Parkinson’s disease (PD) is a chronic and progressive movement disorder, meaning that symptoms continue and worsen over time. Nearly one million people in the US are living with Parkinson’s disease. The cause is unknown, and although there is presently no cure, there are treatment options such as medication and surgery to manage its symptoms.
Parkinson’s involves the malfunction and death of vital nerve cells in the brain, called neurons. Parkinson’s primarily affects neurons in an area of the brain called the substantia nigra. Some of these dying neurons produce dopamine, a chemical that sends messages to the part of the brain that controls movement and coordination. As Parkinson’s Disease progresses, the amount of dopamine produced in the brain decreases, leaving a person unable to control movement normally
Causes of Parkinson’s Disease
Parkinson’s disease is caused by a loss of nerve cells in part of the brain called the substantia nigra. This leads to a reduction in a chemical called dopamine in the brain. Dopamine plays a vital role in regulating the movement of the body. A reduction in dopamine is responsible for many of the symptoms of Parkinson’s disease. Exactly what causes the loss of nerve cells is unclear. Most experts think that a combination of genetic and environmental factors is responsible.

Parkinson’s disease affects the nerve cells in the brain that produce dopamine. Parkinson’s disease symptoms include muscle rigidity, tremors, and changes in speech and gait. After diagnosis, treatments can help relieve symptoms, but there is no cure.
What Are the Symptoms of Parkinson’s Disease?
Symptoms of Parkinson’s disease differ from person to person. They also change as the disease progresses. Symptoms that one person gets in the early stages of the disease, another person may not get until later-or not at all. Symptoms typically begin appearing between the ages of 50 and 60. They develop slowly and often go unnoticed by family, friends, and even the person who has them.
What is the prognosis?
Parkinson’s Disease is both chronic, meaning it persists over a long period of time, and progressive, meaning its symptoms grow worse over time. Although some people become severely disabled, others experience only minor motor disruptions. Tremor is the major symptom for some individuals, while for others tremor is only a minor complaint and other symptoms are more troublesome. It is currently not possible to predict which symptoms will affect an individual, and the intensity of the symptoms also varies from person to person.
Treating Parkinson’s disease
Although there’s currently no cure for Parkinson’s disease, treatments are available to help reduce the main symptoms and maintain quality of life for as long as possible.
Supportive treatments – such as physiotherapy and occupational therapy
In some cases, brain surgery
