Perhaps one of the most important questions posed by the neurobiology of aging concerns the pathogenic mechanisms in Parkinson's disease (PD). Recently, it was suggested that exposure to pesticides could be the main cause of PD. Another study reported Et the environmental endotoxin, lipopolysaccaride produced by Salmonella minnesota, m be a risk factor for PD. An alternative explanation is the genetic component, which has been suggested to be an important risk factor. Epidemiological studies have identified a positive family history of Parkinson as one of the most important risk factors for the disease. However, these studies neither examined nor reviewed the medical records of the family members. The twin study stated that the major factors in the etiology of PD are non-genetic, Meanwhile, egidemiological studies from China have shown that the prevalence of PD is much lower than in the Caucasian copulation, explained by the low frequency of cytochrome P-450 CYP2D6 debrisoquine hydroxylase gene polymorphism. The etiology idiopathic PD is still a question for scientists and calls for further research, especially WINtofeigrowing proportion of elderly and the rising incidence of PD worldwide. Future research for PD risk factors should consider that multiple interactions occur in PD, resulting in a complex trait, which includes genetic, acquired, and environmental components.
