Understanding the risk and protective factors associated with Parkinsons disease (PD) is crucial for improving outcomes for patients, individuals at risk, healthcare providers, and healthcare systems. Studying these factors not only enhances our knowledge of the disease but also aids in developing effective prevention, management, and treatment strategies. This paper reviews the key risk and protective factors associated with PD, with a particular focus on the biological mechanisms underlying these factors. Risk factors include genetic mutations, racial predispositions, and environmental exposures, all of which contribute to an increased likelihood of developing PD or accelerating disease progression. Conversely, protective factors such as regular physical exercise, adherence to a Mediterranean diet, and higher urate levels have demonstrated potential to reduce inflammation and support mitochondrial function, thereby mitigating disease risk. However, identifying and validating these factors presents significant challenges. To overcome challenges, we propose several solutions and recommendations. Future research should prioritize the development of standardized biomarkers for early diagnosis, investigate gene-environment interactions in greater depth, and refine animal models to better mimic human PD pathology. Additionally, we offer actionable recommendations for PD prevention and management, tailored to healthy individuals, patients diagnosed with PD, and healthcare systems. These strategies aim to improve clinical outcomes, enhance quality of life, and optimize healthcare delivery for PD.
