Parkinson Disease
Parkinson disease is a disease of the nervous system that affects movement. The disease is characterized by progressive loss of nigrostriatal dopaminergic cells due to a dopamine deficiency. Brain cell connections degenerate and die causing memory loss and destroying other important mental functions. Researchers are still unsure as to why the disease develops. A combination of genetic and environmental factors are thought to contribute to the risk of getting Parkinson's, says Catherine Kopil, PhD.Several genetic mutations have been found that are linked to Parkinson's disease, and lifestyle may also play a role.
Parkinson disease is the second most common neurologic disorders under Alzheimer's and affects approximately 1% of individuals older

    In this study, they had 136 drug-naïve patients who had early Parkinson’s Disease, and 50 who were normal, and the people who had the disease were divided into different subtypes: tremor dominant, which don’t show as aggressive symptoms than the other subtype, non-tremor dominant do. They compared their relationship of non-motor symptoms with their quality of life between the people who didn’t have this disease and the people who did have this…

    Parkinson’s disease, a chronic disease with unknown causes, attacks brain cells, specifically the ones that control body movement. This causes shaking, stiff limbs, and poor coordination. Because of this, Professor Trond Riise and colleagues Anders Engeland and Kjetil Bjørnevik started the painstaking work of analyzing over 100 million prescriptions in Norway. Their research started in 2004 and continues to this day. In their study, the medicines that were most associated with the treatment of Parkinson’s were asthma medicine, the use of which halves the risk of getting the disease. (Inversely, one type of high blood pressure medicine doubles the risk.) These new discoveries, according to the article…

    A neurological condition that causes tremors and stiffness, Parkinson's disease is diagnosed in 60,000 Americans each year. The majority of those diagnosed are over the age of 60. Scientists have identified seven genes that are responsible for causing some form of Parkinson's disease. While the disease is chronic and typically worsens over time, medications, exercise and a healthy diet can minimize symptoms and help your loved one to manage their symptoms.…

    Nerve cells use a brain chemical called dopamine to help control muscle movement. Parkinson 's disease occurs when the nerve cells in the brain that make dopamine are slowly destroyed. Without dopamine, the nerve cells in that part of the brain cannot properly send messages. This leads to the loss of…

    As a significant number of elderly patients with early Parkinson's disease symptoms assume that their traits may form part of normal aging and do not seek medical help, obtaining accurate statistics is probably impossible. There are also several different conditions which sometimes have comparable signs and symptoms to Parkinson's, such as drug-induced Parkinsonism, head trauma, encephalitis, stroke, Lewy body dementia, corticobasal degeneration, multiple system atrophy, and progressive supranuclear pasly`.…

    The Basal Ganglia

    • 167 Words
    • 1 Page

    When someone is diagnosed with Parkinson’s disease it means that there is a dysfunction occurring in that person’s Basal Ganglia. The Basal Ganglia are nuclei that are interconnected with other cortical and subcortical structures. They are located deep to the cerebral cortex and are superior to the brainstem. The issue with Parkinson’s disease is that there is a disturbance between the two pathways of the Basal Ganglia. A lesion to the Substantia Nigra par compacta causes the disruption between the direct and indirect pathway; destruction of this type of neural tissue results in the lack of production of dopamine and the inability to excite the neurons in the direct pathway and inhibit the neurons of the indirect pathway. Due to the over-excitement…

    It is well known that people suffering from chronic diseases have major impact in the healthcare delivery systems, including the elderly population over the age of 65. With the advances in technology combined with the aging population, more people are living longer with chronic diseases. Longer life expectancies count for higher costs in healthcare for the treatment, management and prevention of further complications arising from chronic diseases. The third most common chronic disease of the older adults is Parkinson’s disease. It is a debilitating disease affecting a person’s motor ability, causing tremors, rigidity, akinesia or slow movement, and postural instability. According to the National Institutes of Health, about 500, 000 individuals in the United States suffer from Parkinson’s Disease, and it is estimated that males are more often affected than females. Parkinson’s disease has a large economic impact and directly affects medical costs, as well as the affecting the person financially, such as lost wages and decreased productivity. According to a recent interview with a client suffering from PD over the course of ten years, the disability directly impacted his personal life, financial status, and family members. The next discussion talks about how the patient learned about his disease and the personal impact it created at the beginning of the disease process until the peak onset later in his life.…

    Parkinson Disease

    Parkinson disease is a gradually progressive degenerative disorder of the central nervous system. Parkinson disease belongs to a group of conditions called movement disorders. There are four characteristic problems caused by Parkinson disease, including tremor at rest, balance problems, stiffness, and slowness of movement. Parkinson disease occurs when areas of the brain, including an area called the substantia nigra, is slowly destroyed. The exact reason for this destruction is not completely known. In some patients, it may be due to genetic, environmental, or a combination of both causes. The end result is a deprivation in the brain of an important neurochemical, called dopamine. Dopamine helps regulate movement, and its loss leads to increased tone, rigidity, and slowness of movement. Lack of dopamine results in the symptoms associated with Parkinson disease .Approximately 50,000 Americans are diagnosed with Parkinson disease every year. 95% of those diagnosed are over 50 years old. At any given time, about 500,000 people, or 1% of those over age 50 in the US are struggling with this condition. Diagnosis of Parkinson disease is a clinical one, based on history and physical examination. There are no lab tests to definitively diagnose the condition. Your doctor will ask about your medical history and perform a thorough physical exam. A systematic neurological exam will include testing your reflexes and observing things like muscle strength throughout your body, coordination, balance, and other details of movement, including:…
