Recent imaging studies in multiple sclerosis have focused on the association between cognitive dysfunction and grey-matter tissue loss, most notably of the cerebral cortex and thalamus. For example, at the American Academy of Neurology annual meeting, an analysis of the SPRINT-MS trial proposed that lower thalamic volume at baseline may be a useful predictor of physical, cognitive and visual disability in progressive MS (Nicholson et al. AAN 2022;S12.007). Thalamic volume at the time of relapse may also be predictive of cognitive recovery as assessed by the Symbol Digit Modalities Test (SDMT) (Weinstock et al. AAN 2022;P14.010). As such, thalamic volume (but not T2 lesion volume in this study) may serve as a marker of cognitive reserve. Read More

A number of new studies have provided data on the long-term safety and efficacy of high-efficacy disease-modifying therapies in MS. The data were presented at the American Academy of Neurology (AAN) annual meeting, held April 2-7 in Seattle, Washington. The following is a summary of key studies. Read More
