Hemispatial neglect alters visual perception by causing individuals to ignore one side of space
Hemispatial neglect alters visual perception by causing individuals to ignore one side of space, typically contralateral to a cerebral lesion.
The retrieved papers overwhelmingly support the standard clinical definition of hemispatial or unilateral spatial neglect as a neuropsychological disorder where patients fail to attend to or perceive stimuli on one side of space, usually contralateral to a brain lesion.

Paper 0 establishes that spatial neglect is a neuropsychological disorder characterized by a failure to attend, respond, or perceive stimuli in the space contralateral to a brain lesion, typically manifesting as left-sided neglect.
