Objective Increasing evidence shows that traditional neuropsychological tests are insensitive for detecting mild unilateral spatial neglect (USN), lack ecological validity, and unable to clarify USN in all different domains. Here we present a new, fully immersive virtual reality (VR) task battery with integrated eye tracking visual extinction assessment the acute state of stroke overthrow these limitations. Methods We included 11 right-sided patients 10 healthy controls aged 18−75 years. Three VR tasks named Extinction, Storage Shoot target were developed assess USN. Furthermore, examining various parts cognitive functioning was conducted measure general abilities. compared performance – those (USN+, n = 5) without (USN−, 6) ( 10) tentatively reported usability system stroke. Results Patients had mostly neurological symptoms. Nonetheless, found several differences between USN+ control groups performance. Compared controls, showed asymmetry gaze behavior detection times distinct locations. Extinction most evident extrapersonal space delayed on extreme left upper parts. Also, needed more time complete TMT A USN− B controls. acceptance rated high; no relevant adverse effects occurred. Conclusion New technology enables ecologically valid objective methods exact measures thus could potentially improve future clinical assessments.

Abstract The reported rate of the occurrence unilateral spatial neglect (USN) is highly variable likely due to lack validity and low sensitivity classical tools used assess it. Virtual reality (VR) assessments try overcome these limitations by proposing immersive complex environments. Nevertheless, existing VR‐based tasks are mostly focused only on near space analysis psychometric properties and/or clinical validation. present study evaluates a new task USN in extra‐personal examines neuronal correlates deficits far exploration. was administrated two groups patients with right ( N = 28) or left 11) hemispheric brain lesions, also undergoing paper‐and‐pencil assessment, as well group healthy participants. Our detected 44% cases compared 31% tests total sample. Importantly, 30% (with lesions) no clear sign performed outside normal range task. Voxel lesion‐symptom mapping revealed that VR were associated lesions insular temporal cortex, part neural network involved processing. These results show our efficient sensitive detecting mild strong manifestations affecting space, which may be undetected using standard tools.

Vertical neglect represents a visuospatial deficit occurring as possible consequence of acquired brain injury (ABI). Differently from unilateral spatial on horizontal space, vertical is poorly studied in the literature and rarely assessed clinical practice. In available studies, terms “radial,” “vertical,” “altitudinal” are often used interchangeably, although they do not describe same dimension. “Altitudinal” “vertical” refer to sagittal plane, whereas “radial” refers transverse plane. The term sometimes interchangeably with respect both axes. aim this systematic review was identify main characteristics after ABI, diagnostic tools used, treatment options. We also proposed clarification manifestations radial neglect. 23 articles reviewed, showed that occurred more frequently lower space than upper its presence associated neglect, it could occur compromise near being common. most frequent etiology vascular, particularly ischaemic. lesions side very heterogeneous include cortical subcortical areas all lobes, temporal lobe affected. With regard assessment tools, paper pencil tasks commonly recent years use computer-based increased. Taken together, our results suggest may be underestimated patients right hemisphere should always assessed, especially cases where patient shows signs important since can lead functional limitations everyday life, such poor wheelchair handling, stumbling over unnoticed obstacles located below (or above), walking down stairs, taking off shoes.

Patients suffering from Unilateral Spatial Neglect (USN) fail to pay attention to, respond and report sensory events occurring in the contralesional side of space. The traditional neuropsychological assessment USN is based on paper-and-pencil tests, whose data recording scoring may be subjected human error. utilization technological devices can expected improve USN. Therefore, we built Neurit.Space, a modified digital version three widely used detect signs USN, namely: Bells Cancellation, Line Bisection Five Elements Drawing Test. Administration processing fully automatic. Twelve right brain-damaged patients (six with six without USN) 12 age- education-balanced healthy participants were enrolled study. All administered both computerized versions tests. results this preliminary study showed good sensitivity, specificity, usability suggesting that these tests are promising tool for evaluation clinical research settings.

Abstract Background In neurorehabilitation, limited research exists on response performance and attention deficits in individuals with neglect across allocentric (aSC) egocentric (eSC) spatial coding frameworks. These are commonly assessed using pen-and-paper tests, which often fail to detect subclinical lateralized deficits. A computer-based task involving detecting shapes a cue-to-target paradigm offers precise sensitive data for identifying Methods This pilot study involved 18 right-handed healthy volunteers (HC) aged 23.89 ± 3.44 years, 13 right-hemispheric stroke (USN+) 32.83 4.45 10 but no (USN-) 32.6 5.18 who performed task. Response time (RT), accuracy rate (AR), visual perception deficits, reorienting disengagement were recorded analyzed. Results The USN + group had lower AR slower RT both aSC eSC conditions than the USN- HC groups fields cue types. Notably, showed greater delay left right (LVF) targets contralesional field ipsilesional field, pattern absent or HC. No significant differences total found between groups, took longer identify LVF eSC.
