This research depicts the causes, symptoms, diagnosis, and treatment of Parkinson’s disease in older patients. Parkinson 's disease is a chronic disorder that causes a progressive loss of nerve cell function in the part of the brain that controls muscle movement—is an incurable neurological condition with debilitating symptoms. Treatment for younger patients include dopamine agonist drugs that mimic dopamine to stimulate dopamine system in the brain. For older patients, treatment is focused is on providing adequate symptomatic benefit in the near term with as few adverse effects as possible. Also, surgery is highly considered for patients who have motor fluctuations dyskinesia that cannot be adequately managed with medications.
How The Society Perceives Parkinson’s Disease Patients
A Review of the Literature
Imagine walking on a sidewalk, witnessing a group of people mimicking a homeless man with shaky hands and face, what would be the right thing to do? Individuals with disabilities get discriminated and labeled as stupid; they become a laughing stock to ignorant people. To make matters worse, many stand-up comedians and television directors find disability (particularly Parkinson’s disease) a very effective way to make the crowd laugh. This research will familiarize readers with this disease by defining the following questions:
1. What causes Parkinson’s disease?
2. What are the symptoms?
3. How is it diagnosed?
4. What are the available treatments?
What Causes Parkinson’s Disease?
Parkinson Disease’s (PD) is defined as progressive loss of pigmented neurons or cells in the substantia nigra of the brain. These cells manufacture the molecule dopamine, a chemical responsible for regulating purposeful movemen...

...term with as few adverse effects as possible. Also, surgery is considered for patients who have motor fluctuations dyskinesia that cannot be adequately managed with medications. Moreover, the principal surgical action is deep brain stimulation lead implantation; which has made a resurgence in the treatments of PD because long-term complications of Levodopa therapy result in significant disability over time. Another treatment option is injecting stem cells into areas of the brain that require dopamine.
In conclusion, the society must protect and stand up for disabled citizens. It is apparent that there are still numerous ignorant people who deem physically challenged individuals as stupid--they become a laughing stock. It is difficult enough for the disabled to cope with their condition, they need support to ease up their pain. Remember, it can happen to anybody!
Many people, like myself, after watching an episode of “The Michael Jay Fox Show,” started to be come curious as to what exactly this disease is. You ask yourself; What is this disease? What causes it? Can it be passed down from generation to generation? Is there a treatment? What would your life be like suffering from this? Through my research on Parkinson’s disease, I am determined to answer these questions. I hope to have a better understanding on this disease, and how it affects the lives of patients that I might see in a hospital.
People who have been diagnosed with this lifelong disease have either started to see the early signs and symptoms or have yet to recognize them. The negative impact that fatigue, loss of muscle strength and in-coordination has on the patients with Parkinson’s disease can be improved with a well-balanced exercise regimen. The three most common physical symptoms the patient will experience are tremors, rigidity, and bradykinesia. “Tremors while at rest are the most common initial symptom and are present in around 70 percent of cases at disease onset. It often presents as a pill rolli...

Parkinson’s disease is a disorder of the nervous system, and occurs when the brain cells that are in charge of producing dopamine in the body start to slow down the dopamine making process and/or stop it all together. These dopamine producing cells can be found in a grouping of cells called the substantia nigra, which is found in the mesencephalon, also known as the midbrain. What dopamine does is it sends the electrical signals in the brain between the dopamine producing nerve cells from the substantia nigra to the corpus striatum (part of the forebrain). With the right flow of electrical signals between nerve cells, your body will produce smooth muscle movements. When the production of the dopamine is interrupted, slows down, or comes to a stop, this will cause a lack of dopamine. With this lack of dopamine, the muscles in the body will produce shaky and jerky movements instead of the smooth and graceful movements which those muscles are used to. Disrupted for long enough, and during an acute attack of Parkinson’s disease, the dopamine producing cells and the tissue around them will then start to die off causing a short...
Parkinson's is an idiopathic, multifactorial neurodegenerative disease that attacks neurotransmitters in the brain called dopamine. Dopamine is concentrated in a specific area of the brain called the substantia nigra. The neurotransmitter dopamine is a chemical that regulates muscle movement and emotion. Dopamine is responsible for relaying messages between the substantia nigra and other parts of the brain to control body movement. The death of these neurotransmitters affects the central nervous system. The most common symptoms are movement related, including shaking, rigidity, slowness of movement and difficulty with posture. Behavioral problems may arise as the disease progresses. Due to the loss of dopamine, Parkinson's patients will often experience depression and some compulsive behavior. In advanced stages of the disease dementia will sometimes occur. The implications of the disease on the anatomy and physiology of the respiratory and phonatory systems significantly control speech.
Parkinson's disease is a neurological disorder that is named after "the English physician who first described it fully in 1817" (4). The disease causes disturbances in the motor functions resulting in patients having trouble moving. Other characteristics that are not always present in every patient are tremors and stiffening of limbs. All of these characteristics, of the disease are caused by "degeneration of a group of nerve cells deep within the center of the brain in an area called the substantia nigra" (5). Dopamine is the neurotransmitter for these cells to signal other nerve cells. However as the cluster of nerve cells fail to operate, the dopamine can not reach the areas of the brain that affects one's motor functions (5). On average Parkinson's patients have "less than half as much dopamine in their systems as healthy people do" (8). The problem and controversy that arises from this disease is in the cure. Researchers, for years, have been attempting to unravel the mystery of what causes Parkinson's disease and how it can be treated and or cur...
Parkinson’s disease is a chronic, progressive neurodegenerative disorder characterised by resting tremor, slowed movements, rigidity and postural instability (Casey G, 2013). It is the second most common neurodegenerative disorder after Alzheimer’s (Martin and Mills, 2012). There is a great variability in reported incidence rates, probably due to difference in diagnostic criteria and case ascertainment, with reported rates in Australia and in Western countries ranging from 8.6 to 19.0 per 100,000 population (J Macphee and D Stewart, 2012). The two main brain structures affected by Parkinson’s are the substantia nigra pars compacta, which is located in the midbrain and other parts of the basal ganglia, w...
The path physiology of Parkinson’s disease is the pathogenesis if Parkinson disease is unknown. Epidemiologic data suggest genetic, viral, and environmental toxins as possible causes. Nigral and basal loss of neurons with depletion of dopamine, an inhibitory neurotransmitter, is the principal biochemical alteration in Parkinson disease. Symptoms in basal ganglia disorders result from an imbalance of dopaminergic (inhibitory) and cholinergic (excitatory) activity in the caudate and putamen of the basal ganglia.
Nerve cells in the substantia nigra send out fibers to other parts of the brain and release dopamine. Dopamine serves as a chemical messenger allowing communication between the substantia nigra and another area of the brain called the corpus striatum. When functioning, this system coordinates fine and gross motor skills. The gradual degeneration of the substantia nigra causes a lack of the neurotransmitter dopamine, which results in an inability to control body movements. Parkinson disease can also affect emotions and cognition as dopamine also helps regulate emotional responses.
716). Characteristic features of Parkinson's disease include “motor impairment (bradykinesia, rigidity, tremor, gait dysfunction, and postural instability), cognitive impairment (frontal lobe executive dysfunction), and mood disorders” (p. 716). Normally, motor performance depends on the interaction between automatic (unconscious) and volitional (cognitive) control of movement, however those with Parkinson's disease, experience an “early and preferential loss of dopamine in the caudal regions of the basal ganglia (dorsal regions in rodents), which leads to diminished automatic and increased cognitive control of movements that include frontal lobe circuitry” (p. 716). Consequently, those with Parkinson’s disease must sustain a larger cognitive load to execute either motor or cognitive tasks, such as working memory. In the past decade, increasing evidence has accrued for the role of exercise in the improvement of motor performance, which may help both the cognitive and automatic control of movement. Thus, exercise interventions can help those with Parkinson’s disease incorporate goal-based motor skill training, which then helps in engaging circuitry important in motor learning. Individuals with Parkinson's disease become cognitively engaged with the practice and acquiring of movements and skills that were formerly automatic and unconscious. In addition, aerobic exercise is also observed as important for improvement of blood flow and assistance of neuroplasticity in the elderly, which may also play a role in the improvement of behavioral function in those with Parkinson's disease. Petzinger et al. additionally states that exercise also uses goal-based training and aerobic activity which can improve “both cognitive and automatic

Most signs and symptoms of Parkinson disease correspond to one of three motor deficiencies: bradykinesia, akinesia, tremor, and rigidity. The first two qualities are usually present before tremor, but often attributed to aging by the patient and even the physician, and thus the disease is rarely diagnosed until tremor becomes evident much later. An average of 80% of the nigrostriatal neurons may have already degenerated by the time Parkinsonism is diagnosed, which complicates treatment (Fitzgerald, 130). Bra...
Parkinson's Disease is a perpetual, dynamic, neurodegenerative sickness of the elderly for the most part influencing individuals at the age of 60. Nearly 5 million people are suffering from this disease all over the world and 1.2 million people are suffering in United States and Canada with approximately 480 per million people are newly diagnosed each year. This disease not only affects the patient but also it is a cause of worry among patient's loved ones and family members. Though, the news of the recent disease diagnosis haunt every individual and his nears and dears but due to several support groups and societies and several scientific breakthroughs have put a ray of hope in the life of individual living with Parkinson's disease.
Parkinson’s disease is one of the most common nervous system disorders. This disease is part of a group of conditions that are referred to as motor system disorders. Motor system disorders are the result of the loss of dopamine producing brain cells. Dopamine is a neurotransmitter. It acts as the chemical messenger in the transmission of signals in the brain and other vial areas. Dopamine is found in humans as well as animals, including both vertebrates and invertebrates. Further information on dopamine can be found by visiting http://www.news-medical.net/health/What-is-Dopamine.aspx. There are four primary symptoms of Parkinson’s disease, which include (1) tremors or trembling in hands, arms, legs, jaw and face, (2) rigidity or stiffness of the limns and trunk, (3) bradykinesia or slowness of movement, and (4) postural instability or impaired balance and coordination..
Parkinson’s disease is “Characterized by the degeneration of the substantia nigra within the basal ganglia, causing a gradual decrease of the neurotransmitter dopamine” (Webb & Adler, 2008, p. 296). This disease is yet to have a known cause, although researchers are working hard in search of one. In other words, Parkinson’s disease is described as a dopamine deficiency in the caudate nucleus and the putamen (Webb & Adler, 2008, p. 176), and an excess amount of acetylcholine, a neurotransmitter. There is no answer as to why there is a breakdown of these nerve cells that cause Parkinson’s disease. Researchers are pointing to genetic and environmental factors that may be the cause (The Michael J Fox, n.d.).
