Abstract

Parkinson's disease (PD) is a complex neurological condition characterized by bradykinesia, stiffness, tremors, and non-motor symptoms. Despite ongoing studies, the precise etiology of PD remains elusive, and treatment options are limited. This narrative review exhibits the effect of several factors, like chronic constipation, use of nonsteroidal anti-inflammatory drugs (NSAIDs), pesticide exposure, smoking, exposure to head trauma, hyperuricemia, gout, cholesterol level, use of statin medications, caffeine consumption, on the risk of developing Parkinson's disease, including up-to-date studies. Constipation emerges as a potential prodromal symptom of PD, with studies revealing a positive correlation between persistent constipation and an increased risk of developing PD. NSAIDs, present conflicting evidence regarding their role in PD prevention. Pesticide exposure, particularly long-term exposure, is associated with an elevated risk of PD, with varying outcomes for different types of pesticides. Surprisingly, cigarette smoking exhibits an inverse correlation with PD risk, suggesting a potential protective role. The relationship between repeated head trauma and PD remains uncertain, with conflicting evidence from epidemiological studies. Uric acid, known for its anti-pro-oxidant properties, shows gender-specific associations with PD risk. Cholesterol's impact on PD risk is multifaceted, with studies presenting contradictory findings. Statin medications, despite their role in managing cholesterol, yield inconclusive results regarding their association with PD risk. Caffeine consumption emerges as a potential protective factor for PD. The conflicting findings underscore the need for further studies to fully understand them. These observations are correlational, and causation remains uncertain. Individual risk factors will depend on a unique genetic and health profile.
