Theory Of Pd Progression: Braaks Hypothesis
The current theory is that the earliest signs of Parkinson’s are found in the enteric nervous system, the medulla and the olfactory bulb, which controls sense of smell. Under this theory, Parkinson’s only progresses to the substantia nigra and cortex over time.
This theory is increasingly borne out by evidence that non-motor symptoms, such as a loss of sense of smell , sleep disorders and constipation may precede the motor features of the disease by several years. For this reason, researchers are increasingly focused on these non-motor symptoms to detect PD as early as possible and to look for ways to stop its progression.

What Lifestyle Changes Can I Make To Ease Parkinsons Symptoms
Exercise helps improve muscle strength, balance, coordination, flexibility, and tremor. It is also strongly believed to improve memory, thinking and reduce the risk of falls and decrease anxiety and depression. One study in persons with Parkinsons disease showed that 2.5 hours of exercise per week resulted in improved ability to move and a slower decline in quality of life compared to those who didnt exercise or didnt start until later in the course of their disease. Some exercises to consider include strengthening or resistance training, stretching exercises or aerobics . All types of exercise are helpful.
Eat a healthy, balanced diet: This is not only good for your general health but can ease some of the non-movement related symptoms of Parkinsons, such as constipation. Eating foods high in fiber in particular can relieve constipation. The Mediterranean diet is one example of a healthy diet.
Preventing falls and maintaining balance: Falls are a frequent complication of Parkinson’s. While you can do many things to reduce your risk of falling, the two most important are: 1) to work with your doctor to ensure that your treatments whether medicines or deep brain stimulation are optimal; and 2) to consult with a physical therapist who can assess your walking and balance. The physical therapist is the expert when it comes to recommending assistive devices or exercise to improve safety and preventing falls.
Signs Of Parkinsons Disease
In 1817, Dr. James Parkinson published An Essay on the Shaking Palsy describing non-motor, as well as, motor symptoms of the illness that bears his . Parkinsons is not just a movement disorder, explained Dr. Shprecher. Constipation, impaired sense of smell, and dream enactment can occur years before motor symptoms of Parkinsons. The latter, caused by a condition called REM sleep behavior disorder, is a very strong risk factor for both Parkinsons and dementia . This has prompted us to join a of centers studying REM sleep behavior disorder.
Treating Parkinsons Disease Dementia
A treatment plan for PDD typically includes medications that boost the brains level of certain neurotransmitters and help improve memory and processing speed, Dr. Petrossian says. Exercise is also an important part of the treatment planDr. Petrossian recommends skill-based activities like boxing or dance to boost cognitive function as well as fitness. PDD symptoms should be monitored long-term by a neurologist, and in some cases a psychiatrist, says Dr. Okun. In many cases, physical, occupational, speech, and social work therapy can also be useful since PPD affects all aspects of life.
Stooping Or Hunching Over
Are you not standing up as straight as you used to? If you or your family or friends notice that you seem to be stooping, leaning or slouching when you stand, it could be a sign of Parkinson’s disease .
What is normal?If you have pain from an injury or if you are sick, it might cause you to stand crookedly. Also, a problem with your bones can make you hunch over.
What Are The Surgical Treatments For Parkinsons Disease
Most patients with Parkinsons disease can maintain a good quality of life with medications. However, as the disease worsens, medications may no longer be effective in some patients. In these patients, the effectiveness of medications becomes unpredictable reducing symptoms during on periods and no longer controlling symptoms during off periods, which usually occur when the medication is wearing off and just before the next dose is to be taken. Sometimes these variations can be managed with changes in medications. However, sometimes they cant. Based on the type and severity of your symptoms, the failure of adjustments in your medications, the decline in your quality of life and your overall health, your doctor may discuss some of the available surgical options.
How Do I Know If I Have A Swallowing Problem
- I have recently lost weight without trying.
- I tend to avoid drinking liquids.
- I get the sensation of food being stuck in my throat.
- I tend to drool.
- I notice food collecting around my gum line.
- I tend to cough or choke before, during or after eating or drinking.
- I often have heartburn or a sore throat.
- I have trouble keeping food or liquid in my mouth.

What Causes Parkinsons Disease
Parkinsons disease occurs when nerve cells in an area of the brain called the substantia nigra become impaired or die. These cells normally produce dopamine, a chemical that helps the cells of the brain communicate . When these nerve cells become impaired or die, they produce less dopamine. Dopamine is especially important for the operation of another area of the brain called the basal ganglia. This area of the brain is responsible for organizing the brains commands for body movement. The loss of dopamine causes the movement symptoms seen in people with Parkinsons disease.
People with Parkinsons disease also lose another neurotransmitter called norepinephrine. This chemical is needed for proper functioning of the sympathetic nervous system. This system controls some of the bodys autonomic functions such as digestion, heart rate, blood pressure and breathing. Loss of norepinephrine causes some of the non-movement-related symptoms of Parkinsons disease.
Scientists arent sure what causes the neurons that produce these neurotransmitter chemicals to die.
How Is Parkinsons Disease Treated
There is no cure for Parkinsons disease. However, medications and other treatments can help relieve some of your symptoms. Exercise can help your Parkinsons symptoms significantly. In addition, physical therapy, occupational therapy and speech-language therapy can help with walking and balance problems, eating and swallowing challenges and speech problems. Surgery is an option for some patients.
Parkinson’s Disease Diet And Nutrition
Maintaining Your Weight With Parkinson’s Disease
Malnutrition and weight maintenance is often an issue for people with Parkinson’s disease. Here are some tips to help you maintain a healthy weight.
- Weigh yourself once or twice a week, unless your doctor recommends weighing yourself often. If you are taking diuretics or steroids, such as prednisone, you should weigh yourself daily.
- If you have an unexplained weight gain or loss , contact your doctor. He or she may want to modify your food or fluid intake to help manage your condition.
- Avoid low-fat or low-calorie products. . Use whole milk, whole milk cheese, and yogurt.
Fluid And Tissue Biomarkers
Given the supposed central importance of -synuclein to the disease process, recent biomarker strategies have centred on finding and characterising forms of the protein in a range of biofluids and tissues. Blood has been a disappointing target to-date because red cells contain large quantities of -synuclein, obscuring any theoretical difference in levels between patients and controls, but some group differences have been demonstrated for DJ-1, urate, vitamin D and IGF-1 . Plasma apoliprotein A1 has been shown to differentiate patients from healthy controls and, interestingly, also to correlate with DaT SPECT deficit in hyposmic subjects with a family history of PD, recruited from the PARS study.
It is believed that cerebrospinal fluid is most likely to show changes representative of disease occurring in the brain. Nonetheless, lumbar puncture is an invasive and costly procedure compared with blood draw, and is likely to remain most appropriate for use in clinical trials and in specific clinical practice settings, unless a high-performing biomarker can be identified. Potential CSF biomarkers for PD include -synuclein and DJ-1, with A42 potentially correlating with cognitive impairment, and various forms of tau protein and neurofilament light-chain differentiating PD from atypical parkinsonian disorders. Separately, observed biomarker changes in saliva have included reduction in -synuclein levels and elevation of DJ-1 in the saliva .
Trouble Moving Or Walking
Do you feel stiff in your body, arms or legs? Have others noticed that your arms dont swing like they used to when you walk? Sometimes stiffness goes away as you move. If it does not, it can be a sign of Parkinson’s disease. An early sign might be stiffness or pain in your shoulder or hips. People sometimes say their feet seem stuck to the floor.
What is normal?If you have injured your arm or shoulder, you may not be able to use it as well until it is healed, or another illness like arthritis might cause the same symptom.
Is Parkinsons Disease Inherited
Scientists have discovered gene mutations that are associated with Parkinsons disease.
There is some belief that some cases of early-onset Parkinsons disease disease starting before age 50 may be inherited. Scientists identified a gene mutation in people with Parkinsons disease whose brains contain Lewy bodies, which are clumps of the protein alpha-synuclein. Scientists are trying to understand the function of this protein and its relationship to genetic mutations that are sometimes seen in Parkinsons disease and in people with a type of dementia called Lewy body dementia.
Several other gene mutations have been found to play a role in Parkinsons disease. Mutations in these genes cause abnormal cell functioning, which affects the nerve cells ability to release dopamine and causes nerve cell death. Researchers are still trying to discover what causes these genes to mutate in order to understand how gene mutations influence the development of Parkinsons disease.
Scientists think that about 10% to 15% of persons with Parkinsons disease may have a genetic mutation that predisposes them to development of the disease. There are also environmental factors involved that are not fully understood.

Stages In Parkinsons Disease
Staging is Not Important in Evaluating Parkinsons Disease
Patients often ask what stage of PD that they are in. I then explain the following as to why that is not an important issue.
Staging in most diseases is important in predicting how long people will live or how well they can function. This is particularly important in and heart disease. Different cancers have different systems for staging as experience has accumulated to distinguish how ominous it is to have cancer spread to local lymph nodes, or distant nodes, above the diaphragm, or below the diaphragm, in the bone marrow or not, etc. So stage 2b in one disease may have a very different prognosis than stage 2b in another form of cancer, but each will be associated with a certain chance of survival for a specified period.
This is not true for staging in PD. The staging system we use is based on a famous paper written by Margaret Hoehn and Melvin Yahr in 1967. Their paper was the first large study of the effect of LDopa on disease progression. In order to assess how the disease progressed, they had to develop a system to rate the severity. It wouldnt do, for example, to say mild,moderate, or severe, as the readers would want to know what they meant by these terms.
Early Signs Of Parkinsons Disease Dementia
In the beginning, PDD can be subtle. Early on, there may be memory loss and difficulties with daily activities, says Michael S. Okun, M.D., executive director of the Norman Fixel Institute for Neurological Diseases at University of Florida Health in Gainesville. Delusions or hallucinations may also start to happen. Dr. Petrossian points out that there can be an overlap between the early signs of dementia and mild cognitive impairment due to Parkinsons disease, which can make it difficult to learn new skills and recall information or conversations.
Stage Two Of Parkinsons Disease
Stage two is still considered early disease in PD, and it is characterized by symptoms on both sides of the body or at the midline without impairment to balance. Stage two may develop months or years after stage one.
Symptoms of PD in stage two may include the loss of facial expression on both sides of the face, decreased blinking, speech abnormalities, soft voice, monotone voice, fading volume after starting to speak loudly, slurring speech, stiffness or rigidity of the muscles in the trunk that may result in neck or back pain, stooped posture, and general slowness in all activities of daily living. However, at this stage the individual is still able to perform tasks of daily living.
Diagnosis may be easy at this stage if the patient has a tremor; however, if stage one was missed and the only symptoms of stage two are slowness or lack of spontaneous movement, PD could be misinterpreted as only advancing age.
Stage One: Symptoms Affect Only One Side Of Your Body
The initial phase of Parkinsons disease typically presents with mild symptoms. Some patients will not even detect their symptoms in the earliest phases of this stage. Typical motor symptoms experienced in Stage One include tremors and shaking limbs. Family members and friends may begin to notice other symptoms including tremor, poor posture, and mask face or loss of facial expression.
Some Of The Risk Factors Include The Following:
- Men are more likely to get Parkinsons than women.
- Whites are more susceptible to get PD than African Americans or Asians.
- People who are in the age group of 50 and 60 are more susceptible to suffer. Only a small percentage of people who are in the age group of fewer than 40 years may get affected.
- People with close family members with PD are more prone to develop the disease.
- Exposure to certain environmental toxins may increase the risk of developing PD.
- People with head injuries are also more likely to develop Parkinsons disease.
Unilateral Involvement Only Usually With Minimal Or No Functional Impairment
The patient has tremor, rigidity, slowness and paucity of movement, or poor condition in the arm and/or legs on one side of the body. Occasionally one side of the face is involved, producing an asymmetry of expression that may look very like the effects of a mild stroke or Bells palsy. This stage of Parkinsons is often missed entirely. For example when the diagnosis is made at a more advanced Stage, the patient may remember having noticed an intermittent tremor of one hand many years before. Old home movies may show that the patient didnt swing one arm as much as the other did while walking. One hand or foot may have been clumsier than the other may have. Often these symptoms are so mild that no formal medical attention is sought. If sought it is not uncommon that the physician is unable to make a diagnosis, either by the most assiduous and astute physical examination or by the most advanced technology. Sometimes the disease must evolve over many years before a diagnosis can be made with certainty.
Usually was inserted into the original definition to modify minimal or no functional impairment: because, very rarely, a patient presents with very severe and disabling unilateral symptoms: extreme and violent tremor or rigidity and akinesia in one limb so severe that the limb is virtually paralyzed. Most doctors worry about a stroke or tumor which they should. When all necessary tests show nothing, one must wait and observe. Eventually Stage II may emerge.
What Causes Parkinson’s Disease
Parkinson’s disease occurs when nerve cells, or neurons, in an area of the brain that controls movement become impaired and/or die. Normally, these neurons produce an important brain chemical known as dopamine. When the neurons die or become impaired, they produce less dopamine, which causes the movement problems of Parkinson’s. Scientists still do not know what causes cells that produce dopamine to die.
People with Parkinson’s also lose the nerve endings that produce norepinephrine, the main chemical messenger of the sympathetic nervous system, which controls many functions of the body, such as heart rate and blood pressure. The loss of norepinephrine might help explain some of the non-movement features of Parkinson’s, such as , irregular blood pressure, decreased movement of food through the digestive tract, and sudden drop in blood pressure when a person stands up from a sitting or lying-down position.
Many brain cells of people with Parkinson’s contain Lewy bodies, unusual clumps of the protein alpha-synuclein. Scientists are trying to better understand the normal and abnormal functions of alpha-synuclein and its relationship to genetic mutations that impact Parkinsons disease and Lewy body dementia.
What Research Is Being Done
The National Institute of Neurological Disorders and Stroke , a component of the National Institutes of Health, is the primary funder of research on the brain and nervous system. is the leading funder of biomedical research in the world.
PSP is one of the diseases being studied as part of the NINDS Parkinsons Disease Biomarkers Program. This major initiative is aimed at discovering ways to identify individuals at risk for developing Parkinsons disease and related disorders, and to track the progression of these diseases. NINDS also supports clinical research studies to develop brain imaging that may allow for earlier and more accurate diagnosis of PSP.
Genetic studies of PSP may identify underlying genetic causes. Previous studies have linked regions of chromosomes containing multiple genes, including the gene for the tau protein , with PSP. Researchers hope to identify specific disease-causing mutation and are also studying how genetics and environment interaction may work together to contribute to disease susceptibility.
Animal models of PSP and other tau-related disorders, including fruit fly and zebrafish models, may identify basic disease mechanisms and lead to preclinical testing of potential drugs. Other studies in animal models focus on brain circuits affected by PSP, such as those involved in motor control and sleep, which may also yield insights into disease mechanisms and treatments.
When Should I Consider Dbs For Parkinsons
Deep brain stimulation is surgery to implant a small device, similar to a heart pacemaker, that controls electrical impulses sent to the brain to disrupt the activity causing your seizures. DBS offers many benefits for people with Parkinsons disease, including fewer tremors to more on time to reduced medications. First approved by the FDA for Parkinsons disease in 2002, DBS is effective in early stages of Parkinsons disease and may extend your life. While every Parkinsons patient must be evaluated to determine if DBS is right for you, below are general criteria:
- Clear diagnosis of idiopathic Parkinsons disease
- Absence of dementia
- Any fluctuations in symptoms with levodopa therapy
- At least some improvement with levodopa therapy
- Lack of serious disease that would prevent surgery
- No age parameters, but patients under 75 generally do better
New research shows that undergoing DBS in the earlier stages of Parkinsons disease is effective, contrary to earlier recommendations that patients must have the disease for at least seven years to benefit. The study also found DBS to be more effective than medications in controlling tremors in patients with Parkinsons disease.
Stage Five Of Parkinsons Disease
Stage five is the most advanced and is characterized by an inability to rise from a chair or get out of bed without help, they may have a tendency to when standing or turning, and they may freeze or stumble when walking.
Around-the-clock assistance is required at this stage to reduce the risk of falling and help the patient with all daily activities. At stage five, the patient may also experience hallucinations or delusions.
While the symptoms worsen over time, it is worth noting that some patients with PD never reach stage five. Also, the length of time to progress through the different stages varies from individual to individual. Not all the symptoms may occur in one individual either. For example, one person may have a tremor but balance remains intact. In addition, there are treatments available that can help at every stage of the disease. However, the earlier the diagnosis, and the earlier the stage at which the disease is diagnosed, the more effective the treatment is at alleviating symptoms.
The 5 Stages Of Parkinsons Disease
Getting older is underrated by most. Its a joyful experience to sit back, relax and watch the people in your life grow up, have kids of their own and flourish. Age can be a beautiful thing, even as our bodies begin to slow down. We spoke with David Shprecher, DO, movement disorders director at Banner Sun Health Research Institute about a well-known illness which afflicts as many as 2% of people older than 65, Parkinsons Disease.
Is There A Cure For Parkinsons Disease
There is no cure for Parkinsons disease, although treatment can help control symptoms so that you can live with the disease. There are a wide variety of surgical and non-surgical treatment options for improving your quality of life. The goals of treatment are to relieve physical disabilities and balance symptom control with medication side effects.
Stages Of Parkinsons Disease
Experts have identified a general Parkinsons progression and created a set of Parkinsons stages, which can help determine where you are at in the disease and what your prognosis might be. However, not everybody progresses through Parkinsons disease in the same way or on the same time frame. Some people skip stages or rapidly progress to later stages. Others live for many years with mild or moderate Parkinsons and never reach the more advanced stage of the illness.
Here are five commonly recognized stages of Parkinsons, including what symptoms you might expect. Treatment also can occur during these stages to help prevent or delay later stages of the illness. This can include medication, , and lifestyle changes, such as a healthy diet and exercise program.
What To Do About Parkinsons Disease
Unfortunately, there currently is no cure for Parkinsons disease. However, there are a variety of treatments available that may be able to help reduce the symptoms and maintain quality of life. Some of these treatments include supportive therapies like physiotherapy as well as medication.
The best way to prompt earlier detection is to understand both the motor and non-motor symptoms of Parkinsons disease. Early detection will help you get earlier treatment and ultimately improve your quality of life.
