Causes Of Parkinsons Disease
Parkinsons disease is caused by a loss of nerve cells in part of the brain called the substantia nigra. This leads to a reduction in a chemical called dopamine in the brain.
Dopamine plays a vital role in regulating the movement of the body. A reduction in dopamine is responsible for many of the symptoms of Parkinsons disease.
Exactly what causes the loss of nerve cells is unclear. Most experts think that a combination of genetic and environmental factors is responsible.
Can Seniors With Parkinsons Live Long Lives
By Rob Buck 9 am on July 25, 2019
Parkinsons disease is still a fairly misunderstood condition, so many seniors start worrying about their mortality when theyre diagnosed with Parkinsons. This is perfectly understandable, but the reality is that Parkinsons itself isnt a fatal disease. Those with the condition have the potential to live long, fulfilling lives. Heres what you need to know about life expectancy for seniors with Parkinsons.
Parkinsons Disease Symptoms: Life Expectancy
Even though Parkinsons disease is a serious, progressive condition, it is not considered a fatal illness. People who have Parkinsons disease usually have the same average life expectancy as people without the disease.
But when the disease is in its advanced stages, Parkinsons symptoms can lead to life-threatening complications, including:
- Falls that lead to fractured bones
- Pneumonia
- Choking
Thinking about the progression of Parkinsons disease can be frightening. But proper treatments can help you live a full, productive life for years to come. And researchers hope to one day find ways to halt the progression of Parkinsons and restore lost functioning.

How Is Parkinsons Treated
Parkinsons disease in itself doesnt have a cure. However, doctors can slow the progression of the disease and treat some of the symptoms. Lifestyle changes, medication, physical therapy, occupational therapy, speech therapy, rest, and other types of therapy may prevent the disease from advancing to stage five or at least delay the advancement.
Normal Cognition Early In Pd Predicted Normal Life Expectancy
Parkinsons disease patients who had normal cognitive function at the start of a prospective, community-based study had a largely normal life expectancy, researchers reported.
But Parkinsons disease patients who had early freezing of gait, severe hyposmia, cognitive impairment, or subtle inflammation in their cerebrospinal fluid had a significantly shorter life span, reported David Backstrom, MD, of Umea University in Sweden, and colleagues in Neurology.
Action Points
- Patients with Parkinsons disease who have mild disease and normal cognition at onset have a mortality rate equivalent to that of the general population, according to a Swedish study of 182 patients with new-onset, idiopathic parkinsonism.
- Recognize that patients with incident parkinsonism have overall reduced survival, but that the survival is highly dependent on the type and characteristics of the parkinsonian disorder.
The prognosis of Parkinsons disease and parkinsonism is best studied by long-term follow-up of community-based incident cohorts, Backstrom told MedPage Today. Mortality among Parkinsons disease patients can be highly variable, and this study provides a better characterization of the neurobiological factors that are associated with short survival in Parkinsons disease.

Average Life Expectancy For Seniors With Parkinsons
On average, a person with Parkinsons disease dies at the age of 81, which is equal to national life expectancy rates. Depending on age and location, overall life expectancy is somewhere between the ages of 78 and 81. However, overall life expectancy rates are skewed a little by the fact that more young people engage in risky behavior that can cause earlier death. Those who manage to survive to the age of 65 actually have a longer life expectancy84 to 86 yearswhich means seniors with Parkinsons have a slightly shorter life span than other seniors, but they still have a fairly normal life span when compared to the general population.
The Role Of Dementia And Age
Dementia also plays an important role in survival with Parkinson’s. By the end of the above study, nearly 70% of the population with Parkinson’s had been diagnosed with dementia, and those with dementia had a lower survival rate as compared to those without.
This means that those with dementia were more likely to die during the six-year period than those without dementia. In addition, scientific studies have shown that increasing age is linked to an increased risk of death.
It’s important to remember that how a person’s Parkinson’s disease manifests and progresses is variable, and a person’s neurologist cannot accurately predict individual life expectancy.
There are simply no key signs or symptoms that allow a healthcare provider to perfectly predict longevity. An older age and the presence of dementia are simply associated with an increased risk of dying.

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.
Who Is Affected By Tremor
About 70% of people with Parkinsons experience a tremor at some point in the disease. Tremor appears to be slightly less common in younger people with PD, though it is still one of the most troublesome symptoms. People with resting tremor usually have a more slowly progressing course of illness than people without tremor.

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.
Are There Medicines To Treat Pdd
Though there is no cure for PDD yet, there are medications that help manage the symptoms. These medications are called cholinesterase inhibitors, and they can help if a person with PDD is having memory problems. Some examples of these medicines are donepezil, rivastigmine and galantamine. Sleep problems may be managed by sleep medications such as melatonin.
Because people with PDD are usually very sensitive to medications, any new medication, even one that is not being used for the brain, needs to be reviewed with the persons provider to avoid potential contraindication.

Mayo Clinic Q And A: Rate Of Progression Of Parkinsons Disease Hard To Predict
DEAR MAYO CLINIC: My father is 64 and was diagnosed with Parkinsons last year. So far his symptoms are very mild, but Im wondering what the typical progression of the disease is like. I have read that deep brain stimulation is sometimes recommended. When is this type of treatment usually considered? Is it safe?
ANSWER: The symptoms of Parkinsons disease, or PD, tend to begin very gradually and then become progressively more severe. The rate of progression is hard to predict and is different from one person to another. Treatment for PD includes a variety of options, such as exercise, medication and surgery. Deep brain stimulation is one surgical possibility for treating PD, but its usually only considered in advanced cases when other treatments dont effectively control symptoms.
Parkinsons disease is a syndrome which typically has no known cause. The diagnosis is based on symptoms. Neurologists who specialize in movement disorders typically have the most experience with PD diagnosis and treatment. There are many symptoms of parkinsonism. The most common include excessive slowness and lack of movement, as well as shaking or tremor.
As in your fathers situation, symptoms are often mild at the outset. How quickly they get worse varies substantially, perhaps because there may be multiple underlying causes of the disease. In most cases, symptoms change slowly, with substantive progression taking place over the space of many months or years.
What Are The Symptoms Of Parkinson Disease
Parkinson disease symptoms usually start out mild, and then progressively get much worse. The first signs are often so subtle that many people dont seek medical attention at first. These are common symptoms of Parkinson disease:
- Tremors that affect the face and jaw, legs, arms, and hands
- Slow, stiff walking

Hospice Eligibility For Parkinsons Disease
Due to the progressive nature of Parkinsons disease, it can be challenging for families to know when their loved one is eligible for the support of hospice care. If a loved one has been diagnosed with six months or less to live or if they have experienced a decline in their ability to move, speak, or participate in the activities of daily living without caregiver assistance, it is time to speak with a hospice professional about next steps.

The Life Expectancy Is Unpredictable For Patients With Parkinsons Disease
There are cases when people were diagnosed with Parkinsons and had lived for several years after their initial diagnosis. The patient needs to understand that Parkinsons disease is a progressive disease that gets worse with time. And there is no assuring cure for it.
The rate of its growth also differs from person to person. Medical research is conducting extensive research to find a cure. However, a lot has yet to be discovered.
The symptoms can be controlled or slowed down through surgical interventions, medicines, and therapeutic methodologies, such as rigidity, tremors, slowness of movements, etc. With time the patient might face other difficulties, such as losing his sense of smell and sound and facing great hardships in completing his activities of daily living.
In the past, when there was not sufficient medical research on Parkinsons or it was still in progress, the average life expectancy was only 10 years. But after the discovery of levodopa, the expectancy increased.
And now, the life expectancy of a Parkinsons patient has significantly improved due to many medical advances and research. Many believed that if the symptoms were controlled, the patient might have a chance of living a longer life.

Who Gets Early Onset Parkinsons Disease
About 10%-20% of those diagnosed with Parkinsons disease are under age 50, and about half of those are diagnosed before age 40. Approximately 60,000 new cases of Parkinsons are diagnosed each year in the United States, meaning somewhere around 6,000 12,000 are young onset patients.
Is it genetic or hereditary?
The cause of Parkinsons disease is not yet known. However, Parkinsons disease has appeared across several generations of some families, which could indicate that certain forms of the disease are hereditary or genetic. Many researchers think that Parkinsons disease may be caused by genetic factors combined with other external factors. The field of genetics is playing an ever greater role in Parkinsons disease research, and scientists are continually working towards determining the cause or causes of PD.

Reported Standardised Mortality Ratios From 1935 To 2001
The SMRs or mortality ratios comparing PD cases and controls from 39 studies from 1935 to 2006 are reported in table 1. The SMRs ranged from 1, indicating no differences compared with the general population, to 3.4, indicating more than threefold higher mortality in PD. The time trend of estimates is inconsistent, although there appears to be a decrease in the 1970s, corresponding to the introduction of levodopa trials during that time period .). A geographical trend is not apparent, as the SMRs within each geographical region are as variable as between regions .

Caring For Your Health With Parkinson’s Disease
In addition to caring for your Parkinson’s health, it is also important to care for your overall health. This means visiting your primary care physician periodically for preventive care like the annual flu shot and cancer screeningsfor example, a mammogram for breast cancer screening and a colonoscopy for colon cancer screening.
A primary care physician can also evaluate for risk factors related to heart attacks and strokes, and provide counseling on exercise, smoking, alcohol use, depression, or other mental health concerns. Regular visits to your primary care physician or neurologist will also allow them to catch bacterial infections like urinary tract infections before they get serious.

How Do I Prevent Falls From Common Hazards
- Floors: Remove all loose wires, cords, and throw rugs. Minimize clutter. Make sure rugs are anchored and smooth. Keep furniture in its usual place.
- Bathroom: Install grab bars and non-skid tape in the tub or shower. Use non-skid bath mats on the floor or install wall-to-wall carpeting.
- Lighting: Make sure halls, stairways, and entrances are well-lit. Install a night light in your bathroom or hallway and staircase. Turn lights on if you get up in the middle of the night. Make sure lamps or light switches are within reach of the bed if you have to get up during the night.
- Kitchen: Install non-skid rubber mats near the sink and stove. Clean spills immediately.
- Stairs: Make sure treads, rails, and rugs are secure. Install a rail on both sides of the stairs. If stairs are a threat, it might be helpful to arrange most of your activities on the lower level to reduce the number of times you must climb the stairs.
- Entrances and doorways: Install metal handles on the walls adjacent to the doorknobs of all doors to make it more secure as you travel through the doorway.
Complications Related To Parkinsons Can Affect Survival
Claudia Chaves, MD, is board-certified in cerebrovascular disease and neurology with a subspecialty certification in vascular neurology. She is an associate professor of neurology at Tufts Medical School and medical director of the Lahey Clinic Multiple Sclerosis Center in Lexington, Massachusetts.
Parkinsons is a common neurodegenerative disease, and although it is not fatal, research suggests it may influence life expectancy.
A 2012 study in Archives of Neurology examined the six-year survival of nearly 140,000 Medicare beneficiaries with Parkinsons disease in the United States. During the six-year period, 64% of the participants with Parkinsons disease passed away.
The risk of death of those with Parkinsons was then compared to Medicare beneficiaries who did not have Parkinsons or any other common diseases, including:
When controlling for variables like age, race, and gender, the six-year risk of death among people with Parkinsons was found to be nearly four times greater than those Medicare beneficiaries without the disease or other common diseases.
At the same time, the rate of death among those with Parkinsons disease was similar to those with hip fracture, Alzheimers dementia, or a recent heart attackalthough it was higher than those who had been newly diagnosed with either colorectal cancer, stroke, ischemic heart disease, or chronic obstructive pulmonary disease.

Does Parkinsons Affect Your Lifespan
Parkinsons research and treatments have come a long way, so much so that the average life span of a person with Parkinsons is the same or near the same as someone without Parkinsons disease. However, the lifespan of a person can vary widely based upon that persons health choices, such as their diet, exercise routine, if they have a history of smoking and many other factors. So, for most people with Parkinsons, as long as you focus on managing your Parkinsons disease and make healthy choices your lifespan should not be shortened.
What Are The Five Stages Of Parkinson’s Disease
Researchers may disagree on the number of stages of Parkinsons disease . However, they all agree the disease is a progressive disease with symptoms that usually occur in one stage may overlap or occur in another stage. The stage increase in number value for all stage naming systems reflect the increasing severity of the disease. The five stages used by the Parkinsons Foundation are:
- Stage 1: mild symptoms do not interfere with daily activities and occur on one side of the body.
- Stage 2: Symptoms worsen with walking problems and both sides of the body affected.
- Stage 3: Main symptoms worsen with loss of balance and slowness of movement.
- Stage 4: Severity of symptoms require help usually person cannot live alone.
- Stage 5:Caregiver needed for all activities patient may not be able to stand or walk and may be bedridden and may also experience hallucinations and delusions.
A neurologist who specializes in movement disorders will be able to make the most accurate diagnosis. An initial assessment is made based on medical history, a neurological exam, and the symptoms present. For the medical history, it is important to know whether other family members have Parkinson’s disease, what types of medication have been or are being taken, and whether there was exposure to toxins or repeated head trauma previously. A neurological exam may include an evaluation of coordination, walking, and fine motor tasks involving the hands.
The diagnosis of Parkinson’s disease is more likely if:
