Why Do Parkinsons Patients Lose Weight
Several causes may induce weight loss. Weight loss is a non-specific symptom and could be a sign of a wide variety of medical problems, including cancer. Therefore, acute weight loss is an entity that a physician should examine to identify its cause.
Suppose the patient suffers from Parkinsons disease, and the physician does not find any other possible cause. In that case, the weight loss shall be attributed to Parkinsons.
Among PD patients, many possible causes may lead to weight loss. The reasons vary from people to people, but each one can contribute to developing weight loss. People with Parkinsons disease have a decrease in appetite, and it has various possible causes.
- The alteration, in the sense of smell, disables them from tasting food and reducing the amount of food.
- Apathy and depression
- Nausea due to medications
Asides from the appetite loss, other possible causes go along with the motor symptoms of the disease. These motor symptoms may induce an increase in energy expenditure.
- Dyskinesias are pointless and involuntary movements that can be a side effect of the treatment with levodopa.
- Essential tremor, resting tremor, and as well as muscle stiffness can be causes of excessive energy consumption and subsequent weight loss.
Symptoms Of Parkinsons Disease
Parkinson’s disease has four main symptoms:
- Tremor in hands, arms, legs, jaw, or head
- Stiffness of the limbs and trunk
- Slowness of movement
- Impaired balance and coordination, sometimes leading to falls
Symptoms of Parkinsons and the rate of progression differ among individuals. Sometimes people dismiss early symptoms of Parkinson’s as the effects of normal aging. In most cases, there are no medical tests to definitively detect the disease, so it can be difficult to diagnose accurately.
Early symptoms of Parkinson’s disease are subtle and occur gradually. For example, affected people may feel mild tremors or have difficulty getting out of a chair. They may notice that they speak too softly, or that their handwriting is slow and looks cramped or small. Friends or family members may be the first to notice changes in someone with early Parkinson’s. They may see that the person’s face lacks expression and animation, or that the person does not move an arm or leg normally.
People with Parkinson’s often develop a parkinsonian gait that includes a tendency to lean forward, small quick steps as if hurrying forward, and reduced swinging of the arms. They also may have trouble initiating or continuing movement.
Support For People With Parkinsons Disease
Early access to a multidisciplinary support team is important. These teams may include doctors, physiotherapists, occupational therapists, speech therapists, dietitians, social workers and specialist nurses. Members of the team assess the person with Parkinsons disease and identify potential difficulties and possible solutions.There are a limited number of multidisciplinary teams in Victoria that specialise in Parkinsons disease management. But generalist teams are becoming more aware of how to help people with Parkinsons disease.

Is There A Cure For Parkinsons
Theres currently no cure for Parkinsons, a disease that is chronic and worsens over time. More than 50,000 new cases are reported in the United States each year. But there may be even more, since Parkinsons is often misdiagnosed.
Its reported that Parkinsons complications was the
Complications from Parkinsons can greatly reduce quality of life and prognosis. For example, individuals with Parkinsons can experience dangerous falls, as well as blood clots in the lungs and legs. These complications can be fatal.
Proper treatment improves your prognosis, and it increases life expectancy.
It may not be possible to slow the progression of Parkinsons, but you can work to overcome the obstacles and complications to have a better quality of life for as long as possible.
Parkinsons disease is not fatal. However, Parkinsons-related complications can shorten the lifespan of people diagnosed with the disease.
Having Parkinsons increases a persons risk for potentially life threatening complications, like experiencing:
Parkinsons often causes problems with daily activities. But very simple exercises and stretches may help you move around and walk more safely.
Young Onset Parkinsons : An Introduction
Although the average age to develop Parkinsons is around 60, young onset Parkinsons occurs in 5-10% of people diagnosed. 20% are under the age of 50. Some challenges in Parkinsons are universal, regardless of age, but there are a number of issues specific to younger people.
Generally, Parkinsons proceeds more slowly in younger people. While no two people are the same, someone whose onset age is 40 can expect to work for another 15-20 years on average. For someone with an onset age of 60, the average figure would be half that. These figures are based on the kinds of treatment available today. Future treatment will be even more effective in prolonging the productive life of people with Parkinsons.
Larry Gifford hosts a panel discussion on Living Well with Young Onset Parkinsons in May of 2020.
The following characteristics tend to be present in young onset Parkinsons:
- Young onset Parkinsons is less likely to lead to dementia and balance problems
- It is more likely to include focal dystonia, which is cramping or abnormal posturing of one part of the body.
- Younger people are more sensitive to the benefits of Parkinson medications, but they tend to experience the dyskinetic side effects of levodopa sooner than older people.
- They also tend to experience dose-related fluctuations at an earlier stage of the disease, including wearing off* and the on-off effect. See Parkinson Canada Information Sheet, Parkinsons Medications: What you need to know!

Diagnosis And Management Of Parkinsons Disease
There are no diagnostic tests for Parkinsons. X-rays, scans and blood tests may be used to rule out other conditions. For this reason, getting a diagnosis of Parkinsons may take some time.
No two people with Parkinsons disease will have exactly the same symptoms or treatment. Your doctor or neurologist can help you decide which treatments to use.
People can manage their Parkinsons disease symptoms through:
- seeing a Doctor who specialises in Parkinsons
- multidisciplinary therapy provided for example, by nurses, allied health professionals and counsellors
- deep brain stimulation surgery .
How Quickly Does Parkinsons Progress
Parkinsons disease is slowly progressive, and each case may be different. People may have symptoms for a year or two before a doctor makes a diagnosis.
The longer the symptoms are present, the easier it is to predict how a person with Parkinsons disease will do. In those with tremors and symptoms on one side of the body, the disease typically advances more slowly than in those without tremors who have symptoms that affect both sides of the body.
While the life expectancy of these patients reduces, people with Parkinsons disease usually function quite well for many years. However, these patients are at risk of suffering dementia, or from developing instability that could lead to falls.
This condition is by far the most treatable of all neurodegenerative disorders. A doctor may indicate treatment to help control symptoms.
For example, there are cases where people can function better in their daily lives five years later after they start medication.
The treatment includes exercise and changes in lifestyle. As well as medication with carbidopa-levodopa or dopamine agonists to improve body functionality.
There are surgical options as well, like deep brain stimulation, surgeons implant electrodes in the brain, and they receive electrical pulses, which reduces symptoms.
However, symptoms and responses to treatment vary from person to person, so it is not possible to accurately predict how Parkinsons disease will progress.

What Really Causes Parkinson’s Disease
Even though studies have pinpointed certain factors that influence the risk of Parkinson’s disease onset, most people with the disease have no family history, gene mutation, prior head injury, history of environmental toxin exposure, or history of using antidepressants, anti-anxiety medications, or sleeping pills. So, looking at the overall picture, it is nearly impossible to predict who will develop Parkinson’s disease. And if you have Parkinson’s disease, there is probably nothing you could have done to have prevented it.
Researchers are working to discover the combination of factors that causes Parkinson’s disease, in hopes of uncovering new ways to prevent, and perhaps treat, this chronic condition.
Surgery For People With Parkinsons Disease
Deep brain stimulation surgery is an option to treat Parkinsons disease symptoms, but it is not suitable for everyone. There are strict criteria and guidelines on who can be a candidate for surgery, and this is something that only your doctor and you can decide. Surgery may be considered early or late in the progression of Parkinsons. When performing deep-brain stimulation surgery, the surgeon places an electrode in the part of the brain most effected by Parkinsons disease. Electrical impulses are introduced to the brain, which has the effect of normalising the brains electrical activity reducing the symptoms of Parkinsons disease. The electrical impulse is introduced using a pacemaker-like device called a stimulator. Thalamotomy and pallidotomy are operations where the surgeon makes an incision on part of the brain. These surgeries aim to alleviate some forms of tremor or unusual movement, but they are rarely performed now.

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.
No One Definitive Cause Of Parkinsons
There are no biomarkers or objective screening tests that indicate one has Parkinsons. That said, medical experts have shown that a constellation of factors are linked to it.
Parkinsons causes are likely a blend of genetics and environmental or other unknown factors. About 10 to 20 percent of Parkinsons disease cases are linked to a genetic cause, says Ted Dawson, M.D., Ph.D., director of the Institute for Cell Engineering at Johns Hopkins. The types are either autosomal dominant or autosomal recessive .
But that leaves the majority of Parkinsons cases as idiopathic, which means unknown. We think its probably a combination of environmental exposure to toxins or pesticides and your genetic makeup, says Dawson.
Age. The biggest risk factor for developing Parkinsons is advancing age. The average age of onset is 60.
Gender. Men are more likely to develop Parkinsons disease than women.
Genetics. Individuals with a parent or sibling who is affected have approximately two times the chance of developing Parkinsons. Theres been an enormous amount of new information about genetics and new genes identified over the past 10 or 15 years that have opened up a greater understanding of the disease, says Dawson.

The Last Year Of Life In Parkinson’s Disease
The study also examined nearly 45,000 hospitalizations in people with terminal Parkinson’s, meaning their end-of-life period.
Of those with terminal PD, the most common reasons for being in the hospital were:
- Heart disease
- Lung disease that was not from an infection
Less common causes for hospitalization were problems related to the stomach or intestines, muscles, nervous system, or endocrine system .
It is not surprising that infection was the most common hospitalization before death, as people with Parkinson’s are vulnerable to developing a number of infections as a result of their disease. For example, bladder dysfunction in Parkinson’s increases a person’s risk of developing urinary tract infections, which can become life-threatening if not detected and treated promptly.
In addition, research suggests that aspiration pneumonia is 3.8 times more common in people with Parkinson’s as compared to the general population. It has also been consistently reported to be the main cause of death in people with Parkinson’s.
Aspiration pneumonia results from underlying swallowing difficulties, which leads to stomach contents being inhaled into the lungs. Immobilization and rigidity, which can impair phlegm removal, also contribute to the development of pneumonia in people with Parkinson’s.
Causes Of Parkinson’s Disease
Parkinsons occurs when neurons in the part of the brain that control body movement become impaired or die. These neurons are responsible for creating dopamine, an important brain chemical that is vital for normal body function.
With fewer of these neurons in the brain, insufficient dopamine is created. Scientists are still not sure what exactly causes these neurons to become impaired or die.
People with Parkinsons also lose nerve endings that produce norepinephrine, the chemical messenger of the sympathetic nervous system that controls heart rate and blood pressure. This could be why fatigue and a decrease in blood pressure regularly occur with people who have Parkinsons.
While there have been cases of the disease that appear to be hereditary and can be traced to specific genetic mutations, there isnt enough evidence yet to conclusively prove it is passed down from parents to their children.
Most cases of Parkinsons occur randomly, and researchers believe a combination of genetic and environmental factors are responsible.

Who Gets Parkinson’s Disease
About 1 million people in the United States have Parkinson’s disease, and both men and women can get it. Symptoms usually appear when someone is older than 50 and it becomes more common as people get older.
Many people wonder if you’re more likely to get Parkinson’s disease if you have a relative who has it. Although the role that heredity plays isn’t completely understood, we do know that if a close relative like a parent, brother, or sister has Parkinson’s, there is a greater chance of developing the disease. But Parkinson’s disease is not contagious. You can’t get it by simply being around someone who has it.
What Is Aggressive Parkinsons Disease
As written above, Parkinsons dementia aggression is that form of Parkinsons which makes the patient exhibit aggressive behavior. They vent out their aggression either verbally or physically, in the various forms that have been written above. Besides verbal and physical outbursts, PD Dementia patients are also prone to hallucinating caused by the medication administered. Hallucinations in PD Dementia patients primarily occur because of the effects of dopaminergic agents for motor symptoms.
Loss of dopamine neurons in the ventral tegmental area is one of the likeliest of all neuropathological causes as changes in serotonin and norepinephrine systems are not. For the uninitiated, the ventral tegmental area is the origin of the mesolimbic dopaminergic projection. Plenty of studies have gone into analyzing the cause behind the aggression in PD Dementia patients. Depression in PD Dementia patients has been identified due to changes in the medial frontal cortex and the anterior cingulate. Akinetic-rigid variants have been found in patients showing signs of major depression.

Incidence Of Parkinsons Disease
Its estimated that approximately four people per 1,000 in Australia have Parkinsons disease, with the incidence increasing to one in 100 over the age of 60. In Australia, there are approximately 80,000 people living with Parkinsons disease, with one in five of these people being diagnosed before the age of 50. In Victoria, more than 2,225 people are newly diagnosed with Parkinsons every year.
What Is Parkinson’s Disease
Parkinson’s disease is the second most common neurodegenerative disorder and the most common movement disorder. Characteristics of Parkinsons disease are progressive loss of muscle control, which leads to trembling of the limbs and head while at rest, stiffness, slowness, and impaired balance. As symptoms worsen, it may become difficult to walk, talk, and complete simple tasks.
The progression of Parkinson’s disease and the degree of impairment vary from person to person. Many people with Parkinson’s disease live long productive lives, whereas others become disabled much more quickly. Complications of Parkinsons such as falling-related injuries or pneumonia. However, studies of patent populations with and without Parkinsons Disease suggest the life expectancy for people with the disease is about the same as the general population.
Most people who develop Parkinson’s disease are 60 years of age or older. Since overall life expectancy is rising, the number of individuals with Parkinson’s disease will increase in the future. Adult-onset Parkinson’s disease is most common, but early-onset Parkinson’s disease , and juvenile-onset Parkinson’s disease can occur.
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 doctor to perfectly predict longevity. An older age and the presence of dementia are simply associated with an increased risk of dying.
What Are The Stages Of Parkinsons
Neurologists often use a system of stages, called the Hoehn and Yahr scale, to describe the progression of symptoms. These stages are:
- Stage 1 Symptoms are seen on one side of the body only.
- Stage 2 Symptoms are seen on both sides of the body. There’s no impairment of balance.
- Stage 3 Balance impairment has begun. In this mild to moderate stage of the disease, the person is still physically independent.
- Stage 4 This stage is marked by severe disability, but the person is still able to walk or stand unassisted.
- Stage 5 The person is wheelchair-bound or bedridden unless assisted.
