Parkinsons disease is diagnosed in thousands of Americans every year, making it a common neurological condition. As a progressive disorder, it gradually changes how the brain controls movement, and understanding the condition helps patients make informed decisions about their care. Here is more information on what Parkinsons disease is, what causes it, and the symptoms a patient may experience:
What Is Parkinsons Disease?
Parkinson’s disease is a progressive neurological disorder that affects movement. It develops when nerve cells in a part of the brain called the substantia nigra become damaged or die. These cells produce dopamine, a chemical messenger that helps coordinate smooth, controlled muscle movements. When dopamine levels drop, the brain struggles to regulate movement, and this leads to the characteristic signs of the condition.
The disease typically progresses in stages, with symptoms worsening gradually over many years. Most people receive a diagnosis after the age of 60, but early-onset cases can occur in younger adults. There is no cure at present. Treatment can manage symptoms and support a good quality of life for many years after diagnosis.
What Causes It?
The exact cause of Parkinsons disease remains unknown in most cases, but several factors can raise the risk of developing the condition. Age is the most significant, with the likelihood increasing after 60. A family history of Parkinsons can play a role. Long-term exposure to specific toxins, such as pesticides and herbicides, has the potential to increase risk.
What Are the Symptoms?
Parkinsons disease produces both motor and non-motor symptoms that vary from person to person. Motor symptoms relate to movement and may be the first signs noticed. Non-motor symptoms affect other body systems. Common motor symptoms include:
- Tremor
- Bradykinesia, or slowness of movement
- Muscle stiffness and rigidity
- Balance problems
- Postural instability
Non-motor symptoms include sleep disturbances, loss of smell, constipation, and changes in mood such as depression or anxiety. Some people experience cognitive changes or fatigue as the disease advances.
What Are the Management Options?
Treatment focuses on managing symptoms and maintaining function, since no cure currently exists. A neurologist tailors the approach to each patient, and they assess symptoms, age, and overall health. The two main categories of treatment are medication and surgical intervention.
Medications work by increasing dopamine levels or mimicking its effects in the brain, improving quality of life. Levodopa, often combined with carbidopa, is an effective drug for motor symptoms. Dopamine agonists and other drug classes may be added to manage symptoms or reduce side effects. The response to medication can change over time, necessitating regular dose adjustments under medical supervision.
Deep brain stimulation, or DBS, is a surgical option for patients whose symptoms are no longer well-controlled by medication. The procedure involves implanting electrodes in specific areas of the brain, connected to a small device placed under the skin of the chest. This device sends electrical signals that help regulate abnormal brain activity and reduce tremor, stiffness, and slowness. DBS does not cure the disease, but it can improve symptoms and reduce reliance on medication for suitable candidates.
Learn More From a Specialist
Parkinsons disease is a progressive neurological condition caused by the loss of dopamine-producing brain cells, and it produces a mix of motor symptoms, such as tremor and stiffness, and non-motor symptoms, such as sleep and mood changes. While the condition cannot be cured, medications and deep brain stimulation offer effective ways to manage symptoms and support daily life. Book a consultation with a neurology specialist to discuss your symptoms and explore the management options that suit your needs.
