Stiffness And Slow Movement
Parkinsons disease mainly affects adults older than 60. You may feel stiff and a little slow to get going in the morning at this stage of your life. This is a completely normal development in many healthy people. The difference with PD is that the stiffness and slowness it causes dont go away as you get up and start your day.
Stiffness of the limbs and slow movement appear early on with PD. These symptoms are caused by the impairment of the neurons that control movement. A person with PD will notice jerkier motions and move in a more uncoordinated pattern than before. Eventually, a person may develop the characteristic shuffling gait.
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 having smoked cigarettes, and never drinking caffeinated beverages, are 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.
Different medical drugs have been implicated in cases of parkinsonism. Drug-induced parkinsonism is normally reversible by stopping the offending agent. Drugs include:
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.

In The Loop: Staying Ahead Of Parkinsons Disease One Ping Pong Game At A Time
Since being diagnosed with Parkinson’s disease, Steve Grinnell has worked hard to stay active, stepping up his table tennis game and, thanks to co-workers, testing his skills outside his home.
Four years ago, Steve Grinnell’s life was forever changed when doctors at Mayo Clinic in Rochester diagnosed him with early-onset Parkinson’s disease. Since that time, the progressive nervous system disorder has begun to take a toll on Steve and his family, just as it does on the millions of other Americans living with the disease. “It has greatly diminished his quality of life, leaving him with tremors, physical exhaustion, impaired balance, troubled grasping things with his right hand, slow right-arm movement and problems sleeping,” the Rochester Post-Bulletin recently reported. “That’s to name just a few of his symptoms.”
Reading that, one might assume the disorder is winning. And to Steve, sometimes it feels like it is. But much of the time, he tells us he also feels like he’s staying one step ahead of the disease by staying as physically active as possible. “Parkinson’s presents such a conundrum because it wears you down physically, and yet exercise is so valuable,” Steve says. “My legs, feet and right arm are always cramping, so it takes mental effort to get moving.”
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.

Diagnosis Of Parkinsons Disease
A number of disorders can cause symptoms similar to those of Parkinson’s disease. People with Parkinson’s-like symptoms that result from other causes are sometimes said to have parkinsonism. While these disorders initially may be misdiagnosed as Parkinson’s, certain medical tests, as well as response to drug treatment, may help to distinguish them from Parkinson’s. Since many other diseases have similar features but require different treatments, it is important to make an exact diagnosis as soon as possible.
There are currently no blood or laboratory tests to diagnose nongenetic cases of Parkinson’s disease. Diagnosis is based on a person’s medical history and a neurological examination. Improvement after initiating medication is another important hallmark of Parkinson’s disease.
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.

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.
Getting Care At Any Stage
Although the different scales are meant to measure the progression of Parkinsons disease and the response to medication and treatment, some patients may never progress to stage 5, and not everyone with Parkinsons will spend the same amount of time in each stage. Some people are diagnosed with Parkinsons when they are young and remain in the early stages for several years. Others may skip stages, or their progression to end-stage Parkinsons may be more rapid. It is also possible to experience symptoms like tremors but not have any balance issues.
No matter where you are in your Parkinsons journeywhether youre at stage 1 or stage 5know that youre alone. At PLM, there is a community of over 30,000 Parkinsons patients who know what youre going through. Join the conversation to connect with others who are like you and can support you through your illness.

Is Surgery An Option
If medicine doesnât work well enough, your doctor may suggest deep brain stimulation . In DBS, your doctor implants electrodes deep in the brain. A device connected to them delivers electrical pulses. Those pulses can help control the tremors caused by Parkinson’s.
In the past, doctors sometimes used other operations to damage the brain in ways to help with movement symptoms. But they rarely use those surgeries now.

Parkinsons disease is a neurodegenerative disorder that affects predominantly dopamine-producing neurons in a specific area of the brain called substantia nigra. 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. What are the four cardinal signs of Parkinsons disease to spot?
In a study published in the National Library of Health, the description of all four cardinal signs of Parkinsons disease was analysed.
Although individual signs of Parkinsons disease most frequently tremor have been described since ancient times, the first systematic description of the disease is attributed to James Parkinson in 1817, noted the study.
It added: We present evidence that not only individual signs, but the disease itself with all four cardinal signs were first described in 1690.
The study found the four cardinal symptoms being major warnings for Parkinsons disease include tremor, bradykinesia, rigor and postural instability.

Complementary And Alternative Therapies
Some people with Parkinson’s disease find complementary therapies help them feel better. Many complementary treatments and therapies claim to ease the symptoms of Parkinson’s disease.
However, there’s no clinical evidence they’re effective in controlling the symptoms of Parkinson’s disease.
Most people think complementary treatments have no harmful effects. However, some can be harmful and they shouldn’t be used instead of the medicines prescribed by your doctor.
Some types of herbal remedies, such as St John’s wort, can interact unpredictably if taken with some types of medication used to treat Parkinson’s disease.
If you’re considering using an alternative treatment along with your prescribed medicines, check with your care team first.
Treatment For Primary Motor Symptoms In Parkinsons Disease
Although there are currently no medications that can cure or slow the progression of PD, there are several treatments that can help relieve symptoms, including the primary motor symptoms of PD. Treatment approaches include medications, surgery , and complementary or alternative medicine.
Several medications are available that can help relieve the primary motor symptoms. Initial therapy is usually levodopa , dopamine agonists, and/or monoamine oxidase-B inhibitors. The combination of levodopa and carbidopa is the most effective treatment available for the management of motor symptoms of PD. However, it can cause a side effect known as dyskinesia, which are abnormal involuntary movements. Dopamine agonists are less effective on the motor symptoms of PD but have a lower rate of causing dyskinesia, although they have other side effects. MAO-B inhibitors are less effective than levodopa or dopamine agonists, however they have fewer side effects. Choice of therapy should be customized to the individual patient with an understanding of the risks and benefits of each class of medication.3

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.

How Is Parkinsons Disease Diagnosed
Diagnosing Parkinsons disease is sometimes difficult, since early symptoms can mimic other disorders and there are no specific blood or other laboratory tests to diagnose the disease. Imaging tests, such as CT or MRI scans, may be used to rule out other disorders that cause similar symptoms.
To diagnose Parkinsons disease, you will be asked about your medical history and family history of neurologic disorders as well as your current symptoms, medications and possible exposure to toxins. Your doctor will look for signs of tremor and muscle rigidity, watch you walk, check your posture and coordination and look for slowness of movement.
If you think you may have Parkinsons disease, you should probably see a neurologist, preferably a movement disorders-trained neurologist. The treatment decisions made early in the illness can affect the long-term success of the treatment.

Software Analyzes Facial Expressions Hand Movements
Smiles are not the only behaviors that Hoque and his lab can analyze for early symptoms of Parkinsons disease or related disorders.
In collaboration with Ray Dorseya leading expert in Parkinsons disease and the David M. Levy Professor of Neurology at Rochesterand the Universitys Morris K. Udall Parkinson Disease Research Center, the researchers have developed a five-pronged test that neurologists could administer to patients sitting in front of their computer webcams hundreds of miles away.
This could be transformative for patients who are quarantined, immobile, or living in underdeveloped areas where access to a neurologist is limited, Hoque says.
In addition to making the biggest smile, and alternating it with a neutral expression three times, patients taking the test are also asked to:
- Read aloud a complex written sentence
- Touch their index finger to their thumb 10 times as quickly as possible
- Make the most disgusted look possible, alternating with a neutral expression, three times
- Raise their eyebrows as high as possible, then lower them as far as they can, three times slowly
Using machine learning algorithms, the computer program showswithin minutesa percentage likelihood from each of the tests whether the patient is showing symptoms of Parkinsons disease or related disorders.
Hence the importance of testing other expressions and movements, according to Ali, a former postdoctoral associate in Hoques lab who now is an associate data scientist at Sysco.
Progress Toward Fda Approval
It will be a while yet, however, before Hoque and his researchers can start seeking permission to analyze peoples selfies, or even before neurologists can deploy the five-pronged test that the researchers have developed.
An algorithm will never be 100 percent accurate, Hoque says. What if it makes a mistake? We want to be very careful and follow guidance from the FDA if we want anybody from any part of the world to try this and get an assessment.
Moreover, there is a whole family of movement disorders that are closely related to Parkinsons disease, including ataxia, Huntingtons disease, progressive supranuclear palsy, and multiple dystrophy.
They all share similar symptoms of tremor, but the tremors are very different in nature, Hoque says. However, even expert neurologists find it very, very difficult to distinguish among them.
The researchers have made great progress in detecting Parkinsons disease by automatically analyzing expressions, voice and motor movements. Yet further work is needed to develop algorithms to differentiate how these involuntary tremors differ across other movement disorders, including Ataxia and Huntingtons.
We cant tell that just yet, Hoque says. But we are in a pursuit of differentiating those tremors using AI to prevent the potential harm of misdiagnosis while maximizing benefit.

What Lifestyle Changes Can I Make To Ease Parkinsons Symptoms
Exercise: 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.
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.
