    Recognition of longitudinal imaging changes of MS lesions has substantial implications for clinical management, but changes may remain below the resolution of human perception. In this study, the authors demonstrated that T2-weighted hyperintense lesions undergo dynamic change on MRI, with predominantly enlarging or contracting characteristics, more frequently seen in untreated individuals.

    Macro- and Microstructural White Matter Differences in Neurologic Postacute Sequelae of SARS-CoV-2 Infection
    Erin E. O’Connor, Rosangela Salerno-Goncalves, Nikita Rednam, Rory O’Brien, Peter Rock, Andrea R. Levine and Thomas A. Zeffiro

    In this cross-sectional study, SARS-CoV-2 infection effects on GM/WM volume, WM microstructure, cognitive performance, and peripheral cytokine concentrations were investigated. The study found that the NeuroPASC group had larger global and regional (prefrontal cortex and hippocampus) cerebral WM volume, more self-reported PASC symptoms, more headaches, lower psychometric performance, widespread higher mean kurtosis in WM microstructure, and different cytokine concentration profiles compared with controls. The authors conclude that immune dysregulation following SARS-CoV-2 infection might result in cerebral WM macrostructural and microstructural injury causing NeuroPASC clinical signs and symptoms.
