Parkinson's patients try antioxidant supplements to boost brain health

This study looked at whether nutritional supplements, specifically N-acetyl cysteine (NAC) given orally and intravenously, could support brain function in people with Parkinson's disease. The researchers measured dopamine activity and markers of inflammation in the brain using special scans. 51 participants were randomly assigned to receive NAC, standard care, or other oral supplements, though the oral supplement group was later dropped from analysis.
