Parkinson's disease is one of the most common nervous system disorders. This disease is part of a group of conditions called motor system disorders. Motor system disorders are the result of the loss of dopamine-producing brain cells. Dopamine is a neurotransmitter. It acts as a chemical messenger in transmitting signals in the brain and other areas of the vial. Dopamine is found in humans as well as animals, including vertebrates and invertebrates. More information about dopamine can be found by visiting http://www.news-medical.net/health/What-is-Dopamine.aspx. There are four main symptoms of Parkinson's disease, which include (1) tremors in the hands, arms, legs, jaw and face, (2) rigidity or stiffness of the limbs and trunk, (3 ) bradykinesia or slowness of movements, and (4) postural instability or balance and coordination disorders. Parkinson's disease is considered chronic and progressive, meaning it is constant and does not go away and will only increase the intensity and severity of symptoms as the disease persists. Most cases of Parkinson's disease result from a combination of genetic and environmental factors, many of which have not been identified. The National Institute of Neurological Disorders and Stroke (NINDS) has published several informational articles on Parkinson's disease, available at http://www.ninds.nih.gov/disorders/parkinsons_disease/parkinsons_disease .htm. More than a dozen genes have been identified. identified to influence the risk of developing the disease if they are modified. Genes found in the Parkinson's disease gene family have diverse functions in the brain, as well as active functions in other organs and tissues. .... in the middle of paper work, work in the medical industry and other fields that require stable and stable manual control. The Michael J. Fox Foundation website allows people to post comments and I was touched by that strength. what these people did. Jo Dee Biddle, caregiver and loved one of a Parkinson's patient, posted: "If I've learned anything about Parkinson's in 28 years, it's to take things one day at a time. If it's a good day, seize it. If not, don't apologize. » I think this is such an inspiring way to look at daily life with Parkinson's. This attitude and approach will make the good days with this illness even more pleasant and the more difficult days easier to live with. There is much unknown about this disease, but there are many foundations and research efforts that support the cause of research and the continued search for early diagnosis..
