand and can gradually spread to other parts of the body. Other symptoms may include:

– Stiffness in the limbs or trunk
– Slow movement
– Problems with balance and coordination
– Involuntary movements
– Speech difficulties
– Changes in writing ability

How is Parkinson’s disease diagnosed and treated?

There is no specific test to diagnose Parkinson’s disease. However, a neurologist can usually diagnose Parkinson’s disease based on a person’s symptoms, medical history, and a physical examination. Brain scans and other tests may also be necessary to rule out other conditions that may have similar symptoms.

Currently, there is no cure for Parkinson’s disease. Treatment is focused on managing symptoms using medication, therapy, and surgical interventions as needed. Medications such as levodopa, carbidopa-levodopa, dopamine agonists, and MAO-B inhibitors can help relieve symptoms.

Physical therapy and exercise can also help improve balance and coordination. Additionally, in some cases, surgery may be recommended to implant a deep brain stimulator that can help regulate movement.


Parkinson’s disease is a devastating disorder that affects millions of people worldwide. While there is no cure for Parkinson’s disease, early diagnosis and treatment can help manage symptoms and improve the quality of life for those living with the disease. By understanding Parkinson’s and its symptoms, we can work to improve the lives of those living with this condition.
