Since its identification in 1817, Parkinson's disease has impacted many and continues to destroy lives today. Here is some information about the causes and symptoms of this neurological disorder.
What Is Parkinson's?
Parkinson's disease is a degenerative disorder of the central nervous system. It was first identified in 1817 by an English surgeon named James Parkinson. As it progresses, it results in extreme damage to motor and speech skills as well as other bodily functions.
Theories/Speculation
A majority of people with this illness are believed to suffer from idiopathic Parkinson's, which means that there is no discernible cause. The most widely accepted theory today regarding the cause of Parkinson's is that it results from a combination of genetic and environmental factors.
Genetic Factors
A scientific study revealed that 15 percent of Parkinson's patients have at least one relative with the disease. Scientists have isolated three genes that, when mutated, result in the cell deterioration that defines Parkinson's.
Environmental Factors
Studies have linked certain conditions and chemicals to Parkinson's. Exposure to toxins may result in Parkinson's, including carbon monoxide, manganese, certain tranquilizers and cyanide. Some conditions that have been linked with Parkinson's include strokes, viral infections and head injuries.
Symptoms
Trembling is one of the most common symptoms, impacting approximately two-thirds of people diagnosed with the illness. Stiffness of the joints and limbs, similar to arthritis, is also very common. The rigidity highly impacts the muscles of the hands, which makes simple daily activities extremely difficult if not impossible. Many experience slurred speech and difficulty maintaining balance. Almost half develop mild to severe depression and sleep disturbances.
