BACKGROUND Cognitive impairment is a common symptom of multiple sclerosis (MS), but the association between cognitive impairment and magnetic resonance imaging (MRI) disease measures in patients with relapsing-remitting (RR) MS is unclear. OBJECTIVES To study the prevalence of cognitive impairment and its relation with MRI disease measures in mildly(More)
PURPOSE To assess the capability of computed tomography (CT) in the prediction of irreversible ischemic brain damage and its association with the clinical course within 6 hours of stroke onset. MATERIALS AND METHODS Serial CT scans obtained within 6 hours of stroke onset, at 22-96 hours (median, 1 day), and at 2-36 days (median, 7 days) after symptom(More)
The objective of this study was to assess the effects of subcutaneous (sc) interferon beta-1a (IFNbeta-1a) on cognition in mildly disabled patients with relapsing-remitting multiple sclerosis (RRMS). Patients aged 18-50 years with RRMS (McDonald criteria; Expanded Disability Status Scale score <or=4.0) were assigned IFNbeta therapy at the physician's(More)
Diffusion Weighted Imaging is extremely important for the diagnosis of probable sporadic Jakob-Creutzfeldt disease, the most common human prion disease. Although visual assessment of DWI MRI is critical diagnostically, a more objective, quantifiable approach might more precisely identify the precise pattern of brain involvement. Furthermore, a quantitative,(More)
We designed a randomized, placebo-controlled, multicentre trial involving 51 relapsing-remitting multiple sclerosis patients to determine the clinical efficacy of mitoxantrone treatment over 2 years. Patients were allocated either to the mitoxantrone group (27 patients receiving I.V. infusion of mitoxantrone every month for 1 year at the dosage of 8 mg/m2)(More)
BACKGROUND AND PURPOSE The higher relaxivity of gadobenate dimeglumine compared with gadodiamide is potentially advantageous for contrast-enhanced brain MR imaging. This study intraindividually compared 0.1-mmol/kg doses of these agents for qualitative and quantitative lesion enhancement. MATERIALS AND METHODS Adult patients with suggested or known brain(More)
The objective of this study was to establish whether the time interval of 3 months is sufficient to detect whole-brain atrophy changes in patients with relapsing-remitting (RR) multiple sclerosis (MS). Another aim was to assess the value of monthly gadolinium (Gd)-enhanced magnetic resonance imaging (MRI) and of different Gd-enhancement patterns as(More)
BACKGROUND AND PURPOSE The hyperdense middle cerebral artery sign (HMCAS) is a marker of thrombus in the middle cerebral artery. The aim of our study was to find out the frequency of the HMCAS, its association with initial neurological severity and early parenchymal ischemic changes on CT, its relevance to clinical outcome, and the efficacy of intravenous(More)
Muscle quality is defined as muscle strength generated per unit muscle mass. If enzyme replacement therapy (ERT) has some effects on type II glycogenosis (GSDII) skeletal muscle pathology, we should be able to measure a change in strength and mass. We conducted a prospective study including 11 patients aged 54.2 ± 11.2 years, referring to a single(More)
PURPOSE Diffusion-weighted magnetic resonance imaging (DWI) is used to detect changes in the distribution of water molecules in regions affected by various pathologies. Like other conditions, ictal epileptic activity, such as status epilepticus (SE), can cause regional vasogenic/cytotoxic edema that reflects hemodynamic and metabolic changes. This study(More)
