Abstract

fetched live from OpenAlex

The question of post-lesion re-organisation of cognitive functions in cerebrovascular disease remains open. The aim of this study is to determine whether there is any connection between lesion lateralization and cognitive profile of stroke patients.205 patients (18-88 years old, 85 women) with cerebrovascular disease were assessed with the Russian version of Oxford Cognitive Screen (Rus-OCS) and Russian version of the Montreal Cognitive Assessment (Rus-MoCA). The scores on attention, memory, praxis, language and number processing domains have been obtained. Lesion lateralization was assessed by use of structural MRI scans from the Siemens Avanta 1,5 u0422 scanner.Patients with left hemisphere lesions showed lower scores on language and verbal subtasks whereas patients with right hemisphere lesions performed worse on a subtask on visuospatial functions. Analysis of the impairment ratios within each group confirmed these results. Patients with bilateral lesions demonstrated functional impairments typical of brain damage for either hemisphere but no isolated impairment to language or visuospatial processing. The results with lateralized deficits might help specialists with the selection of lesion-specific treatment methods.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
