What Causes Parkinsons Disease
Parkinsons comes under the dementia umbrella. Its adegenerative disease of the nervous system that causes a loss of motor skillsand intentional movement. When someone has Parkinsons, the part of the brainthat controls muscular movements and mood function doesnt receive enough ofthe crucial dopamine chemical. Without enough dopamine, bodily movements,learning abilities and mood levels are severely affected. So-called normalfunctions such as speaking, writing, swallowing, walking and sleeping become difficultto perform. These challenges, combined with a lowering of mood levels is whymany Parkinsons patients suffer with depression.
Can Parkinsons Disease Be Diagnosed By How You Smell
Theres evidence that people with Parkinsons disease may emit a specific type of scent, which is related to increased sebum production. However, doctors have not developed a way to use this odor to diagnose the disease. More research is being done to see how the finding can help with diagnosis and treatment.
New Diagnostic Standards For Parkinsons
Until recently, the gold-standard checklist for diagnosis came from the U.K.s Parkinsons Disease Society Brain Bank. It was a checklist that doctors followed to determine if the symptoms they saw fit the disease. But thats now considered outdated. Recently, new criteria from the International Parkinson and Movement Disorder Society have come into use. This list reflects the most current understanding of the condition. It allows doctors to reach a more accurate diagnosis so patients can begin treatment at earlier stages.

What Are The Symptoms Of Parkinsons Disease
Symptoms of Parkinsons disease and the rate of decline vary widely from person to person. The most common symptoms include:
Other symptoms include:
- Speech/vocal changes: Speech may be quick, become slurred or be soft in tone. You may hesitate before speaking. The pitch of your voice may become unchanged .
- Handwriting changes: You handwriting may become smaller and more difficult to read.
- Depression and anxiety.
- Sleeping disturbances including disrupted sleep, acting out your dreams, and restless leg syndrome.
- Pain, lack of interest , fatigue, change in weight, vision changes.
- Low blood pressure.
How It All Fits Together
Diagnosing Parkinsons disease can be tricky. The process relies heavily on your doctors judgment. In addition, the causes and risk factors of Parkinsons are not entirely clear yet, which contributes to the difficulty in diagnosing this condition.
However, there have been efforts to try and detect this disease earlier. For instance, clinicians have started focusing more on prodromal symptoms, which are early symptoms that appear before movement-related difficulties begin.
These symptoms include:
- Loss of smell, which can sometimes occur years before other symptoms
- Chronic constipation, without any other explanation
- Rapid eye movement behavior disorder, which causes sleep disturbances

Gait & Balance Abnormalities
Parkinsons Disease Exam
Patients with Parkinsons disease can develop an alteration of the postural reflexes that causes instability in gait and balance control. Such alterations usually develop later in the course of the illness and are a major cause of disability, especially because of the high risk for falls that derives.
Using the exam to pick up postural instability is of the utmost importance for the management of patients with PD, since it will trigger either a medication adjustment or a physical therapy intervention both aimed at falls prevention.
We have three tests for this part of the PD exam:
1) Standing up from a chair
2) Free walking
3) Provoked pull test maneuver for balance
What Is Parkinson’s Disease
Parkinsons disease occurs when brain cells that make dopamine, a chemical that coordinates movement, stop working or die. Because PD can cause tremor, slowness, stiffness, and walking and balance problems, it is called a movement disorder. But constipation, depression, memory problems and other non-movement symptoms also can be part of Parkinsons. PD is a lifelong and progressive disease, which means that symptoms slowly worsen over time.
The experience of living with Parkinson’s over the course of a lifetime is unique to each person. As symptoms and progression vary from person to person, neither you nor your doctor can predict which symptoms you will get, when you will get them or how severe they will be. Even though broad paths of similarity are observed among individuals with PD as the disease progresses, there is no guarantee you will experience what you see in others.
Parkinsons affects nearly 1 million people in the United States and more than 6 million people worldwide.

How To Improve Walking In People With Parkinsons Disease
The reward strategy is It is used to overcome difficulty walking, said Anouk Tosserams, MD and Jorik Nonnekes, MD, researchers at the Radboud University Medical Center in the Netherlands.
Parkinsons disease often causes movement problems such as imbalance, shuffling, falling, staggering, and freezing.
We have found that these strategies are commonly used, but patients awareness of the full range of available strategies is fairly limited, they say.
Individual approaches to rehabilitation and patient education are important, the authors say.
Rebecca Gilbert, MD, Vice President and Chief Scientific Officer of the American Parkinson Disease Association, said the study should help doctors and patients.
Gilbert, an associate professor of neurology at the Bellevue Hospital Center in New York City, said many of the proposals have already been used, but more detailed studies should make the practice more systematic.

Other Causes Of Parkinsonism
“Parkinsonism” is the umbrella term used to describe the symptoms of tremors, muscle rigidity and slowness of movement.
Parkinson’s disease is the most common type of parkinsonism, but there are also some rarer types where a specific cause can be identified.
These include parkinsonism caused by:
- medication where symptoms develop after taking certain medications, such as some types of antipsychotic medication, and usually improve once the medication is stopped
- other progressive brain conditions such as progressive supranuclear palsy, multiple systems atrophy, and corticobasal degeneration
- cerebrovascular disease where a series of small strokes cause several parts of the brain to die

What Are The Primary Motor Symptoms Of Parkinsons Disease
There are four primary motor symptoms of Parkinsons disease: tremor, rigidity, bradykinesia and postural instability . Observing two or more of these symptoms is the main way that physicians diagnose Parkinsons.
It is important to know that not all of these symptoms must be present for a diagnosis of Parkinsons disease to be considered. In fact, younger people may only notice one or two of these motor symptoms, especially in the early stages of the disease. Not everyone with Parkinsons disease has a tremor, nor is a tremor proof of Parkinsons. If you suspect Parkinsons, see a neurologist or movement disorders specialist.
Walking or Gait Difficulties
How Is Parkinsons Disease Diagnosed
Diagnosing Parkinsons disease is sometimes difficult, since early symptoms can mimic other disorders and there are no specific blood or other laboratory tests to diagnose the disease. Imaging tests, such as CT or MRI scans, may be used to rule out other disorders that cause similar symptoms.
To diagnose Parkinsons disease, you will be asked about your medical history and family history of neurologic disorders as well as your current symptoms, medications and possible exposure to toxins. Your doctor will look for signs of tremor and muscle rigidity, watch you walk, check your posture and coordination and look for slowness of movement.
If you think you may have Parkinsons disease, you should probably see a neurologist, preferably a movement disorders-trained neurologist. The treatment decisions made early in the illness can affect the long-term success of the treatment.

Mood And Mental Problems
- Deal with depression. If you are feeling sad or depressed, ask a friend or family member for help. If these feelings don’t go away, or if they get worse, talk to your doctor. He or she may be able to suggest someone for you to talk to. Or your doctor may give you medicine that will help.
- Deal with dementia. Dementia is common late in Parkinson’s disease. Symptoms may include confusion and memory loss. If you notice that you are confused a lot or have trouble thinking clearly, talk to your doctor. There are medicines that can help dementia in people with Parkinson’s disease.
What Is Parkinsons Disease
Parkinsons disease is a progressive neurological disorder. The first signs are problems with movement.
Smooth and coordinated bodily muscle movements are made possible by dopamine, a substance in the brain. Dopamine is produced in a part of the brain called the substantia nigra.
In Parkinsons, the cells of the substantia nigra start to die. When this happens, dopamine levels are reduced. When they have dropped 60 to 80 percent, symptoms of Parkinsons start to appear.
Some of the early symptoms of Parkinsons can begin several years before motor problems develop. These earliest signs include:
- problems with attention and memory
- difficulty with visual-spatial relationships
Early signs of Parkinsons disease may go unrecognized. Your body may try to alert you to the movement disorder many years before movement difficulties begin with these warning signs.
The exact cause of Parkinsons is unknown. It may have both genetic and environmental components. Some scientists believe that viruses can trigger Parkinsons as well.
Low levels of dopamine and norepinephrine, a substance that regulates dopamine, have been linked with Parkinsons.
Abnormal proteins called Lewy bodies have also been found in the brains of people with Parkinsons. Scientists do not know what role, if any, Lewy bodies play in the development of Parkinsons.
While theres no known cause, research has identified groups of people who are more likely to develop the condition, which include:

What Diseases And Conditions Resemble Parkinsons Disease
PD is the most common form of parkinsonism, in which disorders of other causes produce features and symptoms that closely resemble Parkinsons disease. Many disorders can cause symptoms similar to those of PD, including:
Several diseases, including MSA, CBD, and PSP, are sometimes referred to as Parkinsons-plus diseases because they have the symptoms of PD plus additional features.
In very rare cases, parkinsonian symptoms may appear in people before the age of 20. This condition is called juvenile parkinsonism. It often begins with dystonia and bradykinesia, and the symptoms often improve with levodopa medication.
The Importance Of Early Diagnosis
Early detection and diagnosis is important because the treatments for PD are more effective in the early stages of the disease. In addition, physical therapy and exercise, which greatly improve symptoms and delay progression of the disease, are much easier to perform in the early stages.
Current diagnosis is made through the presence of motor symptoms however, researchers have found that by the time motor symptoms occur, over 60% of all dopamine neurons in the basal ganglia of the brain have been damaged. Non-motor symptoms become apparent in people with PD long before motor symptoms, including sleep disturbances and loss of the sense of smell.3
Active areas of research include looking for markers in the blood, urine, or cerebral spinal fluid that reliably detect PD, called biomarkers. In addition, brain imaging tests that have high sensitivity for detecting PD are also being actively researched.4

Deep Brain Stimulation Surgery
As Parkinsons disease progresses, deep brain stimulation surgery may become an option. Our team is one of the most experienced in the United States. Under the direction of Dr. Delaram Safarpour, Dr. Kim Burchiel, an OHSU neurosurgeon, pioneered asleep DBS so you dont have to be awake during surgery.
For this procedure, our team places tiny electrodes in your brain. The electrodes are connected to a small pacemaker-like device placed under the skin of your chest. The device sends mild electrical pulses to regulate movement and control Parkinsons symptoms such as:
In some parts of the state, you can have follow-up care at a doctors office in your community.

What Are The Different Stages Of Parkinsons Disease
Each person with Parkinsons disease experiences symptoms in in their own unique way. Not everyone experiences all symptoms of Parkinsons disease. You may not experience symptoms in the same order as others. Some people may have mild symptoms others may have intense symptoms. How quickly symptoms worsen also varies from individual to individual and is difficult to impossible to predict at the outset.
In general, the disease progresses from early stage to mid-stage to mid-late-stage to advanced stage. This is what typically occurs during each of these stages:
Early symptoms of Parkinsons disease are usually mild and typically occur slowly and do not interfere with daily activities. Sometimes early symptoms are not easy to detect or you may think early symptoms are simply normal signs of aging. You may have fatigue or a general sense of uneasiness. You may feel a slight tremor or have difficulty standing.
Often, a family member or friend notices some of the subtle signs before you do. They may notice things like body stiffness or lack of normal movement slow or small handwriting, lack of expression in your face, or difficulty getting out of a chair.
Standing and walking are becoming more difficult and may require assistance with a walker. You may need full time help to continue to live at home.

Home Remedyfor Parkinsons #5 Vitamin D & Vitamin E:
Inflammation and low immunity are two powerful factorsthat contribute to the development and worsening of Parkinsons disease. Bothvitamin D and vitamin E are strong anti-inflammatories and immune boosters. VitaminD & E also protect our brain cells and can even help damaged neurons regenerate. A deficiency of these key vitamins has also been linked to brain difficultiessuch as poor memory and recall attainability.
In regards to PD, a study of 157 Parkinsons patientsfound that the vast majority of them had severe to chronic vitamin Ddeficiencies. The findings, published in the Archives of Neurology in March of 2011, revealed a strong linkbetween inadequate levels of vitamin D and the onset of early Parkinson’sdisease.4
Back in 2002, another study was published in the Archives of Neurology which tracked themental decline of 3,000 men and women diagnosed with Parkinsons disease over a period of 7 years. The study found the participants whose supplemental vitamin E intakewas higher experienced a 36% reduction in theseverity of their symptoms compared to the rest of the group. Another study, whichappeared in the Lancet Neurology onlinemagazine in 2005, showed that vitamin E may actually prevent Parkinsonsdisease from developing in the first place! 8

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.

Genetic Testing For Parkinsons Disease
Similar to other complex diseases, the reason a particular person develops Parkinsons disease is likely a combination of genetic makeup and environment. In most people, the genetic contribution to disease development may be due to a number of different genes and the interactions between them. For only a very small percentage of people with PD, about 10%, the disease can be attributed to a single abnormal gene. Figuring out the identity and contributions of all the different genes that play a role in disease development is a very hot topic in PD research today.
