• "In total, researchers identified 83,674 Medicare beneficiaries with incident Parkinson’s disease, with 434 new cases per 100,000 people in the highest exposure group, compared with 359 new cases per 100,000 people in the lowest-exposure group. The relative risk for Parkinson’s disease increased in the highest quartile of PM2.5 by 25%, compared with the lowest quartile after adjusting for factors such as age, smoking status, and health care usage (95% confidence interval, 20%–29%)."

VitaminDWiki - Overview Parkinson's and Vitamin D contains

• Vitamin D associated with Parkinson’s Disease in 55 studies, more studies needed- March 2022
• Parkinson's category has 112 studies
• Parkinson’s Disease and Vitamin D – review of 52 studies – May 2022
• Parkinson patients: 60 % taking Vitamin D – Dec 2019
• Low Vitamin D increases Parkinson's by 3X– July 2010 "only" a 30 year test, need more study
• Parkinson's disease prevented by Vitamin D, but small doses do not treat it - Aug 2023
• 10 clinical trials for PD with vitamin D intervention as of June 2023
• Parkinson’s Disease Summer School – alternative therapies included 60-80 ng of Vitamin D – Sept 2019

• Note by the Founder of VitaminDWiki: I have twice recommended lots of Vitamin D to treat PD. Both got much better, but one had his doctor him cut back to just 2,000 IU. All of his recovery got reversed. With lots of vitamin D he could sing and bike, but now he can barely talk or walk
