Difference Between Parkinson And Parkinsonism

What Are The Symptoms Of Parkinson Disease

Ask the MD: Is parkinsonism the same as Parkinson’s disease?

Parkinson disease symptoms usually start out mild, and then progressively get much worse. The first signs are often so subtle that many people don’t seek medical attention at first. These are common symptoms of Parkinson disease:

  • Tremors that affect the face and jaw, legs, arms, and hands
  • Slow, stiff walking

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.

Enhancing Healthcare Team Outcomes

A detailed cognitive assessment is essential for the detection of late-onset dementia. Regular exercise helps in maintaining physical health. Appropriate interprofessional physiotherapy and rehabilitation measures are necessary. A comprehensive approach from each specialty, including physicians and specialists, palliative care, social worker, physiotherapist, speech therapist, mental health nurse, and pharmacists, are of utmost importance to enhance patient care. These various disciplines need to collaborate across interprofessional lines to optimize care and outcomes for patients with parkinsonism.

How Do Treatments Differ

MS treatments can ease your symptoms during an attack or slow down the diseaseâs effects on your body.

Steroids like prednisone calm the inflammation that damages your nerves.

Plasma exchange is another therapy if steroids donât work. Your doctor will use a machine to remove the plasma portion of your blood. The plasma gets mixed with a protein solution and put back into your body.

Some people with both diseases who take anti-inflammatory medicines like steroids see their Parkinsonâs symptoms get better.

Disease-modifying treatments slow down MS nerve damage and disability. They include:

Medications to treat Parkinsonâs either raise your dopamine levels or offer a substitute. They can ease Parkinsonâs symptoms like tremors. Over time, they may become less effective.

Medicines used to treat Parkinsonâs include:

Deep-brain stimulation is another treatment for Parkinsonâs. A doctor places electrodes into your brain. They send out electric pulses that ease symptoms in your body.

Lewy Body Dementia: A Common Yet Underdiagnosed Dementia


While its not a household word yet, Lewy body dementia is not a rare disease. It affects an estimated 1.4 million individuals and their families in the United States. Because LBD symptoms can closely resemble other more commonly known disorders like Alzheimers disease and Parkinsons, it is often underdiagnosed or misdiagnosed. In fact, many doctors or other medical professionals still are not familiar with LBD.

Braak Pd Staging Scheme

Although the staging scheme of Braak and co-workers should be considered tentative, it nevertheless, has prompted considerable debate in the field and reawakened recognition of early nonmotor clinical features of PD . Subsequent iterations of the Braak scheme proposed that autonomic neurons in peripheral nervous system may be affected before involvement of the central nervous system and this has prompted recognition that PD is a multiorgan disease process, not merely a disorder of central nervous system . Moreover, it has fed the debate on cell-to-cell transmission of unknown putative disease factors , especially given the fact that fetal mesencephalic intrastriatal transplants to treat PD have been shown to develop Lewy body pathology , possibly by cell-to-cell transmission .

Types Of Parkinsons Disease

Parkinsons disease is caused by the dysfunction and death of dopamine-producing neurons in the brain. Parkinsonism is a broader term that encompasses Parkinsons disease itself, as well as other conditions that cause motor symptoms similar to those seen in Parkinsons, like tremor and abnormally slow movement.

Glial Cytoplasmic Inclusions In Msa

Lantos and co-workers first described glial cytoplasmic inclusions in MSA . Glial cytoplasmic inclusions can be detected with silver stains, in particular, the Gallyas silver stain, but are best seen with antibodies to -synuclein and ubiquitin, in which they appear as flame- or sickle-shaped inclusions in oligodendrocytes. At the ultrastructural level, glial cytoplasmic inclusions are nonmembrane-bound cytoplasmic inclusions composed of 10 to 20nm diameter coated filament similar to the filaments in Lewy bodies .

Although most -synuclein inclusions in MSA are in oligodendroglial cells, certain neuronal populations are vulnerable to neuronal cytoplasmic and intranuclear inclusions, particularly those in the pontine base , inferior olive , and putamen. A few of the neuronal inclusions in MSA resemble Lewy bodies, but their anatomical distribution is distinct from neuronal populations vulnerable to Lewy bodies. Intranuclear -synuclein-immunoreactive inclusions are not found in PD.

Postsynaptic Dopamine D2 Receptor

How to distinguish Parkinson’s disease from Essential Tremor – New Day Northwest

In drug-naïve PD patients compared to controls, binding potential for the G-protein-coupled dopamine D2 receptors measured using 11C-raclopride PET may appear normal or upregulated contralateral to the clinically affected side . Similarly, striatal dopamine D2 receptor upregulation was observed in drug-naïve PD patients using SPECT ligands probably suggesting compensatory changes secondary to nigrostriatal denervation, with higher upregulation detected in the posterior putamen . In medicated PD cases, postsynaptic D2 receptor binding was reduced or within the normal range compared to controls in PET and SPECT studies . Normal D2 binding potential was also observed in patients with DLB and essential tremor , while reductions were reported in atypical PS cases .

In PSP vs. controls, reduced D2 receptor binding was detected in PET and SPECT studies . Likewise, D2 binding reductions were noted in MSA patients compared to PD and controls correlating with striatal glucose hypometabolism . In CBS, studies typically show preservation of postsynaptic D2 receptors, although inconsistently, which is not surprising given the pathologic heterogeneity evident in this disorder .

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.

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.

Symptoms Related To Brain Function Are Different

There is some overlap, but in general, the overall cognitive symptoms that people experience with Parkinsons disease dementia and Alzheimers are different. Alzheimers mainly affects language and memory at the outset, whereas Parkinsons affects problem-solving, speed of thinking, memory, and mood.6

Unlike in Alzheimers disease, people with Parkinsons-related dementia often experience hallucinations, delusions, and paranoid thoughts. Both conditions can lead to depression, anxiety, and sleep disturbances.4,6

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.

Recognizing Other Causes Of Parkinsonism

Although the symptoms and signs of Parkinsons disease are fairly specific, a significant fraction of patients with parkinsonism do not have PD.

In an epidemiologic study of patients with parkinsonism, Schrag et al found that

  • 6% had atypical but non-specific features
  • 2.5 % had progressive supranuclear palsy
  • 2% had dementia with parkinsonism
  • 1.7 % had multiple system atrophy

Identifyingpatients withatypical parkinsonism is important sincethese patients

  • respond less reliably to dopaminergic agents,
  • do not respond favorably to surgical treatments of PD, and
  • develop additional clinical problems.

Atypical parkinsonism should be considered particularly

  • in patients with poor dopamine responsiveness
  • early loss of balance

Medication-induced Parkinsonism

Although tremor and postural instability may be less prominent, this condition may be indistinguishable from PD. Medications frequently associated with the development of parkinsonism include:

The parkinsonism usually resolves after some months after discontinuing the offending medication.

Progressive Supranuclear Palsy

Characteristic of PSP is the early onset of

  • eye movement problems

There is no specific treatment for PSP. Dopaminergic treatment should be tried but often offers little benefit. Supportive measures such as speech therapy, physical therapy and antidepressants may help.

Macroscopic Pathologypd Msa Psp

PD is often unremarkable, with mild frontal atrophy in some cases. There is no significant atrophy of brainstem, and this can be useful in the differential diagnosis of PSP and MSA, in which there is midbrain atrophy in PSP and pontine atrophy in MSA. Sections of the brainstem usually reveal loss of the normally dark black pigment in the substantia nigra and locus ceruleus, but pigment loss in the substantia nigra is also characteristic of PSP and MSA. The loss of pigmentation correlates with neuronal loss of dopaminergic neurons in the substantia nigra and noradrenergic neurons in the locus ceruleus. Pigment loss in the locus ceruleus is consistent in PD, but less predictable in PSP and MSA.

MSA-P has atrophy and brownish discoloration of the posterolateral putamen , the brown color correlating with increased iron pigment. In cases with significant cerebellar signs, there is also atrophy of the pontine base and atrophy and gray discoloration of the cerebellar white matter. More subtle atrophy is noted in the medulla and the cerebellar cortex.

Dementia With Lewy Bodies

Differences Between Essential Tremor and Parkinson’s Disease

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.

Other Types Of Parkinsonism

Like Parkinsons, MSA can cause stiffness and slowness of movement in the early stages. However, people with MSA can also develop symptoms that are unusual in early Parkinsons, such as unsteadiness, falls, bladder problems and dizziness.

PSP affects eye movement, balance, mobility, speech and swallowing. Its sometimes called Steele-Richardson-Olszewski syndrome.

Normal pressure hydrocephalus mainly affects the lower half of the body. The common symptoms are walking difficulties, urinary incontinence and memory problems. Removing some cerebrospinal fluid through a needle in the lower back can help with these symptoms in the short term. If there is improvement after this procedure, an operation to divert the spinal fluid permanently can help in the long term.

While these are not parkinsonian disorders, you may be diagnosed with one of these conditions if tremor is your only symptom.

There are several other, much rarer, possible causes of parkinsonism. These include rare conditions like Wilsons disease, an inherited disorder where theres too much copper in your bodys skin and muscles.

What Is Myasthenia Gravis

Myasthenia gravis is an autoimmune disorder characterized by the production of antibodies that block the transmission of impulses across the neuromuscular junction. These antibodies bind to the postsynaptic Ach receptors, preventing the binding of Ach in the synaptic cleft to those receptors. Women are five times more affected by this condition than males. There is also a significant association with other autoimmune disorders such as rheumatoid arthritis, SLE, and autoimmune thyroiditis.

Fast Facts On Parkinsonism:

  • tremor, especially of one hand

A person with Parkinsonism may have some, but not all, of the symptoms listed above. This is because they also have an additional disorder that affects the brains functioning.

For example, people with Parkinsonism often do not have the hand tremor that affects many people with Parkinsons disease.

Other symptoms associated with Parkinsonism include:

  • issues with the autonomic nervous system, such as problems with controlled movements or spasms
  • early problems with balance
  • rapid onset and progression of symptoms

Each underlying cause of Parkinsonism, such as dementia with Lewy bodies, also has its own unique set of symptoms.

Parkinsonism can be caused by Parkinsons disease itself as well as another underlying condition.

Other causes associated with Parkinsonism include:

The conditions above are the four most common causes of Parkinsonism, according to University of Texas Southwestern Medical Center. The number of people with these conditions is about one-fourth of the amount of people who have Parkinsons disease itself.

Another, less common condition called vascular Parkinsonism also exists. This condition causes multiple, small strokes that can affect a persons balance, walking, and memory.

Parkinsonism is also sometimes the result of taking certain medications. Doctors call this condition drug-induced Parkinsonism. Examples of drugs that could cause it include aripiprazole , haloperidol , and metoclopramide .

Characteristic Clinical Features Of Psp

One of the earliest clinical features of PSP is unexplained falls. Eventually, most patients with PSP develop postural instability, vertical gaze paresis, nuchal and axial rigidity, and dysarthria. Despite many differences in clinical presentation, it is not uncommon for an individual to carry a diagnosis of PD for years before a correct diagnosis of PSP is made . Recently, it has been suggested that a subset of cases of pathologically confirmed PSP have parkinsonism with many similarities to PD, including asymmetry, tremor and partial response to levodopa, PSP-P . Many patients with PSP have cognitive problems or dementia, but this does not help to differentiate PSP from PD, because late in the disease process PD patients also frequently develop dementia and even early in the disease, PD patients may have mild cognitive deficits compared to healthy individuals. On the other hand, most MSA patients have better preservation of cognition.

Psychotic And Other Symptoms

In addition to the symptoms we have already mentioned, other symptoms can appear in both diseases. For example, in Alzheimers disease, delirium appears occasionally, while in Parkinsons disease it practically does not. It is important to remember that delirium is an organic disorder that mainly affects awareness and attention.

In relation to psychotic symptoms, visual hallucinations may appear in both diseases, more or less in the same proportion. There may also be delusions, being frequent in Alzheimers and occasional in Parkinsons.

Treatment Of Rls In Pd

Regardless of the above discussion, it is clear that many people with PD have difficulty falling asleep because of annoying sensations in the legs accompanied by a sometimes unbearable sense of restlessness in the legs. For these people, taking dopamine agonists before bed can be helpful. Caution is in order, of course, because in some patients with PD, especially older or more advanced patients, these medications can cause confusion and hallucinations and are thus not well-tolerated. A long-acting levodopa formulation or medications such as gabapentin, gabapentin enacarbil and pregabalin can also be effective. Trying to address sleep issues such as RLS in patients who have sleep complaints can be an important aspect of maximizing therapy for PD.
