What Is The Main Cause Of Parkinson Disease

What Are The Symptoms Of Parkinson’s Disease

What causes Parkinson’s disease?

The main symptoms of Parkinson’s disease are:

  • tremor or shaking, often when resting or tired. It usually begins in one arm or hand
  • muscle rigidity or stiffness, which can limit movement and may be painful
  • slowing of movement, which may lead to periods of freezing and small shuffling steps
  • stooped posture and balance problems

The symptoms of Parkinson’s disease vary from person to person as well as over time. Some people also experience:

  • loss of unconscious movements, such as blinking and smiling
  • difficulties with handwriting
  • drop in blood pressure leading to dizziness
  • difficulty swallowing
  • sweating

Many of the symptoms of Parkinson’s disease could be caused by other conditions. For example, stooped posture could be caused by osteoporosis. But if you are worried by your symptoms, it is a good idea to see your doctor.

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.

Pesticide And Herbicide Exposure

A strong link has been shown between PD and exposure to pesticides and herbicides. We need more Parkinsons-specific research to better understand what causes PD and to work to prevent it and help eliminate the risk of getting the disease, when it comes to all environmental risk factors and whether genetics can cause an increased risk in developing Parkinsons.

One herbicide that has been linked to Parkinsons is paraquat, a widely used commercial herbicide in the U.S. that is banned in 32 countries, including the European Union and China. The Parkinsons Foundation, along with the Unified Parkinsons Advocacy Council, signed two letters to the U.S. Environmental Protection Agency encouraging them to cancel the registration of paraquat based on strong scientific research linking the herbicide to Parkinsons disease. In October 2020, the EPA re-approved paraquat for use in the U.S. Without additional action, paraquat will remain legal for sale and use in the U.S. for the next 15 years.

What Are The Surgical Treatments For Parkinsons Disease

Parkinsons Disease Symptoms

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.

Clinical History And Testing

Diagnostic tests can be used to establish some features of the condition and distinguish them from symptoms of other conditions. Diagnosis may include taking the person’s , a physical exam, assessment of neurological function, testing to rule out conditions that may cause similar symptoms, brain imaging, to assess cognitive function,, or myocardial scintigraphy. Laboratory testing can rule out other conditions that can cause similar symptoms, such as abnormal , , , or vitamin deficiencies that may cause symptoms similar to dementia.

Typical dementia screening tests used are the and the . The pattern of cognitive impairment in DLB is distinct from other dementias, such as AD the MMSE mainly tests for the memory and language impairments more commonly seen in those other dementias and may be less suited for assessing cognition in the Lewy body dementias, where testing of visuospatial and executive function is indicated. The MoCA may be better suited to assessing cognitive function in DLB, and the scale and the may help understand cognitive decline relative to fluctuations in DLB. For tests of attention, , , and can be used for simple screening, and the Revised Digit Symbol Subtest of the may show defects in attention that are characteristic of DLB. The , and are used for evaluation of executive function, and there are many other screening instruments available.

What Medications Are Used To Treat Parkinsons Disease

Medications are the main treatment method for patients with Parkinsons disease. Your doctor will work closely with you to develop a treatment plan best suited for you based on the severity of your disease at the time of diagnosis, side effects of the drug class and success or failure of symptom control of the medications you try.

Medications combat Parkinsons disease by:

  • Helping nerve cells in the brain make dopamine.
  • Mimicking the effects of dopamine in the brain.
  • Blocking an enzyme that breaks down dopamine in the brain.
  • Reducing some specific symptoms of Parkinsons disease.

Levodopa: Levodopa is a main treatment for the slowness of movement, tremor, and stiffness symptoms of Parkinsons disease. Nerve cells use levodopa to make dopamine, which replenishes the low amount found in the brain of persons with Parkinsons disease. Levodopa is usually taken with carbidopa to allow more levodopa to reach the brain and to prevent or reduce the nausea and vomiting, low blood pressure and other side effects of levodopa. Sinemet® is available in an immediate release formula and a long-acting, controlled release formula. Rytary® is a newer version of levodopa/carbidopa that is a longer-acting capsule. The newest addition is Inbrija®, which is inhaled levodopa. It is used by people already taking regular carbidopa/levodopa for when they have off episodes .

General Approach To Management

The primary goal in the management of PD is to treat the symptomatic motor and nonmotor features of the disorder, with the objective of improving the patients overall quality of life. Appropriate management requires an initial evaluation and diagnosis by a multidisciplinary team consisting of neurologists, primary care practitioners, nurses, physical therapists, social workers, and pharmacists., It is also important that the patient and his or her family have input into management decisions.

Effective management should include a combination of nonpharmacological and pharmacological strategies to maximize clinical outcomes. To date, therapies that slow the progression of PD or provide a neuroprotective effect have not been identified., Current research has focused on identifying biomarkers that may be useful in the diagnosis of early disease and on developing future disease-modifying interventions.,

Two Areas In Which Parkinsons Disease May Bring About Death

Parkinson’s Disease | What Causes Parkinson’s Disease

I. Falls

PD patients are at an increased risk of falling and bad falls can lead to death. This usually occurs as a complication of a fall that requires hospitalization, particularly if it involves surgery. While most people do not fracture their hips when they fall, some do, and hip surgery, while routine, is still major surgery. It carries the risk of infection, delirium related to pain medications and anesthesia, heart failure, pneumonia, blood clots in the legs that then go to the lungs, and general weakness from immobility. Hip fractures are probably the main cause for death for those who fall, but people can fracture other bones and require surgery. They may fracture their ribs, which leads to reduced coughing, because of the pain, and an increased risk of lung infections . It is surprisingly uncommon for Parkinsons Disease patients to die from brain injuries related to falls, but it still may occur.

II. Pneumonia

PD patients also may develop pneumonias completely unrelated to difficulties with swallowing, just like their non-PD friends and relatives.

Eat Fresh Raw Vegetables

If you needed more reasons to eat your vegetables, this should be the clincher. Studies show that increased amounts of the B vitamin folic acid, found primarily in vegetables, can significantly reduce the risk of Parkinsons.

The best sources of folic acid are simultaneously some of the healthiest foods on the planet, namely dark green vegetables like broccoli, spinach, collard greens, brussels sprouts, asparagus and okra all of which can be grown in your backyard! This B vitamin can also be found in avocado, legumes and lentils.

How Is A Diagnosis Made

Because other conditions and medications mimic the symptoms of PD, getting an accurate diagnosis from a physician is important. No single test can confirm a diagnosis of PD, because the symptoms vary from person to person. A thorough history and physical exam should be enough for a diagnosis to be made. Other conditions that have Parkinsons-like symptoms include Parkinsons plus, essential tremor, progressive supranuclear palsy, multi-system atrophy, dystonia, and normal pressure hydrocephalus.

How Does Environment Come Into It

Your environment is a hard one to pin down. Partly, that’s because it covers a lot of ground. It’s everything that’s not your genes, which could mean where you live, what you eat, chemicals you’ve come into contact with, and more.

Not only that, but it could take years for the effects from something in your environment to show up. So far, doctors have a lot of clues but no smoking gun. So you could have people who live or work in an area around chemicals tied to Parkinson’s, but many of them don’t get it.

Some research shows links between Parkinson’s and:

  • Agent Orange, a chemical used to destroy trees and crops in the Vietnam War.
  • Certain chemicals used in farming, such as insecticides, herbicides, and fungicides.
  • Some metals and chemicals used in factories, such as manganese, lead, and trichlorethylene .

These can come into play based on where you live, what you do for work, or if you served in the military. Sometimes, these chemicals seep into well water, so that’s one more way they can affect you.

What Are The Different Stages Of Parkinsons Disease

Parkinsonâs 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 stage

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.

Mid stage

Mid-late stage

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.

Advanced stage

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 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:

    Some studies have suggested that Parkinsons disease is caused when the brain cells responsible for producing dopamine stop working or die completely. It typically leads to motor symptoms that slow your body down and make everyday activities more challenging.

    According to the NHS, the three main symptoms of Parkinsons disease are:

    • Involuntary shaking of particular parts of the body
    • Slow movement
    • Stiff and inflexible muscles.

    A person with Parkinsons disease can also experience a wide range of other physical and psychological symptoms.

    These include:

    • Balance problems
    • Loss of sense of smell
    • Problems sleeping
    • Memory problems.

    The cause of the disease is unknown, says doctor Lynda Nwabuobi, assistant professor of clinical neurology at Weill Cornell Parkinsons Disease and Movement Disorders Institute. She said: We dont have one cause, but based on what we have studied and learned, we know Parkinsons disease happens due to an interaction between the ageing brain, your genetics, and your environment.

    What You Can Do

    As of 2021, there is no definite cure for Parkinsons disease. There is also no definite known cause. Its likely due to a combination of an individuals susceptibility and environmental factors. Most cases of Parkinsons disease happen without a genetic link.

    According to research published in 2012, only report having a family member with the disease. Many toxins are suspected and have been studied, but no single substance can be reliably linked to Parkinsons.

    However, research is ongoing. Its estimated that

    How Does The Parkinsons Disease Progress Over Time

    Although slow, Parkinsons disease is progressive in nature where the condition keeps worsening at every stage.

    In the initial stage, the symptoms are seen to be mild in nature. The symptoms do not really interfere with the daily tasks and the lifestyle of the patient. The tremors and problems with balance, movement starts from one side of the body.

    The next phase is characterized by moderate form of the symptoms which are distinctively noticed by people. The muscles become stiff and posture is likely to be irregular. Exercise may be recommended by the doctor to ease out the stiffness. However, balance of the patient is not much impaired.

    The next stage is considered to be the turning point of the symptoms because the patient may start to lose control over his balance of the posture. He may also experience decreased reflex and is more prone to fall down while his movements become slower. In this stage, occupational therapy is required to help the patient with the stiffness and fine motor abilities.

    In the second last stage the patient may not even be able to stand without help. The patient should not live alone because daily activities cannot be done independently. It is extremely important to have the assistance if a care giver at this stage.
