Study Links ‘Forever Chemicals’ to Multiple Sclerosis
A recent Sweden-based study reports that higher blood levels of certain *PFAS* and hydroxylated PCBs are associated with increased odds of being diagnosed with multiple sclerosis (MS), suggesting environmental toxins may contribute to disease risk, according to researchers involved in a large case‑control analysis of recent MS patients and matched controls.
What the Findings Mean and Next Steps
The study found several individual compounds, notably PFOS and specific OH‑PCBs, correlated with roughly doubled odds of MS in those with the highest concentrations, while analyses adjusted for lifestyle and genetic risk factors to isolate chemical exposure effects; investigators emphasize the need to evaluate combined exposures and regional differences and call for further research to confirm causality, explore biological mechanisms, and inform public health policies to reduce persistent pollutant exposure.
