Definition
Hemiinattention is defined as the failure to report or respond to stimulation located contralateral to a brain lesion when the failure cannot be attributed to a primary sensory loss or motor impairment (Heilman et al. 1985). Patients with hemiinattention may be able to detect stimulation when their attention is drawn to stimuli in contralateral space, but they may become inattentive to stimuli in ipsilateral space. Hemiinattention implies that neglect is most pronounced in hemispace located opposite the brain injury.
