unilateral neglect

a disorder resulting from damage to the parietal lobe of the brain and characterized by a loss of conscious perception of objects or stimuli on the side of the body (usually the left half) that is opposite the location of the lesion. For example, if approached from the left side, an individual with unilateral neglect may not notice the approaching person, but would respond normally when approached from the right side. The disorder may be accompanied by alien limb syndrome and other striking neuropsychological features. Also called hemineglect; hemispatial neglect; spatial neglect. See also motor neglect; sensory neglect; visual neglect.
