Limbic Pathway Correlates of Cognitive Impairment in Multiple Sclerosis

Distinct injuries to various limbic white matter pathways have been reported to be associated with different aspects of cognitive dysfunction in multiple sclerosis (MS). Diffusion tensor imaging (DTI) offers a noninvasive method to map tissue microstructural organization. We utilized quantitative magnetic resonance imaging methods to analyze the main limbic system—white matter structures in MS patients with cognitive impairment (CI).
