Are There Different Forms Of Parkinson’s Disease

Treatment For Atypical Parkinsonism Symptoms

Are there different types of Parkinson’s?

Because PD medication response is poor in these syndromes, treatment focuses on symptom management e.g. physical therapy for fall prevention, speech therapy to maximize communication, swallow therapy to prevent aspiration.

Other symptoms that can be addressed include dystonia, myoclonus, blood pressure dysfunction and urinary dysfunction.

Tips and takeaways:

  • Atypical parkinsonism is a very complicated group of diseases that are hard to diagnose. Sometimes a neurologist will change the diagnosis as new symptoms develop or become more apparent.
  • Despite the fact that these conditions typically do not respond well to medications for PD, many of the presenting symptoms can be addressed, so make sure to raise all of your concerns with your neurologist.

Parkinsonism Vs Parkinson’s Disease

Often confused as one and the same, Parkinsons disease is actually the most common kind of Parkinsonism, accounting for nearly 80% of all cases.2 PD is a progressive neurodegenerative disorder characterized by the same motor conditions as Parkinsonisms including tremor, rigidity, bradykinesia, and impaired balance. Other contributing causes of Parkinsonism include multiple system atrophy, progressive supranuclear palsy, and corticobasal degeneration. PD has no directly attributable cause or cure.

What Can I Expect If I Have This Condition

All cases of parkinsonism regardless of the specific condition involved slowed movements plus other related symptoms. What you can expect depends on the specific condition you have and what treatments if any that you receive. Your healthcare provider is the best person to tell you more about what you can expect if you have parkinsonism.

How long does parkinsonism last?

How long parkinsonism lasts depends on the specific condition. Nearly all conditions that fall under parkinsonism are life-long conditions. One condition that isn’t always a life-long problem is drug-induced parkinsonism.

Because parkinsonism includes so many different conditions, it’s best to talk to your healthcare provider about how long your condition will last. They can best explain what you can expect, including the likely timeline for how this condition will affect you.

Whats the outlook for this condition?

The outlook for parkinsonism depends on your condition, how severe it is, and whether or not it’s treatable. Many forms of parkinsonism aren’t deadly on their own but can contribute to deadly complications. An example of this is trouble swallowing, a common symptom of Parkinsons disease and other forms of parkinsonism, and how this increases your risk of developing pneumonia.

What Causes Parkinsons Disease

The most prominent signs and symptoms of Parkinsons disease occur 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 associated with the disease. Scientists still do not know what causes the neurons to die.

People with Parkinsons disease 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 Parkinsons, 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 position.

Many brain cells of people with Parkinsons disease 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 andLewy body dementia.

Whats The Difference Between Corticobasal Degeneration And Parkinsons

Parkinsons disease

The main difference between CBD and Parkinsons is that it usually starts on one side with the gradual loss of use of one hand or leg , and there may be little flicks of involuntary muscle jerks. Walking and balance difficulties usually occur later in CBD than in Parkinsons. Also, in CBD, a person may have trouble with purposeful movements, such as buttoning a shirt or cutting food.

This Explains Why Patients Can Experience Such Wildly Different Symptoms

Prior to this study, it was generally believed that there was only one type of Parkinsons disease. However, their work revealed that there are actually two major strains of the disease that can leave patients susceptible to a wide range of symptoms.

Until now, many people have viewed the disease as relatively homogenous and defined it based on the classical movement disorders, said researcher Per Borghammer. But at the same time, weve been puzzled about why there was such a big difference between patient symptoms. With this new knowledge, the different symptoms make more sense and this is also the perspective in which future research should be viewed.

What Are The Symptoms Of Parkinsonism

The key symptoms of parkinsonism are:

  • Slowed movements *.

*This symptom always happens with parkinsonism.

Other possible symptoms include:

  • Unstable posture or walking gait.
  • Flexed, hunched or stooped posture.
  • Freezing .

Condition-specific parkinsonian symptoms

Certain symptoms are more likely with a few conditions involving parkinsonism. Those conditions and the symptoms include:

  • Parkinsons disease: In addition to motor symptoms, this condition tends to involve several non-motor symptoms also. Many of these affect the unconscious processes of your body. Examples of this include constipation, loss of sense of smell and sleep problems.
  • Vascular parkinsonism: This condition tends to cause early balance and walking problems. It can also cause trouble speaking and swallowing . People with this also tend to have an unusual reflex when the bottom of their foot is touched a certain way .
  • Drug-induced parkinsonism: People with this tend to have parkinsonism-type symptoms equally on both sides of their body. With Parkinsons disease, the effects usually are worse on one side.
  • Toxin-induced parkinsonism: People with this have more severe “cogwheel rigidity,” which is a jerky pattern to their movements . Their muscles also are tense, causing slowed movements and trouble walking backward.
  • Juvenile parkinsonism: Experts usually suspect this type of parkinsonism once they rule out other causes because it is rare for this condition to happen to those under age 45.

The Oxford Parkinsons Disease Centre

We started writing about this topic in 2015, at the time there were a few papers detailing small scale studies about how Parkinsons affects people differently, but it was clear that more data was needed.

Fortunately, Parkinsons UK had recently renewed a grant from the Oxford Parkinsons Disease Centre to support the world-leading Discovery project. This included a study led by Dr Michele Hu with over 1,400 participants with and without Parkinsons that might shed more light on the subtyping situation.

We interviewed Dr Michele Hu, as well as two participants taking part in this pioneering project, in the Winter 2015 edition of our research magazine.

Weve discovered that there are differences between men and women who have Parkinsons. Men are more likely to experience problems with memory, postural hypotension and sleep problems. While women tend to experience more problems with posture and balance.

Even more excitingly, we think that we are beginning to be able to separate the people with Parkinsons in our study into distinct groups based on their symptoms and how the condition is progressing.

Dr Michele Hu, University of Oxford

It was a study that might open the door to separating Parkinsons out into groups. Something that, if it were made possible, could improve not only how we treat Parkinsons today but would also play a vital role in developing and testing new treatments that may slow or stop the condition.

Whats The Difference Between Multiple System Atrophy And Parkinsons

Are there different types of Parkinson’s Disease?

Parkinsons and MSA both affect the movement control system and the involuntary autonomic control system and early symptoms can make a differential diagnosis a challenge. MSA, however, tends to progress faster than Parkinsons balance problems and a stooped posture happen earlier and get worse more quickly with MSA and autonomic functions such as blood pressure, heart rate, breathing, sweating, bladder function, and sexual problems are more severe in people with MSA.

What Are The Symptoms Of Atypical Parkinsonian Disorders

Like classic Parkinsons disease, atypical Parkinsonian disorders cause muscle stiffness, tremor, and problems with walking/balance and fine motor coordination.

Patients with atypical Parkinsonism often have some degree of difficulty speaking or swallowing, and drooling can be a problem. Psychiatric disturbances such as agitation, anxiety or depression may also be part of the clinical picture.

Dementia with Lewy bodies can cause changes in attention or alertness over hours or days, often with long periods of sleep during the day. Visual hallucinations typically of small animals or children, or moving shadows in the periphery of the visual field are common in DLB. DLB is second only to Alzheimers disease as a cause of dementia in the elderly, and it most commonly affects patients in their 60s.

Patients with progressive supranuclear palsy may have difficulties with eye movements, particularly when looking downward, and with balance when descending stairs, for instance. Backward falls are common and may occur during the early course of the disease. PSP is not usually associated with tremor, unlike Parkinsons disease.

When Should I See My Healthcare Provider

You should see your healthcare provider as recommended or if you notice changes in your symptoms, especially if the symptoms start to interfere with your life and routine. You should also see your provider if you notice any changes in the effectiveness of your medication.

When should I go to ER?

Your healthcare provider can give you guidance and information on signs or symptoms that mean you need to go to the hospital or get medical attention. In general, you should get medical attention if you fall, especially when you lose consciousness or might have an injury to your head, neck, chest, back or abdomen.

A note from Cleveland Clinic

Parkinsonism is a term that covers a wide range of conditions that affect your ability to move and live independently. While these conditions all share certain similarities, they also can have major differences from each other. If youre diagnosed with parkinsonism, its important to talk to your healthcare provider about what condition you have , and what that diagnosis means for you. Not all parkinsonism conditions are the same, so understanding your specific case can make a big difference in managing it and how it affects your life.

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

17 Action Steps to improve Parkinson

You should be referred to a Parkinsons specialist for the diagnosis of any parkinsonism. They may wish to explore different things before giving you a diagnosis.

Your specialist will look at your medical history, ask you about your symptoms and do a medical examination.

Telling the difference between types of parkinsonism isnt always easy, for the following reasons:

  • The first symptoms of the different forms of parkinsonism are so similar.
  • In many cases, parkinsonism develops gradually. Symptoms that allow your doctor to make a specific diagnosis may only appear as your condition progresses.
  • Everyone with parkinsonism is different and has different symptoms.

Find out more: see our information on symptoms of Parkinsons, and diagnosing Parkinsons.

One of the most useful tests to find out what sort of parkinsonism you may have is to see how you respond to treatment.

If your specialist thinks you have idiopathic Parkinsons, theyll expect you to have a good response to Parkinsons drugs such as levodopa . A good response means that your symptoms will improve. Sometimes, it will only be clear that youve responded to medication when the drug is reduced or stopped, and your symptoms become more obvious again.

If you dont have any response to Parkinsons medication, your specialist will have to look again at your diagnosis.

Although not routinely available, your specialist may wish to carry out some of the tests below.

Current tests available include:

Possible Causes Of Parkinsonism

For many types of parkinsonism, the exact cause isnt known. Genetic and environmental factors are both believed to play a role.

Parkinsons disease has been linked to exposure to pesticides and herbicides, as well as living close to industrial plants. Some genes are also associated with an elevated risk of developing Parkinsons.

Conditions that cause brain damage, like traumatic injuries, tumors, and exposure to certain toxins, are also potentially contributing factors to the development of parkinsonism.

What Is The Difference Between Parkinsonism And Parkinsons Disease

Parkinsonism refers to several conditions including Parkinsons disease that have similar symptoms and features. However, Parkinsons disease makes up about 80% of all cases of parkinsonism, making it the most common form by far. Other conditions that fall under the term parkinsonism include multiple system atrophy or corticobasal degeneration.

Another key difference is that parkinsonism can happen for reasons that are treatable or even curable. Some of the causes of parkinsonism can also go away on their own and only need treatment for some of their symptoms.

What Are The Different Forms Of Parkinsonism

There are three main forms of parkinsonism, as well as other related conditions.

Most people with parkinsonism have idiopathic Parkinsons disease, also known as Parkinsons. Idiopathic means the cause is unknown.

The most common symptoms of idiopathic Parkinsons are tremor, rigidity and slowness of movement.

Vascular parkinsonism affects people with restricted blood supply to the brain. Sometimes people who have had a mild stroke may develop this form of parkinsonism.

Common symptoms include problems with memory, sleep, mood and movement.

Some drugs can cause parkinsonism.

Neuroleptic drugs , which block the action of the chemical dopamine in the brain, are thought to be the biggest cause of drug-induced parkinsonism.

The symptoms of drug-induced parkinsonism tend to stay the same only in rare cases do they progress in the way that Parkinsons symptoms do.

Drug-induced parkinsonism only affects a small number of people, and most will recover within months and often within days or weeks of stopping the drug thats causing it.

Incidence Of Parkinsons Disease

What are the different stages of Parkinson’s 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.

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.

Parkinsons Disease Vs Parkinsonism: Whats The Difference

The recent death of President George H.W. Bush, who had been diagnosed with vascular parkinsonism towards the end of his life, placed this disease in the media limelight. Generally, there is a lot of confusion about Parkinsons disease and parkinsonism and many of you have asked me to clarify this distinction.

How Is Parkinson’s Disease Diagnosed

Diagnosis is difficult at every stage of the disease, but particularly in the early stages. No single test can provide a diagnosis. A diagnosis will likely involve physical and neurological examinations, conducted over time to assess changes in reflexes, coordination, muscle strength, and mental function. Your doctor might also see how you respond to medicine.

You may need to have brain imaging tests to rule out other conditions that might be causing your symptoms. Such tests could include MRI and CT scans and possibly some other types of scans. Blood tests may also be done to exclude other illnesses.

Causes Of Parkinson’s Disease

Parkinsons Disease: Types, Symptoms, Causes, Diagnosis And Treatment

Parkinson’s 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 Parkinson’s disease.

Exactly what causes the loss of nerve cells is unclear. Most experts think that a combination of genetic and environmental factors is responsible.
