By the progressive impairment or deterioration of neurons (nerve cells) in an area of the brain known as the substantia nigra cause parkinson’s disease These neurons produce a vital brain chemical known as dopamine when functioning normally,.Dopamine serves as a chemical messenger allowing communication between the substantia nigra and another area of the brain called the corpus striatum. This communication coordinates flat and impartial muscle movement. A lack of dopamine results in abnormal nerve functioning, causing a loss in the ability to control body movements.
Why Parkinson’s disease occurs and how the neurons develop into impaired is not known. Parkinson’s disease may be inherited However, there is escalating evidence Cause of Parkinson’s disease there is significant controversy surrounding the possibility of a genetic. In a small number of families, specific genetic abnormalities leading to the illness have been identified. However, the vast popular of people with Parkinson’s disease do not have one of these identified genetic abnormalities. It is probable that in people who develop Parkinson’s disease early in life (young-onset Parkinson’s disease) there is a genetic component. Because we don’t appreciate very much at this point about how Parkinson’s disease is inherited, the implications for children of people with Parkinson’s disease are unclear.
Certain toxins in the environment may cause Parkinson’s disease there is also some proof that. Scientists have suggested that external or internal toxins may selectively wipe out the dopaminergic neurons, causing Parkinson’s disease. Toxins that may be linked to Parkinson’s include manganese, carbon monoxide, carbon disulfide and some other pesticides.
It is slso supposed that oxidative stress can cause Parkinson’s disease. Oxidation is a process in which free radicals. Free radicals are normally shaped in the brain and body, but usually the brain and body have mechanisms to get rid of free radicals.
