TL;DR
This paper introduces a new computer-based method called Keen Eye to better detect visual neglect in patients with right hemisphere brain damage.
Contribution
The study validates a dual-task computer-based method that improves detection of subtle or hidden visual neglect cases.
Findings
The Keen Eye method showed high sensitivity and specificity in identifying neglect patients.
The method revealed quadrant-specific and vertically biased omissions in neglect patients.
Attention-demanding computer-based tasks improve diagnostic precision for visual neglect.
Abstract
Visual neglect is a common and disabling consequence of right hemisphere damage. Standard paper-and-pencil assessments may fail to detect subtle or well-compensated cases of neglect, especially under low attentional demands. This study presents and validates the Keen Eye computer-based method for diagnosing neglect using a dual-task paradigm. The method involves the simultaneous detection of lateralized visual targets and identification of centrally presented digits, increasing attentional load and sensitivity to spatial biases. We tested 102 patients with right hemisphere damage (38 with neglect, 64 without) using a predefined set of target positions that systematically varied across the visual field. Classification models based on error patterns and asymmetry coefficients demonstrated high sensitivity and specificity in distinguishing patients with neglect. The method also revealed…
