Scientists Link Early Relapsing-Remitting MS to Subtle Brain White Matter Changes Undetectable by Standard MRI
European scientists have identified subtle metabolic changes in the brain's white matter in individuals with early relapsing-remitting multiple sclerosis (RRMS). These changes, which involve tissue rich in nerve cell projections, were detected using a specialized noninvasive imaging technique called proton magnetic resonance spectroscopy (1H-MRS), even when standard MRI scans appeared normal. The study, published in *Acta Neurologica Belgica*, found metabolic abnormalities in white matter that varied by brain region, reflecting mixed patterns of tissue injury. While some changes correlated with cognitive function, these relationships were generally weak. Stronger associations were observed with a combined measure of physical and cognitive function. The researchers noted that these findings are preliminary and require confirmation through larger, long-term studies. Multiple sclerosis is a chronic condition where the immune system attacks myelin, the protective coating around nerve fibers, leading to various...
