Introduction to Parkinson's Disease

Parkinson's disease is a neurological disorder that affects approximately one million people in the United States. It is caused by damage to the brain cells that produce dopamine, a chemical responsible for controlling muscle movement and coordination. People with Parkinson's often experience a variety of motor symptoms, including tremors, stiffness, and difficulty walking. In addition to physical challenges, Parkinson's can also cause mental health issues such as depression, anxiety, and even dementia. The purpose of this guide is to provide an overview of Parkinson's disease, explain how it can be diagnosed, and outline available treatment options.

Overview of Parkinson's Disease

Parkinson’s disease is a chronic, degenerative neurological disorder that affects movement, muscle control and coordination. It is caused by a gradual loss of nerve cells in the brain, which occurs when a person has insufficient dopamine production. Dopamine is a neurotransmitter that helps with communication between the brain and various muscles and organs throughout the body.

Who is most affected? Parkinson’s disease can affect people of any age. However, it is most often diagnosed in people over the age of 50. People of all races and ethnic backgrounds are equally affected by the disease. Men are more likely to be diagnosed with Parkinson’s than women.

Although researchers still don’t fully understand what causes Parkinson’s disease, there is evidence that genetics and environmental factors may play a role in its development.

What Are the Symptoms of Parkinson’s Disease?

Parkinson’s disease is a progressive neurological disorder that affects a person’s ability to control movement. It is characterized by several physical and cognitive symptoms which can vary from one person to another. The most common symptoms of Parkinson’s disease include tremor, rigidity, instability, slow movement, and impaired responses.


One of the earliest symptoms of Parkinson’s disease is a tremor or trembling in the hands, legs, or chin. The tremor usually begins on one side of the body and is most noticeable when the hand is at rest. It may increase in intensity when the person is under stress or emotional duress.


Rigidity or stiffness of the body or limbs is often associated with Parkinson’s disease. This symptom usually begins in the shoulder and neck area and can spread to other parts of the body over time. People with rigidity may feel stiff, especially when starting to move.


Instability or difficulty maintaining balance is often a sign of the disease. People with Parkinson’s disease may experience falls or difficulty walking. In some cases, extreme instability may cause an individual to walk in a bent-over position, making it difficult for them to walk without assistance.

Slow Movement

People with Parkinson’s disease may experience a decrease in their overall speed of movement. This symptom is called bradykinesia and may cause individuals to have a shuffling gait, drooping eyelids, and a mask-like facial expression. Furthermore, the individual’s movements may become delayed or interrupted.

Impaired Responses

Impaired responses or difficulty responding to stimuli are common symptoms of Parkinson’s disease. People may have difficulty speaking or thinking quickly. They may also experience changes in their ability to think and reason, and may struggle to complete tasks.

Tracking Symptoms of Parkinson’s Disease

For those living with Parkinson’s disease it is important to keep track of any changes in their symptoms. Doing so can help them be better informed and give the healthcare team a comprehensive understanding of the progression of the disease over time. Tracking symptoms can lead to more timely diagnosis, improved treatment outcomes, and provide patients with a greater sense of control over their health and care.

By tracking symptoms over time, patients can make their healthcare team aware of any shifts in their condition and enable them to adjust medications or other treatments, as needed. Similarly, keeping accurate records can assist in the diagnosis of Parkinson’s disease. By providing detailed information on the progression and nature of their symptoms, physicians can more accurately identify Parkinson’s disease and rule out other conditions.

In order to properly track and monitor symptoms, patients should keep a record of all their symptoms, medication dosages, and medical visits, as well as any changes to their overall health and wellbeing. Symptoms to keep track of include tremors, muscle rigidity, slowness of movement, balance issues, and any emotional or cognitive side effects of the condition.

Patients may wish to keep a journal in which they can regularly document changes to their symptoms. This should include notes on sleep patterns, physical activity levels, mood fluctuation, medication effectiveness, and any recurrences of symptoms. Patients can also use specific symptom tracking apps to document and analyze any changes. Doing so will make it easier for them to recognize any patterns in their symptoms and aid in more timely diagnosis and effective management of their condition.

Risk Factors

Parkinson’s disease affects millions of people around the world, and it can be a difficult condition to live with. While it’s not always possible to prevent Parkinson’s disease, it is important to understand the risk factors associated with an increased likelihood of developing the condition.

There are a few key risk factors associated with Parkinson’s disease, including family history, environmental exposures, and age. People with a family history of Parkinson’s disease are more likely to develop the condition. Additionally, certain environmental exposures have been linked to increased risk of Parkinson’s disease. Long-term exposure to hazardous chemicals or toxins can increase the likelihood of developing the condition. Finally, age is a major risk factor for Parkinson’s disease, as it becomes more common with age.

These risk factors can contribute to an increased likelihood of developing Parkinson’s disease, but it’s important to remember that it is still possible to develop the condition without any of these risk factors. If you have questions about your risk of Parkinson’s disease, you should speak with your doctor.

Diagnosis of Parkinson's Disease

Parkinson's disease is a chronic neurological disorder which affects movement, often involving tremor, stiffness, and coordination difficulties. In order to properly diagnose this condition, doctors must go through a process of medical evaluations and imaging studies.

The most important part of diagnosing Parkinson's disease is the physical examination and medical history. During the physical exam, the doctor may ask questions about the patient's medical history, as well as perform a neurological examination to check for signs and symptoms of the disease. They may use tools such as a penlight or tuning fork to examine the patient. The doctor may also order blood tests, urine tests, or an electroencephalogram (EEG) to rule out other medical conditions.

Imaging studies are also helpful in diagnosing Parkinson's disease. Brain scans such as magnetic resonance imaging (MRI) or computed tomography (CT) scans can help the doctor identify any structural changes occurring in the brain. Positron emission tomography (PET) scans may also be used to measure how well the patient’s brain cells are functioning.

In some cases, dopamine transporter (DaT) scans may be used to detect abnormally low levels of dopamine in the brain, which is a common sign of Parkinson's disease. This scan can also help distinguish between different types of Parkinson's disease.

These tests can help the doctor make a diagnosis, however they are not always conclusive. In many cases, additional tests may be required to confirm the diagnosis. The patient’s response to medication may also be taken into consideration before a diagnosis is made.

Treatment Options for Parkinson's Disease

When it comes to Parkinson’s disease, there is no one-size-fits-all treatment. Instead, many different approaches can be used and tailored to the individual needs of the patient. The main categories of treatment options for Parkinson’s disease are medication, therapies, and lifestyle changes.


Drug therapy is one of the most common treatments for Parkinson’s disease, and is usually the first approach taken. Medications, such as levodopa (L-dopa), dopaminergic agonists, and monoamine oxidase inhibitors, are used to increase the level of dopamine in the brain - a chemical that declines in those with Parkinson’s disease. These drugs can help manage the symptoms of Parkinson’s disease, including tremor, stiffness, instability, and slowness of movement.


Physical therapy is a useful tool for increasing mobility, balance, and strength. Speech therapy can help individuals maintain their voice and manage speech difficulties associated with Parkinson’s. Occupational therapy assists with day-to-day activities such as eating and keeping a home. Psychotherapy can help individuals and their families learn to cope with the emotional aspects of living with a chronic illness.

Lifestyle Changes

There are various lifestyle changes that can help with the management of Parkinson’s disease. Eating a healthy diet with plenty of vitamins and minerals can give the body an energy boost and help keep joints lubricated. Regular exercise can help keep muscles strong and flexible. In addition, setting and keeping up routines and being mindful of stress levels can help reduce symptoms.

Overall, when it comes to treating Parkinson’s disease, there is no right or wrong approach - it depends on the individual patient and what works best for them. It is important to discuss treatment options with your doctor and explore which ones might be most beneficial for you.
