Write An Essay On Parkinson's
Before discussing treatments, it is important to understand the general characteristics and causes of Parkinson's. Recall that it is a progressive disorder of the central nervous system that affects the motor system and usually initiated by the slight noticeable tremor of a hand. Early stages may consist of face showing little to no expression and arms not swinging at all for motor balance during walking; decreasing ability to perform unconscious movements such as blinking and smiling. Take Greg for example, he made it clear that when someone smiles at him, he thinks he smiles back when he really doesn't. "It's something I just can't do at the movement and I have to try really hard to perform that simple action that everyone can do just fine," he says. Tremors are a big issue in Parkinson's that may start in a limb (hand or fingers) to back-and-forth rubbing of the …show more content…
One can interpret neuronal loss by analyzing the reduction of neuromelanin, which is the pigment that allow us to visualize the condition of the substantia nigra. A key pathological feature of Parkinson's is based off the microscopic anatomy of the substantia nigra showing Lewy bodies, which are irregular collections of protein that form inside neurons, appearing as spherical masses that take up the space of cellular components (Iacono, et al., 2015). You can think of it as a blood clot that doesn't allow the passage of blood through a vessel. Besides that, neuronal loss is accompanied by the death of astrocytes, which play a key role in nourishing endothelial cells that form the blood brain barrier and activation of microglia, which are the macrophages part of the central nervous system's immune defense. The downside of microglial activation is chronic inflammation that is the fundamental process in contributing to the death of dopamine producing neurons, a characteristic destructive process (Qian, Flood,

    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…

    People with Parkinson's disease can have rigid limbs that affect normal moving, so it is important to not force movement in the affected limb as it can cause pain and damage to the joint. As individuals with Parkinson's also have slower reactions, they will need more time to move and shouldn't be rushed. Carers should also be aware of non-verbal signs of pain and discomfort as the person may not be able to communicate their pain verbally.…

    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:…
