According to researchers from the Barts Health NHS Trust and Queen Mary University of London, multiple sclerosis (MS) may actually be affected more by environmental factors than genetic ones, Techtimes reports.
In a study published in the Multiple Sclerosis Journal, they showed that certain races in east London have a higher MS prevalence rate compared to individuals living in their native countries, which is indicative of a strong influence that environment has on the disease.
MS is a neurodegenerative disease affecting the central nervous system and the most prevalent of chronic but non-traumatic causes of disability in young adults. The cause of the disease is not known but evidence suggests that both environmental and genetic factors are at play.
"Our early results suggest that environmental factors play a pivotal role in the risk of developing MS, whilst the individual genetic backdrop may be of lesser importance," said Dr. Klaus Schmierer, the study's lead.
