What are Parkinson’s Disease Causes?

Abstract

Parkinson’s disease (PD) is a progressive neurological disorder that results from the loss of dopamine-producing neurons in the brain. While the exact cause of PD is not fully understood, research suggests that a combination of genetic, environmental, and lifestyle factors may contribute to its development. Genetic mutations in certain genes, including Leucine-rich repeat kinase 2 (LRRK2), Alpha-synuclein (SNCA), and Parkin, have been linked to PD, although they account for only a small percentage of cases. Exposure to toxins such as pesticides and herbicides, head injuries, advancing age, male gender, diet, and a history of smoking have also been identified as potential risk factors for PD. Overall, it is likely that PD results from a complex interplay of factors that lead to the loss of dopamine-producing neurons in the brain, resulting in the characteristic symptoms of the disease.
