Can Caffeine Reduce the Chances of Parkinson’s Disease? A Review

Finding therapies for preventing Parkinson’s Disease (PD), a major neurodegenerative disease, remains an important way to improve the quality of life and reduce the total number of those afflicted with PD worldwide. Caffeine, one of the world’s most consumed psychoactive drugs, affects neurological pathways that are involved in PD. In this review, we explore the relationship between caffeine and PD, its mechanisms, and how the onset of PD is affected by the consumption of caffeine. We propose that daily caffeine consumption may reduce the risk of developing PD later in life, but that the neuroprotective effect varies by several factors. Understanding the effects of caffeine and how it impacts PD may provide insight into potential treatments or delay the onset of disease
