A fascinating new study delves into the relationship between smoking, alcohol consumption, and the risk of Parkinson’s disease (PD). The researchers analyzed data from over 3.9 million patients to assess the influence of changes in smoking and alcohol consumption on PD risk. Surprisingly, the study found that sustained smokers, regardless of intensity, had a lower risk of PD compared to non-smokers. Similarly, sustained drinkers, especially at light or moderate levels, showed a decreased risk of PD. Interestingly, even non-drinkers who started consuming alcohol lightly experienced a reduced risk of PD. Furthermore, individuals who initiated smoking or drinking, as well as those who did both, also displayed a decreased risk of PD. The study highlights the need for further research to unravel the mechanisms behind the protective effects of smoking and alcohol consumption on PD.

ObjectiveThere have been no studies on the association between changes in smoking and alcohol consumption or combined changes in smoking and alcohol consumption frequencies and PD risk. To assess the influence of changes in smoking and alcohol consumption on the risk of Parkinson’s disease (PD).MethodsNational Health Insurance Service (NHIS) database between January 2009 to December 2011 was analyzed. A total of 3,931,741 patients were included. Study participants were followed up for the incidence of PD until December 2017.ResultsCompared to the sustained non-smokers, sustained light smokers (adjusted hazard ratio [aHR] 0.80, 95% confidence interval [CI] 0.75–0.85), sustained moderate smokers (aHR 0.54, 95% CI 0.47–0.61), and sustained heavy smokers (aHR 0.49, 95% CI 0.44–0.55) had a lower risk of PD. Compared to those who sustained non-drinking, sustained light drinkers (aHR 0.85 95% CI 0.89–0.91), sustained moderate drinkers (aHR 0.68, 95% CI 0.60–0.78), and sustained heavy drinkers (aHR 0.77, 95% CI 0.68–0.87) showed decreased risk of PD. Among non-drinkers, those who started drinking to a light level were at decreased risk of PD (aHR 0.84, 95% CI 0.77–0.91). Among non-smoking and non-drinking participants, those who initiated smoking only (aHR 0.78, 95% CI 0.70–0.86), drinking only (aHR 0.77, 95% CI 0.68–0.87), and both smoking and drinking (aHR 0.69, 95% CI 0.58–0.82) showed decreased risk of PD.ConclusionSmoking is associated with decreased risk of PD with a dose–response relationship. Alcohol consumption at a light level may also be associated with decreased risk of PD. Further studies are warranted to find the possible mechanisms for the protective effects of smoking and drinking on PD, which may present insights into the etiology of PD.
