How Is Psp Different From Parkinson’s 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 Parkinson’s disease usually bend forward.
- Problems with speech and swallowing are much more common and severe in PSP than in Parkinson’s disease and tend to show up earlier in the disease.
- Eye movements are abnormal in PSP but close to normal in Parkinson’s disease.
- Tremor is rare in PSP but very common in individuals with Parkinsons disease.
Although individuals with Parkinson’s 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.
Medications For People With Parkinsons Disease
Symptoms of Parkinsons disease result from the progressive degeneration of nerve cells in the brain and other organs such as the gut, which produce a neurotransmitter called dopamine. This causes a deficiency in the availability of dopamine, which is necessary for smooth and controlled movements.Medication therapy focuses on maximising the availability of dopamine in the brain. Medication regimes are individually tailored to your specific need. Parkinsons medications fit into one of the following broad categories:
- levodopa dopamine replacement therapy
- dopamine agonists mimic the action of dopamine
- COMT inhibitors used along with levodopa. This medication blocks an enzyme known as COMT to prevent levodopa breaking down in the intestine, allowing more of it to reach the brain
- anticholinergics block the effect of another brain chemical to rebalance its levels with dopamine
- amantadine has anticholinergic properties and improves dopamine transmission
- MAO type B inhibitors prevent the metabolism of dopamine within the brain.
Why Do People With Dementia Develop Seizures
Ultimately, anything that changes the structure of the brain can cause seizures.
This happens for some people after a stroke, a head injury, or with a brain infection like meningitis. A similar problem is happening in the brain in dementia. As cells in the brain die and the brain shrinks this can lead to epilepsy.
In addition, we know that two proteins that build up in the brain of people with Alzheimers disease amyloid and tau affect how the brains nerve cells communicate with each other.
Sometimes these nerve cells can become hyper-excitable, meaning they can behave uncontrollably, causing epileptic seizures.
What Symptoms Can Be Expected In Advanced Pd
- Pain 86%
- Shortness of breath 54%
- Problems in swallowing 40%14
In an analysis of 339 death certificates and medical notes in the UK, pneumonia was found to be a terminal event in 45%.13
Caregiver distress with choking and the risk of choking to death is also mentioned in a separate study in to experiences regarding all stages of PD.4
In a survey of symptoms and their association with quality of life, in those patients with advanced disease, uncontrolled pain, anxiety and hallucinations were significantly associated with poor quality of life.9
Seizures are also noted in a description of the last phase of Parkinsonian syndromes,15 and in retrospective studies of PD patients overall.16,17

What Is The Prognosis And Life Expectancy For Parkinson’s Disease
The severity of Parkinson’s disease symptoms and signs vary greatly from person to peson, and it is not possible to predict how quickly the disease will progress. Parkinson’s disease itself is not a fatal disease, and the average life expectancy is similar to that of people without the disease. Secondary complications, such as , falling-related injuries, and choking can lead to death. Many treatment options can reduce some of the symptoms and prolong the quality of life.
What Is Parkinsons Disease
Parkinsonâs Disease is a progressive neurological condition that affects movement.Â
ItÂ is caused by the loss of cells in the brain that produce dopamine, an important neurotransmitter , which enables us to perform smooth, coordinated movements.
The three main symptoms of Parkinson’s are tremor , slowness of movement, and rigidity .Â
It gets progressively worse over time, and although there are some treatments that can relieve the symptoms, there is no cure.
Living With Parkinsons Disease
Depending on severity, life can look very different for a person . As a loved one, your top priority will be their comfort, peace of mind and safety. Dr. Shprecher offered some advice, regardless of the diseases progression. Besides movement issues Parkinsons Disease can cause a wide variety of symptoms including drooling, constipation, low blood pressure when standing up, voice problems, depression, anxiety, sleep problems, hallucinations and dementia. Therefore, regular visits with a experienced with Parkinsons are important to make sure the diagnosis is on target, and the symptoms are monitored and addressed. Because changes in your other medications can affect your Parkinsons symptoms, you should remind each member of your healthcare team to send a copy of your clinic note after every appointment.
Dr. Shprecher also added that maintaining a healthy diet and getting regular exercise can help improve quality of life.Physical and speech therapistsare welcome additions to any caregiving team.
What Are The Important Points Regarding Duodopa At The End Of Life
Duodopa is a continuous infusion of dopaminergic medication administered as a gel into the gut, pumped via a percutaneously inserted gastrostomy tube . There is a requirement for care of the stoma and PEG tube together with functioning of the pump by the patient or carer.41It reduces the time in motor off periods in advanced PD and quality of life.42There is evidence of effective treatment up until death from within a case series.43
How To Avoid Dip
The incidence rate of DIP has proved difficult to assess, due to the prevalence of misdiagnosis as PD. Older people and women are at higher risk of DIP, and genetic factors may also play a role.2
The only way to develop DIP is by taking a prescription drug that impacts the brains dopamine system. If you dont take those drugs, you cannot develop it.
Unfortunately, in some cases, DIP is misdiagnosed as PD. Researchers discovered that 6.8% of patients diagnosed with PD were later reclassified as having DIP.3 This mistake is particularly harmful since doctors may prescribe drugs to manage PD symptoms instead of stopping the drug thats causing DIP.
Discontinuing the responsible drug most often ends DIP. However, in some cases, the symptoms persist. In others, the parkinsonism continues to worsen along a track consistent with PD. Researchers have postulated that in these cases the drugs unmasked PD, which may have otherwise gone unexpressed.
If you dont take a prescription drug that causes DIP, then you cannot develop it. People experiencing DIP can usually end it by discontinuing the medication that caused it, but for some people, the symptoms persist or worsen.
What Causes The Disease
The precise cause of PD is unknown, although some cases of PD are hereditary and can be traced to specific genetic mutations. Most cases are sporadicthat is, the disease does not typically run in families. It is thought that PD likely results from a combination of genetics and exposure to one or more unknown environmental factors that trigger the disease.
The protein alpha-synuclein. The affected brain cells of people with PD contain Lewy bodiesdeposits of the protein alpha-synuclein. Researchers do not yet know why Lewy bodies form or what role they play in the disease. Some research suggests that the cells protein disposal system may fail in people with PD, causing proteins to build up to harmful levels and trigger cell death. Additional studies have found evidence that clumps of protein that develop inside brain cells of people with PD may contribute to the death of neurons.
Genetics. Several genetic mutations are associated with PD, including the alpha-synuclein gene, and many more genes have been tentatively linked to the disorder. The same genes and proteins that are altered in inherited cases may also be altered in sporadic cases by environmental toxins or other factors.
Environment. Exposure to certain toxins has caused parkinsonian symptoms in rare circumstances . Other still-unidentified environmental factors may also cause PD in genetically susceptible individuals.
Signs Of Parkinsons Disease
In 1817, Dr. James Parkinson published An Essay on the Shaking Palsy describing non-motor, as well as, motor symptoms of the illness that bears his . Parkinsons is not just a movement disorder, explained Dr. Shprecher. Constipation, impaired sense of smell, and dream enactment can occur years before motor symptoms of Parkinsons. The latter, caused by a condition called REM sleep behavior disorder, is a very strong risk factor for both Parkinsons and dementia . This has prompted us to join a of centers studying REM sleep behavior disorder.
The Relationship Between Parkinsons Disease And Sleep
Its unclear whether poor sleep causes parkinsonian symptoms to worsen or whether worsening parkinsonian symptoms cause poor sleep. In many cases its likely a case of bidirectionality, with each one exacerbating the other.
Fragmented sleep and sleep deprivation appear to leave the brain more vulnerable to oxidative stress, which has been tied to the development of Parkinsons disease. Parkinsons disease is not usually diagnosed until individuals have developed sufficient motor symptoms, by which time a significant portion of brain cells have already been damaged. If poor sleep quality or having sleep disorders foreshadows the development of parkinsonian symptoms, these could be useful in early diagnosis of the disease.
More research is needed to clarify the multifaceted relationship between Parkinsons disease and sleep. A better understanding of this connection may offer medical experts the unique opportunity to screen at-risk individuals and perhaps delay the onset of the disease.
Who Is Affected By Parkinsons Disease
Several studies have found that the incidence of PD is much more common in than .2,4 One estimate found that PD affects about 50 percent more men than women.2 The reasons for the differences in men and women with PD are unclear, although some suggested explanations are the protective effect of estrogen in women, the higher rate of minor head trauma and exposure to occupational toxins in men, and genetic susceptibility genes on the sex chromosomes.4
People with a close family member with Parkinsons have a small increased risk of developing the disease. About 15 percent to 25 percent of people with PD have a known relative with the disease.2
It is estimated that about 10 million people worldwide are living with PD. The incidence of the disease is higher in industrialized countries.3,4
The incidence of PD increases with age: while PD affects 1 percent of the population over the age of 60, this increases to 5 percent of the population over the age of 85.1
Approximately 5 percent of people with PD are diagnosed before the age of 60.1
Urban areas have a higher prevalence and incidence of PD.5
How Can People Cope With Parkinson’s Disease
While PD usually progresses slowly, eventually daily routines may be affectedfrom socializing with friends to earning a living and taking care of a home. These changes can be difficult to accept. Support groups can help people cope with the diseases emotional impact. These groups also can provide valuable information, advice, and experience to help people with PD, their families, and their caregivers deal with a wide range of issues, including locating doctors familiar with the disease and coping with physical limitations. A list of national organizations that can help people locate support groups in their communities appears at the end of this information. Individual or family counseling may also help people find ways to cope with PD.
People with PD may also benefit from being proactive and finding out as much as possible about the disease in order to alleviate fear of the unknown and to take a positive role in maintaining their health. Many people with PD continue to work either full- or part-time, although they may need to adjust their schedule and working environment to accommodate their symptoms.
How Is Parkinsons Disease Dementia Diagnosed
No single test can diagnose Parkinsons disease dementia. Instead, doctors rely on a series or combination of tests and indicators.
Your neurologist will likely diagnose you with Parkinsons and then track your progression. They may monitor you for signs of dementia. As you get older, your risk for Parkinsons dementia increases.
Your doctor is more likely to conduct regular testing to monitor your cognitive functions, memory recall, and mental health.
Factors That Are At Risk
The neurosurgeon in Guntur lists out the following are some of the risk factors for Parkinsons disease:
- Your age. Parkinsons disease affects just a tiny percentage of young individuals. It usually starts in middle or late life, and the risk grows as you become older. The condition usually strikes people at the age of 60 or older.
- Youre more likely to develop Parkinsons disease if you have a close family who has it. Unless you have many Parkinsons disease relatives in your family, your risks are relatively low.
- Men are more prone than women to develop Parkinsons disease.
- Toxic exposure is a concern. Continuous exposure to herbicides and pesticides may increase your risk of Parkinsons disease by a small amount.
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.
Parkinsonism Falls And Fracture Risk
All forms of parkinsonism, both PD and DIP, have implications for bone health. A 2014 meta-analysis on PD and fracture risk concludes that PD increases the risk of fracture.4
Given that the symptoms of parkinsonism affect balance, motor skills, gait, and the bodys ability to control movement, it is no surprise that people with PD are more likely to experience a fall than people without PD. Here is an excerpt from a 2016 study comparing the incidence of falls and fracture in PD patients:
It is estimated that 60.5% of patients with PD experience at least one fall and 39% have recurrent falls. The high frequency of falls consequently contributes to the increased risk for fractures in PD patients, which has been estimated to be approximately two times the risk in healthy controls. It has been estimated that 76% of falls in PD patients require health care services and 33% result in fractures. Falls and fractures may result in a series of unfavorable outcomes, such as disabilities and death. Furthermore, among PD patients with fractures, the mortality rate is approximately 10.6%.5
All too often, doctors prescribe these drugs without appropriate consideration of this risk. This excerpt from a study on DIP clarifies the danger of accepting a prescription of an unnecessary or inappropriate prescription drug:
Shockingly, the drugs that cause DIP are still being prescribed. This yet one more example further proving that the FDAs drug approval process is useless.
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.
When To See A Doctor
Seek immediate medical help if any of the following occurs:
- The seizure lasts more than five minutes
- Breathing or consciousness doesnt return after the seizure stops
- A second seizure follows immediately
- You have a high fever
- Youre experiencing heat exhaustion
- Youve injured yourself during the seizure
- If you experience a seizure for the first time, seek medical advice.
Can Seizures Be Managed In People With Dementia
There is good news. There are medications that are effective at reducing, and hopefully stopping, epileptic seizures.
If you think that you, or someone you know with dementia may be having epileptic seizures you should tell a doctor. They might want to perform some extra tests, and may want to start some extra medications to treat this problem.
What we dont know yet is whether starting treatment for epilepsy might help to slow down dementia and whether it might help keep peoples memory function better for longer.
We have learned so much about the brain but there is still so much to discover.
Support dementia research
Alzheimers Society is working tirelessly to challenge perceptions, fund research and improve care and support. We rely on your donations. Lets take on dementia together.
The Use Of Levodopa And Peripheral Neuropathy
There are reports in the literature that levodopa use may increase the risk of peripheral neuropathy, although other studies suggest that this is not the case. There are studies that demonstrate for example, that cumulative Levodopa exposure correlates to prevalence of PN in people with PD. Other studies however, demonstrate no difference in the prevalence of PN whether the person was treated with Levodopa or not, suggesting that Levodopa treatment does not play a role in development of PN.

What Lifestyle Changes Can I Make To Ease Parkinsons Symptoms
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.
New Diagnostic Standards For Parkinsons
Until recently, the gold-standard checklist for diagnosis came from the U.K.s Parkinsons Disease Society Brain Bank. It was a checklist that doctors followed to determine if the symptoms they saw fit the disease. But thats now considered outdated. Recently, new criteria from the International Parkinson and Movement Disorder Society have come into use. This list reflects the most current understanding of the condition. It allows doctors to reach a more accurate diagnosis so patients can begin treatment at earlier stages.
How Is Psp Diagnosed
Currently there are no tests or brain imaging techniques to definitively diagnose PSP.An initial diagnosis is based on the persons medical history and a physical and neurological exam. Identifying early gait problems, problems moving the eyes, speech and swallowing abnormalities, as well as ruling out other similar disorders is important. Diagnostic imaging may show shrinkage at the top of the brain stem and look at brain activity in known areas of degeneration.
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.
The 5 Stages Of Parkinsons Disease
Getting older is underrated by most. Its a joyful experience to sit back, relax and watch the people in your life grow up, have kids of their own and flourish. Age can be a beautiful thing, even as our bodies begin to slow down. We spoke with David Shprecher, DO, movement disorders director at Banner Sun Health Research Instituteabout a well-known illness which afflicts as many as 2% of people older than 65, Parkinsons Disease.
Lewy Body Dementia Vs Parkinsons Disease Dementia
Diagnoses of Lewy body dementia include dementia with Lewy bodies and Parkinsons disease dementia. Symptoms in both of these diagnoses can be similar.
Lewy body dementia is a progressive dementia caused by abnormal deposits of a protein called alpha-synuclein in the brain. Lewy bodies are also seen in Parkinsons disease.
The overlap in symptoms between Lewy body dementia and Parkinsons disease dementia include movement symptoms, rigid muscles, and problems with thinking and reasoning.
This seems to indicate that they could be linked to the same abnormalities, though more research is needed to confirm that.
The later stages of Parkinsons disease have more severe symptoms that may require help moving around, around-the-clock care, or a wheelchair. Quality of life can decline rapidly.
Risks of infection, incontinence, pneumonia, falls, insomnia, and choking increase.
Hospice care, memory care, home health aides, social workers, and support counselors can be a help in later stages.
Parkinsons disease itself isnt fatal, but complications can be.
Research has shown a median survival rate of about
Causes Of Parkinson’s Disease
Parkinson’s disease is caused by a loss of nerve cells in part of the brain called the substantia nigra. Thisleads to a reductionin 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.
Environmental Factors And Exposures
Exposure to and a history of head injury have each been linked with PD, but the risks are modest. Never having smoked cigarettes, and never drinking caffeinated beverages, are also associated with small increases in risk of developing PD.
What Are The Five Stages Of Parkinsons Disease
The five stages of Parkinsons disease are called Hoehn and Yahr. Stage one showcases the symptoms affecting one side of the body. In stage two, the symptoms affect both sides of the body with no deterioration or loss of balance. Stage three reveals balance impairment but the person may be physically independent. Stage four depicts a grave disability of movement but the person may still walk unassisted. In stage five, the condition deteriorates further and the person is bound by the wheelchair or bedridden.
Whats The Connection Between Paraquat And Parkinsons
Paraquat is a toxic herbicide, and people exposed to paraquat can develop multiple health issues, such as pain, vomiting, and diarrhea. Paraquat exposure can lower your blood pressure, and ingesting even small amounts can cause severe health problems, including kidney failure and heart failure.
Ingesting large quantities can trigger a coma, cause muscle weakness, produce respiratory issues, or cause seizures. The U.S. Centers for Disease Control and Prevention reports that ingesting large amounts of paraquat is typically fatal. Studies indicate paraquat exposure can cause Parkinsons. These studies provide legal grounds for lawsuits against paraquat producers when exposure to paraquats linked to Parkinsons disease.
