Dementia With Lewy Bodies
Of people with dementia, the type of parkinsonism called dementia with Lewy bodies is the second most common cause of dementia, after Alzheimers disease in the elderly. Many are diagnosed at first with Alzheimers disease due to memory or cognitive disorders and then later as dementia with Lewy bodies as the motor symptoms common to Parkinsons progress.
Lewy bodies are abnormal deposits of protein on the nerve cells in the brain. If the production of dopamine, a neurotransmitter, produced by those nerve cells is disrupted due to the buildup of Lewy bodies on those cells, too little dopamine is produced, which can cause the symptoms of Parkinsons.
What Are The Complications Of Parkinson Disease
Parkinson disease causes physical symptoms at first. Problems with cognitive function, including forgetfulness and trouble with concentration, may arise later. As the disease gets worse with time, many people develop dementia. This can cause profound memory loss and makes it hard to maintain relationships.
Parkinson disease dementia can cause problems with:
- Speaking and communicating with others
- Problem solving
- Paying attention
If you have Parkinson disease and dementia, in time, you likely won’t be able to live by yourself. Dementia affects your ability to care of yourself, even if you can still physically do daily tasks.
Experts don’t understand how or why dementia often occurs with Parkinson disease. Its clear, though, that dementia and problems with cognitive function are linked to changes in the brain that cause problems with movement. As with Parkinson disease, dementia occurs when nerve cells degenerate, leading to chemical changes in the brain. Parkinson disease dementia may be treated with medicines also used to treat Alzheimer’s disease, another type of dementia.
Other Causes Of Parkinsonism
“Parkinsonism” is the umbrella term used to describe the symptoms of tremors, muscle rigidity and slowness of movement.
Parkinson’s disease is the most common type of parkinsonism, but there are also some rarer types where a specific cause can be identified.
These include parkinsonism caused by:
- medication where symptoms develop after taking certain medications, such as some types of antipsychotic medication, and usually improve once the medication is stopped
- other progressive brain conditions such as progressive supranuclear palsy, multiple system atrophy and corticobasal degeneration
- cerebrovascular disease where a series of small strokes cause several parts of the brain to die

Parkinsons Disease Vs Als: Us Prevalence
One million Americans live with Parkinsons disease. The average cost of Parkinsons disease including treatment, lost work wages, and social security payments is $25 billion annually in the U.S.
It is not clear how many people are affected by ALS, but the estimates range between 12,000 and 15,000. Doctors tell roughly 5,000 patients annually that they have ALS. Records on ALS have not been well kept across the country, so estimates may fall way below the actual rates. Common age of ALS diagnosis is between 55 and 75, and life expectancy is anywhere between two and five years after the onset of symptoms. Longevity in ALS is strongly linked to a persons age. Younger individuals with ALS tend to live longer than those diagnosed at an older age.

Whats The Difference Between Vascular Parkinsonism And Parkinsons
As the name implies, vascular parkinsonism is caused by cerebrovascular disease which affects the blood supply to the brain. Vascular parkinsonism is caused by one or more small strokes, while Parkinsons is caused by a gradual loss of nerve cells. One major difference from Parkinsons is that its not progressive, while Parkinsons becomes worse with time. Another difference is that there are no tremors in vascular parkinsonism.

How Is Psp Different From Parkinsons Disease
PSP is often misdiagnosed as Parkinsons disease, especially early in the disorder, as they share many symptoms, including stiffness, movement difficulties, clumsiness, bradykinesia , and rigidity of muscles. The onset of both diseases is in late middle age. However, PSP progresses more rapidly than Parkinsons disease.
- People with PSP usually stand exceptionally straight or occasionally tilt their heads backward . This is termed axial rigidity. Those with Parkinsons disease usually bend forward.
- Problems with speech and swallowing are much more common and severe in PSP than in Parkinsons disease and tend to show up earlier in the disease.
- Eye movements are abnormal in PSP but close to normal in Parkinsons disease.
- Tremor is rare in PSP but very common in individuals with Parkinsons disease.
Although individuals with Parkinsons disease markedly benefit from the drug levodopa, people with PSP respond minimally and only briefly to this drug.
People with PSP show accumulation of the protein tau in affected brain cells, whereas people with Parkinsons disease show accumulation of a different protein called alpha-synuclein.

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.
Motor Circuit In Parkinson Disease
The basal ganglia motor circuit modulates the cortical output necessary for normal movement .
Signals from the cerebral cortex are processed through the basal ganglia-thalamocortical motor circuit and return to the same area via a feedback pathway. Output from the motor circuit is directed through the internal segment of the globus pallidus and the substantia nigra pars reticulata . This inhibitory output is directed to the thalamocortical pathway and suppresses movement.
Two pathways exist within the basal ganglia circuit, the direct and indirect pathways, as follows:
-
In the direct pathway, outflow from the striatum directly inhibits the GPi and SNr striatal neurons containing D1 receptors constitute the direct pathway and project to the GPi/SNr
-
The indirect pathway contains inhibitory connections between the striatum and the external segment of the globus pallidus and between the GPe and the subthalamic nucleus striatal neurons with D2 receptors are part of the indirect pathway and project to the GPe
The STN exerts an excitatory influence on the GPi and SNr. The GPi/SNr sends inhibitory output to the ventral lateral nucleus of the thalamus. Dopamine is released from nigrostriatal neurons to activate the direct pathway and inhibit the indirect pathway. In Parkinson disease, decreased striatal dopamine causes increased inhibitory output from the GPi/SNr via both the direct and indirect pathways .

My dear friends personal story related to Parkinsons disease is also here to help you better understand the disease process. Bill was recently diagnosed with Parkinsons.
Parkinsonism and Parkinsons disease are two terms that can be confusing. According to the Parkinsons Foundation, parkinsonism is a term used to describe a group of neurological conditions that present with motor symptoms that are also found in Parkinsons disease. Parkinsons disease is the most common form of parkinsonism.
Because the chief symptoms of Parkinsons are also found in other types of parkinsonism, it can be difficult for a physician to make a definitive diagnosis in the beginning of the disease process. Parkinsonism can have several different causes that can be totally different from Parkinsons disease.

What Causes Parkinson Disease
Parkinson disease arises from decreased dopamine production in the brain. The absence of dopamine makes it hard for the brain to coordinate muscle movements. Low dopamine also contributes to mood and cognitive problems later in the course of the disease. Experts don’t know what triggers the development of Parkinson disease most of the time. Early onset Parkinson disease is often inherited and is the result of certain gene defects.
Difference Between Dementia With Lewy Bodies And Parkinsons
Dementia with Lewy bodies and Parkinsons Disease are two neurological conditions that have many similarities and differences. Both conditions affect the brain and nervous system, though they cause different signs and symptoms. It is important to understand the differences between these two conditions in order to provide the best care for those living with them. This article will provide an overview of the differences between Dementia with Lewy bodies and Parkinsons disease.

Lifestyle And Other Protective Factors
Cigarette smoking and caffeine consumption are the two most consistent protective factors associated with a reduced risk of PD. Other reported associations include higher serum urate, ibuprofen use and exercise, among others. The negative association between cigarette smoking and PD is most intriguing. This inverse relationship is not easily explained, but some have suggested that PD-related cautious personality predisposes some individuals to quitting neuroprotective smoking as the biological mechanism involved in PD. The other hypothesis links nicotine to dopaminergic neuronal protection since it has been shown to stimulate the release of dopamine in the striatum and preserve dopaminergic function in experimental models. It is also possible that there are other unidentified neuroprotective components in cigarette smoke.
The relative risk reduction of PD among caffeine drinkers is between 0.5 and 0.8 and, similar to smoking, a dose-dependent effect has been consistently demonstrated in most studies. Caffeine, an antagonist of adenosine A2a receptor, has been postulated to exert neuroprotective role by blocking this receptor. In addition to caffeine, it is possible that antioxidants present in some beverages may contribute to a protective effect among black tea drinkers, independent of caffeine.

Parkinsons Vs Multiple Sclerosis: How Are These Conditions Different
Parkinsons Disease and Multiple Sclerosis are two medical conditions that are frequently confused with each other since they are both progressive and have similar symptoms, but there are some significant differences between the two.
Here we will discuss the difference and similarities between the two.
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:

What Is The Difference Between Parkinsons Disease And Parkinsonism
Parkinsons disease is a neurodegenerative disorder that leads to movement symptoms and non-movement symptoms. It is sometimes called idiopathic , but the cause is believed to be a combination of genetic and environmental factors.
Parkinsonism is a more general term that encompasses the symptoms of Parkinsons disease. A variety of disorders or syndromes can lead to Parkinsonism, and these syndromes can lead to faster progression of symptoms, increased falling, presence of hallucinations, and can be non-responsive to levodopa .
The majority of people with the symptoms of Parkinsons disease will be diagnosed with idiopathic Parkinsons disease. Between 10% to 15% of these people will be diagnosed with Parkinsonism that is caused by something else.

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 Can You Tell If Its Parkinsons Disease
Doctors will base a diagnosis on a persons symptoms, including the order in which they appear. Some conditions that resemble Parkinsons disease cause unrelated symptoms in the early stage and do not produce Parkinson-like symptoms until they have progressed.
Other conditions manifest Parkinson-like symptoms early but also cause other symptoms that are not typical of Parkinsons disease.
Diagnosing NPH involves medical tests in addition to an assessment of symptoms. Because NPH is due to poor drainage of cerebral spinal fluid, other diagnostic tools are necessary. These may include:
- physical examination
The combination of carbidopa and levodopa sells under the brand name Sinemet.
Other medications may include:
- dopamine agonists, such as pramipexole , which trigger the production of dopamine in the brain
- amantadine to decrease involuntary movements
- various classes of enzyme inhibitors, which slow enzymes that break down dopamine
- anticholinergic drugs, such as trihexyphenidyl , which decrease tremors and muscle rigidity by blocking acetylcholine, a brain chemical involved in movement
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.
