Different Types Of Symptoms
One of the first attempts to separate Parkinsons into different subtypes based on symptoms experienced came from the Oxford Parkinsons Disease Centre a couple of years later. In a condition where every individual is different, this pioneering study had discovered 5 potential subtypes by analysing both the movement and non-movement symptoms that 769 people with Parkinsons experienced. You can read about these types in a previous blog.
In the discussion of this paper, the researchers were keen to point out that they didnt yet know if these subtypes would predict the progression and types of symptoms people would develop. However, other studies were starting to publish the first information about what symptoms may be linked to faster progression of Parkinsons.
One such study was lead by a Canadian team and analysed data from 113 people with Parkinsons. In this study, the researchers suggested that early symptoms of mild cognitive impairment, blood-pressure related dizziness on standing, and REM-sleep behaviour disorder may identify a subgroup of people with a more rapidly progressing condition.
What Is The Outlook For Persons With Parkinsons Disease
Although there is no cure or absolute evidence of ways to prevent Parkinsons disease, scientists are working hard to learn more about the disease and find innovative ways to better manage it, prevent it from progressing and ultimately curing it.
Currently, you and your healthcare teams efforts are focused on medical management of your symptoms along with general health and lifestyle improvement recommendations . By identifying individual symptoms and adjusting the course of action based on changes in symptoms, most people with Parkinsons disease can live fulfilling lives.
The future is hopeful. Some of the research underway includes:
- Using stem cells to produce new neurons, which would produce dopamine.
- Producing a dopamine-producing enzyme that is delivered to a gene in the brain that controls movement.
- Using a naturally occurring human protein glial cell-line derived neurotrophic factor, GDNF to protect dopamine-releasing nerve cells.
Many other investigations are underway too. Much has been learned, much progress has been made and additional discoveries are likely to come.
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
Other symptoms may include depression and other emotional changes difficulty swallowing, chewing, and speaking urinary problems or constipation skin problems and sleep disruptions.
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.

Parkinsons Dementia Vs Alzheimers Dementia
According to experts, Parkinsons dementia can cause impaired physical activity and impacts motor skills. Two neurotransmitters called dopamine and serotonin tend to be damaged by Parkinsons.
In addition to causing issues with movement and coordination, this form of dementia can also cause a slower thought process and memory problems. This is usually less pronounced however, until the later stages of the disease.
With Alzheimers, two types of proteins in the brain, tangles and plaques , accumulate and kill brain cells. This Alzheimers-induced dementia affects memory, clear thinking, language skills, and orientation. It reduces comprehension, learning capacity, and judgement. Storing new information and memory retrieval are impacted more than motor skills.
Distinguishing between these neurodegenerative conditions is important to determine the best treatment approach. Medications for one of condition might create problems when given to a patient with the other condition.
Two Types Of Parkinsons Disease
By Amanda Butas 9 am on July 8, 2019
Parkinsons symptoms develop when approximately 80 percent of the neurons that produce dopamine become damaged or die. Statistics indicate approximately one million adults in the United States live with the debilitating disorder. While many people have heard about Parkinsons, few may realize there are two types of the disease.

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
Whats The Difference Between Multiple System Atrophy And Parkinsons
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.

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.
Can Parkinsons Disease Be Prevented
Unfortunately, no. Parkinsons disease is long-term disease that worsens over time. Although there is no way to prevent or cure the disease , medications may significantly relieve your symptoms. In some patients especially those with later-stage disease, surgery to improve symptoms may be an option.

Why Pain Occurs In Parkinsons Disease
Parkinsons is a brain disease that is caused by the death of cells responsible for dopamine production. Dopamine is a chemical messenger that plays an important role in body movement. It is mainly concentrated in the substantia nigra part of the brain. When its production ceased in the brain, the body experience abnormal movement .
In addition to the substantia nigra, dopamine can also be found in other regions of the brain like thalamus, basal ganglia, insula, and anterior cingulate cortex. These regions are typically associated with pain perception. The presence of dopamine in these areas suggests that, in addition to its main role in the movement, dopamine may also involve in the modulation of pain sensation within the brain .
In fact, recent research shows that a low level of dopamine in some of these regions contribute to develop pain in the body. This evidence strongly suggests that apart from motor symptoms, a low level of dopamine also causes pain. And this could be the likely reason why people with Parkinsons feel pain in their body .
But most clinicians think that Parkinsons disease symptoms are the actual cause of pain. The pain is directly linked to the intensity of symptoms, the more strong the symptom the more pain will be felt .
For example, rigidity is one of the major symptoms in Parkinsons patients. Those patients who have high rigidity are tended to experience more pain than those who have less.
Whats The Difference Between Progressive Supranuclear Palsy And Parkinsons
People with PSP generally progress more rapidly than people with Parkinsons. A person with Parkinsons tends to lean forward while a person with PSP tends to lean backward. Tremors are common in people with Parkinsons and rare in people with PSP. Speech and swallowing abnormalities are more severe and show up sooner in those living with PSP.

Understanding The Two Forms Of Parkinsons Disease
By Gleria Anderson 9 am on July 18, 2019
Approximately 50,000 new cases of Parkinsons are diagnosed every year. The disorder is more prevalent in men, but the risk of developing the disease increases in both genders with age. The majority of people dont realize theres more than one form of the disease.
Many seniors in the early stages of Parkinsons are able to live on their own, but they may need a bit of help with everyday activities, such as exercising and preparing nutritious meals. Aging adults who require assistance with the tasks of daily living can benefit from reliable home care services.Families trust Home Care Assistance to provide the high-quality care their elderly loved ones need and deserve. Our caregivers are trained to help seniors prevent and manage serious illnesses and encourage them to make healthier decisions as they age.
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.

Tracking Parkinsons Joins Forces With The Oxford Parkinsons Disease Centre
In 2018, Tracking Parkinsons was the largest, in-depth study of the condition ever attempted, a title it still holds to this date. The project had been running for 5 years and had data from 2,600 participants across 70 hospitals in the UK.
Using sophisticated data analysis on the types of motor and non-motor symptoms people had when joining the research studies, the teams identified 4 possible subtypes of Parkinsons:
Subtype I:Prominent tremor on one side, an average level of non-motor symptoms and responding poorly to levodopa.
Subtype II: Mild motor and non-motor symptoms.
Subtype III: Severe movement symptoms, poor psychological well-being and poor sleep.
Subtype IIII: Symmetrical motor symptoms , poor sense of smell, low blood pressure, memory problems and responding poorly to levodopa .
Adapted from Developing and validating Parkinsons disease subtypes and their motor and cognitive progression
And for the first time, researchers linked these subtypes to progression rates. Those in the last subtype were likely to experience the fastest progression of their symptoms, while the middle two progressed at an average rate, and those in the first seemed to have the slowest progressing form of the condition.
Multiple System Atrophy Formerly Called Shy
As predicted by the name of this parkinsonism, multiple system atrophy affects multiple systems of the body. It affects both the motor skills movement system and the involuntary system of the body. Though the symptoms can often be treated with medications, there is no cure. In addition, there are no drugs that are able to slow the progress of MSA.

Medicines For Parkinson’s Disease
Medicines prescribed for Parkinson’s include:
- Drugs that increase the level of dopamine in the brain
- Drugs that affect other brain chemicals in the body
- Drugs that help control nonmotor symptoms
The main therapy for Parkinson’s is levodopa, also called L-dopa. Nerve cells use levodopa to make dopamine to replenish the brain’s dwindling supply. Usually, people take levodopa along with another medication called carbidopa. Carbidopa prevents or reduces some of the side effects of levodopa therapysuch as nausea, vomiting, low blood pressure, and restlessnessand reduces the amount of levodopa needed to improve symptoms.
People with Parkinson’s should never stop taking levodopa without telling their doctor. Suddenly stopping the drug may have serious side effects, such as being unable to move or having difficulty breathing.
Other medicines used to treat Parkinsons symptoms include:
- Dopamine agonists to mimic the role of dopamine in the brain
- MAO-B inhibitors to slow down an enzyme that breaks down dopamine in the brain
- COMT inhibitors to help break down dopamine
- Amantadine, an old antiviral drug, to reduce involuntary movements
- Anticholinergic drugs to reduce tremors and muscle rigidity
What Are Atypical Parkinsonian Disorders
Atypical Parkinsonian disorders are progressive diseases that present with some of the signs and symptoms of Parkinsons disease, but that generally do not respond well to drug treatment with levodopa. They are associated with abnormal protein buildup within brain cells.
The term refers to several conditions, each affecting particular parts of the brain and showing a characteristic course:
- Dementia with Lewy bodies, characterized by an abnormal accumulation of alpha-synuclein protein in brain cells
- Progressive supranuclear palsy, involving tau protein buildup affecting the frontal lobes, brainstem, cerebellum and substantia nigra
- Multiple system atrophy, another synucleinopathy that affects the autonomic nervous system , substantia nigra and at times the cerebellum
- Corticobasal syndrome, a rare tauopathy that typically affects one side of the body more than the other and makes it difficult for patients to see and navigate through space

Pathogenesis Of Parkinsons Disease
A number of mechanisms have been implicated in PD pathogenesis, with -synuclein aggregation central to the development of the disease. Multiple other processes are thought to be involved, with several studies suggesting that abnormal protein clearance, mitochondrial dysfunction, and neuroinflammation play a role in the onset and progression of PD. However, the relationship between these pathways remains unclear.
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.
