What Is Parkinson’s Disease
Parkinsons disease is movement disorder of the nervous system that worsens over time. As nerve cells in parts of the brain weaken or are damaged or die, people may begin to notice problems with movement, tremor, stiffness in the limbs or the trunk of the body, or impaired balance. As these symptoms become more obvious, people may have difficulty walking, talking, or completing other simple tasks. Not everyone with one or more of these symptoms has PD, as the symptoms appear in other diseases as well.
No cure for PD exists today, but research is ongoing and medications or surgery can often provide substantial improvement with motor symptoms.
Connections Between Parkinsons And Dementias
The average life expectancy for people with Parkinsons has increased. So we have seen more cases where the progression of the disease leads to cognitive impairment or dementia. Understanding the connection between the motor symptoms and neurodegenerative properties of the disease is a crucial next step in research. That may be the biggest unmet need right now, says Dr. Stern, Therapies to prevent that from occurring.
Those cognitive issues also highlight the similarities or connections between Parkinsons disease dementia and other dementias. Theres a spectrum between Alzheimers disease and Parkinsons dementia, and often the pathologies coexist, Dr. Stern says. In many instances, we find the changes of Alzheimers disease in Parkinsonian brains. This overlap makes it difficult to make an accurate diagnosis while a person is alivebut it also means a breakthrough for one disease could lead to a breakthrough for the other.
New research is exploring how to better distinguish between these degenerative brain diseases. One area of study focuses on the ability to pick up very small amounts of alpha-synuclein in the blood or spinal fluid. While this type of testing is not ready for clinical use yet, Dr. Stern says it may be available soon.

What Are The Symptoms Of The Disease
The four primary symptoms of PD are:
- Tremor. Tremor often begins in a hand, although sometimes a foot or the jaw is affected first. The tremor associated with PD has a characteristic rhythmic back-and-forth motion that may involve the thumb and forefinger and appear as a pill rolling. It is most obvious when the hand is at rest or when a person is under stress. This tremor usually disappears during sleep or improves with a purposeful, intended movement.
- Rigidity. Rigidity , or a resistance to movement, affects most people with PD. The muscles remain constantly tense and contracted so that the person aches or feels stiff. The rigidity becomes obvious when another person tries to move the individuals arm, which will move only in ratchet-like or short, jerky movements known as cogwheel rigidity.
- Bradykinesia. This slowing down of spontaneous and automatic movement is particularly frustrating because it may make simple tasks difficult. The person cannot rapidly perform routine movements. Activities once performed quickly and easilysuch as washing or dressingmay take much longer. There is often a decrease in facial expressions.
- Postural instability. Impaired balance and changes in posture can increase the risk of falls.

Parkinsons Disease Late Stage
This is when the person will need assistance with pretty much all of their personal care. As symptoms progress, they will require assistance walking, and eventually it will be impossible to even stand. Some individuals may experience hallucinations and delusions, as well as other non-movement symptoms.
Talk with your medical team about all the ways to help reduce the person you care forâs pain or suffering and increase their comfort. Remember, you are their connection to quality care and services when they can no longer advocate for themselves.
There may come a time when the person living with Parkinsonâs requires a higher level of care than can be provided at home. For some, the transition to a nursing facility can be a tough but necessary decision. You may feel like youâve failed or youâre breaking a promise â even when you know that moving them will provide better care and safety.
If youâre considering a skilled nursing facility, itâs helpful to get a list of local options and be sure to visit. Even if the person you care for is living in a skilled nursing facility, your role as a caregiver does not end. Your presence and advocacy will help ensure that proper care is provided.
What Research Is Being Done
The mission of the National Institute of Neurological Disorders and Stroke is to seek fundamental knowledge about the brain and nervous system and to use the knowledge to reduce the burden of neurological disease. NINDS is a component of the National Institutes of Health , the leading supporter of biomedical research in the world. NINDS conducts and supports three types of research: basicscientific discoveries in the lab, clinicaldeveloping and studying therapeutic approaches to Parkinsons disease, and translationalfocused on tools and resources that speed the development of therapeutics into practice. The goals of NINDS-supported research on Parkinsons disease are to better understand and diagnose PD, develop new treatments, and ultimately, prevent PD. NINDS also supports training for the next generation of PD researchers and clinicians and serves as an important source of information for people with PD and their families.

Parkinsons Disease Middle Stage
In the middle stages of Parkinsonâs, tremors, rigidity, and other movement symptoms will progress. The individual may experience more problems with walking and balance issues that will make falls more common. This can be coupled with slower mental processing, language, and with visual-spatial difficulties. Youâll need to help with basic personal care such as bathing, dressing, and brushing teeth.
Hospice And End Of Life Care
Hospice services are designed to support individuals towards the end of life. Care can be provided wherever the person resides â including at home or in a care facility. This includes visiting nurses, pain management, and personal care. Hospice can also provide spiritual, grief, and bereavement support as well as respite for family caregivers.
Hospice is a Medicare benefit and individuals are eligible when a doctor has determined a patient has 6 months or less to live. Ask your doctor for a referral to begin services, or hospice can assist you in getting a referral if the patient is eligible.

Key Programs And Resources
The Parkinsons Disease Biomarkers Programs , a major NINDS initiative, is aimed at discovering ways to identify individuals at risk for developing PD and Lewy Body Dementia and to track the progression of the disease. It funds research and collects human biological samples and clinical data to identify biomarkers that will speed the development of novel therapeutics for PD. Goals are improving clinical trials and earlier diagnosis and treatment. Projects are actively recruiting volunteers at sites across the U.S. NINDS also collaborates with the Michael J. Fox Foundation for Parkinsons Research on BioFIND, a project collecting biological samples and clinical data from healthy volunteers and those with PD. For more information about the PDBP and how you can get involved, please visit the PDBP website.
The NINDS Morris K. Udall Centers of Excellence for Parkinsons Disease Research program supports research centers across the country that work collaboratively to study PD disease mechanisms, the genetic contributions to PD, and potential therapeutic targets and treatment strategies.
The NINDS Intramural Research Program conducts clinical studies to better understand PD mechanisms and develop novel and improve treatments.
The NINDS Biospecimens Repositories store and distribute DNA, cells, blood samples, cerebrospinal fluid, and autopsy tissue to PD researchers around the world.
Environmental Factors And Exposures
Exposure to pesticides and a history of head injury have each been linked with PD, but the risks are modest. Never drinking caffeinated beverages is also associated with small increases in risk of developing PD.
Low concentrations of urate in the blood is associated with an increased risk of PD.
Different medical drugs have been implicated in cases of parkinsonism. Drug-induced parkinsonism is normally reversible by stopping the offending agent. Drugs include:

Caring For The Mind Body And Spirit
The Muhammad Ali Parkinson Center is the most comprehensive center of its kind in the nation. Barrow neurologists and neurosurgeons are world leaders in deep brain stimulation surgery and treatment for managing the symptoms of movement disorders. In addition to surgical treatment, patients are offered a wide range of recreational therapies, such as group exercise classes and art workshops, and educational classes and support groups that benefit the mind, body and spirit.
Thanks to a generous donation from The Bob & Renee Parsons Foundation, the Muhammad Ali Parkinson Center is taking its innovative care into the homes of housebound patient utilizing telemedicine through the Lonnie and Muhammad Ali Legacy Care Program. The program brings the same high quality care that Muhammad Ali received to patients throughout Arizona.
Medical Care And Nutrition
As the disease progresses, swallowing issues, along with speech and voice disorders, can have a significant impact on the personâs quality of life.
Speech Therapist: It is recommended that the person you care for get a baseline speech evaluation, along with speech therapy, to help with difficulty talking and swallowing.
Dietitian: A dietitian can provide guidance on proper nutrition and create individualized meal plans as food can impact medications and non-movement symptoms. Dietitians can also help with planning the timing of meals and medications.
Palliative Care helps to improve the quality of life for people who have debilitating chronic health conditions. Palliative care teams can help manage symptoms and reduce suffering. A person does not have to be in hospice to qualify.
Contact the medical team for referrals to any of these services. And if itâs difficult to attend an appointment in-person, ask providers about tele-health or virtual visit options.

What Is The Prognosis
The average life expectancy of a person with PD is generally the same as for people who do not have the disease. Fortunately, there are many treatment options available for people with PD. However, in the late stages, PD may no longer respond to medications and can become associated with serious complications such as choking, pneumonia, and falls.
PD is a slowly progressive disorder. It is not possible to predict what course the disease will take for an individual person.
One commonly used scale neurologists use for describing how the symptoms of PD have progressed in a patient is the Hoehn and Yahr scale.
Legal And Financial Planning
One common question that caregivers ask, is what will happen to the person I care for if something happens to me? One thing you can do is make sure that your own legal and financial documents are updated.
This is also a good time to encourage the person with Parkinsonâs to make or update their legal and financial arrangements including making arrangements for dependents, especially before they experience significant cognitive changes. For them itâs best to speak with an attorney who specializes in disability and estate planning. Key documents to complete include:
- Durable financial power of attorney
- Advance Health Care Directive
- Will and/or trust
- POLST form which specifies end-of-life medical intervention.
This is also a good time for the person with Parkinsonâs to sign a release of information, allowing medical staff to speak with you and others who are closely involved in their care.
If you or the person with Parkinsonâs is employed, it is important to contact the Human Resources department to learn about eligible benefits, such as long-term disability and paid and unpaid family leave options.
Securing financial help from the government can be a challenging and confusing process. Seek out experts to help you early on. Consult with an attorney, a community organization or legal aid office that specializes in Social Security Disability Insurance and Supplemental Security Income . They can also help you navigate Medicare and Medicaid.

Parkinson Research At The Ottawa Hospital
Parkinson’s disease is the second most common neurodegenerative disease after Alzheimer’s, affecting at least 100,000 Canadians. Only through a better understanding of the basic mechanisms that cause it can effective treatments be developed.
Imagine not being able to control a trembling in your hands and limbs, the inability to speak loudly, losing your sense of smell, dealing with unexplained pains. Unfortunately, these are just a few of the symptoms affecting Parkinsons disease patients every day.
More than 100,000 Canadians live with Parkinsons, including 8,000 here in Ottawa. Parkinsons is a progressive neurodegenerative disease that primarily affects voluntary, controlled movement. The exact cause of the disease is unknown. Discovered almost 200 years ago, there is still no cure or proven treatment available to slow its relentless progression. People can develop Parkinsons disease at any time in their life.
Our society will be faced with many more patients with Parkinsons over the decades to come. In many ways Parkinsons is complicated and also complex. I strongly believe that although its complex and complicated, we can solve that riddle. We have the expertise in Canada to make a major contribution to a cure for this disease.

What Genes Are Linked To Parkinsons Disease
Several genes have been definitively linked to PD:
- SNCA. This gene, which makes the protein alpha-synuclein, was the first gene identified to be associated with Parkinsons. Research findings by the National Institutes of Health and other institutions prompted studies of the role of alpha-synuclein in PD, which led to the discovery that Lewy bodies seen in all cases of PD contain clumps of alpha-synuclein. This discovery revealed the link between hereditary and sporadic forms of the disease.
- LRRK2. Mutations in LRRK2 were originally identified in several English and Basque families as a cause of a late-onset PD. Subsequent studies have identified mutations of this gene in other families with PD as well as in a small percentage of people with apparently sporadic PD. LRRK2 mutations are a major cause of PD in North Africa and the Middle East.
- DJ-1. This gene normally helps regulate gene activity and protect cells from oxidative stress and can cause rare, early forms of PD.
- PRKN . The parkin gene is translated into a protein that normally helps cells break down and recycle proteins.
- PINK1. PINK1 codes for a protein active in mitochondria. Mutations in this gene appear to increase susceptibility to cellular stress. PINK1 has been linked to early forms of PD.
- GBA . Mutations in GBA cause Gaucher disease , but different changes in this gene are associated with an increased risk for Parkinsons disease as well.
Do Symptoms Get Worse
PD does not affect everyone the same way. The rate of progression and the particular symptoms differ among individuals.
PD symptoms typically begin on one side of the body. However, the disease eventually affects both sides, although symptoms are often less severe on one side than on the other.
Early symptoms of PD may be subtle and occur gradually. Affected people may feel mild tremors or have difficulty getting out of a chair. Activities may take longer to complete than in the past. Muscles stiffen and movement may be slower. The persons face may lack expression and animation . People may notice that they speak too softly or with hesitation, or that their handwriting is slow and looks cramped or small. This very early period may last a long time before the more classical and obvious motor symptoms appear.
As the disease progresses, symptoms may begin to interfere with daily activities. Affected individuals may not be able to hold utensils steady or they may find that the shaking makes reading a newspaper difficult.
People with PD often develop a so-called parkinsonian gait that includes a tendency to lean forward, taking small quick steps as if hurrying , and reduced swinging in one or both arms. They may have trouble initiating movement , and they may stop suddenly as they walk .
