Parkinson’s Diabetes Oxidative Stress: 8-OHdG Rose, F2-Isoprostanes Did Not
A 2026 meta-analysis of 54 human studies found that 8-hydroxy-2′-deoxyguanosine rose in Parkinson’s disease, while F2-isoprostanes did not show a statistically confirmed Parkinson’s signal; type 2 diabetes showed much larger peripheral oxidative-stress elevations than Parkinson’s disease for both biomarkers. Research Highlights Parkinson’s DNA-oxidation signal was moderate: Msigwa et al. pooled 5 Parkinson’s disease studies with …
