What Is The Prognosis And Life Expectancy For Parkinsons Disease
The severity of Parkinsons disease symptoms and signs vary greatly from person to peson, and it is not possible to predict how quickly the disease will progress. Parkinsons 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 pneumonia, 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 Advanced Parkinsons Disease
The traditional classification and disease progression of Parkinsons disease orient on disease milestones that can be most obviously followed along motor domains. In this sense, the topography and severity of segmental motor symptoms, followed by more bilateral segmental involvement, finally appearance of gait disturbance, postural impairment and bedridden immobile states provide well defined but also in some way broadly scaled categories of disease stages. Although this and similar classifications are valuable to approximate and describe the motor severity over time, the classifications fall short to comprehensively describe and characterize the full, continuous and multidimensional spectrum of disease-related motor and non-motor symptoms. In recent years, diverse non-motor domains, quality of life, psychosocial burden and stigma have received major attention as determinants of PD disease course and outcome parameters of clinical trials . Diversity in neurodegeneration patterns and involvement of several neurotransmitters and their contribution to motor and non-motor symptom parallel the phenotypic variability .
Characterizing PD patients on such broad scales is essential, since the phenotype of individual patients varies substantially. This diversity leads to ultimate differences in patients therapeutic requirements, and will very differentially affect patients subjective well-being, self-perceived disease-related impairments, and health-related quality of life.
What Is Parkinson’s Disease
Parkinsons disease is a degenerative, progressive disorder that affects nerve cells in deep parts of the brain called the basal ganglia and the substantia nigra. Nerve cells in the substantia nigra produce the neurotransmitter dopamine and are responsible for relaying messages that plan and control body movement. For reasons not yet understood, the dopamine-producing nerve cells of the substantia nigra begin to die off in some individuals. When 80 percent of dopamine is lost, PD symptoms such as tremor, slowness of movement, stiffness, and balance problems occur.
Body movement is controlled by a complex chain of decisions involving inter-connected groups of nerve cells called ganglia. Information comes to a central area of the brain called the striatum, which works with the substantia nigra to send impulses back and forth from the spinal cord to the brain. The basal ganglia and cerebellum are responsible for ensuring that movement is carried out in a smooth, fluid manner .
The action of dopamine is opposed by another neurotransmitter called acetylcholine. In PD the nerve cells that produce dopamine are dying. The PD symptoms of tremor and stiffness occur when the nerve cells fire and there isn’t enough dopamine to transmit messages. High levels of glutamate, another neurotransmitter, also appear in PD as the body tries to compensate for the lack of dopamine.

Stage Four: Symptoms Are Severe And Disabling And You Often Need Assistance To Walk Stand And Move
Stage Four Parkinsons disease is often called advanced Parkinsons disease. People in this stage experience severe and debilitating symptoms. Motor symptoms, such as rigidity and bradykinesia, are visible and difficult to overcome. Most people in Stage Four arent able to live alone. They need the assistance of a caregiver or home health aide to perform normal tasks.
Stratification For Therapeutic Outcomes
Based on the increasingly recognized heterogeneity of PDnot only in terms of underlying genetic and/or environmental causes, but also in terms of clinical presentationsthere is an emerging need for better definitions of subtypes of PD that allow to assign treatments and shape therapeutic approaches according to the best response. As there is still no established neuroprotective treatment option that is able to intervene with the chronic neurodegenerative process, most benefit for the patients in terms of quality of life can be currently achieved by providing access to best symptomatic treatment. This is also reflected by the fact that clinical trials focus on more meaningful parameters in terms of primary and secondary outcomes . Complications of symptomatic pharmacological treatment of PD like dyskinesia remain a significant problem and several recent trials failed to efficiently target dyskinesia at phase III level . Therefore, the translation of novel drugs into successful trials requires the definition of clinically important change that goes beyond the application of clinical rating scales and aligns with the patients observation, e.g., of remission and perception of dyskinesia.

How To Manage Symptoms At The End Of Life
At the end of life, good practice is to plan for any potential symptoms that may arise. The most common symptoms anticipated are pain, dyspnoea, nausea and vomiting, agitation, anxiety, delirium and noisy respiratory secretions.18 For patients with PD particular considerations should be given to the more commonly used medicines, specifically anticholinergics and antidopaminergics. These are usually prescribed for treatment of respiratory secretions and nausea and vomiting. Alternatives are available for respiratory secretions, and include glycopyrronium, in preference to hyoscine hydrobromide. Although this is an anticholinergic, only a small proportion crosses the blood brain barrier.
For nausea and vomiting, ondansetron,19 cyclizine, domperidone have all been suggested in PD.20 However, ondansetron has been shown to be inferior to domperidone in the pre-treatment of apomorphine.21 Cyclizine has anticholinergic properties and may exacerbate confusion, especially when comorbid psychosis or cognitive impairment are present. Levomepromazine, although it has antidopaminergic effects, has been shown to be effective for nausea with rotigotine in a case report.22
Agitation, dyspnoea and pain can all be managed with the same anticipatory medications as recommended.20 Specifically relating to PD, several case reports have supported the intraoperative use of midazolam, during sedation, for tremor and dyskinesias,23,24 as well as for agitation at the end of life.20
What To Expect In The Late Stages Of Parkinsons Disease
The late stages of PD are medically classified as stage four and stage five by the Hoehn and Yahr scale:
- Stage Four of Parkinsons Disease In stage four, PD has progressed to a severely disabling disease. Patients with stage four PD may be able to walk and stand unassisted, but they are noticeably incapacitated. Many use a walker to help them. At this stage, the patient is unable to live an independent life and needs assistance with some activities of daily living. The necessity for help with daily living defines this stage. If the patient is still able to live alone, it is still defined as Stage Three.
- Stage Five of Parkinsons Disease Stage five is the most advanced and is characterized by an inability to arise from a chair or get out of bed without help. They may have a tendency to fall when standing or turning, and they may freeze or stumble when walking. Around-the-clock assistance is required at this stage to reduce the risk of falling and help the patient with all daily activities. At stage five, the patient may also experience hallucinations or delusions.1,2

What Are The Surgical Treatments For Parkinsons Disease
Most patients with Parkinsons disease can maintain a good quality of life with medications. However, as the disease worsens, medications may no longer be effective in some patients. In these patients, the effectiveness of medications becomes unpredictable reducing symptoms during on periods and no longer controlling symptoms during off periods, which usually occur when the medication is wearing off and just before the next dose is to be taken. Sometimes these variations can be managed with changes in medications. However, sometimes they cant. Based on the type and severity of your symptoms, the failure of adjustments in your medications, the decline in your quality of life and your overall health, your doctor may discuss some of the available surgical options.
What Are The Symptoms Of Parkinsons Disease
Symptoms of Parkinsons disease and the rate of decline vary widely from person to person. The most common symptoms include:
Other symptoms include:
- Speech/vocal changes: Speech may be quick, become slurred or be soft in tone. You may hesitate before speaking. The pitch of your voice may become unchanged .
- Handwriting changes: You handwriting may become smaller and more difficult to read.
- Depression and anxiety.
- Sleeping disturbances including disrupted sleep, acting out your dreams, and restless leg syndrome.
- Pain, lack of interest , fatigue, change in weight, vision changes.
- Low blood pressure.

Elucidating Substrates Of Neuropsychiatric Dysfunction In Pd
Our group is particularly interested in the role of noradrenergic pathology in cognitive dysfunction in PD . Significant pathology and loss of LC-NE neurons occurs in PD . LC-NE dysfunction occurs early in disease progression , and the known functions of LC-NE correlate well with several early symptoms in PD including sleep disorders , depression and cognitive dysfunction .
Cognitive dysfunction in early PD primarily manifests as a dysexecutive syndrome including impairments in planning, working memory, attentional control and cognitive flexibility . These functions are associated with prefrontal cortex, which is not subject to direct PD pathology in early stages. The prefrontal cortex is regulated by several neuromodulatory systems including DA, serotonin, acetylcholine and NE . NE, serotonin and cholinergic nuclei that project to prefrontal regions are all subject to PD pathology however, DA inputs to prefrontal regions arise primarily from medial ventral tegmental regions and remain relatively preserved even in late PD .

Complications In Advanced Pd
While worsening of motor function and drug-induced motor complications represents a major challenge in patients with mid-stage to advanced disease, in the advanced stage of PD the most troublesome and distressful complications are usually nonmotor symptoms, including psychiatric and cognitive disorders, autonomic disturbances, and sleep disorders that significantly increase the need for supportive care. Unfortunately, these symptoms are frequently neglected in clinical practice due to limited consultation time, perception of the patient and caregivers that their symptoms are unrelated to the disease, or insufficient awareness of the clinicians, who generally focus on motor symptoms .
Proper supporting care becomes increasingly important in advanced PD. Rehabilitative and support services for patients and family become key interventions as the disease reaches its more debilitating stages and pharmacologic or surgical treatment becomes less relevant. Management of motor and nonmotor complications in advanced PD requires careful and ongoing assessment of whether symptoms are a side effect of medication or related to the progression of the disease .

Unilateral Involvement Only Usually With Minimal Or No Functional Impairment
The patient has tremor, rigidity, slowness and paucity of movement, or poor condition in the arm and/or legs on one side of the body. Occasionally one side of the face is involved, producing an asymmetry of expression that may look very like the effects of a mild stroke or Bells palsy. This stage of Parkinsons is often missed entirely. For example when the diagnosis is made at a more advanced Stage, the patient may remember having noticed an intermittent tremor of one hand many years before. Old home movies may show that the patient didnt swing one arm as much as the other did while walking. One hand or foot may have been clumsier than the other may have. Often these symptoms are so mild that no formal medical attention is sought. If sought it is not uncommon that the physician is unable to make a diagnosis, either by the most assiduous and astute physical examination or by the most advanced technology. Sometimes the disease must evolve over many years before a diagnosis can be made with certainty.
Usually was inserted into the original definition to modify minimal or no functional impairment: because, very rarely, a patient presents with very severe and disabling unilateral symptoms: extreme and violent tremor or rigidity and akinesia in one limb so severe that the limb is virtually paralyzed. Most doctors worry about a stroke or tumor which they should. When all necessary tests show nothing, one must wait and observe. Eventually Stage II may emerge.

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.

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.

Palliative Care Management Of Non
Patients with PD can develop non-motor manifestations, categorized into autonomic dysfunction, cognitive impairment, neuropsychiatric disorders, and sleep disturbances. At the end-stage of PD, non-motor symptoms become more common and can become the most prominent medical problem, leading to increasing decline in quality of life both for patient as well as increasing caregiver burden . Non-motor symptoms occur in up to 50% of PD patients especially in association with the medication off state and may become worse by anti-PD medications . Almost one third of patients reports their non-motor symptoms to be at least as debilitating as their motor symptoms .
All patients with motor fluctuations face at least one non-motor problem during the off phase . In end-stage of PD, dementia, psychosis, and falls become more complex to manage than the motor complications as a result, managing non-motor aspects is important to increase quality of life and decrease the burden of illness . Chaudhuri and co-workers, using a new 30-item non-motor symptom screening questionnaire , found noticeably high scores among PD patients for impaired taste/smell, impaired swallowing, weight loss, constipation, urinary urgency, forgetfulness, dribbling, sadness, hallucinations, anxiety, sexual dysfunction, falling, reduced concentration, daytime sleepiness, vivid dreams, and sweating .
