(WKRC) – Researchers have found a significant link between exposure to so-called “forever chemicals” and an increased risk of developing multiple sclerosis, according to a new study published in the journal Environment International and reported by PEOPLE.
The study highlights the potential impact of synthetic compounds commonly found in nonstick cookware and waterproof clothing on long-term health.
The research, led by Kim Kultima in Sweden, focused on two major environmental toxins: perfluorooctane sulfonic acid, known as PFOS, and polychlorinated biphenyls, or PCBs. Kultima said several individual substances, including PFOS and two hydroxylated PCBs, were associated with increased odds of multiple sclerosis.
Researchers found that people with the highest concentrations of the chemicals had about twice the odds of being diagnosed with multiple sclerosis compared with those who had the lowest concentrations.
Multiple sclerosis is a chronic autoimmune disease that disrupts communication between the brain and the body and can cause symptoms including numbness, weakness and vision changes.
The study analyzed blood samples from about 900 people recently diagnosed with multiple sclerosis and compared them with samples from people without the disease.
