What Causes Parkinsons Disease
Parkinsons disease occurs when nerve cells in an area of the brain called the substantia nigra become impaired or die. These cells normally produce dopamine, a chemical that helps the cells of the brain communicate . When these nerve cells become impaired or die, they produce less dopamine. Dopamine is especially important for the operation of another area of the brain called the basal ganglia. This area of the brain is responsible for organizing the brains commands for body movement. The loss of dopamine causes the movement symptoms seen in people with Parkinsons disease.
People with Parkinsons disease also lose another neurotransmitter called norepinephrine. This chemical is needed for proper functioning of the sympathetic nervous system. This system controls some of the bodys autonomic functions such as digestion, heart rate, blood pressure and breathing. Loss of norepinephrine causes some of the non-movement-related symptoms of Parkinsons disease.
Scientists arent sure what causes the neurons that produce these neurotransmitter chemicals to die.
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.

Nutrition Hydration And Genitourinary Care
Malnutrition is a common problem in advanced PD patients. It is caused by difficulty feeding, altered satiety mechanism, diminished gastric and intestinal motility, inactivity, lack of appetite, dysphagia, and metabolic syndrome. In patients still able to eat independently, meal and portion sizes should be monitored in order to provide sufficient nutrition. Any effort, including compensatory strategies, should be considered to delay the PEG placement. Adequate hydration is another concern for late-stage PD patients, since even mild temperature change can lead to relative dehydration and exacerbate confusion and OH and cause syncope. Many patients become embarrassed when eating or drinking, and nursing assistance, can assure adequate nutrition and hydration through a nonjudgmental caregiver that assist patients with the administration of meals.
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.

What Are The 5 Stages Of Parkinsons Disease
Parkinsons disease is unique as the side effects and symptoms can impact people in different ways. The main symptoms of Parkinsons include uncontrollable shaking or tremors, slowed movement, balance difficulties and stiffness in limbs.;
The symptoms of Parkinsons disease often vary between individuals, with each patients experience varying in intensity. Not everyone will experience all Parkinsons symptoms, yet these are the typical stages of progression that have been outlined by experts as the disease begins to worsen. The different stages of Parkinsons disease help doctors and other professionals evaluate how far the disease has advanced in their patients to identify an appropriate course of action.;
Stage : Mild Cognitive Impairment
Clear cognitive problems begin to manifest in stage 3. A few signs of stage 3 dementia include:
- Getting lost easily
- Noticeably poor performance at work
- Forgetting the names of family members and close friends
- Difficulty retaining information read in a book or passage
- Losing or misplacing important objects
- Difficulty concentrating
Patients often start to experience mild to moderate anxiety as these symptoms increasingly interfere with day to day life. Patients who may be in this stage of dementia are encouraged to have a clinical interview with a clinician for proper diagnosis.

Stage 4 The Advanced Stage Of Parkinsons Disease
This is considered the advanced stage of the disease during which the symptoms become severe and problematic. Loss of balance is common that can lead to falls and result in serious injuries. The patient can still stand and walk but may need a walker all the time. The patient increasingly depends on others for functioning. Depression-like symptoms may also appear in some patients.
Parkinsons Disease Symptoms Of Dementia
Up to one-third of people living with Parkinson’s disease experience dementia, according to the Parkinson’s Disease Foundation. Problems with dementia may include trouble with memory, attention span, and what is called executive function the process of making decisions, organizing, managing time, and setting priorities.

The Role Of Dementia And Age
Dementia also plays an important role in survival with Parkinson’s. By the end of the above study, nearly 70% of the population with Parkinson’s had been diagnosed with dementia, and those with dementia had a lower survival rate as compared to those without.
This means that those with dementia were more likely to die during the six-year period than those without dementia. In addition, scientific studies have shown that increasing age is linked to an increased risk of death.
It’s important to remember that how a person’s Parkinson’s disease manifests and progresses is variable, and a person’s neurologist cannot accurately predict individual life expectancy.
There are simply no key signs or symptoms that allow a doctor to perfectly predict longevity. An older age and the presence of dementia are simply associated with an increased risk of dying.
Hospice Care For Late Stage Parkinsons
There are a number of reasons why choosing to have home health care services for Parkinson patients is one of the best options. Hospice care for late stage Parkinsons is extremely important.
- End of Life 40% of those who were in a long term care facility died alone without a family member being with them. Every person in the study listed who had in home health care and hospice had at least 1 significant family member or loved one with them at the time of their passing.
- Satisfaction 83% of those who utilized hospice were satisfied to highly satisfied with their experience. They cited their satisfaction with the ability to handle the extreme grief and handling of the symptoms of the disease as two of the main reasons for being appreciative with the care received.
- Focus Hospice care for late stage Parkinsons focuses on comfort care, symptom care, grief counseling and acceptance. Maintaining a level of understanding and comfort for both the patient and their loved ones is a primary goal.
We can see the importance of a loved one remaining at home as they battle PD, especially as they move towards the final stages of the disease. Above & Beyond Home Health Care can be there for you with professional hospice care for late stage Parkinsons so you know that your loved one is provided for with the best care possible.

Bilateral Or Midline Involvement Without Impairment Of Balance
Months or years later similar symptoms and signs are noticed on the opposite side of the body, or other signs appear in midline what physicians call Axial signs. These may include: bilateral loss of facial expression ; decreased blinking; speech abnormalities; soft voice, monotony, fading volume after starting to speak loudly, slurring, stiffness of truncal muscles making the patient appear awkward and stiff or resulting in neck and back pain; postural abnormalities causing stooping, generalized slowness in, but still capable of, carrying out all activities of daily living, sometimes an aggravation to those waiting for the patient to complete tasks.
Usually the diagnosis is easy at this Stage if it has been preceded by a clear cut tremor or other symptom on one side. But not all Parkinson’s patients have tremor or other definite signs of Stage I unilateral Parkinsonism. If Stage I was missed and the predominant symptoms at Stage II are only slowness and a lack of spontaneous movement, the diagnosis may still be in doubt. For example, even in Stage II, Parkinsonism may be interpreted as only advancing age.
Hospice Eligibility For Parkinsons Disease
Due to the progressive nature of Parkinsons disease, it can be challenging for families to know when their loved one is eligible for the support of hospice care. If a loved one has been diagnosed with six months or less to live or if they have experienced a decline in their ability to move, speak, or participate in the activities of daily living without caregiver assistance, it is time to speak with a hospice professional about next steps.;

What Are The Non
Parkinson’s disease stages are defined by the severity of a patient’s motor symptoms and how much those symptoms impact one’s ability to function every day. But there are non-motor symptoms that are more likely to develop later in the disease, too, and a doctor may take those into consideration when assessing someone with the disorder.;
For example, people with late-stage Parkinson’s disease might have difficulty chewing, eating, speaking, or swallowing , which is considered both a motor and non-motor symptom. Dysphagia in particular can lead to serious health problems like malnutrition, dehydration, and aspiration.
In the final stages of Parkinson’s disease, a person might develop cognitive changes, including slowness of memory or thinking, trouble planning and accomplishing tasks, and difficulty concentrating. Or they might notice changes in their bone health or vision.
But there’s no telling for sure if or when these symptoms will occur in any individual because Parkinson’s disease symptoms vary from person to person.
How Is Parkinson’s Managed
There is currently no cure for Parkinsons but there are medications and therapies that can help to manage Parkinsons symptoms.
Medicines that increase the level of dopamine in the brain are the main treatment used to manage the;symptoms of Parkinson’s. Medicines are tailored to each individuals needs.
Symptoms will get worse when someones Parkinsons medicines are wearing off and improve again after Parkinsons medicines are taken. If people with Parkinsons dont get their medication at the right time, it leads to their motor symptoms becoming uncontrolled. It can take some time to get their symptoms under control again.;If you work in a hospital or care home, it is important to be aware that medicine timings will vary from person to person and may be different to ward medicine rounds.
As well as medicines, surgical options are available for some people with;Parkinson’s, depending on their symptoms.
Treatments can help to manage the symptoms, but may become less effective in the later stages of the condition.

As of 2021, there is no definite cure for Parkinsons disease. There is also no definite known cause. Its likely due to a combination of an individuals susceptibility and environmental factors. Most cases of Parkinsons disease happen without a genetic link.
According to research published in 2012, only report having a family member with the disease. Many toxins are suspected and have been studied, but no single substance can be reliably linked to Parkinsons.
However, research is ongoing. Its estimated that
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

Parkinsons Disease: Is Death Inevitable
Death is inevitable for us all, but Parkinson’s disease in itself is not a death sentence. Your prognosis will depend on your age, general health, and how your Parkinson’s has progressed. However, there is no reason to assume that you won’t continue to live a full and productive life with the condition.
Scientists are performing new medical trials and research all the time to look for a cure for Parkinsons disease, while our understanding of medications and treatments is better than it has ever been. Therefore, there are plenty of ways you can control the symptoms of Parkinsons disease and make changes to your lifestyle as necessary. Many Parkinsons patients take up yoga, gardening, swimming and walking to improve their strength, flexibility and mental health. Others use physical therapy, massage and meditation to help keep symptoms at bay. These are great ways to extend your life expectancy with or without Parkinsons disease.

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.

Stage 1 Of Parkinsons Disease
This beginning stage of Parkinsons disease has minimal symptoms, if any at all. If symptoms are present, they may include tremors and affect one side of the body. For example, one side of the face may be affected, or one hand or leg may feel slower than the other. Your family and friends may notice changes in your posture or facial expressions. Any symptoms that are present arent severe enough to interfere with daily activities. Diagnosis is difficult at this stage, and the affected person may not even seek medical attention at this point.
Is Parkinsons Disease Fatal
Parkinsons disease itself doesnt cause death. However, symptoms related to Parkinsons can be fatal. For example, injuries that occur because of a fall or problems associated with dementia can be fatal.
Some people with Parkinsons experience difficulty swallowing. This can lead to aspiration pneumonia. This condition is caused when foods, or other foreign objects, are inhaled into the lungs.

Stage Three Of Parkinsons Disease
Stage three is considered mid-stage and is characterized by loss of balance and slowness of movement.
Balance is compromised by the inability to make the rapid, automatic and involuntary adjustments necessary to prevent falling, and falls are common at this stage. All other symptoms of PD are also present at this stage, and generally diagnosis is not in doubt at stage three.
Often a physician will diagnose impairments in reflexes at this stage by standing behind the patient and gently pulling the shoulders to determine if the patient has trouble maintaining balance and falls backward . An important clarifying factor of stage three is that the patient is still fully independent in their daily living activities, such as dressing, hygiene, and eating.
