Hemispatial neglect is a condition where you essentially ignore half of the world. Those who suffer from this may only eat half the food on their plate despite still being hungry. They may only draw half a picture and not realize that it is not complete. This syndrome is a result from damage to the brain, mostly from strokes. About 48% of patients with right hemisphere strokes showed symptoms of neglect. In the article it is not specifically stated why the patient does this. There is not a problem with their sight, but how their brain is processing what their eyes are seeing. People who have this condition typically show motor weakness and cognitive deficits as well.
