I'm wondering are hemi-inattention, hemispatial neglect, unilateral neglect and visual neglect synonymous?

Hemispatial neglect: is also called hemiagnosia, hemineglect, unilateral neglect, spatial neglect, contralateral neglect, unilateral visual inattention,hemi-inattention, neglect syndrome or contralateral hemispatialagnosia. Reduced awareness of stimuli on one side without sensory loss most commonly follows a "stroke" or hemorrhage of the other side of the brain. See http://m.jnnp.bmj.com/content/75/1/13.full for more.
