Key takeaways
- Research on the connection between alcohol and Parkinson’s disease is varied, with some studies suggesting moderate consumption might lower risk, while others link heavy or prolonged use to increased risk.
- Small amounts of alcohol may temporarily ease motor issues by increasing dopamine, while long-term or heavy use can worsen symptoms by depleting dopamine levels.
- If you have Parkinson’s disease, it’s important to discuss alcohol consumption with a healthcare professional, as excessive drinking can interfere with medications and exacerbate symptoms, but moderate intake may be tolerated by some individuals.
Parkinson’s disease is a neurodegenerative disease that affects movement and is caused by a loss of dopamine-producing cells in the brain.
Alcohol also affects dopamine. So, is it safe to drink alcohol if you have Parkinson’s disease? The answer isn’t so simple.
Does alcohol consumption increase the risk of developing Parkinson’s?
For decades, researchers have been investigating the link between Parkinson’s disease (PD) and alcohol consumption, with complex and often conflicting results.
Some studies have shown no link between the two, while others suggest that moderate alcohol consumption (5 to 29.9 grams [g] per day) may actually reduce the risk of Parkinson’s disease. Other evidence suggests that heavy (more than 30 g per day) or prolonged alcohol use increases the risk.
A large European study from 2020 found that men with moderate lifetime alcohol consumption had a higher risk of developing Parkinson’s compared to light drinkers. Still, the results didn’t establish a significant link between alcohol consumption and the risk of Parkinson’s.
An analysis of 11 studies found that alcohol consumption was linked to a slightly reduced risk of Parkinson’s disease. And different types of alcohol may cause different effects.
For instance, two studies in the analysis found that beer consumption, in particular, was associated with a reduced risk of Parkinson’s disease, while wine or liquor were linked to an increased risk. However, some of these results weren’t statistically significant. In four other studies, no difference was found between beer, wine, and liquor.
Overall, the authors found that a decreased Parkinson’s disease risk was only associated with beer consumption but not liquor and wine. This may be because beer has a much lower ethanol content but higher antioxidant levels, such as folic acid, niacin, purine, and other phenolics believed to mediate the neuroprotective effects of alcohol.
Beer is also associated with a high concentration of uric acid, which has been shown to have neuroprotective effects in animal studies.
Further, a 2026 meta-analysis suggests that light to moderate alcohol consumption — particularly wine and liquor — may have a protective effect against Parkinson’s disease.
