Non-Genetic Risk Factors for Parkinson's Disease: An Overview of 46 Systematic Reviews

Yancong Chen et al.

Summary: This overview of systematic reviews and meta-analyses on non-genetic risk factors for Parkinson's disease (PD) development revealed that factors such as physical activity, smoking, coffee consumption, and certain medications can decrease the risk of PD, while factors like dairy intake, diabetes, and certain mental health disorders can increase the risk. The conflicting results in existing reviews were attributed to differences in study designs, emphasizing the need for improved and harmonized research in this area.
