Whats The Difference Between Dementia With Lewy Bodies And Parkinsons
In dementia with Lewy bodies, dementia always appears first. There can also be changes in alertness as well as visual hallucinations. However, because of the presence of Lewy bodies throughout the entire brain, characteristics of this disease not only include cognitive characteristics, but also physical, sleep, and behavioral changes. As the disease progresses, the motor symptoms common to Parkinsons such as tremor, slowness, stiffness, and walking and balance problems will appear.

How Parkinsonism Differs From Parkinsons Disease
Parkinsons disease is one of many types of parkinsonism. Its caused by a loss of cells in the part of your brain that produces the neurotransmitter dopamine.
Parkinsons disease and the different types of parkinsonism progress in different ways. Some may progress more rapidly than Parkinsons disease. Others, like secondary parkinsonism, may be reversible.
The conditions also respond differently to treatments. For instance, someone who has a type of parkinsonism may not respond to the drug levodopa, which is commonly used for Parkinsons disease.
It can be hard to tell the difference between types of parkinsonism. Heres a look at some of the identified categories of parkinsonism with their typical symptoms and treatments.
- involuntary muscle contractions
Treatment
No treatment has been found to slow the progression of corticobasal syndrome. Parkinsons drugs are generally ineffective but may help manage stiffness in some people.
Whats The Difference Between Drug
Parkinsons is a progressive disorder, which will become worse over time, while DIP does not. In DIP, Parkinson-like symptoms can begin within four days to one month of starting the medication. However, all the symptoms could completely subside once the effecting medication is stopped, though it may take up to 18 months for all the symptoms to subside.

Problems With Balance Or Walking
Bradykinesia can also contribute to increasing instability, walking difficulties and changes in gait. An early symptom of this is a decrease in the natural swing of one or both arms when walking. As things progress, the steps you take may become slower and smaller, and you may start shuffling your feet.
Some people with Parkinsons disease may also experience freezing episodes where it can feel like their feet are stuck in place, which can increase the risk of falling.
What Causes Parkinson’s Disease
Parkinson’s disease occurs when nerve cells, or neurons, in an area of the brain that controls movement become impaired and/or die. Normally, these 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.

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.

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.
Key Brain Changes Are Different
The key brain changes linked to Parkinsons disease and Parkinsons-related dementia are abnormal deposits of common brain proteins, called alpha-synuclein. These deposits are known as Lewy bodies, named after the doctor who discovered them. As more of these proteins clump in the brain, normal brain cells begin to die off.1
In Alzheimers disease, the key brain changes include the buildup of different brain proteins, called amyloid and tau. When amyloid proteins clump together, they form abnormal structures known as plaques. Abnormal groups of tau proteins form tangles.3 Over time, the buildup of these proteins causes normal brain cells to die, and affected parts of the brain may shrink.5

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.
Support For People With Parkinsons 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 Can We Support The Sleep/wake Cycle Of Pdd
For people with PDD who are confused about the day-night cycle, some daily strategies can be helpful. At night, starting a lights out routine that happens at the same hour every day, where all curtains are closed and lights are turned off, can help the person understand that it is sleep time. During the day, opening the curtains, allowing the person with PDD to spend as much time in the daylight as possible, avoiding naps, and organizing stimulating activities, can be helpful. Having lots of calendars and clocks in every room might also help a person with PDD be less confused about the time of day.
Which Age Group Is Parkinsonism More Prevalent In
There is more data on the incidence of Parkinsons disease than there is for Parkinsonism. The incidence of Parkinsons disease increases with age, and the diagnosis is more likely in older populations.
About 4% of people with Parkinsons disease will be diagnosed before they turn 50 years old.

Parkinsons Disease Signs And Symptoms
It can be quite difficult to tell if a person is suffering from Parkinsons disease or not because there can be the involvement of multiple symptoms in a single individual. However, if a person suffers from more than one symptoms of Parkinsons disease, he must go for a doctors appointment.
Following are the fifteen symptoms of Parkinsons disease:
Tremors
Shaking of hands or tremors is one of the most common movement related symptoms of Parkinsons disease. When a person feels slight shaking of his hands at rest, then it is an early sign of Parkinsons disease. A person with Parkinsons disease can notice tremors in his hand, fingers, thumb, or even chin. Low dopamine levels can contribute to uncontrollable shaking of body parts. However, slight shaking is normal if a person exercises a lot or is going through stress but repetitive tremors are a sign of Parkinsons disease.
How Do Doctors Diagnose Parkinsonism
No single test exists for doctors to diagnose Parkinsonism.
A doctor will start by taking a persons health history and review their current symptoms. They will ask for a medication list to determine if any medicines could be causing the symptoms.
A doctor will likely also order blood testing to check for underlying potential causes, such as thyroid or liver problems. A doctor will also order imaging scans to examine the brain and body for other causes, such as a brain tumor.
Doctors can perform a test that tracks the movement of dopamine in the brain. This is known as the DaT-SPECT test.
The test uses radioactive markers designed to track dopamine in the brain. This allows a doctor to watch the release of dopamine in a persons brain and identify the areas of the brain that do or do not receive it.
Because Parkinsonism does not respond to typical treatments and can have a variety of symptoms, doctors can have difficulty coming to a quick diagnosis. It may take time for doctors to rule out other conditions and begin to make treatment recommendations.

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.
What Are Signs And Symptoms Of Parkinsons Disease
Early diagnosis can greatly increase the effectiveness of Parkinsons treatment. However, Parkinsons symptoms are easy to dismiss as normal signs of aging or other conditions such as stroke or head trauma. For these reasons, people may ignore symptoms or doctors may have a harder time with diagnosis.

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.
Whats The Difference Between Corticobasal Degeneration And Parkinsons
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.

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.

What Medications Are Available To Help With Erections
Levodopa does not affect libido. However, its positive effect on mobility leads to increased sexual appetite and activity. The optimization of your antiparkinsonian treatment is therefore often the first solution.
On the other hand, try to plan your intimate moments to the times in the day when your medication is most effective.
Drugs such as sildenafil , vardenafil and tadalafil do not affect sexual drive. They work by increasing the flow of blood to the penis, thereby achieving and maintaining an erection. To be effective, these drugs require sexual arousal.
These supplements should usually be taken about 30 minutes before intercourse, with or without a meal. Fatty foods delay their absorption and therefore their action.
These drugs tend to reduce blood pressure, even more so when combined with the low blood pressure that people with Parkinsons disease usually have and levodopas effect. This low pressure can not only cause dizziness and falls, but can also interfere with your sexual relationship.
Other more invasive drugs exist and may be prescribed to you by a urologist if this class of drugs is not suitable for you.
Stooping Or Hunching Over
Are you not standing up as straight as you used to? If you or your family or friends notice that you seem to be stooping, leaning or slouching when you stand, it could be a sign of Parkinson’s disease .
What is normal?If you have pain from an injury or if you are sick, it might cause you to stand crookedly. Also, a problem with your bones can make you hunch over.

Causes Of Parkinson’s Disease
Parkinson’s disease is caused by a loss of nerve cells in the part of the brain called the substantia nigra.
Nerve cells in this part of the brain are responsible for producing a chemical called dopamine. Dopamine acts as a messenger between the parts of the brain and nervous system that help control and co-ordinate body movements.
If these nerve cells die or become damaged, the amount of dopamine in the brain is reduced. This means the part of the brain controlling movement can’t work as well as normal, causing movements to become slow and abnormal.
The loss of nerve cells is a slow process. The symptoms of Parkinson’s disease usually only start to develop when around 80% of the nerve cells in the substantia nigra have been lost.
Parkinsons Disease Dementia Follow
A person with Parkinsons disease and dementia requires regular checkups with his or her health care professional.
- These checkups allow the health care professional to see how well treatment is working and make adjustments as necessary.
- They allow detection of new problems of cognition, mood, or behavior that could benefit from treatment.
- These visits also give the family caregiver an opportunity to discuss problems in the individuals care.
Eventually, the person with Parkinsons disease and dementia will likely become unable to care for himself or herself or even to make decisions about his or her care if the patient lives long enough with Parkinsons disease and dementia.
- It is best for the person to discuss future care arrangements with family members as early as possible, so that his or her wishes can be clarified and documented for the future.
- A health care professional can advise patients and caregivers about legal arrangements that should be made to ensure that these wishes are observed.
Parkinsons disease dementia prevention
There is no known way of preventing dementia in Parkinsons disease. However, patients with Parkinsons disease are urged to continue to exercise and live a healthy lifestyle as this may delay or reduce the onset of dementia, although there is no good data to indicate this will occur.
