White matter and brain connection reductions may be cause of cognitive changes in MS

Despite approximately 2.3 million individuals worldwide currently living with multiple sclerosis (MS), the underlying mechanism behind the changes in cognition experienced, such as impaired concentration, attention, memory and judgment, have remained largely unknown. A new study, published recently in Neuropsychology, has revealed that the reduction in cognitive speed associated with all the common cognitive changes in MS may be due to a decrease in connectivity between network-specific brain regions. During the study, which was carried out by researchers at the Center for BrainHealth at The University of Texas at Dallas and The University of Texas Southwestern Medical Center (both TX,...
