Structural MRI correlates of cognitive impairment in patients with multiple sclerosis: A Multicenter Study.
In a multicenter setting, we applied voxel-based methods to different structural MR imaging modalities to define the relative contributions of focal lesions, normal-appearing white matter (NAWM), and gray matter (GM) damage and their regional distribution to cognitive deficits as well as impairment of specific cognitive domains in multiple sclerosis (MS) patients. Approval of the institutional ...
متن کاملMRI correlates of cognitive dysfunction in multiple sclerosis patients.
Studies with conventional magnetic resonance imaging (MRI) support the hypothesis that cognitive impairment in multiple sclerosis (MS) patients is related with the lesion burden. Patterns of frontal lobe cognitive decline were also found to be related with the corresponding regional lesion load, although the total lesion load on T2-weighted MRI scans of the brain seems to be more relevant in de...
متن کاملMRI Correlates of Disability in African-Americans with Multiple Sclerosis
OBJECTIVES Multiple sclerosis (MS) in African-Americans (AAs) is characterized by more rapid disease progression and poorer response to treatment than in Caucasian-Americans (CAs). MRI provides useful and non-invasive tools to investigate the pathological substrate of clinical progression. The aim of our study was to compare MRI measures of brain damage between AAs and CAs with MS. METHODS Re...
متن کاملGray Matters in Multiple Sclerosis: Cognitive Impairment and Structural MRI
Multiple sclerosis (MS) is an immune-mediated disease affecting central nervous system (CNS). Although MS is classically considered a white matter (WM) disease, the involvement of gray matter (GM) in the pathogenic process has been confirmed by pathology studies and MRI studies. Impairment of cognitive domains such as memory, mental processing speed, attention, and executive function can occur ...
متن کاملMultiple sclerosis, cannabis, and cognition: A structural MRI study
OBJECTIVE A subset of patients with multiple sclerosis (MS) smoke cannabis to relieve symptoms including spasticity and pain. Recent evidence suggests that smoking cannabis further impairs cognition in people with MS and is linked to impaired functional brain changes. No such association, however, has been reported between cannabis use and structural brain changes, hence the focus of the presen...
