What are the causes of Parkinson disease?

What are the causes of Parkinson disease? What are the causes of Parkinson disease under the protection of the question? The answer, although there are many hypotheses about the cause of Parkinson disease, is not one of them yet proven. Recent twins studies and in the families of Parkinson patients indicate that there are people with a birth defect of the disease, and this imbalance can also be influenced by environmental factors. Strong family genetics of no chromosome 4 are the first proof that genetic change itself can lead to the development of Parkinson disease in some people. At about 15 % to 25 % of Parkinson disease, one of their family members also suffers from this disease.
