Correlation between fatigue and brain atrophy and lesion load in multiple sclerosis patients independent of disability.

2007

Abstract Background Fatigue is a major problem in multiple sclerosis (MS), and its association with MRI features is debated. Objective To study the correlation between fatigue and lesion load, white matter (WM), and grey matter (GM), in MS patients independent of disability. Methods We studied 222 relapsing remitting MS patients with low disability (scores ≤ 2 at the Kurtzke Expanded Disability Status Scale). Lesion load, WM and GM were measured by fully automated, operator-independent, multi-parametric segmentation method. T1 and T2 lesion volume were also measured by a semi-automated method. Fatigue was assessed by the Fatigue Severity Scale (FSS), and patients divided in high-fatigue (FS…

Brain atrophy and lesion load in a large population of patients with multiple sclerosis

2005

Objective: To measure white matter (WM) and gray matter (GM) atrophy and lesion load in a large population of patients with multiple sclerosis (MS) using a fully automated, operator-independent, multiparametric segmentation method. Methods: The study population consisted of 597 patients with MS and 104 control subjects. The MRI parameters were abnormal WM fraction (AWM-f), global WM-f (gWM-f), and GM fraction (GM-f). Results: Significant differences between patients with MS and control subjects included higher AWM-f and reduced gWM-f and GM-f. MRI data showed significant differences between patients with relapsing-remitting and secondary progressive forms of MS. Significant correlations bet…

Interobserver Agreement in the Diagnosis of Multiple Sclerosis

1989

• Interobserver agreement in the clinical diagnosis of multiple sclerosis (MS) among six neurologists was evaluated. Three of them participated in a study of the clinical diagnosis of MS, the Italian Multicenter Study (IMS). The raters examined the clinical forms of MS of 50 patients randomly selected from among 430 patients recruited from the IMS. For each patient, neurologists were asked to make a diagnosis according to the McDonald-Halliday classification system of MS. The overall agreement on the diagnosis (MS present or absent) was fair, with no difference noted between the two groups of raters. Considering the six diagnostic levels instead, the reliability was higher for the neurologi…
