Half of Reality Disappears for People During This Altered State of Consciousness
Hemispatial neglect is a post‑stroke neurological syndrome in which the brain ignores half of the visual or bodily world, rather than a visual defect. It occurs in roughly 43% of acute right‑hemisphere strokes and 20% of left‑hemisphere strokes, manifesting as egocentric (body‑side) or allocentric (environment‑side) neglect. Diagnosis relies on simple bedside tasks such as clock‑drawing, tactile comparison, and visual field checks. Emerging rehabilitation approaches—including targeted gaze training and virtual‑reality gaming—have shown measurable gains in patients’ left‑side awareness and functional performance.
