Essay about Parkinsons Disease - 588 Words

Parkinsons Disease Damage to Brocas area in the frontal lobe causes difficulty in speaking and writing, a problem known as Brocas aphasia. Injury to Wernickes area in the left temporal lobe results in an inability to comprehend spoken language, called Wernickes aphasia. Cerebral palsy is a broad term for brain damage sustained close to birth that permanently affects motor function. The damage may take place either in the developing fetus, during birth, or just after birth and is the result of the faulty development or breaking down of motor pathways. Cerebral palsy is non-progressive that is, it does not worsen with time. During childhood development, the brain is particularly susceptible to damage because of the rapid growth†¦show more content†¦The chief neurotransmitter#8212;or carrier of nerve signals#8212;in this area of the brain is dopamine, which is deficient in people who have Parkinsons. The cause of this deficiency is not known, but research suggests that several factors may reinfor ce each other to produce Parkinsons disease. There may be a genetic predisposition for some forms of the disease#8212;between 15 and 20 percent of people with Parkinsons are closely related to an individual who displays the diseases characteristic symptoms. In 1996 scientists identified a gene associated with a rare form of Parkinsons disease. Genetic predisposition may be limited only to rare forms of the disease, however. A 1999 study found that the most common form of Parkinsons disease is not inherited, suggesting that exposure to certain environmental agents may be a primary cause. Although the identity of these agents remains unknown, candidates include harmful pesticides or toxins in food; and free radicals, which are unstable molecules that may contribute to neuron damage by reacting with other molecules#8212;especially metallic elements such as iron#8212;in the basic chemical process known as oxidation. Introduction of the drug L-dopa, or levodopa, in the mid-1960s led to the relief of Parkinsons symptoms in many people with the disease. L-dopa stimulates the production of dopamine in surviving neurons in the substantia nigra. L-dopa becomes less effectiveShow MoreRelatedThe Parkinsons Disease1596 Words   |  6 PagesMany people around the world today suffer from Parkinson’s disease and other movement disorders. A movement disorder is a disorder impairing the speed, fluency, quality, and ease of movement. There are many types of movement disorders such as impaired fluency and speed of movement (dyskinesia), excessive movements (hyperkinesia), and s lurred movements (hypokinesia). Some types of movement disorders are ataxia, a lack of coordination, Huntingtons disease, multiple system atrophies, myoclonus, briefRead MoreThe Parkinsons Disease761 Words   |  3 PagesMathur states that â€Å"Genetics loads the gun, environment pulls the trigger† (Mathur). Parkinson’s Disease (PD) exhibits this pattern, with the vast majority of PD cases being idiopathic, likely the result of combined genetic and environmental factors. While many researchers previously sought symptom-specific treatment, recent breakthroughs open the door for the discovery of genetic and environmental causes so that disease prevention, and even reversal, emerge as viable possibilities. Recent research demonstratesRead More Parkinsons Disease Essay1764 Words   |  8 PagesParkinson’s disease (PD) is a striatal dopamine deficiency disorder as a consequence of neuronal loss in the substania nigra. It is named after James Parkinson, a British apothecary, who first fully documented its physical signs in 1817. Since then, significant advances have been made in our understanding of characteristic pathophysiology as well as in the medical treatment of different stages of PD.

It belongs to a group of conditions known as movement disorders. Parkinson disease is a component of hypokinetic disorder because it causes a decreased in bodily movement. It affects people who are usually over the age of 50. It can i mpair an individual motor as well as non-motor function.

The disease begins to occur around age 40 and has incidence with patient age. One survey found that PD may affect 1% of the population over 60. Incidence seems to be more prominent in men, and tends to progress to incapacity and death over one or two decades.

The average onset of this disease usually is for people over the age of 50, with the baby boomers getting older there may be an increase in this disease, as much as 9 million people worldwide.

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 affectsRead MoreEssay Parkinsons Disease3763 Words   |  16 PagesParkinsons Disease In 1817, James Parkinson published his famous treatise: An Essay on the Shaking Palsy, describing the symptoms which now collectively bear his name. Although many scientists before his time had described various aspects of motor dysfunction (ataxia, paralysis, tremor) Parkinson was the first to collect them into a common syndrome; one which he believed formed a distinctive condition.

It is common for patients with PD to have motor symptoms such as gait disorder, which comes from muscle stiffness/rigidity, bradykinesia, postural imbalance, etc. Gait disorders can generally help determine how far the neurological disorder has affected the motor function and control of the individual. Many physicians in general c linics determine if a patient has PD or if it has
