Introduction: The study aimed to explore longitudinal cognitive outcomes and to ascertain predictors of conversion to dementia in a hospital-based mild cognitive impairment (MCI) cohort classified according to the neuropsychological phenotype at baseline.
Materials And Methods: Subjects aged >55 years who had a clinical diagnosis of MCI at initial visit between 2010 and 2018, with at least one formal neuropsychological assessment at baseline and follow-up of a minimum of 2 years were included. The prospective study was completed based on evaluation at last follow-up to gauge conversion to dementia, quantification of performance on activities of daily living and when available, longitudinal neuropsychological test scores.
Background: A non-invasive, reliable imaging modality that characterizes cavernous sinus dural arteriovenous fistula (CSDAVF) is beneficial for diagnosis and to assess resolution on follow-up.
Purpose: To assess the utility of 3D time-of-flight (TOF) and silent magnetic resonance angiography (MRA) for evaluation of CSDAVF from an endovascular perspective.
Material And Methods: This prospective study included 37 patients with CSDAVF, who were subjected to digital subtraction angiography (DSA) and 3-T MR imaging with 3D TOF and silent MRA.
Background: Cerebral microbleed (CMB) is a novel neuroimaging marker of cerebral small vessel disease.
Objective: To determine the prevalence of CMB in the subtypes of acute ischemic minor stroke (AIS) and transient ischemic attack (TIA) and to identify the risk factors associated with location and number of CMB.
Materials And Methods: Patients with AIS (National Institute of Health Stroke Scale of 5 or less) or TIA were included.
