Spatiotemporal characteristics of the neural representation of event concepts.

Events are a fundamentally important part of our understanding of the world. How lexical concepts denoting events are represented in the brain remains controversial. We conducted two experiments using event and object nouns matched on a range of psycholinguistic variables, including concreteness, to examine spatial and temporal characteristics of event concepts.

Outcomes of endovascular thrombectomy in patients selected by computed tomography perfusion imaging - a matched cohort study comparing nonagenarians to younger patients.

Background: Endovascular thrombectomy (EVT) is efficacious for appropriately selected patients with large vessel occlusions (LVO) up to 24 hours from symptom onset. There is limited information on outcomes of nonagenarians, selected with computed tomography perfusion (CTP) imaging.

Methods: We retrospectively analyzed data from a large academic hospital between December 2017 and October 2019.

Rapid Arterial Occlusion Evaluation Scale Agreement between Emergency Medical Services Technicians and Neurologists.

Background: Rapid arterial occlusion evaluation (RACE) scale is a valid prehospital tool used to predict large vessel occlusion of major cerebral arteries in patients with suspected acute stroke. RACE scale administered by Emergency medicine services (EMS) technicians in the prehospital setting correlates well with NIH Stroke Scale score after patient arrival at a hospital. Despite this, the RACE scale is often characterized as too difficult for EMS technicians to accurately utilize.

Specific clinical phenotypes in relapsing multiple sclerosis: The impact of relapses on long-term outcomes.

Objective: The impact of relapses on the disease course of relapsing MS remains to be determined. This study aims to identify and characterize clinical phenotypes of relapse onset MS in a longitudinally studied cohort.

Methods: We recorded the clinical course of MS during the first decade of disease, using five-year epochs.

Relapsing multiple sclerosis patients treated with disease modifying therapy exhibit highly variable disease progression: a predictive model.

Objective: To describe a "new natural history" of multiple sclerosis (MS), characterizing three patterns of progression in Relapsing MS (RMS) patients during the "treatment era," using newly developed definitions. By utilizing our simple model we intend to predict which patients are most likely to reach an EDSS of 6.0.
