Parkinson’s disease is not inherited across generations. Current epidemiological surveys, it is believed that about 10% of Parkinson’s disease patients will have a family history, but the vast majority of patients are sporadic cases exist and the chance of inheritance is only about 10%. Inheritance is mainly determined by the patient carrying a susceptibility gene, which only leads to an increased probability of Parkinson’s disease, and does not mean that patients with a susceptibility gene will definitely develop Parkinson’s disease, and the incidence of patients will be higher than normal. The onset of Parkinson’s has more complex factors, such as genetic factors, environmental factors, neurological aging, the interaction of many factors for patients to develop, if the patient has a family of Parkinson’s disease should be promptly examined.
