How Does One Get Parkinson’s Disease

What Are The Symptoms Present To Confirm Parkinsons Disease

Why do people get Parkinson’s?

In order to medically diagnose Parkinsons disease, a minimum of two to four symptoms must be present. The four main symptoms include-

  • Acute slowness of movement called Bradykinesia.
  • Stiffness or rigidity of the arms, legs and trunk.
  • Problems with maintaining body balance and posture which result in falls called postural instability.

How Does Alcohol Affect Parkinsons Medication

The interaction between Parkinsons medications and alcohol is a common topic on MyParkinsonsTeam. I miss my red wine and whiskey on occasion, one member wrote. I found that it just makes my meds stop working. Another member said, My husband has been told he shouldn’t drink with his meds.

Alcohol can exacerbate the side effects of one of the most common Parkinsons medications, levodopa/carbidopa. Many neurologists recommend avoiding alcohol while taking this drug.

I have to limit myself to one Scotch on the rocks now, a MyParkinsonsTeam member said. I used to have three or four, but the side effects are too bad. Another wrote, Never really a good idea to mix alcohol with meds.

Whether you decide to continue your current drinking habits, cut down, or eliminate alcohol altogether, its important to listen to your body and have open conversations about these topics with your neurologist.

If you find yourself drinking alcohol to cope with other issues, such as depression and anxiety, you may find that healthy practices such as physical activity can help. In addition, participating in activities such as tai chi, yoga, and meditation may help ease the symptoms and complications of PD.

What Role Do Genes Play

Your genes are like your body’s instruction book. So if you get a change in one of them, it can make your body work in a slightly different way. Sometimes, that means you’re more likely to get a certain disease.

There are several genetic mutations that can raise your risk for Parkinson’s, each by a little bit. They have a part in about 1 in 10 cases.

If you have one or more of these changes, it doesn’t mean you’ll get Parkinson’s. Some people will, but many won’t, and doctors don’t know why. It may have to do with other genes or something in your environment.

What Causes Parkinson’s Disease

Parkinsons disease occurs when nerve cells in the basal ganglia, an area of the brain that controls movement, become impaired and/or die. Normally, these nerve cells, or 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 fatigue, 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.

Youll need to be diligent about recording your dogs symptoms. Your vet will definitely be relying on your reports to see if their diagnosis is accurate. They will also test your dogs motor function by having them do certain physical exercises.

They may also have full blood work and x-ray scans done to rule out any other potential ailments.

Your vet may encourage that you get a second opinion too. Neurological diseases in dogs are somewhat difficult to diagnose.

Testing For Parkinsons Disease

There is no lab or imaging test that is recommended or definitive for Parkinsons disease. However, in 2011, the U.S. Food and Drug Administration approved an imaging scan called the DaTscan. This technique allows doctors to see detailed pictures of the brains dopamine system.

A DaTscan involves an injection of a small amount of a radioactive drug and a machine called a single-photon emission computed tomography scanner, similar to an MRI.

The drug binds to dopamine transmitters in the brain, showing where in the brain dopaminergic neurons are.

The results of a DaTscan cant show that you have Parkinsons, but they can help your doctor confirm a diagnosis or rule out a Parkinsons mimic.

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.

Deep Brain Stimulation For Parkinson’s: Am I A Candidate

Deep brain stimulation is not a cure, but it can relieve your symptoms from Parkinson’s disease when medications are not an option. Only you and your doctor can decide if this surgical procedure is right for you. You may be a candidate for deep brain stimulation if:

  • You have idiopathic Parkinson’s disease. Patients with atypical parkinsonism are not candidates.
  • You have good motor function and independence during your best “on” state when taking the drug Sinemet.

What is Parkinson’s 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.

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.

Environmental Factors And Exposures

Exposure to pesticides and a history of head injury have each been linked with PD, but the risks are modest. Never drinking caffeinated beverages is also associated with small increases in risk of developing PD.

Low concentrations of urate in the blood is associated with an increased risk of PD.

Drug-induced parkinsonism

Different medical drugs have been implicated in cases of parkinsonism. Drug-induced parkinsonism is normally reversible by stopping the offending agent. Drugs include:

How Is Parkinson’s Disease Diagnosed

Parkinsons Disease by tokarc18

Someone with the symptoms of Parkinson’s disease may be sent to see a neurologist, a doctor who specializes in the brain, nerves, and muscles. The neurologist may do some tests, including a brain scan and blood tests. These tests will not make the diagnosis of Parkinson’s disease, but the doctor will want to make sure that there is no other problem causing the symptoms. To diagnose Parkinson’s disease, the doctor relies on a person’s medical history, symptoms, and a physical exam.

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 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

Medications For People With Parkinsons Disease

Symptoms of Parkinsons disease result from the progressive degeneration of nerve cells in the brain and other organs such as the gut, which produce a neurotransmitter called dopamine. This causes a deficiency in the availability of dopamine, which is necessary for smooth and controlled movements. Medication therapy focuses on maximising the availability of dopamine in the brain. Medication regimes are individually tailored to your specific need. Parkinsons medications fit into one of the following broad categories:

  • levodopa dopamine replacement therapy
  • dopamine agonists mimic the action of dopamine
  • COMT inhibitors used along with levodopa. This medication blocks an enzyme known as COMT to prevent levodopa breaking down in the intestine, allowing more of it to reach the brain
  • anticholinergics block the effect of another brain chemical to rebalance its levels with dopamine
  • amantadine has anticholinergic properties and improves dopamine transmission
  • MAO type B inhibitors prevent the metabolism of dopamine within the brain.

What Is Parkinson’s Disease

Parkinsons disease is a brain disorder that affects a persons physical and mental abilities. As the disease slowly progresses, people begin to develop difficulties walking and talking. They will also experience behavioral changes, depression, loss of memory, sleep problems, and fatigue.

The exact cause of Parkinsons disease is not known, though scientists believe its a combination of genetic and environmental factors. The common thread between all people who have Parkinsons disease is a loss of neurons that create dopamine in the area of the brain known as the substantia nigra.

While there is no known cure, there are several treatment options that include lifestyle changes, medications, physical therapy, and surgery to help a person cope with Parkinsons.

Support For People With Parkinsons Disease

Impact of Falls and Parkinson’s 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.

How Will The Disease Affect My Life

Most people who have Parkinson√Ęs live a normal to a nearly normal lifespan, but the disease can be life changing.

For some people, treatment keeps the symptoms at bay, and they’re mostly mild. For others, the disease is much more serious and really limits what you’re able to do.

As it gets worse, it makes it harder and harder to do daily activities like getting out of bed, driving, or going to work. Even writing can seem like a tough task. And in later stages, it can cause dementia.

Even though Parkinson’s can have a big impact on your life, with the right treatment and help from your health care team, you can still enjoy the things you love. It’s important to reach out to family and friends for support. Learning to live with Parkinson’s means making sure you get the backing you need.

How Is Parkinsons Diagnosed

Doctors use your medical history and physical examination to diagnose Parkinson’s disease . No blood test, brain scan or other test can be used to make a definitive diagnosis of PD.

Researchers believe that in most people, Parkinson’s is caused by a combination of environmental and genetic factors. Certain environmental exposures, such as pesticides and head injury, are associated with an increased risk of PD. Still, most people have no clear exposure that doctors can point to as a straightforward cause. The same goes for genetics. Certain genetic mutations are linked to an increased risk of PD. But in the vast majority of people, Parkinsons is not directly related to a single genetic mutation. Learning more about the genetics of Parkinsons is one of our best chances to understand more about the disease and discover how to slow or stop its progression.

Aging is the greatest risk factor for Parkinsons, and the average age at diagnosis is 60. Still, some people get PD at 40 or younger.

Men are diagnosed with Parkinsons at a higher rate than women and whites more than other races. Researchers are studying these disparities to understand more about the disease and health care access and to improve inclusivity across care and research.

Aging is the greatest risk factor for Parkinsons, and the average age at diagnosis is 60. Still, some people get PD at 40 or younger.

The Michael J. Fox Foundation has made finding a test for Parkinsons disease one of our top priorities.

What Does Parkinson’s Do To The Brain

Speech Tips for Parkinson

Deep down in your brain, there’s an area called the substantia nigra, which is in the basal ganglia. Some of its cells make dopamine, a chemical that carries messages around your brain. When you need to scratch an itch or kick a ball, dopamine quickly carries a message to the nerve cell that controls that movement.

When that system is working well, your body moves smoothly and evenly. But when you have Parkinson’s, the cells of your substantia nigra start to die. There’s no replacing them, so your dopamine levels drop and you can’t fire off as many messages to control smooth body movements.

Early on, you won’t notice anything different. But as more and more cells die, you reach a tipping point where you start to have symptoms.

That may not be until 80% of the cells are gone, which is why you can have Parkinson’s for quite a while before you realize it.

How Does Parkinsons Disease Affect The Body

Recognising the signs

A combination of signs can help a doctor make an early diagnosis. If Parkinsons disease is diagnosed early, the chances of being able to treat and manage the condition are greater. Individual signs may not be an indication of Parkinsons disease. Some signs such as loss of smell could be caused by an infectious illness, or joint stiffness by conditions like arthritis.

Parkinsons is most commonly diagnosed with a very physical examination and assessment of a persons medical history. There are very specific markers for diagnosis which doctors use to assess for possible Parkinsons disease. These markers have a lot to do with a combination of very specific signs and symptoms and if recognised early enough, can be better managed.

1. Primary motor symptoms

2. Secondary motor symptoms

Other motor symptoms include:

Some individuals may also experience the following:

  • Hunched over / stooped posture – When standing, the body may begin to slouch or lean inwards, causing a hunched over appearance.
  • Impaired gross motor coordination
  • Impaired fine motor dexterity and motor coordination
  • Difficulties with swallowing or chewing
  • Cramping
  • Production of excess saliva and drooling
  • Sexual dysfunction
  • Dystonia
  • Akathisia

3. Non-motor symptoms

Symptoms that do not involve physical movement or coordination, and often precede motor problems, can include:

Symptoms are initially mild, even if they develop suddenly, and typically affect one side of the body at first.
