A Guide to Parkinson’s Disease and Clinical Trials
Parkinson’s disease is a neurogenerative disorder that primarily affects older people (ages 50+) but can also occur in younger adults. This chronic disease significantly impacts a person’s motor system, triggering a wide range of symptoms related to movement and coordination.
The first signs of Parkinson’s are often subtle such as feelings of weakness or stiffness, a trembling hand, or difficulty with balance. Eventually, these symptoms will worsen and spread as other side effects appear.
Over the progression of the disease, depression, cognitive issues, and other mental or emotional problems become increasingly likely.
There is currently no cure for Parkinson’s disease. Fortunately, there are treatments available to help prevent, minimize, and/or mitigate the side effects of the condition.
What Causes Parkinson’s Disease?
Researchers have been unable to pinpoint a precise cause of Parkinson’s disease. This is a complex neurodegenerative disorder, and as such, has many factors involved in its origin and progression.
Today, most scientists and doctors believe Parkinson’s disease is likely caused by a combination of genetic and environmental factors. Some key factors associated with Parkinson’s include:
Most Parkinson’s cases occur without a clear genetic cause – but a small percentage of cases (around 5-10%) are thought to be triggered by genetic mutations. These mutations can be inherited from one or both parents and may lead to the disease’s early onset, usually before the age of 50.
In addition to rare mutations, there are genetic risk factors that can increase a person’s chances of developing Parkinson’s. These factors do not guarantee the person will develop the disease, but they do increase the likelihood.
Some evidence suggests that exposure to certain toxins or chemicals may increase the risk of developing Parkinson’s disease. These can include pesticides, herbicides, heavy metals, and other industrial chemicals.
Abnormal protein deposits (Lewy bodies) can build up in brain cells. These aggregates are known to disrupt the normal functioning of nerve cells and are therefore thought to contribute to the neurodegeneration seen in Parkinson’s.
Inflammation and Immune System Involvement
Inflammation and the immune system’s response may play a role in the development and progression of Parkinson’s disease. Some studies found that the immune system mistakenly targeted and attacked healthy brain cells in Parkinson’s disease, resulting in neuronal damage.
While all of these factors have been implicated in Parkinson’s, none of them fully explain all cases of the disease. That’s why continual research on Parkinson’s and its development is critical in our understanding and treatment of the condition.
Who Develops Parkinson’s Disease?
Parkinson’s disease can affect individuals of all genders, ages, and ethnicities, but it is most common in people over the age of 60. However, some research indicates that Parkinson’s disease could be becoming more prevalent in younger adults.
Additionally, studies suggest that men may be twice as likely to develop Parkinson’s as women – but women have a higher mortality rate and faster disease progression.
How Common Is Parkinson’s Disease?
Parkinson’s is one of the most commonly observed neurodegenerative disorders, second only to Alzheimer’s disease. In America, it’s estimated that over 90,000 people are diagnosed with Parkinson’s annually – and many other individuals with the disease may be undiagnosed or misdiagnosed.
As the global population continues to age, the prevalence of Parkinson’s disease is expected to rise. This further highlights the cruciality of ongoing research and efforts to develop effective treatments.
Symptoms of Parkinson’s Disease
Parkinson’s disease is characterized by a range of motor and non-motor symptoms. These can vary in severity and progression from person to person. Some of the most common symptoms include:
Note: not everyone with Parkinson’s disease will experience all of these symptoms, and the progression of the disease tends to vary widely among individuals.
Regardless, early diagnosis and management are critical in improving the quality of life for those with Parkinson’s. If you or someone you know is experiencing these symptoms, seek medical guidance from a healthcare professional as soon as possible.

How Parkinson’s Disease Is Diagnosed
1. Review Medical History
Most healthcare professionals will start by asking detailed questions about the patient’s medical background, including their family history, type of employment, lifestyle habits, etc. This helps them assess the likelihood of Parkinson’s presence.
2. Physical Examination
Next, the healthcare provider will perform a neurological examination to assess the patient’s motor skills, reflexes, balance, coordination, and muscle tone. They will also look for physical signs of Parkinson’s, including resting tremors, bradykinesia, and muscle rigidity.
Fortunately, many people with Parkinson’s respond positively to medications. Once a diagnosis has been made, the healthcare provider will determine which medications may help with symptom alleviation and slow the disease’s progression.
4. Brain Imaging
Although not always necessary, the healthcare provider may order brain imaging (such as MRI or CT scans) to rule out other structural abnormalities in the brain.
5. Specialist Consultation
If Parkinson’s disease has been diagnosed, the patient may be referred to a neurologist or movement disorder specialist for a more in-depth evaluation and confirmation.
Potential Treatments for Parkinson’s Disease
There is currently no set treatment or “cure” for Parkinson’s disease. In most cases, prescribed treatment methods aim to alleviate the symptoms or slow the disease’s progression, but they cannot reverse the diagnosis.
Parkinson’s treatment plans are tailored to each patient based on the severity of their symptoms and other individual factors. Some common treatments for Parkinson’s disease include:
Deep Brain Stimulation
This is a surgical procedure that involves implanting electrodes in specific areas of the brain and connecting them to a pulse generator. Most commonly, deep brain stimulation is thought to help with motor-related symptoms of Parkinson’s, but it may also help with sleep problems and pain.
Physical Therapy and Exercise
Regularly attending physical therapy and exercising can help Parkinson’s patients improve their mobility, balance, and flexibility. There are many powerful ways to get active with this disorder, including biking, running, yoga, pilates, and weight training.
Speech Therapy and Occupational Therapy
Despite the strong evidence supporting the efficacy of this treatment, only about 14% of Parkinson’s patients include it in their treatment plan. Still, healthcare providers are increasingly recommending speech and occupational therapy to help slow the disease’s progression, assist with movement problems, and improve daily functioning.
Diet and Nutrition
Some studies suggest that a well-balanced, nutritious diet (perhaps Mediterranean) may benefit individuals with Parkinson’s. Including a variety of whole grains, fruits, vegetables, and protein-rich foods may ease some common Parkinson’s symptoms.
Note: recommended treatments vary from person to person, and the management of Parkinson’s requires ongoing adjustments and monitoring by healthcare professionals.
New treatments and research are continually emerging, so patients with Parkinson’s will need to work closely with their healthcare team to ensure they are receiving the best possible care.

How to Support Others With Parkinson’s Disease
Living with or supporting someone with Parkinson’s disease isn’t always a straightforward path. As a friend or family member, you may need to offer emotional, practical, and social assistance to help improve your loved one’s quality of life.
Here are some ways you can support and care for someone with Parkinson’s disease:
First things first: learn about Parkinson’s from reputable websites and other resources. Familiarize yourself with the symptoms, treatment options, and challenges associated with the disease. Not only will this help you better understand your loved one’s experience, but it will also help you offer accurate, productive support and advice.
Assist with Medical Appointments
People with Parkinson’s may struggle to manage appointments and get themselves to doctor’s offices. One way you can help is by offering to accompany them to appointments or therapy sessions if needed. You may also want to take notes during the appointments, as it can be challenging for a person with Parkinson’s to remember all the details.
Offer Emotional Support
As we mentioned earlier, many people with Parkinson’s struggle with anxiety, depression, and a feeling of hopelessness. Sometimes, the best thing you can do to support your loved one is simply to acknowledge their emotions and validate their feelings. Be there when they need a listening ear.
Help With Daily Activities
People with Parkinson’s disease may struggle with a range of daily activities – dressing, eating, drinking, managing medications, bathing, driving, etc. The more you can assist with these everyday tasks, the more independence your loved one can maintain.
Maintaining an upbeat outlook on Parkinson’s isn’t easy – there’s no cure, and the disease progresses over time. However, staying positive is one of the most supportive things you can do for your loved one.
Focus on celebrating each and every achievement, no matter how small. Find moments to laugh together and encourage social interactions, especially with other positive friends and family members.
Of course, everyone’s experience with Parkinson’s is different. Be sure to directly ask your loved one how you can best support them. Sometimes, a shoulder to lean on is the best form of care you can offer.
